What’s An Image’s Value?

Image of postcard with a picture is worth a thousand words written on it.

Have you ever created an online course without using images? No?

That is not surprising as images can convey emotions, ideas, and much more. Their value is often captured in an old adage: A picture is worth a thousand words.

This article will discuss the value of images in online course design and how using visuals to accompany instruction via text or narration might contribute to or detract from an online learning experience. Let’s begin.

Multimedia Learning: Images, Text, and More

Online learning is a modern form of multimedia learning. Richard Mayer (2009) described multimedia learning as that learning that integrates the use of words and pictures. In traditional classrooms these learning resources might be experienced as: 

  • Textbooks:  Text and illustrations.
  • Computer-based lessons: Narration w/animation
  • Face-to-face slide presentations: Graphics and audio.

In online learning multimedia may also include:

  • eBooks: Text and digital images 
  • Video: Text, images, animations, coupled with audio.
  • Interactives: Maps, images, and video.
  • Digital Visual Representations: Virtual worlds and 3D models.
  • Screencasts: Software demos, faculty video feedback, and more.
  • Audio: Enhanced podcasts or narrated lectures.

These two short lists, although not exhaustive, demonstrates the importance of visual elements to multimedia based learning in online courses. There are many reasons why we might include any one of these multimedia learning experiences in an online course. For our purposes we will explore a bit more the instructional value of visuals to online learning.

So, how do words and pictures work together to help shape learning? Given that this is perhaps the most common learning object used in an online course it would seem useful to understand what may be considered this simple interpretation of visual literacy for learning (Aisami, 2015).

Visual Engagement Of A Learning Object

In a recent study of how people acquire knowledge from an instructional web page Ludvik Eger (2018) used eye tracking technology to examine a simple learning object composed of a title (headline), a visual element (i.e., diagram), and a box of written text. With no audio support for the learning object in this study, participants engaged the content via visual engagement alone. Results indicated that the majority of students started their learning process at the headline or the headline and visual element. The box of information, in text form, was the third part of the learning object engaged.

Within this context eye movement analysis indicates a learning process that is dependent upon a consistent visual flow. Purposely connecting the title, visual element and information text of a learning object may best reinforce learning. By doing this the course designer/instructor becomes a sort of cognitive guide either focusing or not-focusing learning via the meaning structure of the various learning object elements. In our case we want to use visual elements to support performance and achievement of learning tasks.

Choosing Visual Elements

In order to explore the choice of visual elements in an online learning experience it is helpful to understand how we process that experience from a cognitive science perspective.

Clark and Mayer (2016) describe that cognitive science suggests knowledge construction is based upon three principles: Dual channels, limited capacity and active processing. Let’s briefly examine what these are.

Dual channels:

People have two channesl of cognitive processing 1) for processing visual/pictorial material and 2) one for auditory/verbal material. See Figure 1.  below.

 

Model of cognitive model of multimedia learning.
Figure 1.: Model of the Cognitive Theory of Multimedia Learning

Limited capacity:

Humans can only process a few bits of pieces of information in each channel at the same time.

Active processing:

Learning occurs as people engage in cognitive processing during learning. This may include attending to relevant material, organizing that material into a coherent structure, and integrating that material with prior knowledge.

Due to the limits on any learner’s processing capability it is paramount that we select visual images that help manage the learning process. Our goal is to limit excessive processing that clutters the learning experience, build visual support for representing the core learning process, and provide visual support that fosters deeper understanding of the learning at hand. What does this mean in practice?

Managing Processing Via Image Use

Making decisions about image selection and use is a key to managing this learning process. Understanding the meaning of images to select is also key and is really a function of literacy in one’s field and visual literacy in general (Kennedy, 2013).

In practice we can use the following guidelines to make decisions about image use in multimedia-based online learning. 

  • Control Visual Elements – Too many images on a web page or slide may force extraneous cognitive processing that does not support the instructional objective. 
  • Select Visual Elements Carefully – Images difficult to discern are likely to negatively impact learning. Think about good visual quality, emotional and intellectual message of the image, information value, and readability.
  • Use Focused Visual Elements – Target selection of visual support to those images that represent the core learning material and/or provide access to deeper understanding of that core content.

Other Image Tips

Emotional Tone: Emotional design elements (e.g., visuals) can play important roles in motivating learners and achievement of learning outcomes (Mayer, 2013).

Interest: Decorative images may boost learner interest but do not contribute to higher performance in testing (Mayer, 2013). Use decorative images prudently so they do not contribute to extraneous learning processing (Pettersson & Avgerinou, 2016).

Challenge: Making image selections that contribute to a degree of confusion may challenge learnings to dive more deeply into core learning. This is a tenuous decision in that challenge in sense making may prove to foster excessive processing.

Access: Images must be presented in a format that is viewable to users to be practical. This involves an understanding of technical features of image formats, download capability, mobile use, and universal design techniques.

Final Thoughts

It is valuable to remember that visuals communicate non verbally. They are most effectively used when carefully selected and paired with text or audio narration. Visuals appeal to the sense of sight. They have different classifications and could be pictures, symbols, signs, maps graphs, diagrams, charts, models, and photographs. Knowing their form, meaning, and application is part of being a visually literate course developer or instructional designer.

I pledge that I have acted honorably in completing this assessment.

There are two sides to the story of security of online assessments. On the one side, cheating does exist in online assessments. Examity’s president Michael London summarized five common ways students cheat on online exams:

  1. The old-school try of notes;
  2. The screenshot;
  3. The water break;
  4. The cover-up; and
  5. The big listen through devices such as Bluetooth headset (London, 2017).

