When looking at the name Serverless, it may seem obvious what Serverless is; the lack of a server for an application. The name is actually quite deceiving, as Serverless applications still require servers to perform their duties. Serverless actually refers to a collection of managed cloud services that help to run our applications including storage, databases, functions, back and forth data transfer and more. With serverless, a cloud provider like Amazon Web Services, Google Cloud or Microsoft Azure handle all the configuration, provisioning and management of the server instead of the developer. In simple terms, this means organizations adopting a serverless architecture will be saving a lot of time and money by removing the need to worry about setting up and managing servers.
The Platform Development Team (part of the multimedia group at Oregon State University Ecampus) builds and maintains a number of platforms that leverage Serverless. Web Platforms are pieces of software that facilitate the creation and consumption of content or activities at scale. By using Serverless, our team has experienced a huge decrease in time needed to develop and deploy new platforms and applications. Without the need for our team to configure and manage servers we can handle the setup of our backend for new applications more quickly and efficiently. Any support needed for a dedicated server has also completely disappeared, that is now all handled by the cloud provider. Another huge money saver for our team has been the lack of need for a dedicated server (a server dedicated to you, not shared with anyone else). In the past when using a dedicated server, you would have to pay for both the server, in addition to any resources dedicated to that server, these costs continue to occur even when the server is not in use. With Serverless, you simply pay for what you use, this means when our applications are not receiving requests we are not being charged. When a serverless architecture is performing jobs, the costs accrued are very small, each job costing less than a fraction of a penny. The combination of both an increase in our speed to produce new applications and the lower price tag of using Serverless to handle tasks has allowed our team to undoubtedly save on development costs and provide software to users in a timelier manner.
Apart from its cost benefits, there are also many other positives to using a serverless architecture. These include security, scalability and accessibility. Because the server is no longer managed by the developer, many of the security aspects for applications that a developer would have had to manage in the past are handled by the cloud provider. There are still many security concerns a developer has to consider and handle outside of what the cloud provider handles, but Serverless helps reduce the list of concerns for the developer. Scalability is also a huge plus. As an application gets more popular or starts receiving more requests, Serverless allows scaling to handle those requests. With a dedicated server you would need to manually increase resources. Often when increasing the resources for a dedicated server there will likely be a good portion of those resources going to waste (wasted resources means wasted money), especially as the application receives different levels of traffic at different times. With Serverless, there is no need to worry about wasting resources because it only uses what is needed and scales to the amount of traffic an application is receiving. One of the main goals of our team is to make everything that we develop fully accessible. Serverless helps to us achieve this goal by being offering the ability to deliver content from different regions all over the world, rather than being dependent on a delivering all content from dedicated server located in Oregon. This allows students to more easily access our content and at higher speeds.
Ecampus’ Platform Development Team has seen so many benefits from using the serverless architecture over a dedicated server that it is now used in almost everything that we do. Every single one of our platforms including NES (our platform designed to handle long form content), SLIDE (our platform designed to add interactivity to slideshows), VDL (our platform designed to add interactivity to videos) and the upcoming interactive labs platform all have fully adopted a serverless architecture, which has helped us in producing interactive content for Ecampus’ courses in lightning fast speeds. We can also now utilize the time we have saved to improve our platforms and the overall interactive content that is used in Ecampus’ courses. In summary, Serverless has not only saved our team time and money but also has allowed us to offer better learning experiences to students taking Ecampus’ courses.
Audio is a term we all understand on some level. Commonly we think of audio as the transmission, reception, or reproduction of sound. Audible sound is what we hear. So, when we consider audio as an element of course design we are thinking about how sound can be used to communicate or support learning in an online course environment. Integrating audio in course delivery can be quite powerful if done well.
Perhaps the most common method of using sound in an asynchronous online course is via narrated lecture. The narrated lecture is typically a voice over a slide presentation or screencast. It can be an essential tool of instruction if designed effectively.
Another way the voice of an instructor can be incorporated into a course is via audio feedback on student assignments. These are short audio recordings that have been found to help build a sense of instructor presence in an online course.
Highly focused use of audio is also utilized in subjects where audio is, in essence, the topic at hand. Here we are considering language, music, and media arts courses as examples.
Other valued voices are often brought into the online learning experience via guest interviews in either audio or video format. Not to be left out, the voices of students are increasingly present in online course via tools such as VoiceThread and university provided video portals such as Kaltura Media Space. And with tools such as Zoom recording audio interviews and voice overs is easier than ever. With the availability of media platforms such as YouTube, Vimeo, Amazon Prime, Audible, and Apple Music and Podcasts the ability to bring external audio resources into the online experience seems almost limitless.
Audio is also used as a supporting resource for text-based content in online courses. In this case screen readers may typically provide the audio support. When using audio as a primary learning resource it is necessary to provide text-based transcripts as accessibility options. A fuller description of making audio accessible can be found at the W3C website.
The examples listed above are common ways we integrate audio elements into online learning. Are there other perhaps different ways we might consider? In the next few paragraphs we will explore a few ideas of how we might use audio in specialized ways in course design.
Specialized Audio Use
Orientation & Review Audio
Audio is a great tool to use when smaller segments of media should be used to orient students to a part of an online course. Think about short, more ephemeral, voice messages that can be easily produced and updated from term to term as the course changes. These audio segments need not be highly produced but should be of good quality. This type of audio segment reconnects students with the instructor via voice.
Listen to the orientation audio sample below that was used in an online course: RE 270 – Outdoor Recreation Resources, Behavior and Values | Module III Orientation by Dr. Craig Rademacher; Northern Michigan University c. 2012. (00:02:56). [download orientation audio transcript from Temi.com]
Similar short segments of audio may be used to review sections of content. The review audio may be produced by instructors or students. These audio reviews may be used in preparation for an exam, major project, or collaborations within the course. The goal of such reviews may vary but certainly one goal would be to re-focus the listener to the task at hand while providing timely tips or learning objectives.
