Critical Thinking Ability Based on Science Process Skills With Numbered Head Together

The focus of the problem in this study is to improve students' critical thinking skills and analysis of critical thinking skills in terms of science process skills. The purpose of this study is 1) to describe the improvement of critical thinking skills; 2) describe science process skills; 3) describe critical thinking skills in terms of science process skills. The design of this study uses quantitative. The sample of this study was the fifth grade students of Kangkung 1 Elementary School and Kangkung 3 Elementary School. The data collection was done by test, observation, interview and documentation methods. The results showed that critical thinking skills at the average of the pretest scores were 52 and posttest was 62. Science process skills had a strong relationship with critical thinking skills. Students with high science process skills have critical thinking skills tend to be high or moderate, students with science process skills are having two tendencies of critical thinking skills which are moderate or low, but in this study there were no students with low science process skills. Hopefully this research will be a useful source of further research related to science process skills and critical thinking skills at the elementary school level.