Newton (2015) even reported the disturbing fact that “cheating in online classes is now big business”. On the other side, academic dishonesty is a problem of long history, both on college campuses and in online courses. The rate of students who admit to cheating at least once in their college careers has held steady at somewhere around 75 percent since the first major survey on cheating in higher education in 1963 (Lang, 2013). Around 2000, Many faculty and students believed it was easier to cheat in online classes (Kennedy, 2000), and about a third of academic leaders perceived online outcomes to be inferior to traditional classes (Allen & Seaman, 2011). However, according to Watson and Sottile (2010) and other comparative studies (Pilgrim & Scanlon, 2018), there is no conclusive evidence that online students are more likely to cheat than face-to-face students. “Online learning is, itself, not necessarily a contributing factor to an increase in academic misconduct (Pilgrim & Scanlon, 2018)”.

Since there are so many ways for students to cheat in online assessments, how can we make online assessments more effective in evaluating students’ learning? Online proctoring is a solution that is easy for instructors but adds a burden of cost to students. Common online proctoring service providers include ProctorU, Examity, Proctorio, Honorlock, to name just a few (Bentley, 2017).

Fortunately, there are other ways to assess online learning without overly concerned with academic dishonesty. Vicky Phillips (n.d.) suggested that authentic assessment makes it extremely difficult to fake or copy one’s homework. The University of Maryland University College has consciously moving away from proctored exams and use scenario-based projects as assessments instead (Lieberman, 2018). James Lang (2013) suggested smaller class sizes will allow instructor to have more instructor-to-students interaction one-on-one and limit cheating to the minimum therefore; Pilgrim and Scanlon (2018) suggest changing assessments to reduce the likelihood of cheating (such as demonstrating problem solving in person or via video, using plagiarism detection software programs like TurnItIn, etc.) , promote and establish a culture of academic integrity (such as honor’s code, integrity pledge), and supporting academic integrity through appropriate policies and processes. Kohnheim-Kalkstein (2006) reports that the use of a classroom honor code has been shown to reduce cheating. Kohnheim-Kalkstein, Stellmack, and Shilkey (2008) report that use of classroom honor code improves rapport between faculty and students, and increases feelings of trust and respect among students. Gurung, Wilhelm and Fitz (2012) suggest that an honor pledge should include formal language, state the specific consequences for cheating, and require a signature. For the honor pledge to be most effective, Shu, Mazar, Gino, Ariely, and Bazerman (2012) suggests including the honor pledge on the first page of an online assessment or online assignment, before students take the assessment or work on the assignment.

Rochester Institute of Technology (2014) ’s Teaching Elements: Assessing Online Students offer a variety of ways to assess students, including discussions, low-stake quizzes, writing assignments (such as muddiest point paper), and individual activities (such as staged assignments for students to receive ongoing feedback), and many other activities.

In summary, there are plenty of ways to design effective formative or summative assessments online that encourage academic honesty, if instructors and course designers are willing to spend the time to try out suggested strategies from literature.

First, let’s start by considering the characteristics of effective feedback in general. What comes to mind?

sound waves

Perhaps you hear in your head (in the authentically authoritative voice of a past professor) the words timely, frequent, regular, balanced, specific. Perhaps you recall the feedback sandwich–corrective feedback sandwiched between positive feedback. Perhaps you consider rubrics or ample formative feedback to be critical components of effective feedback. You wouldn’t be wrong.

As educators, we understand the main characteristics of effective feedback. But despite this fact, students are often disappointed by the feedback they receive and faculty find the feedback process time consuming, often wondering if the time commitment is worth it. As an instructional designer, I hear from faculty who struggle to get students to pay attention to feedback and make appropriate changes based on feedback. I hear from faculty who struggle to find the time to provide quality feedback, especially in large classes. The struggle is real. I know this because I hear about it all the time.

I’m glad I hear about these concerns. I always want faculty to share their thoughts about what’s working and what’s not working in their classes. About a year or two ago, I also started hearing rave reviews from faculty who decided to try audio feedback in their online courses. They loved it and reported that their students loved it. Naturally, I wanted to know if these reports were outliers or if there’s evidence supporting audio feedback as an effective pedagogical practice.

I started by looking for research on how audio feedback influences student performance, but what I found was research on how students and faculty perceive and experience audio feedback.

What I learned was that, overall, students tend to prefer audio feedback. Faculty perceptions, however, are mixed, especially in terms of the potential for audio feedback to save them time.

While the research was limited and the studies often had contradictory results, there was one consistent takeaway from multiple studies: audio feedback supports social presence, student-faculty connections, and engagement.

While research supports the value of social presence online, audio feedback is not always considered for this purpose. Yet, audio feedback is an excellent opportunity to focus on teaching presence by connecting one-to-one with students.

If you haven’t tried audio feedback in your classes, and you want to, here are some tips to get you started:

  1. Use the Canvas audio tool in Speedgrader. See the “add media comment” section of the Canvas guide to leaving feedback comments. Since this tool is integrated with Canvas, you won’t have to worry about upload and download times for you or your students.
  2. Start slow. You don’t have to jump into the deep end and provide audio comments on all of your students’ assignments. Choose one or two to get started.
  3. Ask your students what they think. Any time you try something new, it’s a good idea to hear from your students. Creating a short survey in your course to solicit student feedback is an excellent way to get informal feedback.
  4. Be flexible. If you have a student with a hearing impairment or another barrier that makes audio feedback a less than optimal option for them, be prepared to provide them with written feedback or another alternative.

What is it?

Image of animator’s face in Character Animator program showing the facial data points used for animation creation.

