This study aimed at investigating the effect of using Molecular Representation Strategy on developing the visual thinking second level students of high school in Chemical. The sample consisted of two groups: experimental group (n=30) which taught by using Molecular Representation Strategy, and control group (n=30) which taught by traditional method. To achieve the purpose of the study, the researcher designed teaching material in accordance with Molecular Representation Strategy, and a test to measure the visual thinking. The results showed that there are statistically significant differences among males means in the two groups on the visual thinking test in favor of the experimental group. [ABSTRACT FROM AUTHOR]