One of the things you may have noticed about the audio clip above is the integration of music to the orientation message. Purposeful music selections can support the emotional feel of a course or module being introduced. Music can also serve as an audio cue, or audio branding, for a course. So, selecting audio stingers, or music introductions, can highlight that a particular message or topic is coming or reinforce an emotional tone if carefully planned.
The primary benefit of using audio for orientation and review is that audio is less production intensive making it a quick way to provide feedback. Audio is also fairly easy to edit with a free cross-platform audio tool such as Audacity.
The oral traditions of learning go back centuries. Prior to print, learning was interwoven in spoken traditions, legends, and cultural stories. Today story remains a potent vehicle for learning. As you might imagine audio is a great vehicle for story.
An example of this is an Oregon State University political science course titled Governing after the Zombie Apocalypse which was designed and taught by Dr. Rorie Solberg. The story that underpins this course is that a natural disaster has caused the breakdown of the U.S. government. In response citizens must create a new government including a bill of rights and constitution. Students become the citizens creating that new government taking into account marginal populations such as the surviving zombies which are called “blues”due to their virus-caused color.
Audio is used creatively in the course by periodically inserting radio broadcasts about odd happenings around the country. Although not the heart of the effort of the course, these audio presentations, really imagined radio newscasts, provide situational tenor and decision points as students go about creating a new government. Listen to a segment of a mock radio broadcast below.
Mock radio broadcast excerpt: Story by Dr. Rorie Solberg. Produced by Oregon State University Ecampus. Voice acting credit: Warren Blyth (00:02:04)
This segment highlights how audio can be used to shape and carry a narrative through an online course. You might imagine how different narrative audio presentations may support history, literature, or science courses.
Soundscapes & Nature Sounds
Experiencing authentic places or environments is believed to be a valuable form of learning. This idea is a driving force behind field-based learning and experiential learning. Audio soundscapes provide access to authentic acoustic environments that can support online learning about the context of an environment. The environment may be urban, rural, or perhaps in a wilderness-like setting. Soundscapes may also be used to create sense of cognitive and emotional world building that can be used in instruction. Soundscapes typically feature a molar perspective of the acoustic environment.
Other, more specific sounds of nature are potentially positive resources for online instruction. Below is a sound sample of the call of a common raven. Listen to the raven’s call.
Audio recorded in the Beaver Basin Wilderness at Pictured Rocks National Lakeshore in Michigan in 2010 | Craig Rademacher. (00:00:26)
Now imagine how this simple recording may be utilized in a course. It might be used to help identify ravens from crows in an ornithology course. Perhaps this audio clip could be used to help communicate a sense of isolation for listeners studying wilderness values. Or, perhaps it could be used to introduce the poem by Edgar Allen Poe titled The Raven. In each case the audio would be used intentionally to deepen the context or experience of the learner.
Sound quality is an important factor when selecting and using audio in an online course. Audio files need to be of sufficient quality to clearly indicate what you are expecting students to hear. Poor audio, or a confusing sound recording, is experienced as distracting and student will likely tune out. Recording and editing audio does require some knowledge and practice. And there are many places where you can learn to produce audio. LinkedIn Learning offers courses in audio production, podcasting, and even how to select a microphone. So, if you are interested give it a try.
If you are not inclined to produce your own audio content there are resources available where you can find high quality audio for use in courses. Some of these resources are royalty free. Others may require licensing of audio for use.
We have reviewed how audio is commonly used in online courses and how we might think about new ways of integrating audio. As you explore the links to resources below start to think about your next course design. How can you augment the text and video you normally use with audio? How might you leverage voice, narrative, or soundscapes to connect online students to the context, authenticity, and humanity of learning? You might want to experiment with audio at first. Start small. If it works, then you will have truly found a sound idea for online course design.
There are several ways to find audio podcasts to review for inclusion in a course. Apple Podcasts is a dominant resource in this area. Apple streams over 750,000 podcast shows with over 20 million episodes. Google Play Music is another good resource. Podcast feeds can also be found simply by browsing for podcasts online.
Audiobooks are found in many online book seller sites such as Amazon (Audible.com). Additionally some more specific sites such as audiobooks.com also provide resources.
The Ecampus multimedia team researches emerging tools, and works with our sibling team of Instructional Designers to help support instructors. So lets take a moment to peek at tools we all might be using in the coming years for communicating with teammates from a distance.
Multimedia developers primarily use a paid tier of Slack (for instant messaging), Outlook (for email), and Zoom (for meetings with live video or audio). While we play around with many other emerging tools, I believe we’re using the same basic trio as most everyone else. Just wanted to be clear that I don’t have a revolutionary new secret tool in my back pocket which you must start using today. We’re all in the same basic boat at the moment.
CDT shares files through a variety of different online services. Documents are usually shared through Box, with Google Drive as a backup. Videos usually end up on Kaltura through OSU’s MediaSpace, but works in progress start out on Frame.io to leverage some handy features for time stamped feedback. We manage our team’s projects through Asana, and store final deliverable files with a wrap-up note in a private internal database tool (that our team created and maintains). So those are handful of tools that might be mentioned when working with us. You may have already been sent a Box folder to upload files into, or a frame.io link to comment on a video.
As we all settled into home office work back in March, there was an interest in new tools for social interaction. I was particularly interested in applications that were connecting Virtual Reality users with phone and desktop users. Mozilla, the creators of the Firefox browser, are quietly building up Hubs, which strikes me as the most promising tool in this space. It’s free, easy to learn, and offers a ton of excellent functionality. Stop by the experimental space I set up for my team. It features a 3D model imported from our sketchfab account, and a video from our YouTube account.
