Indigenous people of Dayak tribe in Kalimantan, Indonesia have traditionally relied on a system of mutual cooperation called handep. The cultural context has an influence on students mathematics learning. The handep system might be suitable for modern learning situations to develop mathematical problem-solving skill. The objective of the study was to investigate the effect of handep cooperative learning model compared to problem-based learning model on mathematical problem-solving skill of rational exponent material. The research was conducted through pretest-posttest non-equivalent control group design. The sample of 66 students was selected from the population of 304 students through cluster random sampling. The mathematical problem-solving skill assessed with essay test of the open-ended question had reliability coefficient of 0,71. The students' answers scorings were obtained with the rubric of mathematical problem-solving skill. Data analysis is conducted through ANACOVA. The result presents that the mathematical problem-solving skill of students who learned through handep cooperative learning model is better than problem-based learning. Handep cooperative learning model is suitable to enhance the mathematical problem solving skill of students in Kalimantan-Indonesia cultural context. The teacher should construct the instructional material use metacognition questioning strategy and also be familiar to their students' prior knowledge of mathematics.

Penalaran analogi diperlukan dalam memecahkan masalah matematika, seperti pada materi kubus. Tujuan penelitian ini mendeskripsikan penalaran analogi yang terbentuk dalam pemecahan masalah kesamaan unsur-unsur dan luas kubus. Metode penelitian penelitian deskriptif digunakan dengan tahap-tahap kegiatan memberikan tes analogi pada 30 siswa, mereduksi, mengelompokkan jawaban, dan menganalisis jawaban, crosscheck melalui wawancara mendalam terhadap 3 siswa cuplikan, pemaknaan dan penyimpulan. Tes analogi berbentuk tes esai kesamaan unsur-unsur dan luas kubus. Data penelitian disajikan dengan diagram batang, tabel, dan gambar. Temuan penelitian, terdapat dua pola jawaban siswa memecahkan masalah kesamaan unsur-unsur kubus: (1) siswa menguasai analogi applying dan (2) analogi encoding, inferring, mapping, applying. Ada empat pola jawaban siswa yang ditemukan dalam memecahkan masalah kesamaan luas kubus: (1) siswa yang tidak menguasai semua penalaran analogi; dan yang lainnya menguasai analogi (2) encoding dan applying; (3) encoding, inferring, dan mapping; dan (4) encoding, inferring, mapping, applying.

This article describes the development of handep cooperative learning model consist of 3-4 members become pair handep cooperative learning model in the form of module and validated by experts and students who used it. The model of development used R2D2, that focused on the design and development stage. The draft of the model at the single-path prototype level validated by the learning expert and small group validation in context the of mathematics learning in secondary school, to get the model at alpha version level. The instrument is rubric and questionnaire for small group testing. The result of the research (1) the model has fulflled the principle of quantum teaching that is context orchestrations include an exciting learning atmosphere and solid foundation; (2) junior high school students rated the model interesting and fun; (3) learning steps that to be challenging on individual work steps and mutually assisting in solved the difcult problems for students individually; (4) the model has reached the alpha version level. Abstrak Artikel ini menjelaskan pengembangan model pembelajaran kooperatif handep beranggotakan 3-4 orang menjadi model kooperatif handep berpasangan dalam bentuk modul dan dinilai oleh pakar dan siswa yang menggunakannya. Model pengembangan yang digunakan adalah R2D2 (Recursive, Reflective, Design and Development), difokuskan pada tahap design and development. Draf model pada level single path prototype divalidasi oleh pakar pembelajaran dan uji kelompok kecil dalam pembelajaran matematika di SMP, untuk mendapatkan model pada level alpha version. Instrumen berupa koesioner dengan pertanyaan terbuka untuk validasi ahli, dan angket respon siswa untuk uji kelompok kecil. Hasil penelitian (1) model telah memenuhi kaidah Quantum teaching yaitu orkestrasi konteks meliputi suasana belajar yang menggairahkan dan landasan yang kokoh, (2) siswa SMP menilai model tersebut menarik dan menyenangkan, (3) langkah-langkah pembelajaran yang dirasakan menantang pada langkah bekerja secara individual dan saling membantu secara bergiliran dalam memecahkan masalah sulit bagi siswa secara individual, dan (4) model telah mencapai level alpha version. Keywords: Aplha version; cooperative learning; pairs handep; quantum teaching; single path prototype  

This program aims to provide knowledge and skills for students who are writing a thesis at the Mathematics Education Study Program, FKIP University of Palangka Raya. The achievement target is that students are able to write scientific articles on research results in their thesis. Partners and the target audiences are 16 students who are writing a thesis at the Mathematics Education Study Program, FKIP University of Palangka Raya. Technical guidance will be held for 3 days from 08–11 October 2021 online using the Google Meet platform. Activities carried out during the stages of socialization, technical guidance, clinical guidance, and evaluation of manuscripts. The evaluation of the manuscript uses the assessment sheet for the relevant scientific journal articles, and the scientific journal accreditation guide (Arjuna). The results of providing technical guidance are as follows. Of the 16 articles, there are 4 articles whose findings are adequate and contribute to the development of science and technology. There are 6 draft articles that have been made by students, which consist of 3 draft articles with all the sub-chapters written by students waiting for the final exam schedule. Almost all draft articles have not met an adequate number of references for a scientific journal article. While the other three are draft articles that have met the requirements to be submitted for publication in scientific journals.
