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.

Abstract

This study aims to determine the effect of gamification in mathematics learning on the academic achievement of seventh-grade students at SMP Negeri 5 Padangsidimpuan. The research employed a quasi-experimental method with a non-equivalent control group design. The sample consisted of two classes: an experimental group that received gamified instruction and a control group that was taught using conventional methods. Data were collected through learning outcome tests, and the analysis was conducted using parametric statistics, specifically the independent samples t-test. The analysis revealed that the average learning outcome in the experimental group was 83.6, which was higher than that of the control group, which had an average score of 76.2. The prerequisite tests indicated that the data were normally distributed and homogeneous. The t-test produced a significance value of p = 0.003 < 0.05, indicating a statistically significant difference between the two groups. The conclusion of this study is that gamified learning has a positive impact on students' mathematics achievement. Gamification enhances student engagement, motivation, and conceptual understanding. Therefore, this strategy is recommended as an innovative approach to mathematics instruction at the junior high school level.

Abstract

This research is classroom action research (PTK). The learning tools used in this research are the Learning Implementation Plan (RPP), Student Activity Sheet (LAS), test instruments, student activity observation sheets and teacher ability observation sheets to manage learning. The results of the research showed that by applying the Reciprocal Teaching learning model in cycle I, the percentage of completeness in the minimum "sufficient" category was 73.08% and in cycle II it was 84.62%. There was an increase from cycle I to cycle II of 11.54%. With achievement indicators ≥ 80% have been achieved. Then, for the results of observations of student activities in cycle I, it was found that the level of student activity was 71.05% "fair" in cycle II 80.69% "good". The increase that occurred from cycle I to cycle II was 9.64%, the achievement indicator was ≥ 80%. Meanwhile, the results of observations of the teacher's ability to manage learning in cycle I and cycle II were obtained in the "good" category.

Abstract

This study aims to examine the effect of cognitive conflict strategies on the mathematical representation ability of tenth-grade students at SMK Negeri 1 Siabu. The cognitive conflict strategy is believed to stimulate students’ active engagement through the stages of presenting conflict, creating conflict through demonstrations, and resolving it through discussion and reflection. The research employed a quasi-experimental method with a posttest-only control group design. The instruments used were a mathematical representation test and a student response questionnaire. The results showed a significant difference in mathematical representation ability between students who were taught using the cognitive conflict strategy and those who learned through conventional models. Thus, the cognitive conflict strategy is effective in improving students’ mathematical representation ability.

Abstract

This study aims to determine the effectiveness of the Jigsaw cooperative learning model in improving students' mathematics learning outcomes on polynomial material in class XI MIA 1 at SMA Negeri 1 Angkola Timur. The background of this study is the low learning outcomes of students, as indicated by average scores that have not reached the Minimum Passing Criteria (KKM). This research used the Classroom Action Research (CAR) method, which was carried out in two cycles, each consisting of the planning, implementation, observation, and reflection stages. The research subjects were 23 students with instruments in the form of learning outcome tests and student activity observation sheets. The results showed an increase in both the mastery of learning outcomes and student activity. In cycle I, the percentage of student learning mastery was only 57%, then increased in cycle II to 82.61%. Student learning activities also increased from 65.70% in cycle I to 85.53% in cycle II. Thus, it can be concluded that the application of the Jigsaw learning model is effective in improving student mathematics learning outcomes.
