Pengaruh Penerapan Model Pembelajaran Berbasis Masalah Terhadap Kemampuan Berpikir Kritis Mahasiswa Calon Guru Pada Materi Fisika Kuantum

The research has been carried out on the effect of the application of problem-based learning models on the critical thinking of prospective teacher students on quantum physics material. This study aims to analysis the effect of problem-based learning models and students' critical thinking. Quantum physics material includes five sub-topics of Schrodinger's Equation, Physical Operators, Commutator, Heisenberg's Equation of Motion, and Harmonious Oscillator. This type of research is an experiment using posttest research design only group design. The population in this study were all physics education students for the 2018/2019 academic year. Sampling used total sampling technique with VIA semester students as the experimental class and VIB semester students as the control class. The research hypothesis was analysis with polled variance t-test. Based on the results of hypothesis testing for critical thinking, it is obtained t count (5.805)> t table (1.687) at the 5% significance level, it can be concluded that there was an effect of problem-based learning models on the critical thinking skills of prospective teacher students on student quantum physics material.
