PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE TEAMS GAMES TOURNAMENT (TGT) MENGGUNAKAN MEDIA AUDIO VISUAL (YOUTUBE) TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA KELAS VIII SMP NEGERI 1 MENGGALA KABUPATEN TULANG BAWANG

Abstract

The problem in this study is the lack of maximum mathematical problem solving ability of eighth grade students of SMP Negeri 1 Menggala. The purpose of this study was to analyze the average difference in students' mathematical problem solving abilities using the Teams Games Tournament (TGT) cooperative learning model using audio-visual media (Youtube) and those using conventional learning models for class VIII odd semester students of SMP Negeri 1 Menggala in the academic year. 2022/2023. This research is using experimental method. The population in this study were all students of class VIII SMP Negeri 1 Menggala, while the samples were taken as many as 2 classes, namely class VIII D as the experimental class with 32 students, and class VIII C as the control class with 32 students. Students' mathematical problem solving ability is measured by a test in the form of an essay as many as 5 questions. Hypothesis testing using t-test. From the results of hypothesis testing using statistical formulas, the value of t_hit = 3.61 is obtained. From the t distribution table at a significant level of 5%, it is obtained t_daf = 1.67. Thus, because t_hit>t_daf with a value of 3.61>1.67, the average mathematical problem-solving ability of students using the Teams Games Tournament (TGT) cooperative learning model using audio-visual media (Youtube) is higher than the average ability. solving mathematical problems of students using conventional models in class VIII odd semester SMP Negeri 1 Menggala for the academic year 2022/2023 or it can be said "There is an influence of the Teams Games Tournament (TGT) cooperative learning model using audio visual media (Youtube) on mathematical problem solving abilities VIII grade students of SMP Negeri 1 Menggala for the academic year 2022/2023”.
