Addressing Student Misconceptions Concerning Electron Flow in Aqueous Solutions with Instruction Including Computer Animations and Conceptual Change Strategies
International Journal of Science Education Vol. 22, No. 5 (2000) pp. 521–37
Investigates the effects of both computer animations of microscopic chemical processes occurring in a galvanic cell and conceptual-change instruction based on chemical demonstrations on students' conceptions of current flow in electrolyte solutions. ...
Journal of Science Education and Technology Vol. 22, No. 2 (April 2013) pp. 103–112
In a previous study, the authors identified several student misconceptions regarding the process of dissolving ionic compounds in water. The present study used multiple-choice questions whose distractors were derived from these misconceptions to...
Student Misinterpretations and Misconceptions Based on Their Explanations of Two Computer Animations of Varying Complexity Depicting the Same Oxidation-Reduction Reaction
Chemistry Education Research and Practice Vol. 13, No. 4 (2012) pp. 471–483
A group of 55 students were shown unnarrated versions of two different particulate-level computer animations of varying complexity depicting the oxidation-reduction reaction of aqueous silver nitrate and solid copper metal. These students were asked ...

Using a Computer Animation To Improve Students' Conceptual Understanding of a Can-Crushing Demonstration
Journal of Chemical Education Vol. 77, No. 11 (2000) pp. 1517–20
Presents several student responses to viewing a can-crushing demonstration in which a soda can containing a small amount of water was heated on a hot-plate to boil the water, removed from the heat, and sealed by inverting over a container of cold...
American Biology Teacher Vol. 63, No. 2 (2001) pp. 104–9
Investigates whether viewing computer animations representing the process of diffusion and osmosis affects students' conceptions. Discusses the difficulties of implementing computer animations in the classroom. (Contains 27 references.) (YDS)
Journal of Chemical Education Vol. 84, No. 5 (May 2007)
A research study was carried out to measure the effect of a computer animation as part of the assessment of conceptual understanding of second-semester general chemistry students. The major impact of the animation was observed to be in minimizing...
