Abstract This study aims to find out how the influence of Jigsaw learning strategies on students' metacognition development. This study uses a quantitative method by distributing questionnaires to students in both classes, namely control and experiment. The population in this study was 56 students. From this study, it was found that the use of the Jigsaw type learning model in MA could provide an increase in students' metacognition. This is indicated by the average number of students' metacognition in the treatment class is higher than in the control class, namely 7,643 for the treatment group and 6,286 for the control group. The treatment class is smaller than the control class if the standard deviation is the benchmark, with 0.1174 for the treatment class and 0.1442 for the control class, which means that the jigsaw type cooperative learning model has an effect on improving students' metacognition. . Keywords cooperative learning, jigsaw, metacognition. Abstrak Penelitian ini bertujuan untuk mencari tahu bagaimana pengaruh strategi belajar Jigsaw pada perkembangan metakogni Murid.

Abstract

Abstract The achievement of high school graduates' competence is continuously improved by the government in Indonesia, one of which is by implementing the Minimum Competence Assessment. The main problem in its application is the limitations of similar problem models provided in classroom learning so that students are not accustomed to solving them. The purpose of this research is to produce mathematical reasoning questions using the Minimum Competence Assessment model for junior high school students that are valid, reliable, and have a potential impact. This research is development research with two stages of developing Tessmer’s model, namely: (1) Preliminary and (2) formative evaluation stage, which consists of self-evaluation, prototyping (expert reviews and small group), and field tests. The trial subjects of this study were 25 students of class VIII Bengkulu state junior high school 7 in Bengkulu City. The results of the study obtained questions that met valid criteria with an Aiken index each of which was more than 0.5. The questions meet reliable criteria with a count of more than 0.6 and are in the high category. The questions have a potential impact with sufficient students' selection abilities on average and students giving a good response of more than 50.00 percent. The suggestion from the research is that the teacher encourages choosing a real context to present the problem in mathematics learning.   Keywords development research, instrument test, mathematical reasoning, minimum competence assessment. Abstrak Capaian kompetensi lulusan sekolah menengah terus ditingkatkan oleh pemerintah di Indonesia, salah satunya dengan menerapkan Asesmen Kompentensi Minimum (AKM). Permasalahan utama dalam penerapannya adalah keterbatasan model soal serupa yang disediakan dalam pembelajaran di kelas sehingga siswa tidak terbiasa menyelesaikannya. Tujuan dari penelitian ini adalah untuk menghasilkan soal matematika penalaran model AKM untuk siswa SMP yang valid, reliabel, dan memiliki dampak potensial. Penelitian ini merupakan penelitian pengembangan dengan dua tahap pengembangan model Tessmer, yaitu: (1) Preliminary, dan (2) tahap formative evaluation yang terdiri dari: self-evaluation, prototyping (expert reviews dan small group) serta field test. Subjek uji coba penelitian ini adalah siswa kelas VIII SMP Negeri 7 Kota Bengkulu sebanyak 25 orang. Hasil penelitian diperoleh dua paket soal yang memenuhi kriteria valid dengan indeks Aiken masing-masing lebih dari 0,5. Soal memenuhi kriteria reliabel dengan rhitung lebih dari 0,6 dan kategori tinggi. Soal memiliki dampak pontesial yang dengan kriteria kemampuan siswa secara rata-rata cukup dan siswa memberikan respon baik lebih dari 50,00 persen. Saran dari penelitian adalah guru hendaknya memilih konteks nyata untuk menyajikan masalah dalam soal.   Kata kunci penelitian pengembangan, instrument tes, penalaran matematis, asesmen kompetensi minimum. DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1515-1526
