2D vs. 3D Visuals: An Analysis of Their Impact on Learning Effectiveness
Min Jung Kwon 
Hello, I am BCBA Park Hye-ji.
Today, I'd like to introduce a study on the effect of learning material format on memory and comprehension.
We encounter information in various ways in our daily lives. Especially in educational settings, visual information plays a crucial role in enhancing learners' comprehension and maximizing learning outcomes. Visual aids include not only text but also images, animations, and videos. So, which form of visual aid is most effective for learners?
In this study, we analyzed the differences between 2D static visuals and 3D animated visuals on learners' information retention capacity .
Research Purpose and Methods
The study involved 100 high school students between the ages of 16 and 20. Participants were divided into two groups (control and experimental), each of which was taught different types of visual materials.
- Learning topic: Digestive and respiratory systems in human physiology
- Control group: Learning using static visuals (photos, illustrations, line drawings, 2D graphics, photographs)
- Experimental group: Learning using animated visuals (3D graphics, videos, animations)
Each group learned the same content using different visual aids, and then compared their learning effects through questionnaires and tests.
Research Results and Analysis
According to the research results, 73.3% of students in the control group (using static visual materials) responded that the learning materials were useful, but at the same time, there were many negative feedbacks such as 'boring', 'needs explanation', and 'colors are not interesting'.
On the other hand, 87.6% of students in the experimental group (using animated visual aids) responded that the learning materials were ‘easier to understand and more memorable’, and in particular, the positive responses such as ‘fun’, ‘vivid’, and ‘intuitive to understand’ were overwhelming.
These results suggest that 3D animations and videos effectively capture learners' attention and help convey complex concepts more clearly. Furthermore, they suggest that dynamic visuals may be more effective than static visuals in enhancing learner comprehension and long-term retention .
Conclusion and Implications
This study demonstrates that the format of visual aids in educational settings plays a crucial role in maximizing learning effectiveness. In particular, using dynamic visual aids, such as 3D animations, to explain complex concepts or processes can significantly enhance learner comprehension and retention.
This provides important implications for how we leverage visuals in digital learning content creation and educational interventions.
- It is necessary to actively utilize 3D animation and dynamic content rather than simple static images.
The colors and design elements of visual aids reduce learners' cognitive burden and enhance their focus, making intuitive and visually clear content design crucial. Especially when explaining complex concepts, utilizing interactive visuals can increase learner engagement and enhance the learning experience.

With the recent rise of online education platforms and digital teaching materials, the use of animation and 3D graphics is no longer optional but essential. However, rather than simply following these trends, it's important to understand and select the visual aids that enhance learners' comprehension and maximize learning effectiveness.
To make learning more effective and enjoyable for our children, it would be a good idea to use appropriate animation materials smartly!
