Appling, Jeffrey R.; Peake, Lisa C. – Journal of Science Education and Technology, 2004
The effect of intervening use of molecular visualization software was tested on 73 first-year general chemistry students. Pretests and posttests included both traditional multiple-choice questions and model-building activities. Overall students improved after working with the software, although students performed less well on the model-building…
