<![CDATA[AbstarctThe purpose of this study was to determine the effect of concept attainment approach with conceptual change text on molecular shape materials toward the learning outcomes of students SMAN 1 Sungai Pinyuh. Research form was a quasi-experimental research design with non equivalent control group pretest-postest design. The sampling method used purposive sampling, where the X MIPA 2 class was chosen as an experimental class and the X MIPA 3 class as the control class. Data collection’s tool used the achievement test in the form of an short answer. Test result by U-Mann Whitney (=0,05) obtained significant 0,000, indicating that there was a difference between the learning outcomes of student who were tought using a concept attainment approach with conceptual change text and students be taught by conventional methode in the molecular shape materials. Concept attainment approach with conceptual change text gave a high influence with effect size value by 1,48. Therefore concept attainment approach with conceptual change text influence students learning outcomes by 56.78%. Keyword: Concept Attainment Approach, Conceptual Change Text, Learning Outcomes]]>
