Improvement of Learning Process and Learning Outcomes in Physics Learning by using Collaborative Learning Model of Group Investigation at High School (grade X, SMAN 14 Jakarta)
The aim of this research is to improve the quality of physics learning through application of collaborative learning of group investigation at grade X MIPA 2 SMAN 14 Jakarta. The method used in this research is classroom action research. This research consisted of three cycles was conducted from April to May in 2014. Each cycle consists of planning, acting, observing and reflecting. Researcher discussed and coordinated with three observers before acting step. The instruments of the research are based on observation form, assessment sheet, and students worksheet. The result of this research in learning quality aspects – student-sudent interaction, teacher-student interaction, and learning outcome, are about 75%. According to the result, we can conclude that the application of collaborative learning model of group investigation can improve learning process and learning outcomes in physics learning.
