Abstract

This study aims to develop PISA model math questions on Change and Relationship content that are valid, practical, and potentially effective to improve students' reasoning and mathematical literacy skills. The method used is design research type development studies, which consists of preliminary and formative evaluation stages. The instrument was developed through a series of evaluation stages, namely self-evaluation, expert review, one-to-one, and small group. The research subjects were VIII grade students of SMP Negeri 1 Indralaya. The questions developed included six items with difficulty levels from level 1 to level 6 and varied contexts (personal, general, and scientific). Based on the analysis of student answers, it is obtained that the questions developed by researchers can be said to be valid and practical, this is supported by the results of the validity, reliability, difficulty level, differentiating power tests quantitatively and declared practical based on the results of the analysis of student answers which show students have been able to understand the questions, the sentences used do not have double meanings and do not cause errors caused by the questions. Thus, the questions developed are declared feasible to be used to measure and train mathematical literacy and reasoning of junior high school students.

Abstract

The low level of mathematical literacy among Indonesian students is reflected in the average results of PISA 2022, indicating the need to develop PISA-style test instruments. Therefore, this study aims to develop PISA-based questions on numbers that are valid and reliable. The method used is a development study consisting of preliminary and formative evaluation stages. The preliminary stage includes analyzing original PISA questions, student needs, curriculum, and determining the material. The formative evaluation stage includes self-evaluation, expert review, one-on-one, and small group discussions. The format of the questions developed is two multiple-choice questions and four contextual descriptions equivalent to PISA. Content validation was tested qualitatively through expert comments, while quantitative analysis was conducted after testing the questions on six junior high school students in Palembang who were selected purposively. Quantitative analysis includes item validity, reliability, difficulty level, and discriminative power. The research results indicate that the questions are valid and reliable based on content appropriateness, ease of understanding, smooth implementation, and time efficiency. These questions can be used as a training tool to improve students' mathematical abilities in accordance with PISA standards. However, this study has limitations due to the limited sample size and only reaching a small group, so it is recommended that further research be conducted with a larger sample size and up to the field test stage.
