Improving student achievement in the topic of chemical energy by implementing new learning materials and strategies

In order to reduce difficulties and misconceptions in the topic of chemical energy, a new learning package was developed and implemented in Israeli high‐school classes. The implementation was based on a variety of learning activities which optimized students’ involvement in the learning process. Two experimental groups, which differed in the sequence of these learning activities, and a control group participated in the study. The results enabled us to draw conclusions about the advantages of the learning package, and about the effectiveness of the different learning activities according to students’ ability.
