Abstract. Problem based learning is an educational approach which used problem as a contex
for learning in order to develop multidiciplinary skill including critical thinking. However, 
limited research has been conducted regarding the impact of problem based learning on student’s 
critical thinking skills in class. This research is a developmental research (R&D) using ADDIE 
model that aims to develop student’s critical thinking skills through the implementation of 
student activity sheets that use problem based learning approach. The subject of this study were 
2
nd
year students of science and mathematics programe in SMA Negeri 2 Sleman. Using pre-
experimental with pretest-posttest design, the data were analyzed descriptively using N-gain 
indicator and analyzed parametrically using T-related sample test. Student’s critical thinking 
skills were observed by observer and analyzed descriptively using percentage comparison. The 
study found that the problem based learning approach has signficant impact in improving 
student’s critical thinking skills. Student’s critical thinking skills in terms of analyzing, 
interpreting, evaluating, and concluding were increased. These criteria indicated that problem-
based learning approach effective to develop student’s critical thinking skills.
