Abstract

As we know, there are still many students who still have difficulty understanding the set material. This of course affects the learning outcomes. Thereofere, a Problem Based Learning (PBL) learning method is needed into mathematics learning, with the hope that students are more familiar with and understand the concepts given to the set material. The purpose of this research is to improve the learning outcomes of mathematics on set material. This study uses a Class Action Research (CAR) model with 30 students in class VII-D SMPN 1 Margaasih. This research was conducted in three cycles, with each cycle consisting of: 1) Planning, 2) implementation, 3) observation, 4) reflection. The data analysis technique is to see the increase in learning outcomes from the three learning cycles with a limit of 85% reaching the KKM value of 75. The learning outcomes of SMP Negeri 1 Margaasih students who initially be concluded that with the Problem Based Learning (PBL) method students better understand the material and have an effect on increasing learning outcomes.

Abstract

The purpose of this research was to identify students' difficulties in answering questions about mathematical problem solving abilities (KPMM) on the material quadratic equation (PK). The method used in this research is qualitative descriptive  method. The subjects in this research were 18 students of class IX at SMPN 1 Cihampelas. The data collection technique was using a test question the KPMM with of 4 grains question. The results of this research found the level of students' ability to answer KPMM-PK questions based on the KPMM steps. The highest percentage of 74% lies in the difficulty of checking the correctness of answers with difficult criteria. While the lowest percentage of 60% lies in the difficulty of planning a settlement with quite difficult criteria. Meanwhile, when viewed from the level of student ability, the difficulties of students with high abilities have not difficult criteria, the difficulties of students who have moderate abilities are in the slightly difficult criteria, and the difficulties of students who have low abilities lie in quite difficult criteria.

Abstract

The low ability of students to solve mathematical problems is the background of this research. The aim of this research is to determine the increase in mathematical problem solving abilities of students who learn through models Problem Based Learning. The method used is the design experimental method as if experimental with shape non-equivalent control group. The subjects used were class 7D students as the experimental group and class 7J students as the control group at SMP Negeri 33 Bandung. The data collection technique uses mathematical problem solving ability test instruments using ratio and comparison material. The mathematical problem solving ability test was given twice at a time pretest and posttest. Data processing and analysis using applications Microsoft Excel 2021 and software SPSS 26. The results of the research show that the mathematical problem solving abilities of students who learn through models increase Problem Based Learning better than normal learning.

Abstract

This research was motivated by the low mathematical problem solving ability of students based on the results of field observations and the results of previous research. This study aims to determine the effectiveness of LKPD assisted by live worksheets with a problem-based learning approach to the mathematical problem solving ability of grade VIII students. The method used in this study is an experimental method with One-Group Pretest-Posttest Design by Sugiyono. The subjects in this study were 30 grade VIII students at MTs Al-Firdaus with low, medium to high categories. The research instrument used in this study was in the form of five description questions adjusted to indicators of problem-solving ability which were then calculated using the SPSS application. Based on the calculation of the comparison of pre-test and post-test values, it is found that the post-test value is greater than the pre-test value. In the pre-test students still have some errors in working on the problems given, while during the post-test few students make mistakes in solving problems. Based on the research conducted, it can be concluded that LKPD assisted by live worksheets with a problem-based learning approach is effective in improving the mathematical problem solving ability of grade VIII students, especially on the Pythagorean theorem material.

Abstract

Kemampuan Pemecahan Masalah Matematis (KPMM) adalah keterampilan esensial yang perlu dimiliki dan dikuasai siswa, terutama dalam menyelesaikan masalah sehari-hari namun realitas di lapangan menunjukkan kemampuan memecahkan masalah masih rendah. Dalam mendukung peningkatan KPMM, maka diperlukan bahan ajar yang membantu siswa untuk belajar secara aktif dan tidak menimbulkan perasaan bosan pada diri siswa ketika siswa mempelajari matematika di sekolah. Tujuan penelitian ini  mengembangkan bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra. Design Research adalah metode yang dipergunakan pada  penelitian ini. Penelitian ini terbagi menjadi dua bagian, yaitu desain perencanaan dan desain evaluasi formatif. Subjek pada penelitian adalah  38 siswa SMK  Gema Karya Bahana di Kota Bekasi Kelas X.  Alat yang digunakan dalam pengumpulan data berupa  skala sikap, wawancara, dokumentasi dan uji coba soal. Pengolahan data menggunakan cara kuantitatif dan kualitatif. Kesimpulan pada penelitian ini adalah  bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra sangat valid, praktis dan sangat efektif dalam meningkatkan KPMM terutama dalam materi Program Linear, sehingga bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra dapat dipergunakan sebagai alternatif  dalam meningkatkan KPMM siswa

Abstract

Mathematicals communication ability is one of essential mathematical abilities that every person, who learns mathematics, needs to have. However, many facts found in many studies has shown us that students’ achievements on this ability are still low. Factors that may cause it spread from teacher factors, tools, approaches, learning media to students themselves. To overcome these issues, many efforts are made to select and implement learning approaches that can improve students' mathematical communication ability as well as their activities in instructional process. Thus, the purpose of this study is to examine whether the implementation of GeoGebra-assisted discovery learning approach is effective in improving vocational school students' mathematicals communication ability or not. This quasi experimental research design involved 60 students of Gema Karya Bahana Vocational School as samples. The samples were divided into two groups in which 30 students of Accounting-1 class as the experimental group and 30 students of Accounting-2 as the control group. The data collected through a description test consisted of 3 questions on a linear program. The data collected through the test, both in pre-test and post-test, then analyzed using inferential statistics. The results of this analysis showed that the implementation of the discovery Learning approach assisted by GeoGebra was effective in improving vocational school students' mathematicals communication ability. Thus,  the discovery learning approach assisted by GeoGebra can be implemented on instructional processes as one of  instructional approach alternatives.

Abstract

This community service activity aims to enhance the competence of teachers at SMP and SMK Putra Juang in designing mathematics literacy questions aligned with the demands of the Merdeka Curriculum and the national assessment. The training was initiated due to the teachers’ limited understanding of the characteristics of mathematics literacy questions, which emphasisis on critical thinking skills, contextual problem-solving, and conceptual interconnections. The activity was implemented using a participatory approach through workshops, group discussions, and intensive mentoring. The results of the activity indicate an improvement in teachers' ability to develop questions with relevant contexts, diverse representations, and appropriate competency indicators. Furthermore, this activity had a positive impact on teachers’ preparedness for the national assessment and the implementation of literacy-based learning. Based on these findings, this article recommends the continuation of similar training programs as part of efforts to support teachers’ competence development.