One of the developers of Hubs recently laid out the secret plan for this tool: to build up a persistent global 3D network to rival the world wide web. Exciting stuff for all you fans of the scifi metaverse, and the freedom of early web pages.
There are other interesting tools bubbling around at the moment in the VR space. Facebook is letting anyone sign up for the beta of a shared social universe for Oculus VR users called “horizon.” Microsoft acquired AltspaceVR, which mixes VR users with desktop users and has already hosted multiple conferences during the quarantine. If you’ve invested in a VR headset, it might be worth checking out the bustling communities in VR chat or Rec Room. The makers of Second Life tried out 2 approaches to VR (Sansar and High Fidelity), but recently changed course. My team is currently trying to schedule a time to try out Sketchbox in different VR headsets. I stumbled across “Somnium Space” while writing this blog post. It’s kind of crazy how many things are being developed, but… aren’t quite ready for mass consumption just yet.
There is a cognitive load problem with all the new tools bubbling up in these cauldrons around the world and begging for attention. While Mozilla Hubs is my favorite, it does take a few minutes to go through it’s tutorial and learn what all you can do. These days that’s a lot to ask of people who just seek the simplicity of walking into a room to meaningfully interact with other humans in a natural way. More and more I’m nervous about suggesting new tools to colleagues, because I know they’re already dealing with a lot. And I see a lot of folks casually making a notable pile of work for others without seeming to notice the strain. As a designer, I enjoy walking through a new tool, and once I determine it’ll be useful for others it is hard to appreciate how exhausting it might also be for them. I think the key mistake is to require others learn a tool before they can get back to whatever task they set out to do in the first place. Hopefully we can find ways to design simpler tools, and to help people enjoy learning useful new third party tools. Wait until you’re ready to jump into the ones I’m mentioning here, and take it easy on your coworkers.
Suggestions? Want to meet up and talk about this further, perhaps inside one of the tools mentioned above? Please just leave a comment, or send us an email – we’d love to hang out with you and explore what the world is cooking up!
Storytelling is a fundamental part of human culture. With the use of narrative and world building in an educational setting, we can imagine ourselves as one of the characters and better engage with the material at hand. In distance education, these tools can be powerful allies made stronger with a multimedia approach. In a typical lecture scenario, students are presented information in the form of topics and relationships, specific ideas and often jargon. All these things are a necessary part of learning and provide a framework for the course’s content as well as preparing them for the application of the material. But by using storytelling as a tool, student engagement can be brought to higher levels and create memorable experiences.
A great example of the storytelling approach is Rorie Solberg’s PS 110: Governing after the Zombie Apocalypse. The course deals with the rebuilding of government after a fictional zombie apocalypse. Her course might be a bit too relevant to modern society during a pandemic, as it takes a closer look at the effects of a global health crisis. The students of PS 110 have been ‘selected’ as delegates to a constitutional convention. They represent one of the four territories standing in the place of the former United States, and each student faces the challenge of writing a new constitution, under which a new democracy will be built. The duty of the students is to create the outlines of a new government, accounting for the new needs of the people in this post-apocalyptic environment and, should they find it necessary, addressing the shortcomings of previous governments from around the world. The class begins with the first meeting of the delegates and at no point is the fourth wall broken.
Leveraging multiple forms of media can reinforce the verisimilitude of these stories and provide different avenues for student engagement. Rorie’s course is making full use of what Ecampus’ Multimedia Team has to offer with press release designs, audio broadcasts, animation and an interactive voting simulator.
The audio broadcasts, released by “PZA News” after the collapse of mainstream media outlets, are made to sound like the work of amateur Ham Radio operators doing their best to keep their communities informed. With a distinct taste of Orson Wells’ “War of the Worlds” radio play, these broadcasts feature our very own Warren Blyth as not one or two, but all of the eleven different characters and voices featured therein. The broadcasts cover local issues, giving insight to how societies and communities have changed in light of a global disaster. By tackling social issues as well, these fictional news broadcasts provide a more complete context to the decisions these students will eventually make in drafting their constitutions. They must consider any long reaching effects of their specific wordings and how their policies may affect disadvantaged groups, even unintentionally. Rorie’s course goes beyond being placed into a simple setting and focuses on how her fictional characters would interact with each other and their environments.
In addition to audio there are written publications. While reading is typical in any class, written press releases allow students to read more stories taking place in their post-apocalyptic society. Multiple forms of media for news releases reinforces the world building aspect and contributes to a multi-dimensional, fleshed out feel to the course’s setting. An animation, depicting the daily life of the surviving population is also being developed for this course. This is another fun and engaging way to bring the class materials alive. What better way for students to understand their roles than to see for themselves how their constituents live.
Storytelling and world building can be powerful tools for both student engagement and learning that can create memorable experiences. Enriching stories with multimedia creates an immersive experience that entertains as much as it educates. Rorie’s PS 110 is an excellent example of storytelling, world building and leveraging media assets to enhance immersion.
This brief series of tips is meant to be a beginner’s overview for DIY home recording on webcam, with some additional options suggested if you want to take your video production even further.
Since this document may not cover every issue you encounter while acclimating to DIY video recording, we recommend contacting your school tech person for additional troubleshooting.
WHERE TO START
Wired connection via ethernet cable is best
If wired connection is not possible, having a clear line of sight to wifi router will give the best wireless connection
Disconnect any wifi devices that are not in use or needed.
Determine if your computer meets minimumsystem requirements for streaming software
Close all non-essential programs to free up more computer resources
Disconnect any external monitors if you are on a laptop and it is running slowly
Testing Your Tech
Does your computer have a built in webcam or do you have a 3rd party webcam?
