Abstract

Masalah utama dalam penelitian ini yaitu Apakah Model Pembelajaran Active learning Tipe Quiz Team dapat meningkatkan hasil belajar siswa pada materi Bentuk Aljabar. Subjek penelitian adalah siswa SMP Negeri 9 Padangsidimpuan kelas VII Semester Ganjil TA.2023/2024 yang berjumlah 24 siswa, yang menjadi objek dalam penelitian ini adalah penerapan model Active Learning Tipe Quiz Team pada pokok bahasan bentuk Aljabar. Jenis penelitian ini adalah penelitian tindakan kelas ( PTK). Berdasarkan hasil penelitian sebelum diberikan tindakan pengajaran dengan metode Active Learning Tipe Quiz Team nilai rata-rata tes awal siswa adalah 32,19dengan tingkat ketuntasan belajar 4,16% dan belum mencapai tingkat ketuntasan belajar, maka diberikan tindakan pada siklus I. Setelah pemberian tindakan pengajaran melalui metode Active Learning Tipe Quiz Team pada siklus I nili rata-rata tes hasil belajar I adalah 74,16 dengan tingkat ketuntasan belajar 54,16%. Karena pada siklus I belum mencapai tingkat ketuntasan belajar maka dilanjutkan paa siklus II, pada siklus II ini kesalahan yang ada pada siklus I diperbaiki.. Sehingga nilai rata-rata yang diperoleh siswa pada siklus II ini memperoleh peningkatan. Pada tes hasil belajar II nilai rata-rata hasil belajar siswa adalah 82,5 dengan tingkat ketuntasan belajar 87,5% sehingga mengalami peningkatan rata-rata hasil belajar sebesar 8,34 dan peningkatan ketuntasan belajar klasikal sebesar33,34%.

Abstract

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%.

Abstract

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.
