Abstract

The aims of this study is to: 1) describe of using inside outside circle learning model, 2) describe students’ mathematic communication ability before and after using inside outside circle learning model, and 3) describe effectiveness of using inside outside circle learning model on students’ mathematic communication ability at the seventh grade students SMP Negeri 1 Tantom Angkola. This research was conducted by applying experimental method (one group pretest post test design) with sample 30 students and they were taken by using simple random sampling technique. Observation and test were used in collecting the data. Based on descriptive analysis, it was found that: (a) the score of using inside outside circle learning model was 3.9 (very good category), b) the average of students’ mathematic communication ability before using inside outside circle learning model was 33.13 (fair category) and after using inside outside circle learning model was 84.40 (very good category), significant value was 0.00<0.05, and c) N-Gain value was 0.76 (high category), inside outside circle learning model was effective which had percentage 66.7% (effective criteria). It was concluded inside outside circle learning model increased students’ mathematic communication ability at the seventh grade students SMP Negeri 1 Tantom Angkola.

Abstract

Tujuan penelitian ini adalah untuk mendeskripsikan keefektifan penggunaan model pembelajaran VAK terhadap kemampuan komunikasi matematis siswa pada topik bangun ruang pada siswa kelas delapan di SMP Negeri 8 Padangsidimpuan. Penelitian ini dilakukan dengan menerapkan eksperimen (one group pre test post test design) dengan sampel 25 siswa dan diambil dengan menggunakan teknik random sampling dari 271 siswa. Observasi dan tes digunakan dalam mengumpulkan data. Berdasarkan analisis deskriptif, ditemukan: (a) rata-rata menggunakan model pembelajaran VAK adalah 3,8 (kategori sangat baik) dan b) rata-rata kemampuan komunikasi matematis siswa pada topik bangun ruang sebelum menggunakan model pembelajaran VAK adalah 37,6 ( kategori buruk) dan setelah menggunakan model pembelajaran VAK adalah 80,5 (kategori sangat baik). Selanjutnya, dengan menggunakan formulasi N-Gain hasil menunjukkan G = 0,68 (efektif menengah), itu berarti menggunakan model pembelajaran VAK efektif pada kemampuan komunikasi matematis siswa pada bangun ruang pada siswa kelas delapan SMP Negeri 8 Padangsidimpuan. Kata kunci: VAK, kemampuan komunikasi, figur solid

Abstract

Research on cooperative learning strategies has been widely conducted; however, studies that specifically examine the effectiveness of the Think-Pair-Share strategy in teaching quadratic equations in senior high school mathematics remain limited. This study aims to analyze the effect of the effectiveness of the Think-Pair-Share instructional strategy on mathematics learning outcomes for the topic of quadratic equations among Grade X students at SMA Negeri 5 Padangsidimpuan. The research employed a quantitative approach with a correlational design, involving a sample of 102 students selected through simple random sampling. Data were collected using a questionnaire to measure the implementation of the Think-Pair-Share strategy and a multiple-choice objective test to measure mathematics learning outcomes. Data analysis was conducted descriptively and inferentially using normality tests, Pearson Product Moment correlation, and t-tests at a 5% significance level. The results show that the implementation of the Think-Pair-Share strategy was in the “good” to “very good” category, while students’ mathematics learning outcomes were in the “fair” to “good” category. Inferential analysis indicates a significant relationship between the Think-Pair-Share learning strategy and mathematics learning outcomes on quadratic equations. These findings reinforce cooperative learning theory, which emphasizes student activity and interaction, and confirm that the Think-Pair-Share strategy is effective for improving mathematics learning outcomes on quadratic equations at the senior high school level.

Abstract

Mathematics learning, particularly on the topic of Systems of Linear Equations in Two Variables (SPLDV), still faces challenges in improving students’ understanding, so learning innovations are needed that are capable of integrating technology with collaborative activities. This study aims to evaluate the effectiveness of an e-module based on the Numbered Head Together (NHT) cooperative learning model in improving students’ understanding of SPLDV material. This study used a quantitative approach with a quasi-experimental design, involving 60 students from two junior secondary school classes selected through purposive sampling. Data were collected through pre-test and post-test instruments as well as questionnaires to assess students’ responses, and were then analyzed using descriptive statistics and the t-test. The results showed that the experimental group using the NHT-based e-module experienced a 32% increase in post-test scores, higher than the control group, which experienced a 15% increase. These findings contribute to the development of technology-based cooperative learning and expand understanding of the implementation of e-modules in mathematics learning. The conclusion of this study emphasizes the importance of collaboration among students in improving mathematical understanding, and shows that the use of an NHT-based e-module can serve as a strategic alternative in learning SPLDV. The implications of this study include a theoretical contribution to the literature on technology-based learning and practical implications for curriculum development and teacher training.
