Abstract

This study explores how junior high school students understand different types of discounts through percent multiplication. We used the qualitative study and analyzed the in-depth answers of three of the 32 participants as research subjects. The end-of-year discount selection activity provides a daily context to build knowledge about needs and wants. Students engage with open-ended tasks requiring mathematical methods to make financial decisions. These activities help students recognize discounts in everyday life, develop problem-solving strategies, and improve mathematical skills. The article highlights how students analyze various store discounts and guide readers in distinguishing between needs and wants. Early exposure to financial math fosters responsible consumer behavior. The study emphasizes the importance of applying comprehensive information to solve financial problems by connecting mathematics to real-life scenarios. The results indicate that the implementation of an open-ended task has the potential to facilitate understanding of financial decision-making and mathematical skills.

Abstract

The teaching of mathematics in Indonesia faces notable challenges, particularly in effectively conveying mathematical concepts to students. This has created a need for instructional modules that provide better support for learners. Current modules, however, do not adequately incorporate the Pancasila Students Profile (PSP), especially in terms of fostering critical reasoning skills. Therefore, there is an urgent demand for alternative instructional materials based on the Ethno-Realistic Mathematics Education (Ethno-RME) approach, which aligns with the competencies outlined in the PSP—a framework grounded in the nation's foundational values—and connects learning with students' daily experiences. This study aims to develop an Ethno-RME-based module that is valid, practical, and effective in enhancing students' critical reasoning abilities. The research adopts a design research methodology of the development studies type, structured into two key phases: preliminary and formative evaluation. Data collection methods included the use of assessment sheets, walkthroughs, document analysis, and tests of students' critical reasoning skills. The study was conducted with 22 eighth-grade students at a private secondary school in Yogyakarta. The results indicate that the Ethno-RME-based module is both valid and practical, with promising potential to improve students' critical reasoning. Specifically, the module received high validity ratings, with the material scoring an average of 165 out of 175 and the media quality receiving 129 out of 135. The one-to-one evaluation phase produced an average score of 74 out of 75. During the small group trial, the module achieved an average student response score of 66.33 out of 75, and in the field test stage, it scored an average of 64.45 out of 75, confirming its practicality. Furthermore, the second stage of the field test revealed a positive effect on critical reasoning. These findings demonstrate the efficacy of the Ethno-RME-based module in enhancing the critical reasoning skills of students in accordance with the Pancasila Student Profile.

Abstract

Algebra is a very important subject in mathematics learning. Therefore, students especially at seventh-grade must be able to understand this concept well. This study aims to explore information and describe students’ errors in solving algebraic problems. The research method in this study uses qualitative descriptive. The subjects of this study were 36 seventh-grade students of SMP Muhammadiyah Kalasan. The instrument in this study is a test consisting of 10 questions about the operation of algebraic forms. The results showed that students still made some mistakes in solving algebraic problems, such as errors in the variable, errors in negative signs, errors in completing the form of algebraic equations, errors in the operation of the algebraic form, and errors in solving fractions.DOI : 10.22342/jpm.13.1.6668.1-8

Abstract

Penelitian ini bertujuan untuk mengetahui efek dari permainan tepuk tangan secara bersamaan (tepuk bergilir), yang berorientasi konstruktivisme yang valid dan praktis, dalam pembelajaran konsep Kelipatan Persekutuan Terkecil (KPK) siswa kelas IV SD. Pembelajaran yang dilakukan dalam penelitian ini, dibawakan oleh Nila, Sasa, Rully, ditemani oleh bu Neti, selaku guru kelas, dan diikuti oleh 23 siswa. Sebelum memulai pembelajaran, didapatkan informasi, bahwa bu Neti telah mengajarkan materi kelipatan kepada siswa. Sehingga, disain pembelajaran dimulai dengan me-review kembali materi kelipatan, dengan permainan “tepuk bergilir”, kemudian memandu mereka untuk lebih memahami apa itu kelipatan. Selanjutnya, level permainan ditingkatkan, dengan membagi siswa menjadi 2 kelompok dan melakukan permainan diatas secara bersamaan, yang bertujuan menggiring siswa ke arah pembelajaran persekutuan. Akhirnya, pembelajaran ditutup dengan mencari bilangan terkecil dari persekutuan bilangan sebelumnya, sehingga di dapat nilai KPK dari 2 bilangan yang diberikan. Hasil-nya, siswa mampu memahami pelajaran KPK dengan baik dan mampu menyelesaikan soal-soal yang diberikan. DOI: 10.22342/jpm.4.2.406

Abstract

This research begins with the formation of preparatory classes towards OSN Mathematics at Manggarai-NTT Regency level. This is based on the evaluation of the implementation of the Math Olympiad at the elementary level held by the Mathematics Education Department STKIP Santu Paulus. This study aims to improve students’ higher order thinking skills by using Think, Talk, and Write (TTW) strategy in introductory olympiad class. It was action research conducted at Manggarai District with six students taken from different schools selected based on their mathematics achievement. Data were obtained through observation and test. The data analysis and interpretation show that the implementation of Think, Talk, and Write (TTW) strategy can improve students' higher order thinking skills. This can be seen from the increase in the average value of test results in each cycle that is Pre cycle 51.3; cycle I 62.2; and cycle II 71 followed by improvement of learning mastery with presentation of value of each cycle that is pre-cycle 0%; cycle I 50%; and cycle II 83,3%. In particular, one of the students became the first winner in OSK Matematika at Manggarai District level.
