In September of 2015 funding from the National Science Foundation was awarded to our project - Collaborative Research: Developing a Visualization Framework for Chemical Reactions.
Interviews with 7 SJSU Instructors led to a revised model of a redox animation
Previous studies with students led to the design of one additional wrong animation that reflected features commonly portrayed in hand drawings made by students prior to viewing animations.
In the Spring of 2016, the animations were tested in a classroom setting through clicker questions to learn which of three animations students found most appealing for its connection to experimental evidence. The findings showcased in the figure above indicate that students try to fit the animation to the balanced equation.
In late March, Kelly presented findings via a poster presentation at an NSF workshop held in Washington DC.
In late May and June, Kelly gave invited oral presentations at conferences held in Goiânia, Brazil and Villa Clara, Cuba.
The project team continues to work on revision of the video of experimental redox evidence and the development of perspective videos that model possible ways to reason about the connection between evidence and atomic level. The redox segment is anticipated to be ready for website release in the Fall of 2016 and the project team has begun storyboarding the design of the precipitation segment.
A book chapter is being written based on a presentation given at Pacifichem and to portray the naturalistic study down with clickers.
