Episode 2: An interview with Marcia C. Linn and Kihyun “Kelly” Ryoo, authors of the article titled: Designing guidance for interpreting dynamic visualizations: Generating versus reading explanations.
Dynamic computer visualizations can help students understand complex science concepts, such as photosynthesis. How can teachers help students interpret dynamic computer visualizations? We studied an interactive, dynamic visualization of energy transformation during photosynthesis. We asked half the students to read explanations while using the visualization. We asked the other half to write their own explanations about three key concepts. Both groups of students made progress in understanding how energy is involved in photosynthesis. We were surprised to discover that the students who wrote their own explanations learned more than those who read scientific explanations. Play the podcast to hear why!
