The purpose of this research is to know the difference of critical thinking ability between students in learning with problem solving model using LKS assisted diagram Ve with students in learning by problem solving learning using LKS without diagram Ve. This research is a quasi-experimental research with pretest-postest nonequivalent control group design. The subjects were class XI MIPA 6E3 as experimental class 1 and XI MIPA 6D3 as experimental class 2. Students in experiment 1 class were taught with problem solving using assisted LKS diagram Ve while students in experimental class 2 were solved with problem solving using LKS without Ve diagram. Instruments for measuring students' critical thinking skills are essays of validation. The results showed that the students using the assisted LKS diagram Ve in the thermochemical learning resulted in a higher N-Gain score (0.74 = high category) than the class that did not use the Ve diagram (0.69 = medium category).
