INCREASING STUDENTS LEARNING OUTCOME THROUGH THE IMPLEMENTATION OF PROBLEM BASED-LEARNING MODEL ASSISTED WITH VIDEO ON THE CONCEPT OF ENVIRONMENTAL CHANGES AND PRESERVATION EFFORT Juriah1, Zulfiani21SMA Negeri 3 Tangerang Selatan, Indonesia2UIN Syarif Hidayatullah Jakarta, Indonesiazulfiani@uinjkt.ac.idAbstractThe research aims to determine the improvement of students’ biology learning outcomes in class X IPA 3 SMAN 3 Tangerang Selatan. It was conducted through the problem-based learning model assisted with video. The method was Classroom Action Research (CAR) held in two cycles. Using essay test and observation sheet, 29 students of class X IPA 3 were involved. The result showed that at the first cycle, students’ learning average was 85,31 with 93%learning completeness. Following the second cycle, both the learning average and completeness increased to 93,41 and 100% respectively. The results of the acquisition of communication skills and product making skills of the first cycle average 85,39 and the second cycle is 86,06. The average value of N-Gain in cycle I and II respectively is 0,67 and 0,79 (high category).  Students activities have also risen from 89% (cycle I) to 100% (cycle II). This concluded that problem based-learning model assisted with video enables students to enhance their learning outcomes especially on the concept of environmental changes and preservation effort.