Identify where your microphone is and talk towards it
Test the webcam and audio settings BEFORE your first recording.
Practice practice practice
The last recording will be better than the first
Making sure your voice is clear and easy to understand
Having a microphone helps with this
Smart phone earbuds have a built-in microphone that can help you with voice clarity
Airpods would also work when recording to an iPhone
PRESENCE AND ENVIRONMENT
Be aware of your environment.
Limit any background noise as much as possible.
Clean up your space and be aware of what is in the background of the video.
Rooms with carpets and drapes are best for audio.
Turn off lights and close windows that are behind you when you are recording.
If possible, turn on a light behind the camera.
Keep experimenting with lighting until you have a set up that works for you.
Try not to bump the desk, computer, camera, or microphone while recording.
Typing should also be avoided.
Do a test lecture and watch it.
See what works and what doesn’t.
If possible, get feedback from others
The more you practice, the more natural it will feel.
Run through what you want to say before you start recording.
Relax and be natural! Hopefully you are sharing knowledge that you are passionate about and we want that to show. (Remember that we are always our own worst critic, and your teaching team will bethere to help you with constructive feedback on how to help students best enjoy and learn from these videos.)
Have notes in front of you while you’re recording.
It is easy to get distracted or off topic, especially when you are uncomfortable.
Having notes in front of you while you record can help you stay on track.
These notes can be as vague or as detailed as you want, but avoid reading off of them directly and not looking at the camera.
For digital notation, use a handwriting tablet and stylus, or an iPad app works as well
About halfway through earning a master’s in education, I took a summer session class on digital storytelling. It ran over the course of three half-day sessions during which we were required to complete two digital stories. I had no great academic ambitions in my approach to these assignments. I was trying to satisfy a degree requirement in a way that worked with my schedule as a single mother of two teenagers working full time while earning a graduate degree.
My first story was a self-introduction. I loved this assignment. Even though I had one evening to complete it, I spent hours tweaking it. I enjoyed learning the tools. I enjoyed sharing my story with my classmates. Even after it was graded, I kept finding ways to improve it.
After completing the course, I began to study the use of digital stories in education. My personal experience had shown me that in completing my assignment I had to become comfortable with technology as well as practiced my writing, speaking and presentation skills. I also felt a stronger connection to my classmates after sharing my video and watching their videos.
The research on digital storytelling echoes my own experience. Dr. Bernard Robin, an Associate Professor of Learning, Design, & Technology at the University of Houston, discussed the pedagogical benefits of digital storytelling assignments in a 2016 article,The Power of Digital Storytelling to Support Teaching and Learning. His research found that both student engagement and creativity increased in higher education courses when students were given the opportunity to use multimedia tools to communicate their ideas. Students “develop enhanced communication skills by learning to organize their ideas, ask questions, express opinions, and construct narratives” (Robin, 2016). Bernard’s experience also finds that by sharing their work with peers, students learn to give and accept critique, fostering social learning and emotional intelligence.
Digital Storytelling as Educators
Digital Storytelling in online education shouldn’t be thought of as only a means of creating an engaging student assignment. Educators who are adept at telling stories have a tremendous advantage in capturing their student’s attention. In the following short video, Sir Ian McKellen shares why stories have so much power. Illustrated in the form of a story, he shares that stories are powerful for four reasons. They are a vessel for information, create an emotional connection, display cultural identity, and gives us happiness.
McKellen is a compelling narrator with a great voice. This story is beautifully illustrated. It reminds me of how I want my learners to feel when they are consuming the content I create. Even if for a moment, so engrossed, that they forget that they are learning. Learning becomes effortless. As he points out, a good storyteller can make the listener feel as if they are also living the story.
Digital Storytelling Assignments
There are lots of ways to integrate digital stories across a broad set of academic subjects. Creating personal narratives, historical documentaries, informational and instructional videos or a combination of these styles all have educational benefits. One of the simplest ways to introduce this form of assessment to your course is to start with a single image digital story assignment.
Here’s an example I created using a trial version of one of many digital story making tools available online:
Digital Story Making Process
The process of creating a digital story lends itself well for staged student projects. Here’s an example of some story making stages:
Select a topic
Find resources and content
Create a storyboard
Script the video
Narrate the video
Edit the final project
I created an animated digital story to illustrate the process of creating a digital story using another freely available tool online.
Recommended Resources & Tools
You will find hundreds of tools available for recording media with a simple search. Any recommended tool should be considered for privacy policies, accessibility and cost to students.
Adobe offers a free online video editor which provides easy ways to add text, embed videos, add background music and narration. The resulting videos can be easily shared online via a link or by downloading and reposting somewhere else. While the tool doesn’t offer tremendous flexibility in design, the user interface is very friendly.
Audacity is a free, open-source cross-platform software for recording and editing audio. It has a steeper learning curve than some of the other tools used for multimedia content creation. It will allow you to export your audio file in a format that you can easily add to a digital story.
Padlet allows you to create collaborative web pages. It supports lots of content types. It is a great place to have students submit their video stories. You have a lot of control during setup. You can keep a board private, you can enable comments, and you can choose to moderate content prior to posting. Padlet allows for embedding in other sites – and the free version at the time of writing allows users to create three padlets the site will retain.
A note first about storyboarding. Storyboarding is an essential step in creating a digital story. It is a visual blueprint of how a video will look and feel. It is time to think about mood, flow and gather feedback.
Students and teachers alike benefit from visualizing how they want a final project to look. It doesn’t have to be fancy. It is much easier to think about how you want a shot to look at this stage than while you are shooting and producing your video. A storyboard is also a good step in a staged, longer-term project in a course to gauge if students are on the right track.
