You enjoy watching a good animation, right? Moving pictures are hard to resist. But how well do people learn from this format? Possibly less than you might think. When compared to static graphics, animations get mixed reviews as an effective learning medium. But don’t be discouraged. There are ways you can make animations more effective. So there is a happy ending.
Types of Animation for Learning
Any of the animation types listed below could be potentially used for instructional purposes.
- 2D Animation: Creating the illusion of motion by the rapid display of a sequence of static images or frames that minimally differ from each other.
- 3D Animation: Creating the illusion of moving objects rendered from 3D wireframes. Based on mathematical algorithms, the objects can be rotated and moved over time.
- Motion Graphics: Moving graphical elements and text across the screen. This is what we create with certain authoring and presentation tools.
- Transformations: This refers to animations that depict changes without movement, such as color transformations (a person blushing) or lines changing from thin to thick (clogged arteries maybe?).
- Stop-motion Animation: This refers to photographs of an object shown in a quick sequence to create the illusion of movement.
Reasons for Using Animation
Educational psychologist Richard Lowe (2004) writes that there are basically two main reasons for using animations for learning—affective and cognitive.
Animations will attract and capture attention because motion is one of the primary attributes of a graphic that makes viewers take notice. Animations can also increase motivation because of their novelty. When they are humorous, they create a positive affect.
One newer approach that may be of interest is the style of the animated information graphic (see an example from the Articulate community). This approach can be used for introductory explanations that may be considered boring otherwise.
Animations that have a cognitive purpose can facilitate learning because they provide more and different information than static graphics. They have the potential to help a learner build a more accurate mental model of a system’s behavior compared to graphics alone (see Schnotz & Rasch, 2005). There are many functions that animation can fulfill, such as:
- Explaining a dynamic process
- Visualizing things that can not be seen with the naked eye
- Simulating a system
- Making abstract concepts more concrete (such as with visual metaphors)
- Visualizing quantitative data
- Improving one’s spatial abilities
- Depicting hosts and agents that explain
- Telling a story
- Creating a learning game or elements in a game
- Constructing knowledge in mathematics
The Good, The Bad and The Contradictory
There are quite a few studies that compared animation for learning with static graphics for learning. In these studies, the effectiveness of animation produced mixed results and some results were even contradictory. On the down side, there were several studies that showed animation-based learning had no notable benefits compared to still graphics (Teversky et al., 2002).
On the up side, the results of a meta-analysis showed that there were notable benefits to dynamic animations (Hoeffler, & Leutner, 2007). In this meta-analysis, the types of animations that had the most substantial effect on learning were:
- Representational animations rather than animations created for affective purposes
- Animations that focused on teaching procedural-motor knowledge
- Highly realistic and video-based animations
Problems with Animations and How to Fix Them
Although animations are not ideal for all learning situations, they do have great potential. When animations are not beneficial to learning, it is due to poor design, presentation to the wrong audience, or a topic that is not suitable to be animated. That is, still graphics would be better. In the problems-solutions table below, you will find very specific problems identified in the research and possible solutions.
|THE PROBLEM||THE FIX|
|PACING. Researchers say that a key problem with the animation format is information overload. Most instructional animations are not paced for the limited capacity of working memory. During an animation, learners must quickly select the relevant information and hold that information in memory to integrate it with what comes next. This creates a high cognitive load that may hinder the resources available for learning.||Provide controls so the learner can slow down the animation to a comfortable pace. Allow users to rewind the animation.|
|SPLIT ATTENTION. When an animated sequence requires reading text and watching the animation, it splits the attention of the viewer. Because the viewer can not attend to both reading and watching movement at the same time, neither channel is attended to properly.||Use voiceover in sync with the animation rather than written text. Place labels next to the objects or process that they represent so attention will not be split.|
|DIFFICULTIES FOR NOVICES. Because many animations require the capacity for high cognitive processing, learners who are not familiar with a subject can have a more difficult time comprehending the material.||People with expert knowledge usually know where to focus their attention on task-relevant information. Novices are not as quick to determine where to focus. Complex animations, therefore, tend to be more beneficial to those with greater subject knowledge and experience. Novices may benefit more from static graphics than from animations.|
|FEWER GRAPHIC DEVICES. Certain "visuospatial" techniques of static graphics, such as cross-sections and exaggeration of important features, enhance learning and reduce information overload. There are no corresponding temporal approaches to these techniques.||If these types of graphical devices are the best choice, then replace the animation with a series of static graphics that depict the key phases of the animation.|
|NOT SURE WHERE TO LOOK. It can be hard for learners to quickly determine which parts of an animation are most relevant and which are not. In fact, some of the more dazzling elements may not be the most important but will attract the most attention.||Use visual cueing devices in animations to point out where learners should place their attention. There is some evidence that a spotlight cue (where less important areas are shaded) is effective. In another experiment, arrows were not as effective as spreading color cues overlaid on salient parts of the animation (kind of like ribbons). The color should spread synchronously with important events.|
|ILLUSION OF LEARNING. Some researchers report that students may enjoy watching animations over static graphics. This positive affect creates the illusion that the learner has acquired more knowledge or skill than assessment results show.||Use appropriate methods to determine if learning is taking place. Don't rely on self-reporting alone.|
Newer technologies make animations easier to create at a reasonable cost, making the format a viable choice for instruction. With educational researchers piecing together the data on its effectiveness for learning, a set of design principles based on evidence is emerging. It is important to consider the research before choosing to use the animation format. Then animations will be able to meet their potential for learning.
