Abstract

This study was conducted to obtain students' mental models after learning using multiple representations. The application of learning based on multiple representations is carried out through the interconnection between the three levels of chemical phenomenon (macro, sub-micro, and symbolic). The research samples are taken from the 2011 year of Physics Education (3 class) randomly selected from 8 available classes. The number of students from whom the samples were taken is 96 students. The students’ mental model is confirmed through the procurement of essay test questions encourage them to think at the three levels of chemical phenomenon. The results of this research show that the students’ mental models towards chemistry reaction stoichiometry was mirrored in various questions from the interpretation down to the verbal-to-symbolic transformation and verbal-to-visual transformation (sub-micro diagram) and vice versa. Findings indicated that macro–submicro– symbolic teaching by used multiple representation method could be enhancing student mental models and learning effectivity of chemical reactions. It indicates that there has been a statistically significant change on the students’ mental models after multiple representations learning method was implemented.