This is a storyboard creation tool. The free account allows for three and six frame stories. In each frame, you can choose from a wide selection of scenes, characters, and props. Each element allows you to customize color, position, and size. Here’s a sample I created:
When pressed for time to develop course content, we tend to over-rely on text-based assignments such as essays and written discussion posts. Students, when working on Digital Storytelling assignments, get the opportunity to experiment, think creatively and practice communication and presentation skills.
For educators, moving away from presenting learning materials in narrated bulleted slides is likely to make classes more engaging and exciting for their students leading to better learning outcomes. Teachers work every day to connect with students and capture their attention. A good story can inspire your students and help them engage with the content.
I was uncomfortable when I received my first digital storytelling assignment. I didn’t really know how to use the tools, wasn’t confident I knew how or what to capture. I was sure it would feel awkward to narrate a video. But These assignments turned out to be engaging, meaningful, and the process is pretty straight forward. Introduce digital storytelling into your courses, even by starting small, and you are sure to feel the same way.
The use of PowerPoint and other similar presentation software, as a visual foundation for recorded narrated lectures for use in online courses is pretty common. These slide-based presentations typically present a series of individual slides that contain titles, visuals, and descriptive text or lists of bullet points with an accompanying voice-over recording. Using this approach to online content presentation seems familiar as it is a technology enabled extension of the traditional slide-based presentations instructors have used in a live classroom lecture. But narrated lecture for online presentation has some structural differences.
Whether transitioning a classroom lecture, or creating a new narrated lecture for online use, instructors at Ecampus are also encouraged to rethink their slide-based presentations. The recommendation is to create highly focused content and keep the duration of an individual narrated lecture presentation to about 10 minutes. This means a typical 50 minute classroom lecture may transition to several online narrated slide presentations as it is distilled down to 2-3 highly focused segments.
Including voice-over with a slide-based presentation builds instructor presence in an online course. Narrated lectures also incorporate best practices in accessibility, copyright, and visual formatting. In essence, this process takes a PowerPoint presentation, incorporates best practice elements, and adds narration. This new instructor narrated presentation becomes a multimedia learning element for their course that is delivered in video format.
Multimedia Learning Theory Redux
On the surface, all the previous work in creating a narrated lecture seems sufficient. However if we incorporate research on multimedia learning we may choose to do more with this staple of the online course; the narrated lecture.
In my previous article on the value of images in online learning I explained how online presentations that combine text, images, and titles are considered multimedia-based learning objects. Using written words with images on a PowerPoint slide with voiceover is also a form of multimedia learning. Given this it may be useful to revisit theory related to multimedia learning to see how it related to narrated lecture design. The model below illustrates how the Cognitive Theory of Multimedia Learning (Clark & Mayer , 2016) informs our understanding of multimedia-based learning.
The model indicates that people (i.e., learners) have two channels of cognitive processing: 1) for processing visual/pictorial material and 2) one for auditory/verbal material. Additionally, humans can only process a few bits, or pieces, of information in each channel at the same time. Learner engagement with pictorial and verbal information is linked to an individual’s ability to parse information from the multimedia and ultimately integrate it with prior knowledge…creating new learning. That parsing is linked to two things:
How we structure and deliver information during the design of multimedia and
The learner’s ability to engage the information in a way that compliments learning.
Let’s stop here for a moment.
Now think about what you just did in reading the text above and looking at the illustration provided. In this instance you called upon a single information channel, the visual channel of cognitive processing, to interpret the meaning of the text description of the visual model. Was that an easy process for you?
How hard would it be for students to process similar information acquisition through one channel….vision only? With the cognitive theory of multimedia learning in mind ask yourself this…How would adding audio narration impact cognitive processing? How would that impact learning? Let’s explore these ideas in the context of narrated lecture design.
Five Guiding Multimedia Principles
In an article titled Information Design with Teaching and Learning in Mind, Rune Petterson and Maria Avgerinou (2016) identify 12 important principles teachers should take into account when designing multimedia-based learning experiences. I have organized these multimedia-based learning principles into three sections in the table below. As you read through these 12 principles it becomes clear that not all of these apply to narrated lecture design.
Principles 1-4 address more general, or global, understandings about multimedia design and learning. Principles 5-7 address design factors directly related to combining text and images without narration in multimedia-base learning. The last five principles (i.e., 8-12) address how the spoken word is best integrated into multimedia design to be consistent with the cognitive theory of multimedia learning. Although all the principles are important to multimedia design for learning, the last five guiding multimedia principles are the most salient for narrated lecture design.
From Theory To Practice
Remember, the goal for instructors is to develop narrated lectures that enhance the multimedia-based learning experience. It is not simply to create a replication of the in-class lecture. Let’s look at the five guiding multimedia principles and how the ideas in the principles might shape how you can prepare your narrated lectures as online multimedia learning elements.
Temporal Contiguity Principle
This principle suggests that the most effective designs using narration and graphics place those two elements in temporal proximity. They are seen and heard at the same time. Seems obvious. But you must think through this principle and plan the sequencing and duration ofslides and narration accordingly. You must know what you want to say and when to say it in the context of the visual elements you have on your slides.
This principle affirms that presenting words as audio narration is more impactful than written text in describing graphics on a slide. They are particularly impactful when paired with animations.
In essence this principle helps guide design that takes advantage of both channels of information processing. This also helps manage cognitive load by freeing learners from trying to interpret written text and images via the visual channel only. If you absolutely have to use text with graphics on your PowerPoint slides keep text in short phrase form to avoid extensive reading and any potential cognitive overload.
This principle proposes addresses presenting narration and written text that says the same thing combined with images. The redundancy principles guides designers to select either narration or written text with the image on a slide for the best learning experience. Choose one method of delivering the word-based description of the image. Don’t use both.
