Student's mental models in this study was built through model-based learning with multiple representations. The samples in this study was conducted through random cluster sampling with the study subjects were taken from a high school student in Lampung Province. The selected number of samples as many as two classes of students grade 10 and students involved in this study as 76 peoples. Mental models of the students was measured through tests in the form of an essay. This test is a test of creative problem solving to look at the ability of the student's imagination. The results showed that (1) After learning by using multiple representations strategy, mental models abilities of students becomes higher, which is located at the level of intermediate-3; (2) Multiple representation strategies give a high influence to the improvement of the students' mental models to the concept of atomic structure. These findings indicate that learning by multiple representations strategy could been alternative strategy in the teaching of chemistry to solve problems creatively, particularly concepts related to the phenomenon of sub-microscopic, macroscopic and symbolic.
