Abstract

Background. Spatial visualization ability is an important factor in solving geometric problems because when studying three-dimensional shapes students are not only asked to count to determine a value but also must be able to visualize an object in their minds. If this spatial visualization ability is not developed, it is likely that students will experience difficulties in learning geometry. The purpose of this research is to describe students' spatial visualization abilities in solving geometric problems, which is the aim of this study. The research method used was qualitative research in which data were collected using the results of written tests and interviews with research subjects who were class VIII, totaling 28 students. Students whose answers met the most indicators met the other students to be interviewed further about their spatial visualization abilities. The selection of subjects was based on the results of written tests from 28 students, there was 1 student whose answers met the most indicators than the other students, so these students were selected to be research subjects and further interviewed. The results showed that the results of the written tests and subject interviews were able to fulfill the indicators of imagining, conceptualizing and pattern-finding. The indicator that the subject cannot fulfill is problem solving, this is because students are not careful in writing down the number of cubes that are known in the problem which results in wrong answers. Subjects in this study are said to have spatial visualization abilities, this is due to the compatibility when conducting written tests and interviews.   Latar Belakang. Kemampuan visualisasi spasial merupakan salah satu faktor penting dalam memecahkan masalah geometri karena pada saat mempelajari bangun ruang tiga dimensi siswa tidak hanya diminta berhitung untuk menentukan suatu nilai tetapi juga harus dapat memvisualkan suatu objek di dalam pikirannya. Jika kemampuan visualisasi spasial ini tidak dikembangkan maka kemungkinan siswa akan mengalami kesulitan dalam mempelajari geometri. Tujuan Penelitian ini adalah mendeskripsikan kemampuan visualisasi spasial siswa dalam memecahkan masalah geometri merupakan tujuan dari penelitian ini. Metode Penelitian yang digunakan adalah penelitian kualitatif yang pengambilan datanya menggunakan hasil tes tulis dan wawancara dengan subjek penelitian adalah kelas VIII yang berjumlah 28 siswa kemudian diambil siswa yang jawabannya paling banyak memenuhi indikator dari pada siswa yang lainnya untuk diwawancarai lebih lanjut mengenai kemampuan visualisasi spasialnya. Pemilihan subjek didasarkan atas hasil tes tulis dari 28 siswa, terdapat 1 siswa yang jawabannya paling banyak memenuhi indikator dari pada siswa yang lainnya, sehingga siswa ini dipilih untuk dijadikan subjek penelitian serta diwawancarai lebih lanjut. Hasil Penelitian menunjukkan bahwa hasil tes tulis dan wawancara subjek mampu memenuhi indikator pengimajinasian, pengonsepan dan pencarian pola. Indikator yang tidak dapat dipenuhi oleh subjek yaitu pemecahan masalah, hal ini dikarenakan siswa kurang teliti dalam menuliskan jumlah kubus yang diketahui dalam soal yang mengakibatkan jawabannya salah. Subjek pada penelitian ini dikatakan memiliki kemampuan visualisasi spasial, hal ini dikarenakan adanya kesesuaian ketika melakukan tes tulis dan wawancara.

Abstract

This study aims to analyze the improvement of students' mathematics learning outcomes through the application of the Computational Thinking approach and the Polya problem-solving approach. This study used a quasi-experimental method with a Non-Equivalent Control Group Design. The subjects were 28 students of class VIII A of SMP Negeri 4 Pasuruan as the experimental group and 23 students of class VIII B as the control group. The instruments used were pretest and posttest tests on the data centering material. Data analysis was carried out using the Wilcoxon Signed Rank test because most of the data were not normally distributed. The test results showed a significant improvement in both groups after treatment. However, the improvement achieved by students in the Computational Thinking group was higher than that of the Polya group. This proves that Computational Thinking is more effective in encouraging students to think systematically, analytically, and reflexively in solving mathematical problems.

Abstract

In the modern educational landscape, the integration of technology into mathematics education is crucial, and prospective teachers are expected to be not only passive users but also adaptive developers of digital content. Despite being labeled as the "digital generation," a paradox has emerged where general technological proficiency does not equate to competence in specialized mathematics software. This study addresses the self-paced training needs of prospective mathematics teachers at Universitas PGRI Wiranegara, aiming to improve their ability to adapt learning software effectively. Using a qualitative descriptive approach, data were collected through questionnaires and in-depth interviews with final-year students, with the instruments validated through expert assessment and data triangulation to ensure reliability and accuracy. The study revealed a significant gap in technological proficiency: 88% of respondent demonstrated proficiency in basic visualization techniques, but only 4% mastered advanced features such as scripting. Analysis of self-paced learning patterns highlighted issues such as fragmented learning, reactive learning, and high cognitive load, underscoring the urgent need for a structured, project-based self-paced training roadmap. This roadmap will guide prospective teachers from understanding mathematical abstractions to effectively implementing digital functions, empowering them to become competent digital content developers and increasing the effectiveness of their teaching in technologically integrated classrooms.

Abstract

Kecemasan matematis merupakan faktor yang dapat menghambat kemampuan siswa dalam pemecahan masalah matematika, khususnya yang membutuhkan penalaran sistematis. Penelitian ini bertujuan menganalisis bagaimana siswa mengatasi kecemasan tersebut berdasarkan langkah-langkah Polya: memahami masalah, merencanakan, melaksanakan rencana, dan memeriksa kembali. Menggunakan pendekatan kualitatif dengan studi kasus, penelitian ini dilakukan di MTs Yayasan Tarbiyah Islam Nguling. Subjek penelitian adalah 15 siswa kelas VIII B yang mengikuti tes pemecahan masalah, di mana tiga siswa dengan gejala kecemasan dipilih untuk wawancara mendalam. Instrumen penelitian mencakup tes berbasis langkah-langkah Polya, lembar observasi, dan pedoman wawancara. Hasil penelitian menunjukkan bahwa kecemasan siswa muncul pada aspek kognitif, afektif, dan psikomotorik. Meskipun demikian, siswa memilikicara mengatasi diri, seperti menenangkan diri, membaca ulang soal, menghubungkan dengan konsep yang dikuasai, serta mencari bantuan dari teman atau guru. Dapat disimpulkan bahwa cara pengendalian diri ini mampu membantu siswa menyelesaikan soal sesuai dengan tahapan Polya meskipun kecemasan matematis memengaruhi proses pemecahan masalah mereka.

Abstract

Mathematical problem-solving skills are essential for students to succeed in the 21st century, yet many struggle to apply mathematical concepts in real-life situations. This research addresses the need for innovative learning media by developing Statblithz Game, an educational game designed to train and enhance students’ mathematical problem-solving abilities. The study employed a Research and Development approach using the ADDIE model, involving stages of analysis, design, development, implementation, and evaluation. Participants included middle school students who engaged with the prototype and provided feedback through questionnaires, expert validations, and pre- and post-tests measuring problem-solving performance. The results indicated that Statblithz Game is highly feasible, with expert validation scores averaging 89%. Moreover, students’ problem-solving test scores improved by an average of 25% after using the game. In conclusion, the Statblithz Game effectively enhances mathematical problem-solving skills and offers an engaging alternative to traditional mathematics instruction. The impact of this research lies in providing educators with an innovative and interactive tool that can foster critical thinking and improve student learning outcomes in mathematics.
