Abstract

This research aims to determine the increase in student learning activities with Team Games Tournament (TGT) type cooperative learning at MTs YPKS Padangsidimpuan. This type of research is classroom action research. The object of this research is to increase student learning activities through TGT type cooperative learning in class VIII MTs YPKS Padangsidimpuan. The research subjects were 33 students in class VIII-4. /friend's explanation was 18%, the activity of reading student books/LKS was 2.5%, the activity of noting the explanation of the teacher/friend/from the book was 12%. , distribution activities by 16%, and activities that are not relevant to learning by 51%. So it was found that student activities for each activity category had not yet reached the ideal activity criteria. The results of the analysis after being given action II were from the results of observing the activity of listening/paying attention to the teacher/friend's explanation by 46%, the activity of reading student books/LKS by 7.5%, the activity of noting the teacher/friend's explanation/from the book by 10.5%, the activity division was 19%, and activities that were not relevant to learning were 17%. This shows that student activities for the four activity categories have experienced improvement, but have met the ideal activity criteria

Abstract

This type of research is Classroom ActionResearch (CAR) by taking research subjects from Class X TKJ SMKS Al-Hasanah Sibuhuan. It consists of 20 students, 10 male students and 10 female students. The object taken in this study is to increase students' mathematics learning creativity in implementing classroom learning, which specializes in contextual learning strategies, as well as the teacher's role in classroom management. This Classroom Action Research (CAR) was carried out in two cycles which were equipped with Learning Implementation Plans (RPP), Teacher Handbooks (BPG), Student Worksheets (LKS), and test instruments including tests of students' critical thinking skills, student activity observation sheets, as well as teacher performance observation sheets managing learning. Before the instrument was used, it was tested first and obtained from the 10 tests tested there were 10 valid tests, 5 tests for cycle I and 5 tests for cycle II. The calculation shows that the test reliability coefficient is 0.84 for cycle I and 0.89 for cycle II and is stated learning creativity abilities in the first cycle obtained 65% of the minimum criteria sufficient, and for the second cycle 90%. The results of observations of student activity 79.58% of the criteria in the first cycle, increased to 88.33% in the second cycle. From the data analysis, it shows that the implementation of the actions taken has improved the teacher's ability to manage learning, from "Good enough" in cycle I to "Good" in cycle II.