Once again this principle is about managing, through design, the cognitive load of the media element. There are some complex scenarios where text only is a best option…see the Control of Processing definition.
This principle simply states that adding interesting, but non-essential, visual or word content can hurt learning. Narrated lecture design should avoid placing funny phrases, decorative images, excess lines, colors and sound effects and music that does not directly relate to the learning at hand of any particular slide.
Instructors should know what they want to say and design to maintain keep cognitive focus on that learning. We sometimes think these extra element keep attention but actually the opposite is true…they clutter and create distracting cognitive load.
Sometimes this principle is not fulfilled through good intentions. It often occurs when instructors wish to have multiple images of something on the same slide. Then they talk about each image individually in narration. It is much better design to put those extra images on a new slide and talk about it when it is the focus of the learning. This avoids visual overload and helps keep the pace of your presentation moving.
Creating a social conversation with learners softens the experience of learning via devices. It also helps build instructor presence in a lesson and the course. One of the best ways of achieving this via narration is to use a conversational tone.
Conversational tone in everyday life comes from an interaction that is authentic and casual. That is difficult to achieve in narration. Professional actors train to do this. Faculty at Ecampus are often provided with narration tips to help in this regard. Narrators are encouraged to have notes that guide their presentation but not encouraged to read a script verbatim. Not surprisingly, reading a narration is easily detected by the listener’s ear. You can personalize your narrated lectures by knowing what you want to say, practice it so you know when to say it, then just be yourself and let your personality come through.
Applying the personalization principle in design means thinking through and planning your conversation with the remote audience. Then practicing the delivery so it feels conversational. Learners will benefit from this narration design strategy.
Earlier in this article we posited that new learning is predicated upon the structure and delivery method of information to learners as well as the learner being able to engage with the provided information in a way that supports learning. In a very simple way we are saying that good design for learning presents content clearly and does not create barriers to information engagement by leaners.
Instructors are correct that it is good to focus initial narrated lecture design on the slide presentation preparation that reflect best practices in accessibility, visual formatting, copyright, and more. It is also valuable to think through the narrated lecture design in terms of cognitive load, potential barriers to learning, and how to positively impact the learner’s information processing.
The five guiding principles for narrated lectures help instructors identify ways in which they can design and intentionally use audio narration with text and images that compliments an understanding of cognitive learning theory. In doing so they create online narrated lectures that are more effective as multimedia-based learning experiences.

The Ecampus multimedia team creates animations to bring your thoughts and words to life. In virtual reality, creating these 3D objects and animations has become incredibly easy and fast.
The old ways … of power tool juggling
Developing “multimedia” often means using small aspects of many different tools. “Media” being a means of communication and the plural of medium: a means of doing something. To create an animation for your class, we quickly run through a long list of media.
Here’s an exhaustive run through of how the process works at the moment (feel free to skip to the next section! This is detailed): You would typically type up and email over a script that I take into Google Drive to edit and comment upon. You’d record audio in one of our sound booths, and I’d take the resulting sound files into Adobe Audition to equalize levels and remove background noise(s). Then I’d grab a pencil and sketch out a quick storyboard for each sentence to suggest visuals that could emphasize your point(s). Photographs of these sketches are edited in Photoshop and injected into another file on Google Drive.
And that is just the easy preparation portion. Depending on the animation style we’re going after, I’d dive deep into obscure programs I’ve learned to use over the past few decades – like Autodesk Maya / Mudbox / MotionBuilder / Meshmixer, Adobe Illustrator / Animate / Character Animator / Fuse / Dimension, Unity3D, the Procreate iPad app, Agisoft Photoscan, MeshLab, Instant Meshes, Mixamo, etc. … Simply trying to list the most commonly used apps is exhausting (much less all the other emerging apps we investigate, or the ones we mastered that went away. I still love you HyperCard, Director, and Flash!). Phew.
However the pieces of animation are generated, we still end up spitting out thousands of images or video files that have to be lined up in Adobe After Effects / Premiere / Media Encoder to assemble the final video that we can upload to YouTube or Kaltura and send to you.
What I’m saying here is: this whole process usually takes weeks or months. Or… we can just do it all in VR in an afternoon.
The new reality… of easy bake dreams
Tvori is an amazing tool to easily puppet objects and characters around in VR. You can record audio in directly, and export 4K videos, 360 videos, or animation data for all those old programs i mentioned above. The main reason I set out to write this blog post: was to promote Tvori. It offers an all-in-one easy pathway to making your own animatons in mere minutes. This amazing program runs about 20 bucks, and unlike the other (free) VR tools I’ll mention below – Tvori isn’t backed by a major corporation (*yet). I expect to be generating much more animation work for instructors with it, and hope to be advising you all on how to use it yourselves as you step into VR through your own office computers.
I’d say Tvori offers a level of animation comparable to an “animatic” – a movie industry term for quick and dirty approximations of what the final multi-million dollar film could look like. There’s a good chance animatics will be good enough for the bulk of concepts we wish to impart to students at the university level, with the added bonus that we can generate many of them in a single term. That said, maybe you’re curious what other creative tools are emerging in VR these days?
1) Whiteboard animations are a common request at Ecampus. Oculus Quill lets us draw and animate in this cartoon style in 3D (so it’s like our current 2D drawing tools, but we can move the camera around freely at any time, zoom-in endlessly,). This free tool for Oculus Rift users was updated last month to add a ton of new useful tricks.
We’ve already made fly-bys of 3D drawings in Google Tiltbrush, but we couldn’t actually animate the drawings directly (we just started recording, and moved our head through space). But both these programs are free and worth looking into.
2) In Oculus Medium, anyone can sculpt objects in the air at high resolution with weightless clay. If you own the Oculus Rift, this is an free and amazing tool for creating 3D objects. Now we can make things extremely fast and bring them into those old programs we’ve used for years.
