High School Students’ Mental Models on Chemical Equilibrium
Abstract: Chemical equilibrium knowledge has many abstract concepts that often lead to alternative conceptions and misconceptions. One way that can be used to find out students’ conceptions is to identify their mental models.The purpose of this study was to investigate students’ mental models in und...

This study applied a survey research design. The subjects were 12thgrade high school students consisting of 181 students distributed into 5 classes.

Data analysis was performed by categorizing stu-dent’ mental models into initial, synthetic and scientific mental models. The results showed that 51.60% of respondents had a scientific mental model, 23.52% of them had a synthetic mental model, and 24.88% of others had an initial mental model. Whereas the respondents’ average score of chemical equilibrium mental models was 63.36 from a maximum score of 100. This score belongs to the good category.
