Abstract

In optimizing a learning process, teachers should use appropriate learning methods to achieve learning objectives. Teachers should use the experimental method because students will be given the opportunity to experience it firsthand so that students can think critically to solve a problem. The aim of this reseach is to find out the critical thinking skills of fifth grade students at SDN 2 Marikangen in learning natural science material about changes in the shape of objects through the experimental method. This study used Classroom Action Research (CAR) from Kemmis and Mc model. Taggart. The research instrument used observation and tests. Data analysis in this study uses quantitative data analysis and qualitative data analysis. Based on the results of the research, the pre-cycle data obtained, 23% or 7 students who could think critically, increased in cycle I to 61% or 19 students who could think critically, and in cycle II it increased again to 94% or 29 students who can think critically. In addition, student learning outcomes have also increased. So, it can be concluded that the application of the experimental method to learning natural science material changes in the form of objects is proven to improve students' critical thinking skills at SDN 2 Marikangen. So that this research can be said to be successful.
