Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan koin bermuatan terhadap kepercayaan diri siswa kelas VII SMP Negeri 2 Adimulyo pada operasi bilangan bulat. Penelitian ini menggunakan metode penelitian Quasi Experiment dengan postrespons-only control design. Populasi pada penelitian ini adalah seluruh siswa kelas VII SMP Negeri 2 Adimulyo dengan sampel penelitian berjumlah 64 siswa yang terdiri dari 32 siswa kelas VII G dan 32 siswa kelas VII H. Data tersebut dianalisis menggunakan uji Mann-Whitney. Berdasarkan hasil analisis data diperoleh nilai signifikansi 0,0000195 < 0,05 sehingga H1 diterima. Dengan kata lain, terdapat pengaruh yang signifikan penggunaan koin bermuatan terhadap kepercayaan diri siswa pada operasi bilangan bulat.

Abstract

This study aims to describe the errors of prospective teacher students in making math test instruments based on cognitive levels from the Bloom’s Taxonomy Revised (BTR). BTR consists of LOTS (C1-C3) and HOTS (C4-C6) levels. This research included descriptive qualitative research. The subjects of this study were 19 prospective teacher students, namely the mathematics education department in the Mathematics Learning Evaluation course. Based on the results of the study, it was obtained that prospective teacher students made mistakes at both levels but more at the HOTS level. At the LOTS level, it is on the error level C3; at the HOTS level, it is spread at all levels, namely C4-C6. An indication of error that often arises is that prospective teacher students cannot compile questions according to their level of cognition. The questions made are often still below the level they should be. The level of the questions made is still below the level that it should be.

Abstract

Kemampuan siswa SMP dalam memahami konsep geometri masih tergolong rendah. Hal ini harus segera diatasi dikarenakan geometri memiliki kedudukan penting untuk diajarkan di sekolah mengingat bahwa konsep geometri sering dimanfaatkan dalam berbagai aspek kehidupan. Tujuan penelitian ini adalah untuk menganalisis kesalahan siswa dalam menyelesaikan soal lingkaran yang merupakan salah satu materi dalam konsep geometri. Penelitian ini menggunakan metode kualitatif yang melibatkan 30 siswa kelas 8 di salah satu SMP kota Bandung. Triangulasi dalam pengumpulan data meliputi (1) pemberian instrumen tes kemampuan pemahaman matematis siswa terkait materi lingkaran, dan (2) instrumen non tes yang meliputi pedoman observasi dan wawancara siswa, serta studi dokumen. Berdasarkan hasil temuan dan pembahasan pada penelitian ini, diperoleh informasi bahwa dalam menyelesaikan soal lingkaran, kesalahan siswa teridentifikasi dalam 2 bentuk kesalahan dari 3 kesalahan yang dapat dikategorikan melalui tahapan Kastolan yaitu kesalahan konseptual yang meliputi kesalahan dalam menentukan definisi juring, kesalahan dalam menentukan rumus panjang busur lingkaran, dan lain-lain; serta kesalahan prosedural yang meliputi kesalahan yang diakibatkan karena tidak teraturnya langkah-langkah pengerjaan soal, dan kesalahan yang diakibatkan karena ketidaktelitian siswa memahami soal dan dalam melakukan perhitungan.

Abstract

In addition to the theory and implementation, the description of research trends and the direction of development of mathematical mindset research still needs to be explored. The study aims to find trends and mapping from the mathematical mindset research development. The method used is bibliometric with the help of MS Excel and VosViewer. The metadata is 995 articles indexed by Google Scholar from 2019 to 2025, obtained from Publish or Perish by entering the keyword "mathematical mindset." The results show a sharp decline in post-2020 publications, the most in 2020, as many as 272, but plummeting to 3 in early 2025. This decline occurred due to policy changes after the pandemic, reallocating funding to digital learning, and competition for research priorities. Boaler's book related to Mathematical Mindset 2022 became the publication with the most citations (2329). The VOSviewer analysis results identified four main clusters, with the mathematical mindset being in cluster three. In addition, it found the potential for a weak connection with technological terms, which could be a new research direction. The results of this study provide optimism and opportunities for mathematical mindset research to be more associated with other terms that can be connected, especially in mathematics education research.

Abstract

This research is an ethnographic study using two AI tools (ChatGPT and Gemini AI) to analyze comparatively the different patterns between Javanese and Sundanese batik. The data was obtained from two AI-generated outputs of two prompts focusing on geometric patterns and transformations. The study used a triangulation process by matching and contrasting AI-generated outcomes with previous literature. The findings reveal that: 1) Javanese batik motifs contain more geometric designs, in the other hand, Sundanese batik tends to use more fluid and organic patterns, and 2) the majority of Javanese batik combines both reflection and rotation, whereas Sundanese batik uses translation and reflection. Math properties from both batik designs are inspired by different cultures. Batik patterns from Java represent values such as balance, organization, and class whereas Sundanese batik expresses Sundanese beliefs about respect for nature. It highlights that traditional arts should be integrated into mathematics teaching to better understand and appreciate their role in various cultures.