Facial motion capture (Mo-Cap) is a process that uses a camera to map and track points on the user’s face. Software such as Adobe’sCharacter Animator derive data from the camera to animate cartoon characters in real time. This can greatly reduce the amount of time needed to create an animation and breathes subtle life into the character that would be otherwise difficult to achieve. Character Animator harnesses the power of the webcam to map several parts of the face to the respective parts of the character allowing it to record in real time. This includes your eyebrows, eyes, mouth, and head position. It also intakes audio to change mouth shapes to match what the user is speaking. In addition to the webcam, the user can operate their keyboard to trigger additional movements, effects, and walk motions. All these different aspects combine and give the character a personalized feel.

How does it help?

Image of character being rigged into a puppet showing the mesh and body tags.

Cartoon animations currently do not have a large presence in online learning. This is mostly because they take a long time to create and not everyone has had the resources to create them. Normally, character animation for cartoons requires drawing each frame or using a pose-to-pose process called key framing. With innovative technology such as Character Animator, it greatly reduces the barrier to create cartoon animations for online learning. Each motion of the face records instantly and gives the character life by adding subtle movements to the face and head. The bulk of the work is completed early on to draw, rig, and add triggers to the character, or in this case, the puppet. Once the puppet is set up to record, it is smooth sailing from there. All movements, audio, and facial expressions are recorded in one take; greatly reducing the amount of time for development. However, Character Animator allows you to choose which aspects you want to record, so you can record the eye movements one time, then the eyebrows another time. This is helpful for the perfectionists out there who cannot seem capture it all at once.

How does it work?

To create an animation using Character Animator, there are a handful of stages to complete. The first step is to draw the character in either Photoshop or Illustrator. Next, Character Animator imports the graphics and they are rigged into puppets to prepare for recording. This means the eyes, nose, mouth, etc. are tagged with their respective labels. Also during this time, you can create keyboard triggers. These are animations such as arm movements, walk motions, and more, that the pressing of certain keys on the keyboard triggers the character to perform. After the puppets are prepared, it is time to record. It does not have to be shot perfectly all at once; you can blend the best bits from different recordings into one masterpiece. The last step is to export the character’s recording and composite it into a story using video software such as Premiere Pro or After Effects. Once you achieve the flow of facial Mo-Cap, you can start cranking out animations faster than ever before.

What can instructional designers learn from video game design? This might seem like a silly question—what do video games have to do with learning? Why might we use video games as an inspiration in pedagogy? As instructional designers, faculty often come to us with a variety of problems to address in their course designs—a lack of student interaction, how to improve student application of a given topic, and many more. While there are many tools at our disposal, I’d like to propose an extra tool belt for our kit: what if we thought more like game designers?

Video games excel at creating engaging and motivating learning environments. Hold on a minute, I hear you saying, video games don’t teach anything! In order for games to onboard players, games teach players how to navigate the “physical” game world, use the game’s controls, identify the rules of what is and is not allowed, interpret the feedback the game communicates about those rules, identify the current outcome, form and execute strategies, and a large variety of other things depending on the game, and that’s usually just the tutorial level!

What is the experience like in a learning environment when students begin an online course? They learn how to navigate the course site, use the tools necessary for the course, identify the assessment directions and feedback, identify the short-term and long-term course outcomes, learn material at a variety of different learning levels, and large variety of other things depending on the class, and that’s usually just the first week or two! Sound familiar? What are some things that video games do well during this on-boarding/tutorial to setup players for success? And how might instructional designers and faculty use these elements as inspiration in their classes?

The following list includes nine tips on how game design tackles tutorial levels and how these designs could be implemented in a course design:

  1. Early tasks are very simple, have low stakes, and feedback for these tasks is often very limited—either “you got it” or “try again”. Consider having some low-stakes assignments early in the course that are pass/fail.
  2. If negative feedback is received (dying, losing a life, failing a level, etc.), it is often accompanied by a hint, never an answer. If you have a MCQ, do not allow students to see the correct answer, but consider adding comments to appear if a student selects an incorrect answer that offers hints.
  3. If negative feedback is received, the game does not move on until the current outcome is achieved. Allow multiple attempts on quizzes or assignments and/or setup prerequisite activities or modules.
  4. Game levels allow for flexible time—different players complete levels at different rates. Design tasks with flexible due dates. Many courses already allow some flexibility for students to complete activities and assessments within weekly modules—can that flexibility be extended beyond a weekly time frame?
  5. Tutorial quests usually have predetermined and clearly communicated outcomes. All objectives are observable by both the game and the player. Create outcomes and rubric conditions/language that are self-assessable, even if the instructor will complete the grading.
  6. Tasks and game levels are usually cumulative in nature and progress using scaffolded levels/activities. Consider breaking up large assignments or activities into smaller, more cumulative parts.
    • For example, the first quest in The Elder Scrolls V: Skyrim is a great example for Nos. 5 and 6 above. It consists of four required objectives and two optional objectives:
      • Make your way to the keep.
      • Enter the Keep with Hadvar or Ralof.
      • Escape Helgen.
      • Find some equipment (Hadvar) / Loot Gunjar’s body (Ralof).
        • Optional: Search a barrel for potions.
        • Optional: Pick the lock of a cage.
  7. There are varying degrees of assumed prior knowledge, but no matter what, everyone participates in the tutorial levels. They are not optional. Consider saving optional “side quests” for later in a course or having an introductory module for everyone, regardless of skill level.
  8. The “tutorial” process usually ends when all skills have been introduced, but some games continue to add new skills throughout, inserting mid-game tutorials when necessary. Return to some of the design ideas on this list if a course introduces new topics throughout.
  9. After a requisite number of skills are mastered and players are able to fully play the game, the only major changes in design are increases in difficulty. These changes in difficulty are usually inline with maintaining a flow state by balancing the amount of challenge to the skill level of the player. As course material and activities increase in difficulty, make sure there are ample opportunities for students to develop their abilities in tandem.

