Abstract

This study focuses on analyzing the influence of the RME (Realistic Mathematics Education) approach combined with open-ended questions and student creativity on mathematics learning achievement, as well as testing the interaction between the approach and student creativity in influencing mathematics learning achievement. The study employs a quantitative approach and quasi-experimental research method. The study was conducted at SMP Negeri 2 Teras, Boyolali, with 2 7th-grade classes as samples, totaling 63 students, selected randomly. Data were collected using test methods, a creativity indicator questionnaire, and documentation. Validity tests, t-tests, two-way ANOVA with unequal cells, and descriptive analysis of the collected data were then conducted. The study findings reveal a significant difference in the RME approach based on open-ended questions and creativity levels on learning outcomes after treatment on students. However, no interaction was found between the learning approach and creativity, meaning the effectiveness of the RME approach with open-ended questions does not depend on students' creativity levels. The RME approach with open-ended questions serves as an effective and inclusive learning method to enhance mathematics learning achievement across various student creativity levels.Keyword: Realistic Mathematics Education, Open-ended Question, learning achievement

Abstract

Research on mathematics education that specifically focuses on students with low-average IQs remains limited, even though these students require attention and appropriate learning strategies. This study aims to determine the effectiveness of using Napier’s bones in improving multiplication and division skills among students with low-average IQs. The research method employed a single-subject research (SSR) design with an A-B-A design, consisting of baseline-1, intervention, and baseline-2 phases. The research subject was a 10th-grade student with a low-average IQ who struggled with multiplication and division operations. The results of the study showed that the use of napier’s bones had a positive effect on improving the multiplication and division operation skills of the participant. This was evidenced by an increase in answer accuracy across each phase, from 20% correct answers in the baseline-1 phase to 99% in the baseline-2 phase. There was also a decrease in task completion time in each phase, accompanied by a trend toward improvement in the data and a low overlap of 0% between the baseline and intervention phases. These findings indicate that the use of napier’s bones as an intervention can significantly improve the participant’s multiplication and divition skills.Keyword: Napier’s Bones, Low average IQ, Perkalian dan Pembagian

Abstract

This study aims to develop a Case-Based Learning-based LKPD integrated with character education on SPLDV material. This study uses the ADDIE development model which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects were 31 ninth-grade students of SMPN Mubeli who were selected by purposive sampling. Product validity was assessed by material experts, media experts, and character education experts. The practicality of the LKPD was measured through teacher and student response questionnaires, while effectiveness was analyzed based on the results of the post-test and student character questionnaires. The results showed that the developed LKPD had a very high level of validity with an average score of 90%. The practicality level of the LKPD was in the very practical category with an average of 91.3%. Furthermore, the Student Worksheet (LKPD) proved effective in improving student learning outcomes, with an average post-test score of 81.71 and classical completion reaching 100%. The character questionnaire results also showed improvements in critical reasoning, honesty, and responsibility, all within the good category. Thus, the Case-Based Learning-based LKPD, integrated with character education based on the local context of NTT, is declared valid, practical, and effective for use in SPLDV learning.Keyword: Student Worksheet, Case Based Learning, Character Education, SPLDV
