Abstract

This study aims to describe students' mathematical communication abilities in writing and orally and to find out the factors causing the low mathematical communication skills of students in one of the Palangka Raya High Schools. This research is a qualitative descriptive study. This research was conducted in the odd semester of the 2022/2023 academic year. The subjects of this study were students of class X-MIPA 4 at the school. To find out the factors causing the low ability of students' mathematical communication, 2 students were selected from each category of students' ability to be interviewed. Data collection techniques using written and oral tests and interviews. The results showed that students' mathematical communication abilities in the exponential function material in this class were moderate. Internal factors that cause low students' mathematical communication skills are: 1) Knowledge: Students cannot explain exponential functions, 2) Understanding: Lack of students' ability to understand the intent of the questions and content of the material so that students cannot solve the questions given, 3) Application: lack of students' ability to apply formulas related to exponential functions.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya pemahaman siswa dalam konsep operasi hitung bilangan kecil. Tujuan penelitian ini adalah mendeskripsikan penerapan model Pembelajaran Matematika Realistik berbantuan Blok Dienes untuk meningkatkan hasil belajar siswa kelas IV SDN 1 Paring Lahung. Penelitian ini dilaksanakan selama dua siklus. Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK). Teknik pengumpulan data menggunakan observasi, tes, dan dokumentasi. Hasil penelitian menunjukkan bahwa pada siklus I jumlah siswa yang memperoleh nilai ketuntasan minimal 70 sebanyak 1 siswa (11,1%) dan yang tidak memenuhi nilai ketuntasan minimal 70 sebanyak 8 siswa (88,8%) dengan nilai rata-rata siswa sebesar 25, 8. Pada siklus 2 mengalami peningkatan yang signifikan, jumlah siswa yang memenuhi nilai ketuntasan minimal 70 sebanyak 10 siswa (90,9%) dan yang tidak memenuhi nilai ketuntasan minimal 70 sebanyak 1 siswa (9,1%) dengan nilai rata-rata siswa sebesar 84 ,8. Hasil belajar siswa mengalami peningkatan dari siklus I ke siklus II sebesar 79,8%. Dapat disimpulkan bantuan bahwa penerapan model Pembelajaran Matematika Realistik dengan Blok Dienes dapat meningkatkan hasil belajar siswa kelas IV SDN 1 Paring Lahung pada operasi hitung bilangan kecil.

Abstract

This study aims to compare the effectiveness of the Problem Based Learning (PBL) and Discovery Learning (DL) models based on the learning outcomes of 10th-grade students at SMA Negeri 5 Palangka Raya. The research uses a quantitative approach with an experimental post-test only design. The samples used in this study were the students from classes X-2 and X-3. The data collection technique employed was a post-test to measure the students' learning outcomes. The results of the study show that (1) the Problem Based Learning (PBL) model is effective in improving the mathematics learning outcomes of students in class X-2 SMA Negeri 5 Palangka Raya, with 56% of students achieving scores above average. (2) Based on the t-test, the p-value for the DL model was found to be less than 0.05, indicating that the DL model provides a significantly better improvement in learning outcomes compared to the PBL model. The average post-test score for the class using the DL model (90.9) was higher than that of the class using the PBL model (80.28), showing a significant difference in learning outcomes
