Abstract

The low mathematical problem-solving abilities of students are due to teacher-centered learning and a lack of independent study habits. This study aims to examine the effect of Polya's problem-solving approach on the mathematical problem-solving abilities of eighth-grade students at SMP Muhammadiyah Rambah. This research is a quasi-experimental study using the Non-Equivalent Posttest-Only Control Group Design. The population consists of all eighth-grade students at SMP Muhammadiyah Rambah. Samples were selected using random sampling, resulting in class VIII-1 as the experimental group and class VIII-2 as the control group. The experimental group used Polya's problem-solving approach, while the control group received conventional instruction. Data on mathematical problem-solving abilities were collected through tests administered at the end of the learning process, using validated instruments that measured validity, difficulty level, discrimination power, and reliability. Data analysis included hypothesis testing, preceded by a normality test. The normality test results indicated that the data were not normally distributed, so the Mann Whitney test was used for hypothesis testing. The results showed that Zcount = 4.95 > Ztable = 1.96 with α = 0.05, leading to the rejection of H0. Therefore, it can be concluded that Polya's problem-solving approach significantly affects the mathematical problem-solving abilities of eighth-grade students at SMP Muhammadiyah Rambah.

Abstract

This study aims to determine whether the Contextual Teaching and Learning (CTL) approach influences the mathematical reasoning ability of 8th-grade students at SMP Negeri 5 Ujungbatu. The research design used is a Quasi-Experiment with a Two Group Posttest Only design. The population in this study consists of the 8th-grade classes at SMP Negeri 5 Ujungbatu. Sampling was done using Random Sampling, selecting two classes as sample groups. Class VIII.1 was the experimental group, and Class VIII.3 was the control group. The instrument in this study is a test of mathematical reasoning ability given to the sample classes. The normality test, conducted using the Lilliefors test, showed that both Class VIII.1 and VIII.3 had non-normal distributions. Based on the hypothesis test using the Mann-Whitney test, the calculated value (t count) was 228, and the tabulated value (t table) was 87. This indicates that t count ≥ t tabel, leading to the rejection of the null hypothesis (H0). Therefore, it can be concluded that the Contextual Teaching and Learning (CTL) approach influences the mathematical reasoning ability of 8th-grade students at SMP Negeri 5 Ujungbatu.

Abstract

This study aims to develop a Guided Discovery-based Student Activity Sheet for seventh-grade students in junior high school, focusing on Algebraic Form material and ensuring its validity. The research follows the Research and Development method, consisting of three main stages: defining, designing, and developing. The instrument used in this study is a validation questionnaire. Based on the validity test of the Guided Discovery-based Student Activity Sheet conducted by two validators with several revisions and improvements, the average validation score obtained was 3.03, indicating a highly valid category. Thus, the Guided Discovery-based Student Activity Sheet for Algebraic Form material, intended for seventh-grade students in junior high school, is valid.

Abstract

Aljabar merupakan bagian penting dalam pembelajaran matematika yang mendukung pemahaman konsep matematika tingkat lanjut dan memiliki penerapan luas di berbagai disiplin ilmu. Salah satu tantangan terbesar yang dialami siswa dalam pembelajaran aljabar adalah menyelesaikan soal cerita. Oleh karena itu, penelitian ini dilakukan dengan tujuan untuk mengidentifikasi kesulitan dan menganalisis hambatan belajar siswa dalam menyelesaikan soal cerita aljabar. Pendekatan kualitatif dengan desain fenomenologi hermeneutik digunakan untuk mencapai tujuan tersebut. Pengumpulan data dilakukan melalui tes tertulis, wawancara, dan studi dokumen. Hasil penelitian menunjukkan bahwa siswa mengalami kesulitan: (1) memahami maksud soal dan gagal menangkap informasi penting pada soal, (2) menentukan operasi matematika yang relevan dengan informasi pada soal, (3) memahami bahwa seluruh kalimat pada soal sebagai satu kesatuan utuh, (4) mentransformasi kalimat verbal menjadi model matematika, dan (5) menyelesaikan model matematika yang telah dibuat. Berdasarkan faktor penyebabnya, kesulitan-kesulitan tersebut dikategorikan kedalam beberapa hambatan belajar (learning obstacle), yaitu ontogenic obstacle (instrumental and conceptual), didactical obstacle, dan epistemological obstacle. Temuan ini sangat berarti untuk memahami secara komprehensif hambatan belajar yang menyebabkan kesulitan siswa dalam menyelesaikan soal cerita aljabar dan dapat dijadikan landasan dalam mengembangkan desain pembelajaran terkait soal cerita aljabar. Algebra is an essential component of mathematics education, supporting a deeper understanding of advanced mathematical concepts and having broad applications across various disciplines. One of the most significant challenges students encounter in algebra learning is solving word problems. Therefore, this study was conducted with the aim of identifying students’ difficulties and analyzing the learning obstacles they encounter in solving algebraic word problems. A qualitative approach with a hermeneutic phenomenological design was employed to achieve this objective. Data collection methods included written tests, interviews, and document analysis. The findings revealed that students faced difficulties in: (1) comprehending key information and the intent of the problem, (2) determining mathematical operations relevant to the given information, (3) understanding the entire problem statement as an integrated whole, (4) transforming verbal sentences into mathematical models, and (5) solving the developed mathematical models. Based on the underlying causes, these difficulties are categorized as ontogenic obstacles (instrumental and conceptual), didactical obstacles, and epistemological obstacles. These findings are significant for providing a comprehensive understanding of the learning obstacles that contribute to students' difficulties in solving algebraic word problems. Furthermore, they serve as a foundation for developing instructional designs that specifically address algebraic word problem-solving.

Abstract

LKPD as a learning resource plays an important role for students in learning activities to be actively involved in understanding concepts. The problem is that teachers have not been motivated to make their own LKPD according to the characteristics and abilities of students. This is because teachers do not understand the importance of using LKPD which are prepared by themselves in learning and the mechanics and technicalities of compiling LKPD correctly and well. The teacher only uses textbooks and LKPD which contains a summary of the material, sample questions and practice questions without any process of finding concepts. Students receive information from LKPD without being able to explore their ability to obtain information/concept discovery independently. In connection with these problems, training and assistance in the preparation of LKPD was carried out at SMPN 3 Rambah Hilir. The teacher participated in this activity enthusiastically. This can be seen from the positive response given by dmana there were 15.4% gave a very good response and 76.9% gave a good response. The material and assistance provided in the training helped teachers make a better LKPD, namely 15.4% stated that it was very good, 69.2% stated that it was good and 15.4% stated that it was quite good. Teachers became motivated to make their own LKPD, namely there were 15.4% very good, 76.9% good and 7.7% enough.