Games are a great model for designing engaging learning experiences, with significant research in psychology and education to back it up. By understanding how games are designed, we can apply this knowledge in our course designs to help make our courses more motivating and engaging for our students.

Want to know more about the psychology of why these designs work? Start with these resources:

For Ecampus students, online education offers accessibility, flexibility and asynchronous learning opportunities when attending courses on campus may not be possible. University-based distance education has experienced steady growth over the past 20 years. A 2018 study found that 31.6% of all students are taking at least one online course (Seaman, Allen, & Seaman, 2018). But, although the growth of online courses has improved access to education, it hasn’t necessarily coincided with a growth of relevant, engaging, and innovative learning experiences. While many educators and online course designers recognize the value of project-based learning, concerns over the skills and the time required to develop authentic projects limits their use in online classes. This blog post will look at ways Constructionism, the theory that learning is most effective when students make authentic artifacts to build knowledge, can be applied to online higher education.

Constructionism is a term first defined by Seymour Papert, an MIT scholar, educational theorist, and an early champion of using computers in education (MIT Media Lab, 2016). Papert built on the earlier work of philosopher Jean Piaget. Piaget’s similarly named Constructivist theory proposed that children learn not as information is transmitted to them or in response to stimulation, but through experiences in which they are given the opportunity to “construct meaning.” While Papert agreed, he expanded on these ideas and slightly modified the name. He believed that constructing knowledge was more effective when it was done “in the world.”

Papert’s Constructionism theory held that students learned best when given an opportunity to construct their own meaning by creating meaningful artifacts for an authentic audience. He felt that by creating something to share, something that “can be shown, discussed, examined, probed, and admired” student motivation to learn was increased (Papert, 1993, p. 143).

Papert illustrated this theory working with elementary school aged children to program Legos. His work in education inspired the development of the Lego Mindstorms line, that now has widespread use in K-12 STEM educational programs and robotic competitions. Papert developed a curriculum based on his Constructionism theory for elementary school children in classrooms. But how can these same principles, those of learning by doing, be applied to adults earning college degrees online?

Creating effective online learning requires new practices. Earning an undergraduate degree in Oregon represents roughly 5400 hours of schoolwork.1 But what does that look like? For an online student, this time is spent going through the learning materials online and completing the related activities and assessments. The majority of online instructional materials are designed for passive consumption. Slide-based presentations and PDF articles are being embedded into Learning Management Systems (LMS’s), and whiteboards and lectures are being videotaped and exported to YouTube. To demonstrate their understanding of the material, students are asked to post in discussion forums and to write papers. Imagine completing 5400 hours of these types of activities to earn a degree.

Face-to-face interaction with an instructor and classmates can inspire effort that is more difficult to motivate in virtual instruction. Research findings by Constructivist thinkers have found that in order to facilitate an active learning experience for students, they must be doing something besides passively reading or listening to lecture content. “Teachers can’t “pour” knowledge into the heads of students as they might pour lemonade into a glass; rather, students make their own lemonade” (Ormrod, 2016, pp. 158–159). Students are more engaged when they are presented with the challenge of analyzing, synthesizing, evaluating, and presenting information. They retain more when they participate in their own learning.

There is now widespread availability of multimedia tools that can enable students to create content that reflects on what they are learning. These include podcasts, skits, videos, and narrated presentations. They can create timelines, online portfolios, or interactive maps. Assignments like these usually require higher order thinking skills – asking students to analyze or synthesize what they have learned and share it with an audience.

I had the opportunity to create multimodal projects several times while earning my master’s degree at Western Oregon. I created numerous digital stories. I used them to introduce myself to my online classmates, to create tutorials, and to share experiences raising my children after my husband passed away (see my first digital story, Suck it up Buttercup). In doing these projects, I realized that I had a story to tell – and one to which I needed to add my voice. They were powerful and engaging learning experiences for me. I became comfortable with the technology required to create the projects, I practiced writing, editing, speaking and presentation skills. In the process of sharing a bit of myself with my classmates and instructors I felt connected to them in a way that I had not before as a distance learner. I was proud of the projects I created. I put long hours into them and continued to edit them after they had been submitted and graded because I wanted to improve them and share them with a broader audience. I have never done this with a discussion forum post or research paper. One of my course presentations, in conjunction with an online portfolio I created for a different class, was used to interview for the job I now hold as an Instructional Designer at Oregon State University.

Technology-based assessment projects should only be introduced to curriculum intentionally. Assignments should be selected carefully to align with the learning outcomes of the course and should be appropriate for the level of the course. Projects should be challenging, but doable and relevant to the learner’s goals and outcomes developed at the beginning of course design.

While introducing Constructionism into online courses using technology-based tools may move away from traditional teaching methods, it does not mean students will not develop the same types of core skills expected from an undergraduate education. Judith V. Boettcher holds a Ph.D. in education and cognitive psychology and owns the website “Designing for Learning.” In a 2011 article on assessment alternatives to writing papers, Boettcher asserted that the skills required for written assignments: critical thinking, analysis, knowledge of the subject, assembly of ideas, and information processing were still exercised and developed when the output was a different type of product (Judith V. Boettcher, 2011). Her point is well taken.

Consider what it takes for a student to create a video documentary, script a podcast, or even develop a narrated presentation. Many of the skills required to write a research paper, essay or thoughtful discussion post are also present in assignments that leverage technology for creation. The student still has to enter the conversation about their subject area with thoughtful and well-developed contributions. But with the wealth of tools now available, there are many ways for them to share their work. Boettcher also noted that looking for ways to leverage technology in assessment strategies has the additional benefit of reducing the burden of reading “endless numbers of papers.”

