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.

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.

Active Learning: What Does the Research Show?

We often hear about new approaches in teaching, and some can take on near-mythical status. That might be the case for active learning. It’s been widely touted as the “most effective” pedagogical approach, but unless you have time to dig through the research, it may not be easy to determine if this trend is applicable – or beneficial – to your teaching and discipline.

So what does the research say about active learning? This article provides a brief summary of research results for active learning applied in STEM subjects.

Why Use Active Learning?

Before we discuss why active learning is beneficial, let’s clarify exactly what active learning is. As opposed to passive learning, such as listening to a traditional lecture, active learning requires students to do something and think about what they are doing (Bonwell & Eison, 1991).

Much research supports the power and benefits of active learning. Students have better retention and understanding when they are actively involved in the learning process (Chickering & Gamson, 1987). Active engagement promotes higher order thinking, since it often requires students to evaluate, synthesize, and analyze information. Research indicates that students develop strong connections, apply concepts to authentic scenarios, and dive deeply into the content, often discovering an unexpected level of engagement that is exciting and stimulating (Nelson, 2002).

Does Active Learning Produce Better Outcomes in STEM?

Research indicates the answer is “yes!” In an introductory physics course, Harvard professor Eric Mazur (2009) found that his students were not able to answer fundamental physics scenarios or grasp basic concepts from traditional lectures. As a result, he stopped lecturing and has become an outspoken champion for active learning.

An organic chemistry class adopted active learning, resulting in significantly higher grades for students in the active classroom than in the control group, with the greatest effect coming from low-achieving students (Cormier and Voisard, 2018). In an introductory undergraduate physics course, two large student groups were compared. The active learning section showed greater attendance, more engagement, and more than double the achievement on an exam (Deslauriers, Schelew and Weiman, 2011).

In 2004, a skeptical Michael Prince (2004) researched the then-current literature on active learning to determine whether it offered consideration for engineering. He found that many active learning recommendations directly conflicted with historical engineering teaching practices. Methods like breaking lectures into small, topic-specific segments, interspersing lecture with discussion, using problem-based scenarios, or grouping students for collaborative learning were uncommon. Ultimately, Prince reluctantly concluded that the bulk of research evidence indicated that these types of teaching methods might foster better retention and enhance critical thinking.

What About Non-STEM Classes?

Although these findings are from research in STEM disciplines, active learning contributes to better grades, more engagement, increased student satisfaction and better retention in any topic (Allen-Ramdial & Campbell, 2014). Active learning tends to increase involvement for all students, not just those already motivated to learn. Peer-to-peer collaboration helps students solve problems and better understand more complex content (Vaughan et al., 2014). Research indicates that students learn more when they actively participate in their education and are asked to think about and apply their learning (Chickering & Gamson, 1987).

Try It Yourself!

The articles cited in this post offer a number of easy-to-implement active learning suggestions that are effective in ether a face-to-face or online classroom. Give one or two a try and see if your students are more engaged in the learning  process.

  • Offer opportunities for students to practice and examine concepts with peers, such as through debates.
  • Break lectures into small, granular topics and intersperse with questions or problem-solving activities based on real-world applications. Video technologies can easily accommodate this approach for online learning.
  • Structure quizzes or other activities to give immediate feedback. Answer keys and auto-graded assessments are available as a feature in virtually any learning management system.
  • Consider “flipping” the classroom by asking students to read or watch lecture videos before in-person class sessions.
  • Design activities that encourage students to work in small groups or collaborate with others.
  • Add a personal reflection component to help students uncover new ideas or insights.

Although no single definitive study has yet been published to unequivocally prove the efficacy of active learning, the body of evidence from many studies forms a compelling argument that it is does offer significant benefits (Weimer, 2012). Give it a try and see how active learning works in your discipline.

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.
