The classroom samples in this study included 89 engineering students who took chemistry courses during the academic year. The results indicated that: (a) students acquired a better understanding of targeted chemistry concepts during integrated multimedia representations, (b) students’ average performance on the pretests and posttests through our chemistry course indicated a 10-point grade growth, and (c) all variants under constructivist instructions, such as F-ratio, p-values, and Cohen’s effect sizes of attitudes toward chemistry and learning chemistry were detected in terms of students’ gender, major, use of computer-based multimedia, and disposition toward computerization. A factual and systematic assessment was made in this study to incorporate computer-based multimedia teachings utilizing constructivist design principles to facilitate students’ chemistry understanding and learning attitude.