Many instructors worry that learning curves associated with new tools will interfere with the ability to absorb the course content. However, when probing faculty, often it is their own unfamiliarity with technology that is at the root of this fear. It is worth experimenting before presupposing that learning how to build a website or create an animated presentation or video will be too hard.

Student portfolio on the new google sitesRecent advances in technology have produced endless collections of websites and apps that have a very low barrier to creating visually stunning multimedia content. Many of them are free or low cost, particularly to educators. As an example, the new Google Sites released in 2018 makes it easy for those with no web development experience to create and publish a website including videos, pictures, documents and audio files. Users can apply themes, chose colors and change font styles to personalize the site. As users add content to templated page layouts, they are automatically aligned and sized based on best design practices. Google Sites has the added advantage for those concerned about privacy of allowing content to be restricted to users on a school’s domain or to invited individuals.

In contrast to many university faculty instructors who are new to multimedia content creation tools, this generation of students has grown up online. They use online tools for social interactions, at work, for school, and to pursue their personal interests. Their research projects start with an online search, so much so that looking for information has become synonymous with the name of the world’s most popular internet search engine. “Let me Google that.” If a student has questions about how to use a tool to create a presentation or edit a video, they will do just that. More likely however, they will just start trying to use it, building useful, employable skills as they do so.

In 2013, Google commissioned a study that reinforced the value of employees willing to think for themselves, experiment, and explore new ways of sharing information. Writing about this study in the Washington Post, Cathy Davidson (Cathy Davidson, 2017), author of “The New Education: How to revolutionize the University to Prepare Students for a World in Flux,” said that the study showed that workplace success is predicted largely by skills such as communication, critical thinking, problem solving, curiosity and making connections across complex ideas. In the New Media Consortium 2017 Horizon Report on Higher Education they reiterated the findings of the Google study: “Real-world skills are needed to bolster employability and workplace development. Students expect to graduate into gainful employment. Institutions have a responsibility to deliver deeper, active learning experiences and skills-based training that integrate technology in meaningful ways” (Becker et al., 2017). Both of these studies reflect the importance that today’s students leave school knowing how to collaborate, question, and engage – skills not necessarily developed through passive consumption of content in online courses. In other words, a willingness to experiment, the ability to think creatively, and communication and presentation skills – all of those traits exercised when learners are asked to create and share projects demonstrating new knowledge – are those that will help them during a job search. Not only that, but some of these artifacts can be used while applying for and interviewing for work. Presentations and online portfolios can be shared with prospective employers. Prospective job applicants cannot, however, take LMS discussion posts to an interview.

Building skills and creating artifacts that will help students at work or to find work is motivating for adult learners. Adult enrollment in online degree programs is primarily driven by their career aspirations (Jordan Friedman, 2017). Numerous studies find higher student satisfaction and retention in online higher education courses when there is a link to a professional application. Student are more motivated to learn when the relevancy and applicability of activities to their chosen field is obvious (Ke, 2010). This reflects both pedagogical best practices (Luna Scott, 2015), and the fact that the majority of online students are hoping to develop skills that will support their careers. These studies  found that the ability to apply knowledge to real-world applications consistently contributed to a learner’s positive experience.

An increasing number of students are turning to online education to earn their degrees. As educational costs rise, many students are doing this out of necessity while juggling school, work, and family commitments. Educators need to look for ways to create relevant and engaging forms of assessment for these learners. There is an over-reliance on passive consumption of learning materials and text-based assignments. But students, when given the choice to develop projects of their own design and based on their own interests, are likely to retain more information and walk away with modern career skills.

The lessons Papert learned by allowing elementary school children to build and program Lego structures can and should be carried over to online higher education. Let students build something. Let them share it with an authentic audience. Leverage technology that enables students in online classes to use knowledge, rather than just store it. This type of assessment allows students to find their voice and excites them about their coursework. There are numerous options that instructors can include in an online course to foster this type of learning.

Guidelines, like those offered by the Oregon State University Registrar’s office, suggest that students should expect three hours of work per week for each credit hour (Oregon State University, 2018). Over the course of a ten-week quarterly term, like those of Oregon’s public universities, 180 credits at 12 credits a term would require 36 hours of work a week and take 15 terms, or 150 weeks. 150 weeks X 36 hours of work/per week is 5400 hours.

What is Experiential Learning?

You may have heard the terms experiential education and experiential learning. Both terms identify learning through experience as a foundational understanding. However, experiential learning is associated with individual learning.

Traditionally experience-based learning in higher education has been presented as educational opportunities complimentary to classroom instruction. These experiences might include clinical experiences, cooperative education experiences, apprenticeships, fellowships, field work, volunteerism, study abroad, practicum and internships, service learning, and student teaching experiences. These types of learning experiences are offered in and across many different disciplines (Giesen, 2012). These familiar experiential education programs demonstrate the value of individual experiential learning. But, the question remains: Is experiential learning a viable approach for online instruction?

Understanding the potential for experiential learning for online courses turns upon recognizing experiential learning as a process. The experiential learning process has been described as a cycle of learning (Kolb and Kolb, 2018). The model below illustrates The Experiential Learning Cycle.

Model of experiential learning showing sequence of Concrete Experience, Reflective Observation, Abstract Conceptualization, and Active Experimentation.

Experiential learning is understood as constructive pedagogy approach that is highly student centered. The Experience Learning Cycle begins with a concrete experience of some kind. Commonly we think of this as a real world event. That experience is followed by reflective observation of the experience, abstract conceptualization of what was learned, and the application of new learning via active experimentation. That experimentation is integrated as part of the next concrete experience.

The interactive and progressive nature of the experiential learning cycle is considered a driver of personal growth and development. The dialectics between concrete experience and abstract conceptualization as well as reflective observation and active experimentation are theorized to drive motivation for learning. 

