Williamson, Vickie M.; Abraham, Michael R. – Journal of Research in Science Teaching, 1995
A Particulate Nature of Matter Evaluation Tests was used to explore the effect of computer animations depicting the particulate nature of matter on (n=400) college students' mental models and comprehension of chemical phenomena. Treatment groups received significantly higher conceptual understanding scores than did the control group. (30…
