Application of the Jigsaw Learning Model to Improve Understanding of Geography Concepts at Bina Mulya Gadingrejo High School

Abstract

This study aims to increase understanding of the concept of geography in the subject of population dynamics in Indonesia for class XI IPS SMA Bina Mulya Gadingrejo using the jigsaw learning model. This research is a classroom action research (CAR) which is carried out in 2 cycles covering the stages of planning, action, observation, and reflection. This study also uses a research design in the form of one group pretest – posttest. The subjects in this study were students of class XI IPS SMA Bina Mulya Gadingrejo. Data collection techniques in research using observation, tests, and documentation. The data analysis technique used is the N-gain test (normalized gain). The results showed that there was an increase in understanding of the concept of geography in the subject of population dynamics in Indonesia in class XI IPS SMA Bina Mulya Gadingrejo. This leads to an increase in students' understanding scores, seen from the understanding scores before the action, and from the comprehension tests in cycle I and cycle II. Understanding of the pre-action, namely the criteria of very less as many as 13 students, the criteria were lacking as many as 2 students and the criteria were sufficient, good and very good did not yet exist because there were no students who got the range of values on the 3 criteria. Understanding at the stage of cycle I increased this because students who got very low criterion scores did not exist, 3 students lacked criteria, 1 student had enough criteria, 9 students good criteria and 2 students very good. At the end of cycle II there was also an increase, this was indicated by students who were included in the very less and non-existent criteria, 2 students sufficient criteria, 4 students good criteria and 9 students very good criteria. The magnitude of the increase in N-gain between pre-action and cycle I was 0.6 in the moderate category, between cycle I and cycle II, namely 0.35 in the moderate category.
