Problem-based learning is characterized by the existence of a real problem as the context wherein students learn critical thinking skills, problem-solving, and knowledge acquisition. The concept of critical thinking gains popularity to help students obtain the ability to conduct fact analysis, support opinion with an argument, and problem-solving. The majority of Indonesian vocational school students, however, have difficulty in developing critical thinking skills and problem-solving. This research was purportedly designed to evaluate the differences of students' critical thinking ability in response to the application of various problem-based learning model namely Fishbone diagram, problem-based learning model, and expository learning model. A quasi-experimental design was applied to assess students' critical thinking. The findings indicate that there was a significant difference in students' critical thinking ability responding to the learning models. In summary, the research proposes the problem-based learning as an alternative learning model to improve student’s critical thinking ability.

Based on observations when apprenticed at SMAN 7 Pontianak it was known that students' critical thinking skills are still low. Therefore, a variety of learning models are needed to improve students' critical thinking skills. The purpose of this research was to determine the differences and effective learning model in improving students' critical thinking skills between students taught using the project-based learning model and the problem based learning model. The research method used was a quasi-experiment with a nonequivalent control group design. The data collection techniques used were measurement. The results showed a significant value of the T-test was 0.000<0.05. This means that there are differences in students' critical thinking skills taught using the project-based learning model and problem-based learning. The average value of N-Gain in the project-based learning model was 0.69 (moderate) while the problem-based learning model was 0.58 (moderate), so the project-based learning model is more effective than the problem based learning model on students' critical thinking skills.Keywords: Critical thinking skills, problem-based learning, project-based learning, cell material
