Abstract

Tujuan penelitian ini untuk mengetahui bagaimana tingkat kemampuan pemecahan masalah matematis siswa kelas VII A di Mts An-Nahl Cikeusik, Pandeglang, Banten dalam menyelesaikan soal cerita pada materi himpunan. Penelitian kualitatif dengan pendekatan deskriptif ialah jenis penelitiannya yang dipakai dalam penelitian ini. Subjek dalam penelitian ini berjumlah 6 orang siswa yang dipilih secara purposive sampling dengan tiga kategori yaitu 2 siswa dengan kemampuan tinggi, 2 siswa berkemampuan sedang, dan 2 siswa berkemampuan rendah. Instrumen yang digunakan berupa tes tertulis terdiri dari 3 soal uraian, dan wawancara mendalam . Hasil analisis data pada tingkatan kemampuan pemecahan masalahan matematis berdasarkan ketercapaian langkah Polya, siswa yang berkemampuan tinggi telah tercapai targetnya dengan sangat baik,  pada siswa yang berkemampuan sedang belum memiliki kemampuan dengan baik, dan pada siswa yang berkemampuan rendah belum mampu melaksanakan keempat langkah Polya.

Abstract

The purpose of this study was to develop teaching materials in the form of LKPD trigonometry materials through the RME approach. Research and development is carried out using the Design Based Research (DBR) method with the Plomp development model consisting of three stages, namely: Preliminary Research, Prototyping Stages and Assessment. This article is part of a research entitled "Development of Trigonometry Teaching Materials through Realistic Mathematics Education Approaches", which contains results and discussions at the preliminary research and prototyping stages (up to prototype-2). The research was conducted at MAS Mathla'ul Anwar Center. The research begins with a needs analysis in the field, then continues with the creation of LKPD. The worksheets are validated by material experts and linguists. The validation results from material experts are 91.83% with a very valid category and from linguists the validation percentage is 75% with a fairly valid category and needs minor revisions. The results of the LKPD validation by the validator show that the LKPD is feasible to be tested on students with an average percentage of 86.25% with a very valid category. The revision of the validation stage resulted in prototype-1. The small group test was carried out on students of class XI IPA 2. The small group test produced prototype-2 which was ready to be used in classroom learning.

Abstract

This research is a continuation of the article Development of Trigonometric Material Teaching Materials through the RME Approach (Meika et al., 2023). Before the teaching materials that have been developed are used, it is necessary to know in advance the effectiveness of the teaching materials. Therefore, it is necessary to trial the use of these teaching materials in a class to determine their effectiveness. The purpose of this study is to determine the effectiveness of RME-based LKPD on the ability to understand concepts in terms of learning completeness. The method used is Design Based Research (DBR) with the Plomp development model consisting of three stages, namely: Preliminary Research, Prototyping Stage and Assessment. This article contains the results of the assessment phase. At the assessment stage, a final test was carried out and filled out a student response questionnaire to determine the effectiveness of the LKPD that had been developed. The effectiveness of LKPD is seen from the completeness of student learning outcomes. The final test results showed that the average score of class X Science 1 was 78 with three students who did not complete KKM. KKM Madrasah Aliyah Mathla'ul Anwar Menes Centre is 71. The percentage of students who achieved completion was 85.72%. Therefore, LKPD products have been effective in developing students' ability to understand mathematical concepts. The results of the student response questionnaire showed that the average percentage of all aspects assessed was 77.87% with the category "Good".
