摘要：The aim of this research is identify the effectiveness of a multiple representation-based learning model, which builds a mental model within the concept of atomic structure. The research sample of 108 students in 3 classes is obtained randomly from among students of Mathematics and Science Education Studies using a stratified random sampling technique. The same number of students formed the co ntrol group. In the experimental class, the learning was cond ucted by using multiple representations, whereas the control classes undertook conventional learning. Result of the research shows that (1) Learning with multiple rep resentations is more effective in constructing students' mental models in understanding the concept of atomic structure co mpared with the conventional learning; (2) Learning with multiple representations is suitable for lessons in classes where the students have low capability level to keep up with those who have a medium and high capability level. These findings indicate that lessons, which involve the macro-sub-micro-symbolic phenomena using multiple representations, may improve their mental model and effectiveness of atomic structure studies. The learning model is discussed as an alternative in class lessons in order for the students with initially lo w capability to keep up with those of medium and high capability in constructing their mental models
