Abstract

Primary school pupils’ difficulties in understanding the concept of fractions through conventional textbooks highlight the need for interactive and contextual teaching materials to strengthen numeracy. This study aims to develop and test the validity, practicality, and effectiveness of interactive digital worksheets (E-LKPD) based on Indonesian Realistic Mathematics Education (PMRI) for the topic of fractions. The research employed a research and development method using the ADDIE model, comprising the analysis, design, development, implementation, and evaluation stages. The research instruments consisted of a needs analysis questionnaire, an expert validation sheet, a practicality questionnaire, and a learning outcome test. The research results indicate that the E-LKPD falls into the ‘valid’ category, with content expert ratings of 78%, media expert ratings of 94.2%, and language expert ratings of 95.8%. Usability also falls into the ‘very high’ category, with a percentage of 89.25% in the one-to-one test and 87.25% in the small-group test. The effectiveness of the E-LKPD is demonstrated by an N-Gain value of 0.66, which falls into the moderate category. These findings indicate that the PMRI-based interactive E-LKPD is suitable for use as digital teaching material to strengthen primary school pupils’ understanding of fractions and numeracy skills

Abstract

Study This aim For analyze need development of E-LKPD based on PMRI on material fractions For students of SDN 4 Air Balui , Musi Banyuasin . The research method used is Research and Development (R&D) with the ADDIE development model ( Analysis, Design, Development, Implementation, Evaluation ). At this stage analysis needs , data collected through questionnaires distributed to students and teachers. Analysis results show that student own need tall towards digital- based E-LKPD which is interesting , contextual and supportive understanding draft fractions . As many as 59% of students strongly agree with relatedness draft with life daily , and 41% of students agree . Need towards digital learning media reached 49% strongly agree and 48% agree . This aspect clarity and ease presentation material assessed important by 55% of students who strongly agree and 45% who agree . For educators , PMRI -based E-LKPD is expected can help student understand draft fractions through experience real and improving skills think creative mathematical they. Findings This underline importance development of PMRI -based E-LKPD as a valid, practical and effective learning medium.
