The Effectiveness of Visual Media Human Coordination System to Improve Students' Metacognition and Concept Mastery on Learning with Group Investigation Model

Abstract

This study aims to determine the effectiveness of visual media human coordination system to improve students' metacognition and concept mastery in learning with the group investigation model. The research was carried out at SMA Negeri 1 Ungaran for the academic year 2021/2022. The research method used is an experimental research method with quasi-experimental type two group pretest-posttest with control design. Sampling was done by purposive sampling. Class XI MIPA 5 as the experimental group used the visual media human coordination system in learning with the GI model and class XI MIPA 6 as the control group used video and PPT in learning with the GI model. The effectiveness of the visual media human coordination system in learning with the Group Investigation (GI) model to improve metacognition ability was determined from hypothesis testing, there was a significant difference in metacognitive ability between the experimental class and the control class. The effectiveness of the visual media human coordination system in learning with the Group Investigation (GI) model to improve students' conceptual mastery skills is determined by the criteria, 1) Achievement of KKM, 2) Obtaining N-Gain, and 3) There are significant differences in the results of students' concept mastery between the experimental class and control class. The results of the metacognitive ability hypothesis test showed that there was no significant difference in the metacognitive ability of the experimental class and the control class. The results of the concept mastery ability showed that the experimental and control class classical mastery > 75% with the increase in students' classical mastery in the experimental class which was higher than the control class. The results of the N-gain test showed that the students' mastery of concepts in the experimental class had reached the criteria. The results of the hypothesis test showed that there was a significant difference in the mastery of the concept of the experimental class and the control class. The conclusion of this study is that the visual media of the human coordination system ­in learning with the GI model is effective in increasing the ability to master concepts but is not effective in increasing students' metacognitive abilities.
