Abstract
Abstract: 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). Abstrak: Tujuan penelitian ini adalah untuk mengetahui perbedaan kemampuan berpikir kritis antara siswa yang dibelajarkan dengan model pembelajaran problem solving menggunakan LKS berbantuan diagram Ve dengan siswa yang dibelajarkan dengan pembelajaran problem solving menggunakan LKS tanpa diagram Ve. Penelitian ini merupakan penelitian eksperimen semu dengan desain pretest-postest nonequivalent control group. Subjek penelitian adalah kelas XI MIPA 6E3 sebagai kelas eksperimen 1 dan XI MIPA 6D3 sebagai kelas eksperimen 2. Siswa pada kelas eksperimen 1 dibelajarkan dengan problem solving menggunakan LKS berbantuan diagram Ve, sedangkan siswa pada kelas eksperimen 2 dibelajarkan dengan problem solving menggunakan LKS tanpa diagram Ve. Instrumen untuk mengukur kemampuan berpikir kritis siswa berupa soal esai yang tervalidasi. Hasil penelitian menunjukkan bahwa siswa yang menggunakan LKS berbantuan diagram Ve dalam pembelajaran termokimia menghasilkan peningkatan kemampuan berpikir kritis (N-Gain score) yang lebih tinggi (0.74 = kategori tinggi) daripada kelas yang tidak menggunakan diagram Ve (0.69 = kategori sedang).