Google Blocks is a similar free tool to quickly make solid low-resolution objects (it’s like Google Sketchup with VR ease and benefits). Upload them to Google Poly to share with the world (a service very similar to SketchFab or Microsoft’s Remix 3D). With these sculpting tools, and repositories of free creations, it’s a snap to gather the building blocks needed to start complicated animation projects. For example, we can bring any of these sculpted objects right into Tvori…
3) Final thought: you can use Google Earth VR to walk around any location on earth, while scaling up to Godzilla height or even zooming in and out from space. The multimedia team can record what you’re seeing and pointing at, along with your narration. While this isn’t a feature of the software (yet), we have the magic means to do it for you. (And we can also go back into Google Earth Studio to make a more polished and precise version of the path you traveled).
I hope this inspires you to go get a VR headset, come by our offices and try it out, or let us don the gear for you. We look forward to making your imagination a reality for students worldwide!
For this post, I will focus on two simple strategies you can use to improve motivation and engagement in your online course, narrative and world building. These terms are used frequently in games, as well as in literature, film and other domains. They are a powerful tool, easily applied to your existing course material or as you develop new content.
There are two kinds of world building I’d like to talk about; instructor-created narrative and student-created narrative. To set the tone for our thinking about this, I’ll start with a quote from Designing for Motivation.
“… if you increase autonomy then engagement will improve, if you increase competence then motivation will increase, and if you increase relatedness then wellbeing will be enhanced–these needs become the controllers we tweak and adjust to iterate on and improve experience.”
(Peters, D., Calvo, R. A., & Ryan, R. M. (2018) Designing for Motivation, Engagement and Wellbeing in Digital Experience. Frontiers in Psychology, 28 May 2018. DOI: 10.3389/fpsyg.2018.00797)
So how can we use world building to ‘tweak’ these three controllers?
Instructor-created narrative refers to the world or environment created by the course builder and determined by the story they are telling about that world. This world building can be for a particular course activity, but also keep in mind that your entire online course is a learning environment and you, as the course builder, have significant influence over how that world is curated. A colleague recently described how an instructor begins their course with the phrase, “Welcome scholars”. This sets a tone that is a competence-supportive environment with just two words. Tone is a commonly used tool for world building across many domains.
As a simple entry point for world building, I’ll start with a classic type of game, role-playing.
Consider setting up a role-playing scenario for one of your existing activities or assignments. What is the outcome you expect students to achieve from this activity? Imagine a situation (or world) where that outcome exists or can be applied. What does that situation look like? Now, imagine you are a student in that situation, what does this world look like? (See what I did there? Role playing!) How will your student interact with that world to achieve your outcome? Take a minute or two to note your answers to these questions. This is a good way to begin sketching out your narrative. Once your sketch is complete, you can begin moving the parameters and rubrics of your existing activity into this world.
The world you create for your scenario can be the ‘real world’ in a particular time period, a hypothetical political situation, a business/client relationship regarding a product, or a hypothetical world to resolve a physics problem. Here are some ways you can frame your thinking as you practice the above exercise:
Take the tools you have provided in the course content (competence) and use them to analyze the following situation (world building). “How would you apply what you learned this week to the following situation?”
Even better, “How will the situation change as a result of your decisions?”
A small change in wording can provide big changes in thinking. In the second bullet point, we have moved from applying the week’s content to a given situation to a personalized critical analysis.
The other side of the coin is allowing students to build on your narrative, or create their own. This is where you significantly impact autonomy. This is your world, you create the rules. You set the parameters that will focus student thinking toward the outcomes you hope for them to reach. The rules you set will determine the level of autonomy the student experiences.
For this exercise, you can continue with the role-playing scenario you built in the previous Brainstorm Exercise or choose another existing activity from a course. Let’s brainstorm some ways you can add autonomy to this activity.
A simple addition to the role-playing scenario we built previously would be to allow students to choose the role they will play. You have built a narrative, now let the student choose the character they will play to build on that narrative. If you need to keep things more focused, it is totally acceptable to restrict the roles to a list of options. Even with restrictions, is it possible for students to choose the gender, race or economic background of their character? What other characteristics can you think of that will help a student take ownership of the role?
For other kinds of activities, consider giving students the creative freedom to choose and build their own narrative. The instructor still defines the rules of the world and sets the outcome and rubrics for the activity. Can you open up the choices a student has to meet these outcomes? Allow students the autonomy to take ownership of how they get to your outcome, using your rubric as a guide.
For example, select a concept that was covered in the course. In your activity, allow students to choose where and how that concept can be applied. Let them build the narrative around the concept. Conversely, select a setting in the world, much like you would for the role-playing scenario. Allow students to choose the course concepts they want to apply in that setting and build a narrative around that. This strategy lends itself well to case studies. Rather than taking on a specific role, students become story creators, while still working with instructional concepts and within the rules defined by the instructor.
Group World Building
As I mentioned in my previous post, group work and community building (as modeled by gaming communities) are great ways to increase relatedness in a course. Community members are able to share their competence and, in turn, feel valued by that community. This is another great support of motivation.
All of the strategies discussed above can be applied to group work. You can set up the same role-playing scenarios, but this time multiple students will take on different roles and interact in those roles within their group community. Relatedness is impacted as decisions and actions taken by one student will affect the world that is being collaboratively built. Here are two examples from a media course I recently helped develop. They both reflect the range of complexity group world building can undertake.
Pitch Game (Group Discussion)
For your Initial Post in this discussion, pitch a new television show. Follow the parameters presented in class; including X+Y claims, audience description, sketch of the show’s audience and the ideal network for the show. For your Peer Response, you will take on the role of media buyer. Choose which network or streaming service you work for. Review all available show pitches. Decide which show you will purchase. Reply to the show you wish to purchase; identify the network you represent and write your reasoning why you want to make the purchase. Use course material to support your decision.
