Abstract

The concept of air-having pressure needs to be understood by students so that they can understand natural phenomena related to the air concept. The characteristic of the abstract concept of air having pressure leads students to misconceptions. The purpose of this study is to analyze changes in students' conceptions of the air-having pressure concept by using the POE strategy. The research method used was a pre-experiment with one group pretest-posttest design. Pretest and posttest questions were given to students using the five-level diagnostic test instrument with a total of three questions. The ability to predict-test and the ability to observe-test were performed with four questions on each test. The participants of this study consisted of 31 fifth grade students in the even semester. The categorization of conception change is divided into five patterns: construction, revision, static, disorientation, and complementation. Based on the analysis, revision had the highest percentage followed by construction. The conclusion is that the POE strategy can help students in understanding the concept of air-having pressure so that there was a change from misconception to understanding scientific concepts.

Abstract

This study aims to improve student learning outcomes on chemistry subjects by applying the Teams Games Tournament (TGT) learning model for tenth-grade students. The method used is classroom action research that is carried out in three cycles, each cycle consisting of two meetings. Techniques of data collecting use the observation sheet and final testing cycle. Observation sheet was used to determine the activity of students and the test to determine student learning outcomes. Based on research, gained mastery learning outcomes of students increased from 45% before treatment (T0) to 55% in the first cycle (T1), 72.5% in the second cycle (T2) and 87.5% in the third cycle. Average student activity within the group at the first cycle of 53.43%, 57.18% for the second cycle and the third cycle of 64.47%. Average student learning outcomes at the first cycle of 70, 55, 72,125 for the second cycle and the third cycle of 74,6. Cooperative learning strategies are effective when the curricular knowledge taught in the school is drawn from all groups by playing. Based on these results, the researchers suggest to teachers who have the same problem in learning can apply learning model Teams Games Tournament (TGT).
