Abstract

This study discusses the development of learning design for derivative topics based on Realistics Mathematics Education (RME). The design developed is different from the designs that have been developed by previous researchers, where in this study, the derivative concept was introduced through the flying fox trajectory, which refers to students' understanding of limits and average velocity. This development aims to obtain a valid, practical, and effective learning design in derivative topics to develop students' mathematical problem-solving abilities. The development model combines the Plomp and Gravemeijer & Cobb models, which are divided into the preliminary research stage, the development or prototyping stage, and the assessment stage. In the preliminary stage, needs analysis, curriculum analysis, concept analysis, and literature review are carried out. Product prototype development is carried out at the development stage, and formative evaluation consists of self-evaluation, expert validation, one-to-one, and small group phases. In this article, the study focuses on findings from one-to-one activities at the development stage. Through one-to-one activities, the resulting design was tested on three students with different abilities to find out whether this product could later be implemented in the classroom. After students learn to use the design, at the end of the activity, students are given a problem-solving ability test to determine the impact of the design on students' problem-solving abilities. The final product obtained is Local Instructional Theory (LIT) of derivative topics, valid, practical, and impact students' problem-solving abilities of RME-based teacher and student books

Abstract

The purpose of this research is to evaluate whether or not students in the eighth grade at SMP Negeri 2 Betara in the Tanjung Jabung Barat Regency can improve their mathematical critical thinking skills by using mobile learning that is based on problem-based learning (PBL). The participants in this research were all eighth-graders from one junior high school in the Tanjung Jabung Barat Regency. There were a total of 128 students included in this study, and they were distributed across four classes. The sample was selected from as many as two classes, specifically VIIIA with a total of 28 students serving as the experimental group and VIIIB with a total of 28 students serving as the control group. The analysis of the data reveals that the Zcount value is 10,099, and the significance value is 0.000< 0.005; these values were determined to be significant. Therefore, the working hypothesis or alternative hypothesis that was proposed in this study is accepted. It states that there is a difference in the average critical thinking of students who use PBL-based mobile learning compared to students who use standard teaching materials. While the null or nil hypothesis, which states that "there is no difference in the average critical thinking of students who use PBL-based mobile learning and students who use conventional teaching materials," is rejected.
