The area near the electrode surface is called the diffusion layer, and to understand electrochemistry, it is crucial that students have a knowledge of the phenomena occurring at the diffusion layer. Here, we present a demonstration and activity to visualize and analyze the expansion of a micrometer-sized diffusion layer. The electrode process…

Digital learning increasingly makes use of realistic visualizations, although realism can be demanding for learners. Color coding is a popular way of helping learners understand visualizations and has been found to aid in learning with detailed visualizations. However, previous research has shown that color coding must not always be an effective…
