The Effect of PjBL Model based on Skill Approach Process to Physics Critical Thinking Ability of High School Student

Abstract

This study was aimed at describing and determining the level of critical thinking skills of students using learning tools with a project based learning model based on material process skills approach to momentum and impulse in class X.4 (Modeling) and X.2 (Implementation) SMAN 1 Kalasang, Indonesia. This research was a Pre-Experiment Design research using the One-Shot Case Study Design research design. Research subjects were 48 students which obtained based on purposive sampling by looking at certain criteria and reasons. The results of the research data were obtained through critical thinking ability test instruments, learning device planning instruments, student worksheet instruments, and valid product assessment instruments, and instrument validation. Data collection techniques consisted of the preparation stage, implementation phase, and data collection stage. Data analysis techniques used were descriptive analysis and inferential analysis. The results showed that students’ critical thinking skills using learning tools with a project based learning model based on material process skills approach to the momentum and impulse of SMAN 1 Kalasang were in the good category (Modeling class with an average value of 75.20 and an Implementation class with an average value of 77.39). And there was increase in critical thinking skills after using learning tools with a project based learning model based on the process skills approach to material momentum and impulse of SMAN 1 Kalasang in the Modeling class as well as in the Implementation class.
