Abstract

The purpose of this study is to examine how students make mistakes when attempting to solve equality and inequality problems in trigonometry and algebra using the Newman method. A qualitative descriptive research methodology is employed in this study. Students enrolled in Manado State University's 2023–2024 Mathematics Education Study Program during their first semester served as the research subjects. Test and interview techniques are used in data collection. Three steps made up the data analysis in this study: reduction, data display, and data verification. Data analysis utilizing the Newman approach yielded the following conclusions: 5.6% encoding errors, 4.8% reading errors, 12% comprehension errors, 8.4% transformation errors, and 18.8% process skill errors were made when solving equation and inequality problems. The inability of pupils to comprehend the concept of the subject being explained, their lack of willingness to study, and their carelessness when reading and completing questions are the causes contributing to these blunders.

Abstract

Sehubungan dengan terbitnya Permendikbudristek No. 17 Tahun 2021 tentang Asesmen Nasional, khususnya Asesmen Kompetensi Minimum (AKM), literasi dan numerasi menjadi perbincangan dalam dunia pendidikan di Indonesia. Namun penelitian mengenai topik ini hanya berkisar pada siswa sekolah dasar dan menengah. Penelitian yang berkaitan dengan tingkat numerasi orang dewasa masih sedikit, dalam hal ini adalah guru atau mahasiswa di program studi pendidikan (mahasiswa yang sedang menjalani pelatihan menjadi guru). Penelitian ini bertujuan untuk menganalisis bagian mana dari numerasi yang menjadi kelemahan mahasiswa program studi pendidikan. Penelitian ini dilakukan dengan menggunakan pendekatan deskriptif-kualitatif. Penelitian ini melibatkan tiga mahasiswa pendidikan dari salah satu universitas di Sulawesi Utara. Data yang dikumpulkan bertujuan untuk mengetahui kemampuan berhitung mahasiswa prodi pendidikan berdasarkan kemampuannya dalam menyelesaikan soal-soal jenis AKM. Peneliti menganalisis pekerjaan tiga siswa pendidikan pada tes yang terdiri dari tiga jenis soal yang berbeda (masalah numerasi yang mirip dengan soal-soal AKM). Berdasarkan studi ini, peneliti menemukan bahwa mahasiswa prodi pendidikan yang terlibat dalam penelitian, mengalami masalah dalam memahami konsep matematika yang disajikan dalam konteks tertentu. Ketiganya masih memahami matematika sebagai mata pelajaran yang perlu dihafal rumusnya dibandingkan memahami cara pengembangan rumusnya.

Abstract

Penelitian ini bertujuan untuk mengkaji perbedaan hasil belajar siswa pada materi persamaan kuadrat antara siswa yang diajarkan menggunakan pendekatan open-ended dan yang diajarkan dengan pendekatan teacher-centered di SMA Negeri 2 Tondano. Penelitian ini menggunakan desain eksperimen kuasi dengan kelompok eksperimen dan kontrol, yang masing-masing terdiri dari 18 siswa. Instrumen yang digunakan adalah tes tertulis yang terdiri dari pretest dan posttest. Pembelajaran pada kelompok eksperimen dilakukan dengan pendekatan open-ended, yang memberi kesempatan bagi siswa untuk menemukan berbagai cara penyelesaian masalah, sedangkan kelompok kontrol menggunakan pendekatan teacher-centered. Data dikumpulkan melalui pretest dan posttest yang mengukur pemahaman siswa terhadap materi persamaan kuadrat. Hasil analisis menunjukkan bahwa terdapat perbedaan signifikan antara hasil belajar siswa yang diajarkan dengan pendekatan open-ended dan yang diajarkan dengan pendekatan teacher-centered. Rata-rata nilai posttest untuk kelompok eksperimen adalah 81,67, sementara kelompok kontrol 75,83. Uji Independent Sample T-Test menunjukkan p-value < 0,05, yang mengindikasikan adanya perbedaan yang signifikan antara kedua kelompok. Pembahasan menunjukkan bahwa pendekatan open-ended lebih efektif dalam meningkatkan kemampuan berpikir kritis dan kreatif siswa serta membantu mereka memahami konsep matematika lebih mendalam. Kesimpulannya, pendekatan open-ended terbukti lebih efektif dalam meningkatkan hasil belajar siswa pada materi persamaan kuadrat dibandingkan dengan pendekatan teacher-centered. Penelitian ini menyarankan agar guru matematika menerapkan pendekatan open-ended dalam pembelajaran untuk meningkatkan kreativitas dan pemahaman konsep siswa.

Abstract

This study aims to identify whether the learning outcomes of students who learn using the Problem Based Learning (PBL) model are higher than the learning outcomes of students who learn using the Conventional learning model on the material of Curved Side Spaces. This study used a posttest-only control group design. The population in this study were all grade IX students, with a sample consisting of grade IX A as an experimental class of 23 students and grade IX B as a control class of 23 students at SMP N 3 Tondano in the 2024/2025 school year. The results showed a difference in the learning outcomes of students taught with the Problem Based Learning (PBL) learning model compared to students taught with the Conventional learning model. Based on these results, it is concluded that learning using the Problem Based Learning (PBL) model can improve students' mathematics learning outcomes on the material of Curved Side Spaces.

Abstract

This study investigates how the school environment, both physical and non-physical, can support the development of middle school students’ numeracy in Indonesia. Conducted during the Kampus Mengajar program, the study used a mixed methods approach in two junior high schools in North Sulawesi. Environmental interventions included numeracy-themed visual displays, games, and integration of numeracy across subjects and projects. A total of 48 Grade 8 students were involved in pre- and post-tests, supported by interviews and observations. Results showed statistically significant improvements in students’ numeracy scores after the intervention. Qualitative data revealed that students engagement in classroom increased. Moreover, the interventions received positive perceptions from students, teachers, and principals. Both schools faced some challenges, such as space limitations and teachers engagement was mostly limited to those teaching science and mathematics. The findings suggest that designing a school environment, both physical and non-physical, that is numeracy-rich can enhance students' numeracy skills, even with limited resources. Further studies are recommended to explore long-term impacts and broader implementation.

Abstract

Low levels of student engagement and learning motivation have led to limited critical thinking skills, which in turn have affected students’ learning outcomes that remain below the Minimum Mastery Criteria (MMC). This study aims to determine whether students who received instruction through the Problem-Based Learning (PBL) model achieved higher mathematics learning outcomes than those taught using the conventional (lecture-based) model on the topic of Relations and Functions. This research employed a quasi-experimental method with a pretest–posttest control group design. Population consisted of eighth-grade students from SMP Negeri 3 Tondano, while the samples were class VIII-A (22 students) as the experimental group and class VIII-B (17 students) as the control group. The research instrument comprised written essay tests administered as pretests and posttests in both groups. Data were analyzed using inferential statistical procedures. Data were first tested for normality using the Liliefors test, followed by a homogeneity test (F-test). After both assumptions were met, an independent samples t-test (two-tailed) was performed to test the hypothesis. The results showed a statistically significant difference in mathematics learning outcomes between students who learned through the PBL model and those taught using the conventional lecture-based method. Therefore, it can be concluded that the implementation of the PBL model effectively enhances students’ mathematics learning outcomes on the topic of Relations and Functions, providing evidence that active, problem-oriented instruction can improve students’ conceptual understanding and achievement in mathematics.
