MENINGKATAN AKTIVITAS BELAJAR DAN HASIL BELAJAR SISWA MELALUI METODE PROBLEM BASED LEARNING(PBL) MODEL KOOPERATIF DI KELAS XII IPA-6 SMA NEGERI 1 LUBUK SIKAPING

Abstract

The aim of this research is to improve learning activities and student learning outcomes through the method of Problem Based Learning (PBL) cooperative model in the application of the concept of redox and electrochemical reactions in class XII IPA 6 SMAN 1 LubukSikaping the academic year 2016/2017. This research was conducted by two cycles in class XII IPA-6 with the number of students 34 people. The learning process was observed in the form of activities and student learning outcomes by using observation sheet and test results. Student activity was observed using the observation sheet with five indicators. The observation of learning outcomes utilized four items description in one cycle and multiple choices as much as 25 points in the two cycle. Based on the observation of data observer towards the students’ activities in the learning process,student activity on one siklus was obtained 52.3% dramatically increasing to 75.5 % in two cycle. The resultof learning was obtained by classical completeness value of 61.3% in first cycle to 90% in second cycle.The observation of student activity has exceeded the criteria above 75% and the study has shown 90% of students who were completed with classical. The aforementioned evidences reveal that the PBL method can increase the activity of students in the learning of redox reaction and can improve student learning outcomes classical completeness.
