Abstract

This research aims to develop LKPD based on problem based learning on social arithmetic subject matter for class VII students of SMP Negeri 5 Merangin which is valid, practical, and effective. This form of research is known as Research and Development (R&D) and uses the ADDIE development model which has five stages, namely Analysis, Design, Development, Implementation, and Evaluation. The instrument used was a validation sheet filled out by five validators, a practicality questionnaire sheet and an interview guide for student responses and effectiveness in the form of observation sheets and learning outcomes test questions. These results show that the average score of the material expert validation is 4.27, the linguist validation is 4.40, and the media expert validation is 4.68. The overall validation value of 4.45 has a very valid category. The results of the student response questionnaire obtained a percentage of 80.32% having a fairly practical category. Student learning activities get an average percentage of 76.57% having an active category and the percentage of classical learning outcomes of 76.92% having an effective category. Thus, this research resulted in PBL-based LKPD for social arithmetic subject matter for grade VII students of SMPN 5 Merangin which was valid, practical, and effective.

Abstract

Mathematical communication is essential for students to express, interpret, and represent mathematical ideas. This study aimed to describe grade XI students’ mathematical communication ability on sequences and series based on three communication indicators. A descriptive quantitative secondary analysis was conducted using 60 student score records available in the original research dataset. The instrument consisted of two open-ended problems on an arithmetic sequence and a geometric series; each response was scored on three indicators: expressing mathematical ideas in written/visual forms, understanding and evaluating mathematical ideas, and using mathematical terms, notation, and structures. Descriptive statistics and percentage achievement were calculated from item-level scores. The overall mean score was 7.30 out of 12 (60.83%). Indicator 1 reached 66.25%, indicator 2 reached 53.75%, and indicator 3 reached 62.50%. Performance on the second problem (69.72%) was higher than on the first problem (51.94%). The findings indicate that students’ main difficulty lies in understanding, interpreting, and evaluating mathematical ideas, particularly when generalizing a sequence pattern into a formal expression. Instruction should therefore provide more opportunities for students to explain reasoning, evaluate representations, and justify the use of symbols and formulas
