Implementation of asking and group competition learning strategies to improve critical thinking skill

Abstract

The aim of this research to examine physic learning strategies base of asking activities and group Competition (PLSAC) in order to improve Senior High School student’s critical thinking skills. This research was carried out by using quasi experimental method. Senior High School students at XII grade in Tasikmalaya West Java chosen as the subject of this research and two classes were taken sample at physics subject topic. This research revealed that the student which used physics learning strategy base of asking activities and group competition(PLSAC) significantly had more critical thinking skills than those that used conventional method. The average of N-gain of critical thinking skills for experiment class was 0,38 while for control class was 0,27. Teachers and students gave good comments on the implemented learning strategies. We conclude that Physic Learning Strategy base of Asking activities and group Competition (PLSAC) is better than conventional learning strategies in improving the student’s critical thinking skill.
