Developing Geometry Students Worksheet Based on Realistic Mathematics for Learning in Elementary School

Abstract

This study aims to develop Geometry Students Worksheet based on Realistic Mathematics for Learning in Elementary Schools. This study conducted for one year in elementary schools in DKI Jakarta. This study is a research and development (Research & Development/R & D) using mixed methods research with adapted from the models of Borg and Gall and models of Dick, Carey and Carey. Based on this model, there were four major stages, namely stages: (1) Research and information gathering that includes preliminary studies and needs analysis; (2) development of a draft that includes planning and developing the initial form of the product; (3) product testing and revision which includes expert testing/validation (expert judgment), one-on-one testing, small group evaluation, field testing, for each trial possible the revision of the product being developed; and (4) finalization and dissemination. The results showed that the use of Geometry Students Worksheet Based on Realistic Mathematics was able to improve the mastery of conceptual knowledge and procedural geometry of elementary school students. For that reason, Geometry Students Worksheet Based on Realistic Mathematics can be used as one of the Students Worksheet models used in mathematics learning in elementary schools. The results of this study recommend that Geometry Students Worksheet Based on problembased learning Geometry Students Worksheet Based on inquiry, Geometry Students Worksheet Based on scientific approaches, Geometry Students Worksheet Based on 4C skills (Critical Thinking, Creative, Collaborative, and Communication), and others.

Analysis of Weaknesses Among Second-Grade Primary School Pupils on Learning Geometry Topic

“…This shows that students need help and guidance when learning this topic to improve their understanding. According to Iva Sarifah and Endang (2019), a teacher needs to plan and design creative lessons to help pupils learn the objects contained in geometry. 160 pupils (72.7%) agreed on item 12, which indicates that they face difficulties in problem-solving especially involving long sentences.…”
