Abstract

The truth-seeking behaviour of students is the main predictor of someone having critical thinking behaviour. Therefore, it is necessary to conduct research related to students' seeking behaviour in responding to mathematical problems. The purpose of this study was to describe the truth-seeking behaviour of students in working on problems with an unknown universe based on the IDEAL problem-solving model. This research was a qualitative descriptive study, with the stages were (1) determining the research subject, (2) making instruments, (3) giving questions to the subject and recording truth-seeking behaviour, (4) analyzing data, (5) triangulating between observations and interviews. interviews, and (5) conclusions. The results of this study are students tend not to behave truth-seeking in working on problems with an unknown universe based on the IDEAL model. However, students did the steps contained in the IDEAL model, although they did not use all the existing stages. In addition, students tend not to give conclusions that are in accordance with the purpose of the question after working on the problem.Perilaku truth-seeking siswa merupakan prediktor utama seseorang memiliki perilaku berpikir kritis. Oleh karena itu, perlu dilakukan penelitian yang berkaitan dengan perilaku trth-seeking siswa dalam merespon permasalahan matematika. Tujuan penelitian ini adalah mendeskripsikan perilaku truth-seeking yang dimiliki oleh siswa dalam mengerjakan soal dengan semesta yang tidak diketahui berdasarkan model pemecahan masalah IDEAL. Penelitian ini merupakan penelitian deskriptif kualitatif, dengan tahapan (1) penentuan subjek penelitian, (2) pembuatan instrumen, (3) pemberian soal kepada subjek dan perekaman perilaku truth-seeking, (4) penganalisisan data, (5) triangulasi antara hasil pengamatan dan wawancara, dan (5) penyimpulan. Hasil dari penelitian ini adalah siswa cenderung tidak berperilaku truth-seeking dalam mengerjakan soal dengan semesta yang tidak diketahui berdasarkan model IDEAL. Tetapi, siswa melakukan tahap-tahap yang terdapat di dalam model IDEAL, meskipun tidak menggunakan semua tahapan yang ada. Selain itu, siswa cenderung tidak memberikan kesimpulan yang sesuai dengan tujuan soal setelah mengerjakan soal tersebut.

Abstract

Conventional mathematics learning is felt to be less interesting and boring for students. Students need innovative learning and make students active in learning. To improve students' understanding of learning mathematics, innovation is needed in innovative learning media. This study aims to produce a product in the form of virtual reality media in mathematics learning based on the group investigation model. This study uses the ADDIE research method with analysis, design, development, implementation, and evaluation stages. Before being tested, the media was validated by a media expert validator with a result of 86% in the "Very Good" category and a material expert with an assessment result of 94% in the "Very Good" category so that "VR Math" was declared valid. The results of the VR Math learning media trial showed that (1) the results of calculating the percentage of students' learning completeness in the experimental class were 90%, (2) the average learning outcomes of the experimental class were better than the control class, (3) there was an increase indicated by a score of N -0.76 gain in the “High” category. Based on the results of the trial, the VR Math learning media was effective for group investigation-based mathematics learning based on the effectiveness indicator, namely achieving 90% classical learning mastery, the experimental class learning outcomes were better than the control class, and there was an increase

Abstract

In Semarang's elementary maths education, augmented reality (AR) and three-dimensional tech are underused in geometry instruction. These technologies promise an engaging and interactive presentation of three-dimensional objects. Presently, educators are confined to traditional tools like PowerPoint, providing a less immersive learning experience. This study addresses this gap with AR Geogebra, a tailored interactive tool for geometry instruction. Developed using the ADDIE model, the study involved fifty fifth-semester university students. Notably, material and media validation scored 90%, deeming it "extremely valid." Practicability, assessed by the experimental class and subject teacher, reached 90%, indicating high practicability. Post-test results showed an N-gain of 0.39 for the exposed group, surpassing the control group's 0.02. In conclusion, AR Geogebra proves an effective pedagogical approach for geometry instruction in elementary maths education.
