Efektifitas Penggunaan Model Pembelajaran Kooperatif Tipe Two Stay Two Stray Terhadap Kemampuan Pemecahan Masalah Matematika Siswa

Lynni Suryani Harahap — 2025-02-02

This type of research is quasi-experimental research. The sample in this study was class VII (A and B) at Panusunan Achir Hasibuan Private MTs, totaling 40 students. This research aims to determine the effectiveness of using the Two Stay Two Stray Cooperative learning model on Mathematical Problem Solving Ability in the Spss Statistics 22 program with a significance level of 5% and n=20 which is then compared against the r table to obtain a value of 0.444. rcount > rtable, namely (0.56 > 0.444) for the pretest and (0.528 > 0.444) for the posttest. The pretest results mean the experimental class and control class were 60.95 and 61.8 respectively. For the posttest results, the average score for the experimental class was 91.90 and the control class was 79.95. The pretest and posttest normality tests for the experimental class and control class have a sig > 0.05 and the homogeneity test has a sig > 0.05, so the experimental class and control class have homogeneous data conditions. For hypothesis testing, a significant value of 0.000 <0.05 was obtained. For the N-gain Score test, the experimental class obtained an average value of 79.55% and the control class obtained an average value of 45.5%.

Meningkatkan Hasil Belajar Matematika Dengan Penerapan Model Pembelajaran Inquiri Learning Dengan Bantuan LKS Di Ponpes Al-Yusufiah

Nur Atika Lubis — 2025-02-02

This research aims to determine the direct influence of the Inquiry Learning learning model to improve Mathematics learning outcomes for class VII Al-Yusufiah Huta Holbung Islamic Boarding School. The research method used is classroom action research using two cycles carried out in the second semester with material about lines and angles. The population in this study was 29 class VII students at the Al-Yusufiah Huta Holbung Islamic Boarding School. The class used as a sample is class VII-I of the Al-Yusufiah Huta Holbung Islamic Boarding School which will use the Inquiry Learning method assisted by student worksheets (LKS) in learning. The ability of students' learning outcomes in mathematics learning in class VII-I of the Al-Yusufiah Huta Holbung Islamic Boarding School on lines and angles in the first cycle increased by 55% with the "sufficient" category, then in the second cycle it increased to 86.21% with the "good" category. ”. The increase in teacher and student observation results on line and angle material in cycle I averaged 71.5% (adequate) observation results. the results of the second cycle of observations were 77.5% (Good).

Pengaruh Metode Kooperatif Learning Tipe Snowball Throwing Terhadap Kemampuan Komunikasi Matematika Siswa SMP Negeri 5 Padangsidimpuan

Wulan Eka Putri Siregar — 2025-02-02

This study aims to see whether or not there is an effect of snowball throwing type cooperative learning method on mathematical communication skills of seventh grade students of SMP Negeri 5 Padangsidimpuan. This type of research is a pseudo experiment. The research samples were VII-5 and VII-8 classes totaling 40 students. The data collection technique used is an essay-shaped test of 5 questions that have been tested with pretest and posttest reliability using the Cronbach's alpha formula in the spss application with a significant level of 5% and n = 20 which is then compared to the r table obtained a value of 0.444. It turns out that rcount> rtabel is (0.608>0.444) for the pretest and (0.556>0.444) for the posttest. Data analysis using normality test, homogeneity test and hypothesis testing. The pretest results of the average value of the experimental and control classes were 63.8 and 64.05, respectively. For the posttest results, the average value of the experimental class was 82.75 and the control class was 75.65. The normality test of the pretest and posttest of the experimental and control classes has sig>0.05 and the homogeneity test of the significant value is above 0.05 or sig>0.05, so the experimental class and control class have homogeneous data conditions. For the hypothesis test, a significant value of 0.039 or 0.039 <0.05 was obtained. Thus the researcher concluded that there was an effect of the snowball throwing type cooperative learning method on the mathematical communication skills of SMP Negeri 5 Padangsidimpuan.

Analisis Kemampuan Pemahaman Konsep Matematika Kelas VII SMP Negeri 7 Padangsidimpuan Melalui Pemanfaatan Media Audio Visual Pada Materi Bilangan Bulat

Nurhaida — 2025-02-02

This study aims to determine students' conceptual understanding after using audio-visual media on the topic of integer operations, using five indicators of mathematical conceptual understanding in Class VII 3 at SMP N 7 Padangsidimpuan. This research is qualitative in nature. The data in this study were obtained from direct observations, interviews with teachers, and interviews with students. After the data were collected, they were analyzed using three stages: data reduction, data presentation, and verification or conclusion drawing. Data validity was checked using data source triangulation. The subjects of this study were two Class VII teachers and 26 students from Class VII 3. The results of this study show that after learning using audio-visual media, some students experienced an improvement in their conceptual understanding. This improvement was observed across all indicators of conceptual understanding. Most students demonstrated a good understanding of integer operations, although a small number of students still struggled with this concept.
