Abstract

This research aims to develop an e-module for flat shape geometry using a constructivist approach on the topic of area and perimeter of flat shapes. The method used is research and development (R&D) based on the ADDIE model. The data collection techniques used by researchers were observation, interviews, and questionnaires. Feasibility of teaching materials by conducting validity tests and practicality tests. The validity test was carried out by three experts, namely material experts, language experts and media experts. The practicality of teaching materials was obtained through a practicality test carried out with two teachers, three individual students (one-to-one), and ten small group students (small group test). The results obtained from experts show that the teaching materials developed received a validity value with an average percentage of 0.95 (very valid). The teachers and students also gave a positive response to the practicality of the e-module, given a score by the teacher, the overall average percentage was 97.5% (very practical), three individual students (one-to-one) obtained an average percentage of 97.5% (very practical). The overall average was 93.89% (very practical), and ten small group students obtained an overall average percentage of 96.33% (very practical). So that the teaching materials produced in the form of flat shape geometry e-modules using a constructivist approach in elementary schools meet valid and practical criteria, so they are suitable for use in the mathematics learning process.

Abstract

GeoGebra is dynamic mathematics software that is utilized as an alternate learning media for studying Mathematics in the contemporary technology development period. Learning using GeoGebra can help students increase their knowledge of ideas and develop their mathematical thinking abilities. In this project, we apply a design research technique to create and test a GeoGebra exercise. The design study approach begins with the creation of GeoGebra-based activities on fraction addition by re-editing an existing GeoGebra design on the GeoGebra website and then testing it with five primary school students. Following the activity, we conducted interviews with students to determine the level of their comprehension of the idea of adding fractions. According to the findings of this study, pupils began to grasp and comprehend adding fractions since they could directly view how the fractions formed. However, some students continue to struggle with computer use owing to a lack of prior expertise.
