Junior high school students’ mathematical reasoning skills on integer using PMRI and collaborative learning

Abstract

Students need to have good mathematical reasoning skills when learning integer material. The utilization of video media and collaborative learning through the PMRI technique can be used in learning activities to improve mathematical reasoning skills. This study aims to determine mathematical reasoning skills after implementing the learning process using video media with the PMRI approach and collaborative learning integer material for class VII students. This study is descriptive research in which participants are pupils in class VII SMP Srijaya Negara Palembang has 23 students (10 females and 13 males). This study consisted of two meetings. The first meeting focused on the learning process using video material with PMRI and collaborative learning. The second meeting was used to test the results. This study employs observational data gathering techniques, written tests, interviews, and descriptive data analysis approaches. The findings of a study are combining video media and the PMRI technique and collaborative learning on integer subjects in class VII. The skills of students in class VII to reason mathematically was discovered. On the subject of excellent integers, SMP Srijaya Negara Palembang students scored an average of 69.61. The sign of creating assumptions appears to be the most frequent in this study, while the indicator of concluding appears to be the least frequent. Students' mathematical thinking skills can be improved by using video media in conjunction with PMRI and Collaborative Learning during the learning process.

Development of learning video comparison using Palembang jumputan context to determine students' mathematical reasoning

“…In the second indicator, students are able to solve problems by converting them to mathematical language. This agrees with Khoirunnisa and Putri (2022) who say that in this indicator students change the problem into mathematical form and find a solution.…”

“…The low mathematical reasoning ability of students is caused by most teachers who still use traditional approaches in learning mathematics (Kusuma, 2023). Math learning will be more fun if it is related to everyday life (Khoirunnisa & Putri, 2022).…”

“…The importance of learning videos on comparison material with the context of Palembang jumputan fabric as a starting point for learning so that students' mathematical reasoning skills are good. There is previous research on the use of learning videos to determine students' mathematical reasoning ability in various materials by Khoirunnisa and Putri (2022) on integer material, while research by Nabila and Putri (2022) on number pattern material. Previous research that discusses comparison material in various contexts has been conducted by Utari (2017) with the context of empek-empek recipes, while research by Palinusssa et al (2021) used a rural context.…”
