Abstract

Abstract: This study focuses on developing CD-ROM to implement Problem Based Learning Representation Models or MRB2M to teaching and learning of the mathematical problem solving ability in elementary school. This software was developed by R2D2 models that involved researchers as a core team, teacher, students, cameramen, and programmer as a participant team. The results were prototypes of teacher guides, student worksheets, the free and inexpensive materials, and CD-ROM for teaching and learning mathematical problem solving at the alpha and beta version level.

Abstract

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. Kata kunci: applying,encoding, inferring, mapping, kubus. Abstract: The analogical reasoning is needed to solve the mathematical problems, such as in cube problem. The study purpose to describe the analogical reasoning to solve the problem about similarity of elements and area of cubes. The research used the descriptive method that included giving the analogy test to 30 students, rreducing, classifying, and analyzing the answers, crosscheck through in-deep interviews of 3 students selected, describing the meaning of the patterns and concluding. The test of analogy was an essay of similarity of the elements and areas of cubes problems. The data were presented by bar charts, tables, and pictures. The research finding, there were two patterns of students' answers to solve the similarity of cube elements problem: (1) that there were some students master applying analogy only, (2) the other master encoding, inferring, mapping and applying analogies. There were four patterns of students' answers to solve the cubes area problem: (1) that there were students didn't master all of the analogies, but the other students masters of (2) encoding, applying, (3) encoding, inferring, mapping, and (4) encoding, inferring, mapping, applying analogies. Keywords: applying, encoding, inferring, mapping, cube.

Abstract

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.
