Abstract

Mathematical Problem-Solving Ability (KPMM) is one of the essential skills that must be developed, as it trains students to formulate appropriate solution strategies, understand the meaning of each step, and cultivate systematic thinking habits. One of the tools that can be utilized to support the development of KPMM is the use of Student Worksheets (LKPD). Various studies have demonstrated the effectiveness of using LKPD in improving students' KPMM; however, comprehensive reviews that specifically examine the effectiveness of LKPD based on educational level and the form of LKPD used are still limited. Therefore, this study aims to analyze and synthesize previous research findings on the effectiveness of LKPD in supporting students’ KPMM in terms of educational level and LKPD format through a meta-analysis method. The population and sample of this study consist of journal articles and national conference proceedings selected according to PRISMA guidelines. The results of the meta-analysis show that the use of LKPD has a very strong influence on enhancing students' KPMM, with an effect size of 2.123. Based on educational level, LKPD is proven to be more effective when used at the junior high school level (SMP) compared to the senior high school level (SMA), while in terms of format, digital LKPD is more effective than printed LKPD in supporting students' KPMM.

Abstract

The purpose of this research is to analyze students' mathematical communication ability (MCA) through test questions on geometry transformation material that contains MCA indicators. This research uses a descriptive quantitative approach, by measuring the validity of the questions, then giving test questions to students, calculating student scores, and grouping them by category, and analyzing student answers. The research was conducted at a senior high school in Indragiri Hilir, the research sample was class 12 students majoring in mathematics and science as many as 20 people, with the assessment method and research instruments namely open description questions. The test questions given have been tested for validity using the Aiken index, and are in accordance with the MCA indicators set. The results of the study based on student test scores obtained 20% of high category students, 65% of medium category students, and 15% of low category students in solving MCA test questions. From the results of this study, it is necessary to strengthen learning to facilitate students' MCA.
