The purpose of this research is to improve the critical thinking skills of class X high school students by using the Problem Based Learning model accompanied by Socioscientific Issuess. This research is a classroom action research which has 4 stages, including planning, action, observation and also reflection. The subjects of this study were 34 students of class X SMA Negeri in Sukoharjo. Data on critical thinking skills was taken at the end of each cycle. Data collection techniques in this study used observation, tests/assessment techniques, and documentation. The data analysis technique in this study is to use comparative descriptive.

These results indicate an increase in students' critical thinking skills has increased from cycle I to cycle III by 50%. So it can be concluded that the application of the Problem Based Learning model with Socioscientific Issuess can improve students' critical thinking skills.
