Abstract

The purpose of this research was to intimidated LMM (Leaners Mental Model) of work and energy. The mental model can be used to considered more extremely apparatus of misconceptions. The research method is an occasion study with mixed methods. The samples are 30 tenth grade students (14 boys and 16 girls, their ages were middling 16 years-old) at one of senior high school in Bandung.

The data investigation was approved purchasable in two stages. In the first stage the analysis leaners level of understanding and in the second stage the analysis leaners model of understanding. The result illustrations that mental models have been identified in the three categories, that are, 1) Scientific 26,7%, 2) Synthetic 16%, 3) Initial 57,3%. In conclusion, mental model of the initial category is higher than other categories.