Online Experiential Learning In Practice 

Problem-based learning, case-based learning, and  project-based learning are examples of design models that may include learning via experience in the real world (Bates, 2014). These models are often used as a way of bringing engagement into online instruction. So, if you have been incorporating these models of learning in an online course you are engaged at some level with experiential learning. But, what if you wanted to design an experiential learning assignment that does not fall within one of these models?  What might that look like?

Let’s examine the application of the experiential learning cycle to an online learning experience in a course recently offered through Ecampus at Oregon State University. The asynchronous course, Introduction to Organic Agriculture Systems, is a survey style course with an enrollment of students from Oregon and more distant.

Let’s step through The Cycle of Experiential Learning with an assignment from this course as our sample context. Hopefully it will reveal some insights into both the process of experiential learning and its practice.

1. Concrete Experience

The concrete experience for this course was an organic scavenger hunt assignment that was to be completed in the first week of the course. Although the overt activity of was a guided scavenger hunt the learning experience focus was to begin to learn systems thinking in organic agriculture. This is important to identify, as it is the authentic learning goal of the experiential learning.

As the professor framed this assignment: “This introductory activity will provide you the opportunity to explore organic availability, marketing, and farming in your community.”This concrete experience is the direct experience of organics in the student’s community.

The objectives of the scavenger hunt were to:

  • Identify organic products and marketing techniques that differentiate organic from conventional products
  • Conduct a survey of organic availability in your local store and region
  • Participate in hands-on exploration of different components of the organic system

Students were provided with a detail scavenger hunt instruction set and told to complete there first part of the assignment in a local store using an organic scavenger hunt questionnaire-work sheet. Time estimates for completion of the scavenger hunt was up to three hours at the store site. Completed work sheets were turned in to the instructor.

The key to this assignment is the real life exploration of the local organic system. Although this will be elaborated on in subsequent weeks of the course, this concrete experience will become a touchstone students can reference as they build new knowledge and skills in systems thinking in organic agriculture.

2. Reflective Observation

Part 2 of the scavenger hunt assignment includes independent student work guided by questions that ask about the presence of organic farms in the student’s area, type of organic farms, scale of the farms and evidence of their independent research work.

This element of the assignment encourages students to search for, identify, and reflect upon gaps in the local organic system in their own backyard. This work encourages students to reflect upon their own concrete experience, the quality of their work, and its linkage to understanding systems thinking.

3. Abstract Conceptualization

In week three of the course students were assigned a course discussion to share their findings from the scavenger hunt with peers. Here they compare and contrast their scavenger hunt findings and observations. In particular, students were asked to connect the social, environmental and economic dimensions of sustainability in organic agriculture to their observations taken from the scavenger hunt experience. Additionally students were asked to review other student work from different locals and explore common understandings about organic agriculture systems.

The value of this exercise from an experiential learning perspective is the application of concrete experience to more abstract concepts described by others or found in other agricultural regions. This provides opportunities for the re-conceptualizing of prior experiences with the goal of expanding on the process of organic agriculture systems thinking.

4. Active Experimentation

The Cycle of Experiential Learning rounds out with planning and applying new learning about organic agriculture systems thinking to a future concrete experience. Abstract conceptualization completed in the previous discussion will contribute to the formulation of new questions and ways of examining a local organic agriculture system. Students will likely apply these ideas to ongoing organic agriculture systems thinking in the course. In this way prior reflective observation becomes the root of new questions and predicted results for the next learning experience in organic agriculture systems thinking.
 

Final Thoughts

The final project of this course is the production of an organic systems map that explains the relationships between organic system stages (i.e., production, processing, distribution/marketing, consumption, and waste) and the dimensions of sustainability (ie. social, environmental, and economic).

In order to complete the final project students learn a great deal between their initial scavenger hunt and the final project. Their original concrete experience in systems thinking will likely inform decisions about how to re-apply new organic agriculture systems thinking.

The experiential learning assignment we just examined only works if students perceive that moving through the cycle of experiential learning addresses an authentic learning need. As the course is focused on introducing organic agriculture systems the idea of learning systems thinking makes sense. It captures the fundamental truth of what is expected to be learned (Jacobson, 2017) making the learning appropriate.

What Now?

As you explore the possibility of using experiential learning in your online course it is valuable for you to first consider formulating answers to a number of questions.

  • What is the authentic learning needed?
  • What concrete experience provides students with access to that learning? 
  • How will students carry that concrete experience through the cycle of experiential learning?
  • How will you provide the opportunity for concrete experiences for remote learners in a way that fosters individual learning and contributes to large scale learning in the course?

As you explore experiential learning for your online course revisit the model shared in this article. For help in this process contact your Ecampus instructional designer. They can help focus the key questions and suggest instructional strategies and tools to help you achieve your online experiential learning goals.

Great places to find answers to this question are the Lilly Conferences on Evidence-Based Teaching and Learning held annually at six sites from coast to coast. These conferences invite participants to engage in lively dialogue about the scholarship of teaching and learning, share best practices and hone teaching skills. Lilly Conferences are not specific to any course modality; they cover classroom, hybrid and online teaching. I found the three topics from August’s Lilly – Asheville Conference of particular interest: alternative approaches to traditional grading, faculty and student empathy, and strategies to enhance the effectiveness of lectures.

