Abstract

This research was  motivated by the low mathematical communication skills and lack of students' self-confidence in learning mathematics. One alternative learning that can be applied to improve students' mathematical communication skills is the Make a Match cooperative learning model. The purpose of this study was  determine self-confidence and improve mathematical communication skills of junior high school students. The research method used in this study was a quasi-experimental method with Nonequivalent Pretest-posttest Control Group Design. This research was conducted at a junior high school in Bandung Regency. The research sample was students of class VII-B as the experimental class and class VII-C as the control class. The experimental class uses the make a match type cooperative model, while the control class uses the discovery learning model. The instrument used was a test of mathematical communication skills, a confidence questionnaire and an observation sheet of educator learning activities. The results of the study were analyzed using t-test. Based on the results of the analysis, it can be concluded that the self-confidence of the two classes had a very good interpretation. Meanwhile, mathematical communication skills of students whose learning using the make a match type cooperative model was better than mathematical communication skills of students whose learning uses discovery learning models.

Abstract

The background of this research on the rectangular study is learning obstacle (LO) experienced by learners. Instructional design based on the LO experienced learners is one alternative to reduce of learning obstacle. This research aims (1) identified LO on rectangular study, (2) develop of the didactical design based on LO and relevant learning theories, (3) describe the didactical design after implementation. This research used didactical design research and qualitative approach. Data collection techniques used triangulation techniques. Research conducted at SMP Al-Qona’ah Baleendah with the subjects 38 learners class of VIII-B and 36 learners class of VII-A. The first step in the research is the analysis of the situation by conducting a test didactical diagnostic tests and interview semi-structure to identify learning obstacle experienced by learners. The second step devised a didactical design based LO and reinforced by relevant learning theories. The result of the design implementation are analyzed based on the metapedadidaktik analysis and retrosfektif analysis. The results concluded that: (1) There are four types of rectangular LO, (2) the didactical design is based on the identified LO of the learners, (3) the result of the implementation showed that didactical design can reduce LO experienced learners.

Abstract

Penelitian ini dilakukan untuk mengatasi permasalahan rendahnya berpikir kritis dan kepercayaan diri siswa. Kajian ini bertujuan untuk menentukan peningkatan kemampuan berpikir kritis matematika dan self-efficacy. Problem-Based Learning (PBL) diterapkan sebagai solusi membantu siswa dalam pembelajaran matematika memahami konten, menganalisis konsep, merencanakan strategi perhitungan, dan menyimpulkan dengan tepat dalam memecahkan masalah. Jenis pendekatan yang digunakan dalam penelitian ini adalah kuantitatif dengan metode quasi-eksperimental dan desain penelitian Nonequivalent (Pretest dan Posttest) Control-Group Design. Subjek dalam penelitian ini adalah siswa kelas VII SMPN 1 Tegalwaru, Kota Purwakarta pada tahun akademik 2022/2023. Kelas VII B sebagai kelas eksperimen dan kelas VII E sebagai kelas kontrol. Instrumen yang digunakan dalam penelitian ini adalah tes deskripsi untuk mengukur hasil belajar dan kuesioner untuk mengukur self-efficacy siswa. Teknik analisis data dalam penelitian ini menggunakan analisis kuantitatif berupa uji statistik.  Hasil yang diperoleh dari penelitian ini yaitu Kemampuan berpikir kritis peserta didik melalui model pembelajaran Problem-based learning (PBL) meningkat, sehingga berpotensi mampu mengatasi rendahnya beripir kritis siswa.