Trial Simulation (Group Project)
To better understand the ways in which civil law shapes the media ecosystem, we will enact a short trial simulation. The court of the Honorable Judge is an appeals court: this means that the FACTS of the case were decided by the TRIAL court. The question that will be litigated in class regards the law and the interpretation of those facts.
One student will take on the role of Plaintiff, another will be Defense and a third member of the group will be the Judge. Over the next two weeks, you will follow the posted schedule to present your arguments and answer questions from the Judge. Before proceeding, review the Debate Rules and Trial Facts documents. You will be expected to cite actual Supreme Courts cases to support your claims.
Hopefully, this blog has provided some simple entry points for using world building to increase autonomy, build competence, and improve relatedness in a course to improve motivation and engagement. I would love to hear what you come up with in the Brainstorm Exercises.
I am an avid gamer. For some time, I have been thinking about how engaging games are and whether this quality can be leveraged for other purposes; like instruction. Put more simply … What is it about games that makes them so engaging? Is there something about this that we can use as educators? Granted, these are not new questions.
Dr. Meghan Naxer recently posted a primer on Self-Determination Theory (SDT), Self-Determination Theory and Online Education: A Primer. I believe SDT does an excellent job describing much of what makes games so motivating and engaging. Indeed, games provide an excellent model of SDT and can inform us on how the three basic psychological needs (autonomy, competence and relatedness) might be met in learning environments. I hope to build on some of the concepts introduced in Meghan’s post.
This is the first in a series of posts on games as a model for SDT. In part 1, I look at the convergence of Autonomy, Competence and Relatedness in gaming and online learning in relation to building community and intrinsic motivation.
Autonomy: Open Worlds
Games are becoming increasingly complex, particularly in the arena of Open World games where players are allowed to choose their own paths (autonomy). Entire worlds, even universes, exist for you to immerse yourself in, each with their own history and internal logic. You are often thrown into a new world with few instructions.
For example, in the Open World game No Man’s Sky, millions of stars and planets are procedurally generated just for you, unique to your specific game. When this game begins, you appear on an alien planet next to a broken space ship. Your space suit is running out of oxygen. No instructions, just urgent messages from your onboard computer on toxicity and your decreasing oxygen levels.
The complexity of modern open world games is more than can be reasonably covered in a tutorial. Besides, a significant part of what makes the game engaging is the autonomous exploration and discovery. You decide how you will play the game, in what order you will do things and at what pace. Being told how to play the game is far less interesting.
Here is the internal logic of No Man’s Sky:
You’re in an alien environment.
It seems like you are alone.
There are problems to solve.
There is no instruction manual.
You must explore to solve these problems.
Think about that in comparison to your online students when they first enter your course. Online students do have instructions to help them get started. However, at first glance, it can seem like they are thrown in the deep end to figure things out for themselves. In a situation where intrinsic motivation is less clear, this can lead to frustration. That does not have to be the case. For gamers, there is one more bullet-point.
When you get stuck, you can turn to an online community.
If you were to talk to a gamer and describe your experience about how many times you ‘died’ trying to figure a game out, a common reaction would be something like, “Why would you do that? You know there’s a wiki, right?” Playing an online game today is not a solo venture, even if it is a solo game.
Relatedness: Gaming Communities
Online communities spring up around successful games to support players. A majority of large games have an accompanying Wiki, many of which are curated and updated by players. Various online communities exist to discuss specific games in forums and social media. Players discuss technical issues, the internal logic of a game, the lore and history of the game’s world, where to focus their efforts when starting, or the best order to do certain tasks for best success.
The point here is that given the resources, an intrinsically motivated group of people will figure out ways to help each other succeed. This speaks to Relatedness. In an environment where players are given maximum autonomy, they turn toward their community to support that autonomy and gain competence in that environment. Further, when given an opportunity to contribute to supportive communities, to share their competence, players feel valued as members of that community. So, can we create something like this environment in an online course?
Intrinsic Motivation: Sharing Competence
The challenge in my above summary is intrinsic motivation. There is something of an inherent motivation to play a game and get better at it. Though it can be less clear, online students also have intrinsic motivation beyond just ‘passing the course’. Community building can be a way to help students to discover and support these motivations.
Following the gaming example from above,
“Players discuss technical issues … where to focus their efforts when starting, or the best order to do certain tasks for best success.”
This is a good place to start building community. Simply encourage your students to share their success strategies in your course.
Formalize this by setting up a forum-style environment where students share their experiences, the process they used to solve a problem, the biggest stumbling block this week, or simply to ask each other for help. Much of this could also be accomplished through existing discussions or peer reviews by simply adjusting or adding language for students to draw from their own success strategies, “What did you discover this week that would benefit another student?”
Group work is another tool that can be used for helping students discover intrinsic motivation and build community. Challenge students to work together to apply this week’s content to something in their own lives, a subject of their choice. Trust them to find the problem that needs solving. This is similar to participation in a gaming community – sharing and building competence. But in this case, you are allowing students to build the narrative.
By giving students some autonomy in deciding the end product of their work, you are creating an opportunity for them to discover what drives them.
With all of these examples, it is perfectly reasonable to set the ‘internal logic’ of the environment; subject matter to be discussed, the completion goals, length of the project, rubrics for assessment purposes. The idea is to allow students more autonomy in determining how to get to these goals. All that you are really changing, compared to a typical assignment, is control of the narrative.
And that is a nice segue to the topic of my upcoming post, Part 2, Games as a Model for Motivation and Engagement – Narrative and World-Building