Alternative Grading Systems

Michael Palmer,  director of the University of Virginia’s Center for Teaching Excellence, challenged conference attendees to address the question “How does grading influence learning?” He then encouraged examination of alternative approaches to traditional grading practices, and explained specifications (“specs”) grading, which he personally uses. Briefly, specifications grading involves:

  • Grading assignments and assessments on a satisfactory/unsatisfactory basis, where mastery (passing) is set at a “B” level or better.
  • Bundling assignments and assessments together and allowing students to select these “bundles” based on the final course grade they are seeking. Bundles are aligned with specific course learning outcomes. Higher final grades require students to do more work and/or more challenging work.
  • Building in flexibility by giving students a few tokens at the outset that they can trade in for an extension on an assignment or an opportunity to revise/redo an unsatisfactory assignment.

Advocates of specs grading tout its effectiveness in motivating and engaging students while restoring rigor, providing actionable feedback (Palmer gives audio feedback) and supporting deep learning. To learn more, see Linda Nilson’s book Specifications Grading. Regarding ways to provide feedback that enhances learning in online courses, see Wanted: Effective Instructor Feedback.

Empathy and Student Success

Katherine Rowell of Ohio’s Sinclair Community College spoke eloquently about “The Importance of Teacher and Student Empathy in Student Success.”

  • She noted that positive faculty-student relationships are a principal factor predicting student success. In fact, the 2014 Gallup-Purdue survey found that college graduates were far more likely to be engaged in their work and thriving in key areas of well-being if they had one or more positive relationships with faculty.
  • Rowell encouraged the audience to learn more about the role that empathy plays in student success, and to look at how empathy—by both instructors and students—is manifest in the college classroom, including the online classroom.
  • She recommended Christopher Uhl and Dana Stuchul’s book Teaching as If Life Matters which encourages teachers to nurture students in ways that make learning beneficial for a more meaningful life. In this regard, OSU Business instructor Nikki Brown’s recent post in this blog on meeting students where they are is a excellent place to start.

Improving Lectures

Todd Zakrajsek of UNC-Chapel Hill presented evidence-based strategies to enhance lecture effectiveness. His message can be applied to asynchronous online learning as well as to on-campus courses:

  • Lectures and active learning are not mutually exclusive. Using lectures, including short online lectures, plus active learning can reach more learners better than using either technique in the absence of the other. Think of strategies to get learners to interact with the lecture content!
  • “We have to stop thinking there’s only one kind of lecture.” Just as there are many varieties of active learning, there are multiple kinds of lecturing!  The classic college lecture model is continuous expository lecturing, which can effectively stifle student engagement when delivered non-stop in one-hour doses! It’s useful to consider how other approaches such as case-study, discussion-framing, and problem-solving lectures can be used in online and hybrid courses.
  • We all benefit from examining the research on how learners learn, and applying this knowledge  to inform course development and teaching, including lecture design. For more on this, see The New Science of Learning, co-authored by Zakrajsek and Terry Doyle. Also consider meeting students where they are.

What are your experiences with these topics: Have you explored alternative grading systems? How do you use empathy in your teaching? What are some strategies you use to improve lecture effectiveness and incorporate active learning? Please share your ideas here.

 

Whether you are a new or seasoned online instructor, understanding how to establish and maintain instructor presence is a commonly shared challenge. What is known about online learners is they want to know their instructors are engaged and regularly interacting in the course. Students also express how important it is to know that their instructors care about them.

There is a natural distance inherent in online classrooms which necessitates purposeful actions and intentional structures to prevent isolation and to foster connection. There is great news… this distance can be overcome!  Moreover, research has indicated that instructor presence has a relationship with perceived student satisfaction and success. Being there for your students can make a difference!

Being present goes a step further beyond students perceiving that their instructors are there. By definition, instructor presence is “the design, facilitation, and direction of cognitive and social process for the purpose of realizing personally meaningful and educationally worthwhile learning outcomes.” This may sound like a significant undertaking, but rest assured that you can craft your presence over time and that you have ample support from the Ecampus team. We can help bring your ideas to life!

Keep in mind that curating instructor presence will be an evolution. Learning environments and experiences are dynamic. In addition, the composition of students will change each term, so learner needs and wants will continually shift. Strategies used within a specific context may not work for another, and that is okay.

Let’s get started!

Try starting out small by exploring different ideas. Don’t be afraid to change directions if one approach doesn’t work. With all that said, what are some strategies for establishing and maintaining presence which can be leveraged today?

Establishing presence

  • Welcome announcements
  • Instructor introduction video
  • About your instructor page
  • Course overview video
  • Virtual office hours or individualized virtual sessions to connect with students
  • Personalized language to humanize the learning experience

Maintaining presence

  • Non-graded community building spaces to connect around complex learning activities
  • Announcements to send regular updates, reminders, and check-ins
    • Tip! Announcements can also be leveraged to share and highlight valuable connections, expand upon those insights, and provide relevant resources for learners to explore.
  • Monitor learner progress
    • Regular and timely feedback which is clear and actionable
    • Outreach to learners who are struggling or engagement is lacking
  • Present content in diverse ways
    • Module overview videos
    • Audio recordings (e.g. podcast)
    • Screencast demonstrations
  • Engage in course discussions
  • Solicit student feedback
    • Tip! Consider adding a short anonymous survey in the middle of the course.

As ideas begin to percolate, please do share those with your Instructional Designer so that together you can explore different strategies and tools that will work best for you.

If you’ve ever needed an excessive amount of photographs or diagrams to accurately describe a physical object for your class, you may benefit from a 3D model.

Standard media types, including text, photographs, illustrations, audio, video, and animation, are crucial to the online learning experience. A 3D model is essentially another media type with a lot of unique qualities.

What is a 3D model?

3D Skull with annotation

3D models, in this case, are digital representations of physical objects. 3D models generally consist of a polygon mesh and a surface texture. The polygon mesh is a “shell” comprised of the different surfaces of a 3-dimensional object. There are three main components that make up this shell: vertices (points), edges (lines), and faces (planes). For what should be clear from the previous sentence, polygon meshes are often referred to as simply “geometry.” There are a lot of other technical terms associated with polygon meshes, but in practical application, you may never need to learn them.

