Abstract

This study aims to determine whether the application of a Think Pair Share (TPS) cooperative learning model is better than using a direct learning model on the linear inequality of one variable material on the communication skills of class VII students of SMP Negeri 5 Batang Angkola T.A. 2021-2022. The population in this study were all students of SMP Negeri 5 Batang Angkola T.A 2021-2022. The sample in this study consisted of 2 classes, namely class VII-1 and class VII-2. This type of research is a quasi-experimental. In this study, the data collection tool used was a test instrument in the form of a description, each test consisting of 3 questions that had been declared valid by a team of experts and based on trials on non-sample research. From the results of the post-test data analysis of mathematical communication skills using the t-test level = 0.05, it was obtained ttable = 1.9973 and tcount = 3.389. So, it was concluded that there was an effect of the Think Pair Share (TPS) cooperative learning model on communication. students' mathematics on the material of one variable linear inequalities class VII SMP Negeri 5 Batang Angkola T.A. 2021-2022. The suggestion that researchers can give is that the Think Pair Share (TPS) cooperative learning model is suitable for use as a teaching method with efficient use of time and is suitable for linear inequalities of one variable.

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.

Abstract

The urgency of this research is due to the limited learning resources that support the development of creative thinking in mathematics, which is an essential skill in the 21st century. This research aims to develop an interactive E-LKPD based on Project Based Learning (PjBL) that is valid, practical and effective in facilitating creative mathematical thinking skills in junior high school students.. The method used is research and development (R&D) by applying the 4-D model which includes the stages of defining, designing (design), development, and dissemination. The resulting product was tested for validity by a team of material and design experts with an average score of 3.28, and its practicality and effectiveness were assessed through student and teacher responses with an average total practical score of 3.5. Evaluation of improving mathematical creative thinking abilities using PjBL-based E-LKPD shows an average score of 80.86, which is included in the very high category with a completeness level reaching 89.65%. Thus, the PjBL-based E-LKPD is suitable for use because it meets the criteria of being valid, practical and effective. The implication of this research is the need for further development of the model used to produce products that are higher quality and more effective in supporting the creative mathematical learning process.Urgensi penelitian ini dikarenakan masih terbatasnya sumber belajar yang mendukung pengembangan berpikir kreatif dalam matematika, yang merupakan keterampilan esensial di abad 21. Penelitian ini bertujuan untuk mengembangkan E-LKPD interaktif berbasis Project Based Learning (PjBL) yang valid, praktis, dan efektif dalam memfasilitasi kemampuan berpikir kreatif matematis pada siswa SMP. Metode yang digunakan adalah research and development (R&D) dengan mengaplikasikan model 4-D yang meliputi tahapan pendefinisian (define), perancangan (design), pengembangan (develop), dan penyebaran (disseminate). Produk yang dihasilkan diuji melalui validitas oleh tim ahli materi dan desain dengan skor rata-rata 3,28, serta kepraktisan dan keefektivannya yang dinilai melalui respon peserta didik dan guru dengan rata-rata total nilai praktis 3,5. Evaluasi peningkatan kemampuan berpikir kreatif matematis menggunakan E-LKPD berbasis PjBL menunjukkan skor rata-rata 80,86, yang termasuk dalam kategori sangat tinggi dengan tingkat ketuntasan mencapai 89,65%. Dengan demikian, E-LKPD berbasis PjBL layak digunakan karena telah memenuhi kriteria valid, praktis, dan efektif. Implikasi dari penelitian ini adalah perlunya pengembangan lebih lanjut pada model yang digunakan untuk menghasilkan produk yang lebih berkualitas tinggi dan efektif dalam mendukung proses pembelajaran kreatif matematis.
