Abstract

This study aims to use the Pendidikan Matematika Realistik Indonesia (PMRI) approach to measure the mathematical reasoning ability of grade VII students in answering PISA-like mathematics problems on number content in the context of COVID-19. This study employs descriptive research with 34 participants from a junior high school in Palembang, Indonesia. Tests, interviews, and observations were utilized to collect data. The method of analysis adopted is descriptive. Google Meet is used to facilitate learning. Learning the PMRI technique was accomplished in this study by assigning sharing and jumping tasks. That is, assignments for students to discuss with each other have different levels of difficulty, followed by two exam questions. In the context of COVID-19, the test questions are PISA-like maths problems. The results show that students’ average mathematical reasoning skill is 63,037, with mathematical manipulation a common indicator. Most students have exhibited indications for presenting conjectures. However, only a few students have put down indicators for drawing logical conclusions, so drawing logical conclusions is an indicator that students rarely see. Overall, grade VII students' mathematical reasoning skills in answering PISA-like mathematics questions on number material in the context of COVID-19 utilizing the PMRI approach is good since students are used to modeling contextual problems such that mathematical manipulation indicators occur.

Abstract

The quality of education in Indonesia has yet to be able to balance the importance of mathematical literacy. It can be seen from the OECD's data that a mathematical literacy achievement score of 379 shows that the literacy ability of Indonesian students is still low. This research aimed to develop PISA-like problems that are valid and practical and potentially affect mathematical literacy skills using the context of immunity during a pandemic. This research used the Inquiry-Based Learning (IBL) model in small group and field test stages. The subjects in this study were eighth-grade students aged 13-15. The data were analyzed qualitatively through observations, interviews, and tests. This study produces one unit of sharing task and jumping task and three evaluation problems with characteristics of the content used, name change and relationship, and personal and social contexts. Levels by the framework PISA 2022, namely levels 3, 4, and 5, are process competence and mathematical literacy skills. Using language following language standards can be understood and interpreted well by students. Thus, this research produces the developed PISA-like problems that are valid and practical and potentially affect mathematical literacy skills and life skills in dealing with the pandemic.
