The research results show that after the use of the AfL instrument in project-based physics learning, students' critical thinking skills improved. This is evident from the results of the average pretest and posttest score difference test using the Paired Sample T-Test, which showed a significance value of < 0.05. The improvement in critical thinking skills is supported by the calculation of N-Gain, which falls within the moderate criteria
