This research aims: (1) to develop a learning Instagram Reel for the subject of linear Equations for Junior High School and (2) to find out from the Instagram Reel developed in this study. The research method used is Research and Development (R &amp; R&amp;D) with the ADDIE model, consisting of 5 stages: Analysis, Design, Development, Implementation, and Evaluation. The research subjects were 22 students of SMP Negeri 3 Bantul. The result of this research is Instagram Reels learning for the subject of linear Equations for Junior High School, presented through the Instagram account @mathematics_fun. This Instagram reel was declared suitable for use because the average total validation score for aspects was 4.61 (including the very valid category), and the average student response questionnaire score was 3.91 (including the good category). The implication is that teachers are advised to use Instagram Reels as a learning medium. It is recommended that teachers develop Instagram for other materials.</p> 2022-03-31T00:00:00+07:00 Copyright (c) 2022 UNION: Jurnal Ilmiah Pendidikan Matematika https://jurnal.ustjogja.ac.id/index.php/union/article/view/10080 Pengaruh Model Problem Based Learning dan Discovery Learning Terhadap Kemampuan Pemecahan Masalah 2021-07-18T11:54:03+07:00 Bettri Yustinaningrum bettri_yustinaningrum@yahoo.com Aida Fitri bettri_yustinaningrum@yahoo.com Juliana bettri_yustinaningrum@yahoo.com <p><em>This study aims to compare the mean problem-solving ability of students treated with the problem-based learning with discovery learning on the SPLDV material.

The t test was chosen to be used in analyzing the data resulting from research activities. The t-test describes the difference in learning outcomes for the class before being treated with the STAD virtual flipped classroom after being given treatment. The difference between students who were given the STAD virtual flipped classroom learning treatment can be seen by comparing their average scores. The class learning outcomes before being given the STAD virtual flipped classroom learning treatment were 73.47. Class learning outcomes after being subjected to STAD virtual flipped classroom learning are 82.61. This shows that the class that has been given the STAD virtual flipped classroom learning treatment has better learning outcomes. STAD virtual flipped classroom learning is carried out with the stages of material being studied by students first, then followed by discussions in limited face-to-face meetings in class. Virtual teaching and learning activities are carried out through direct interaction between lecturers and students using video conferencing applications that promote collaboration between students, provide mutual motivation and have an active role as peer tutors. So the implementation of teaching and learning activities using the STAD virtual flipped classroom can provide students with increased learning outcomes and create a learning atmosphere that students will always miss.</p> 2022-03-31T00:00:00+07:00 Copyright (c) 2022 UNION: Jurnal Ilmiah Pendidikan Matematika https://jurnal.ustjogja.ac.id/index.php/union/article/view/11920 Bahan Ajar Elektronik Berbantuan GeoGebra pada Materi Statistika Siswa SMK 2022-02-10T09:53:43+07:00 Rarri Ryandi rarri.bianryandi@gmail.com Diah Dwi diahdwisantri04@gmail.com <p><em>This study aims to utilize GeoGebra electronic teaching materials to create a learning path in understanding statistical material.

The results showed that the difficulties of mathematics teachers in implementing online learning during the COVID-19 pandemic were the lack of understanding of IT, low student activity, insufficient cellphone ownership and unsupportive signals. In addition, solutions that can be done to reduce these difficulties include increasing teacher insight in the IT field, limited face-to-face learning and collaboration of all school members, teachers and students.
