Abstract

Background: This Community Service (PkM) activity aims to enhance the reasoning and proof competencies of Mathematics teachers in Prabumulih City through training in the use of Geometer's Sketchpad software. An initial survey identified that many teachers had a negative perception of mathematical proof, felt difficulty in constructing proofs, and lacked the use of technology in teaching. Methods: The training was conducted in a hybrid format, combining face-to-face and online methods, with an emphasis on interactive approaches. Result: The results showed a significant increase in teachers' understanding of mathematical concepts and their ability to construct proofs. Approximately 90% of teachers stated that evidence-based learning improves the quality of education. Although progress was made, additional training is still needed for some teachers who struggled with using Geometer's Sketchpad. These findings highlight the importance of ongoing support and further training to sustain teachers' competency development, as well as encourage the application of more innovative teaching methods. Conclusion: Thus, this activity is expected to improve the quality of mathematics education in schools and prepare students to face academic challenges in the future.

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.
