Abstract

Animation serves as a powerful tool in education, translating complex, abstract, or invisible concepts into clear, dynamic visuals. This method is highly effective in subjects like science, technology, engineering, and mathematics (STEM), where it can illustrate processes that are too fast, too slow, or too small to observe directly. For example, medical animations can show a drug’s mechanism of action at a cellular level, while physics animations can demonstrate the behavior of electromagnetic fields. This visual approach supports cognitive load theory, which suggests that by presenting information in both visual and verbal forms, learning is made more efficient, and the brain’s working memory is not overwhelmed. Educational animation transforms passive reading into an active viewing experience, which studies show can improve student engagement and knowledge retention. For animators, this field represents a growing opportunity to blend artistic skill with scientific accuracy to create content that has a direct impact on learning.

Animation in education is the use of moving images to help explain concepts and support learning. This technique is particularly useful for topics that are difficult to grasp from a static textbook image or a lecture alone. By making abstract ideas concrete and invisible processes visible, animation can simplify complex subjects.

Making the invisible visible

Many concepts in science, technology, engineering, and mathematics (STEM) involve processes that cannot be seen with the naked eye. Animation can illustrate these events.

  • In medicine, 3D medical animation is used to teach surgical procedures or show how a new drug works inside the body at a molecular level. Students can watch a heart valve function or a virus attack a cell, providing a clear visual model that text cannot match.
  • In physics, animation can demonstrate forces like gravity or electromagnetism, which are invisible. Students can see the path of a projectile or the interaction of magnetic field lines, making the mathematical formulas that describe these processes easier to understand.
  • In biology, animation can show processes that happen over very long or very short timescales. It can compress the millennia of evolution or slow down the millisecond-long firing of a neuron.

How animation supports learning

Animation is effective as a teaching tool because of how the human brain processes information. Cognitive load theory is an important concept here. It suggests that our “working memory,” the part of the brain that handles new information, has a limited capacity. If a topic is too complex, working memory can be overwhelmed, and learning stops.

Animation can help manage this cognitive load. According to research on multimedia learning, presenting information in two ways—visually (with animation) and audibly (with narration)—can be more effective than using text alone. The visual and audio information is processed in different channels of the brain, making the learning process more efficient.

However, a poorly designed animation can be counterproductive. If an animation is too fast, includes distracting sounds, or is cluttered with irrelevant information, it can increase cognitive load and confuse the learner. Effective educational animation is clear, focused, and purposeful.

Engagement and retention

Beyond its cognitive benefits, animation makes learning more engaging. Static diagrams and dense text can be intimidating. A dynamic, colorful animation can capture a student’s attention and make the content more interesting. This increased engagement is linked to better knowledge retention. A 2021 study on the use of animated videos in science learning found they were highly effective in improving student learning outcomes by helping students understand the material.

For animators entering this field, the work requires a different set of skills. It combines the core principles of animation with a need for scientific and educational accuracy. The animator must work with subject-matter experts to ensure the visual representation is correct, all while creating a visual story that is clear and engaging for a student audience.
