The main purpose of this study was to enhance student understanding of the scientific concepts of chemical reaction rate. Forty-four grade 11 students were the target group. The treatment tools were seven learning plans of 5E inquiry incorporated with an analogy learning approach during 15 hours of class time. In each learning plan, the students…

This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

Many students perform extraction experiments without connecting relevant molecular features to corresponding macroscopic features. Two versions of an Organic Extraction Simulation, one with text "captions" and the other with "narration" accompanying the animation, were developed based on a cognitive view of multimedia learning.…