The surface texture, at its most basic, is an image, mapped onto the surface of the polygon mesh.

A texture can be as simple as a solid color, or as complex as a high-resolution photograph. The texture will be wrapped onto the surface of the geometry with the help of a set of instructions called UVs. UVs are a complex topic in and of themselves, so it’s good enough that you just know they exist conceptually.

These textures can have physics-based properties that interact with light to produce effects such as transparency, reflection, shadows, etc.

You’re probably thinking to yourself now, that 3D models are too complicated to be of use in your courses, but that’s not necessarily true. The composition and inner workings of 3D models are complicated, for sure, but you don’t need to be an expert to benefit from them.

Where did they come from, and how are they used?

There probably isn’t a day that goes by where you don’t experience a 3D model in some way. They are everywhere.

3D models, in digital form, have been around for decades. They have been used in industrial applications extensively. 3D models are used to generate toolpaths for small and large machines to manufacture parts more consistently than a human could ever hope to. 3D models are also used to generate toolpaths for 3D printers.

3D models are used in movies, animations, and video games. Sometimes entire worlds are created with 3D models for use in virtual and augmented reality.

Modern interfaces for computers and smartphones are awash in 3D graphics. Those graphics are rendered on the screen from 3D models!

How can they help me as an educator?

If you’re still not convinced that 3D models hold any benefit to you, I’ll explain a few ways in which they can enrich your course materials.

  1. 3D models are easily examined and manipulated without damage to physical specimen.
    • If you are involved in teaching a course with physical specimens, you are no doubt familiar with the concept of a “teaching collection.” A teaching collection is a high-turnover collection that gets handled and examined during class. Normally these collections break down quickly, so instructors are hesitant to include rare and fragile specimens. Having digital proxies for these rare and fragile specimens will allow students access to otherwise unknown information. This has even bigger benefits to distance students, as they don’t have to be anywhere near the collection to examine its contents.
  2. 3D models give students unlimited time with a specimen
    • If you have a biology lab, and the students are looking at skull morphology, there’s a distinct possibility that you would have a skull on hand to examine. If there are 30 students in the course, each student will have only a short amount of time to examine the specimen. If that same skull was scanned and made into a 3D model, each student could examine it simultaneously, for as long as they need.
  3. 3D models are easily shared
    • Many schools and universities around the world are digitizing their collections and sharing them. There is a fair amount of overlap in the models being created, but the ability to add regionally exclusive content to a global repository would be an amazing benefit to science at large. Smaller schools can have access to a greater pool of materials, and that is good for everyone.
  4. 3D models have presence
    • A 3D model is a media object. That means it can be examined, but it’s special in the way that it can be interacted with. Functionality can be built on and around a 3D model. Models can be manipulated, animated, and scaled. A photograph captures the light bouncing off of an object, that is closer to a description of the object.  A 3D model is a representation of the actual physical properties of the object, and that strikes at the nature of the object itself. This means that a 3D model can “stand in” for a real object in simulations, and the laws of physics can be applied accurately. This realistic depth and spatial presence can be very impactful to students. Much more so than a simple photograph.
  5. 3D models can be analyzed
    • Because 3D models are accurate, and because they occupy no physical space, they lend themselves to analysis techniques unavailable to the physical world. Two models can be literally laid on top of one another to highlight any differences. Measurements of structures can be taken with a few clicks. In the case of a machined part, material stress tests can be run over and over without the need to replace the part.

These are only a few of the ways that an educator could leverage 3D models. There are many more. So, if you still find 3D models interesting, you’re probably wondering how to get them, or where to look. There are a lot of places to find them, and a lot of techniques to build them yourself. I’ll outline a few.

Where do I get them?

3D models are available all over the internet, but there are a few reputable sources that you should definitely try first. Some will allow you to download models, and some will allow you to link to models on their site. Some will allow you to use the models for free, while others will require a fee. Some will have options for all of the aforementioned things.

How do I create them?

The two main ways to create 3D models are scanning and modeling.

Scanning can be prohibitively expensive, as the hardware can run from a few hundred dollars, to many thousands of dollars. But, like anything else technological, you get what you pay for. The quality is substantially better with higher-end scanners.

For something a little more consumer-grade, a technique called photogrammetry can be employed. This is a software solution that only requires you to take a large series of photographs. There is some nuance to the technique, but it can work well for those unable to spend thousands of dollars on a 3D scanner. Some examples of photogrammetry software include PhotoScan and COLMAP.

Modeling has a steep learning curve. There are many different software packages that allow you to create 3D models, and depending on your application, some will be better suited than others. If you are looking to create industrial schematics or architectural models, something likeFusion 360, AutoCad, or Solidworks might be a good choice. If you’re trying to sculpt an artistic vision, where the precise dimensions are less important, Maya, Blender, Mudbox or Zbrush may be your choice.

How to use them in your class:

There are a number of ways to use 3D models in your class. The simplest way is to link to the object on the website in which it resides. At OSU Ecampus, we use the site, SketchFab, to house our 3D scans. The source files stay with us as we create them, but we can easily upload them to SketchFab, brand them, and direct students to view them. SketchFab also allows us to add data to the model by way of written descriptions andannotations anchored to specific structures in the model.

The models hosted on SketchFab behave similarly to YouTube videos. You can embed them in your own site, and they are cross-platform compatible. They are even mobile-friendly.

As you can see, there is a lot to learn about 3D models and their application. Hopefully, I’ve broken it down into some smaller pieces that you can reasonably pursue on your own. At the very least, I hope that you have a better understanding of how powerful 3D models can be.
