Abstract

One of the abilities that must be possessed and mastered by a student in the 21st century is problem solving ability. Mathematical skills are expected to be able to meet the needs of students today and in the future. The purpose of this study was to describe the results of student problem solving analysis based on the SOLO Taxonomy. This study used a qualitative descriptive approach to analyze the data. Based on the results of data analysis, it was found that students with different SOLO levels had differences and similarities at each stage of problem solving. At the stage of understanding the problem, the three subjects can identify what is known and what is asked in the problem, only the extended abstract subject adds to make a mathematical model on what is known. At the stage of planning the completion of the three subjects, they were able to mention several concepts, principles and procedures on the problem to solve the problem. At the stage of implementing the plan, the three subjects had already completed the questions based on the plans that had been made, but in the multistructural subject the answers given were not appropriate/relevant to what was asked for in the questions. At the re-examination stage, the three subjects re-examined by re-checking the formula, re-examining the work and recalculation of the results, but only the extended abstract subject could provide several different solutions.

Abstract

This research is an experimental study that aims to determine the difference in learning outcomes between students who are taught using the STAD cooperative learning model and those who are taught using the Jigsaw cooperative learning model. The population in this study was all students in class XI SMK Negeri 2 Jayapura for the academic year 2021–2022, totaling 111 people. The sample was taken using a purposive sampling technique, totaling 51 people, consisting of two classes, namely class XI, Office 3, and Class XI, Office 4. Class XI Office 3 (experimental class) is a class that is taught using the STAD cooperative learning model, and Class XI Office 4 (control class) is a class that is taught using the Jigsaw cooperative learning model. The obtained data were then analyzed using parametric statistics via a t-test. The results showed that: 1) there was no significant difference in mathematics learning outcomes between students taught by the STAD type of cooperative learning model and students who were taught by the Jigsaw type of cooperative learning model; 2) the mean of mathematics learning outcomes of students who are taught the STAD type of cooperative learning model is lower than that of students who are taught the JIGSAW type of cooperative learning model, which is 62.61 smaller than 70.43.Keywords: Cooperative model, Blended learning, Statistics

Abstract

This study aims to describe independent mathematics learning during the COVID-19 pandemic among eighth-grade students at SMP Negeri 2 Langke Rembong. The research was motivated by a lack of student learning independence in online learning, as evidenced by low motivation and interest, which resulted in passive participation in virtual classes. This study employs a descriptive quantitative approach using a survey method. The population consists of all eighth-grade students at SMP Negeri 2 Langke Rembong, totaling 339 students. The sampling technique used was probability sampling with a simple random sampling method, resulting in a sample size of 77 students. The data collection instrument was a Likert-scale questionnaire distributed to students, measuring their mathematics learning independence during the COVID-19 pandemic. The collected data was analyzed using descriptive statistical analysis. The results indicate that eighth-grade students at SMP Negeri 2 Langke Rembong demonstrated a high level of learning independence in mathematics during online learning. Students exhibited strong independence in eight key indicators, including formulating learning objectives, selecting learning strategies, taking the initiative to learn with or without assistance, evaluating their own learning progress, constructing meaning, collaborating with others, diagnosing learning needs, selecting and utilizing resources, and exercising self-control.

Abstract

Penelitian ini dilatar belakangi rendahnya hasil belajar matematika siswa. Salah satu upaya yang dapat dilakukan peneliti akan membandingakan model pembelajaran yang lebih cocok dalam materi mean, medan, dan modus. Tujuan penelitian ini adalah untuk mengetahui perbedaan hasil belajar siswa yang diajarkan dengan model pembelajaran Jigsaw dan STAD. Penelitian ini menggunakan pendekatan kuantitatif dan jenis penelitian eksperimen dengan menggunakan desain penelitian post-test only control design. Populasi pada penelitian ini yaitu seluruh peserta didik kelas XI SMKS YPKP TIK Kabupaten Jayapura, kemudian penentuan sampel menggunakan teknik sampel total. Instrumen dalam penelitian ini menggunakan instrumen tes dengan bentuk pilihan ganda. Pada tahap menganalisis data penelitian, digunakan uji prasyarat terlebih dahulu yang meliputi uji normalitas, uji homogenitas, dan uji n-gain. Hasil pengujian hipotesis menunjukkan bahwa; 1) Terdapat perbedaan yang signifikan antara hasil belajar kelas yang diajarkan dengan model pembelajaran Jigsaw dan kelas yang diajarkan dengan model STAD dengan nilai signifikan sebesar 0,000 < 0,05. Maka sebagian dasar pengambilan keputusan dalam uji independen sample t-test dapat disimpulkan bahwa ditolak dan diterima. 2) Besar perbedaan hasil belajar kelas yang diajarkan dengan model Jigsaw dan kelas STAD dapat dilihat dari rata-rata hasil belajar dengan nilai kelas Jigsaw 61,20 dan kelas STAD 73,80 yang artinya besar perbedaan hasil belajar antara model pembelajaran Jigsaw dan STAD sebesar 12,6%.
