Development of constructivism-based mathematics interactive learning media tools on the material of constructing a flat side space for class VIII junior high school students

Abstract

This study originated from students who had difficulty understanding the material of flat-sided shapes. Students often make mistakes in solving flat-sided shapes, including errors in calculations, and students having difficulty in visualizing images, especially in the material of flat-sided shapes. Also, many students still entered the formula incorrectly. One way to overcome this problem is to develop media-based interactive learning with a constructivist approach. This study aims to produce constructivism-based interactive mathematics learning media that is valid and practical on flat-sided building materials for class VIII junior high school students. This study describes the effectiveness of constructivist-based interactive learning media that is valid and practical flat-sided building materials for junior high school students VIII. The type of research used is development research using the Plomp model, which consists of three phases: the initial investigation phase, the development phase or prototyping, and the assessment phase. The preliminary research needs analysis, curriculum analysis, student analysis, and concept analysis were carried out. At the stage of developing or making a prototype, the researcher designs constructivism by paying attention to content, language, presentation, and graphics. Media-based interactive learning constructivism is validated by experts in mathematics, media, technology, and language education. Practicality is seen through the analysis of the implementation of learning observations, interviews, and student and teacher response questionnaires. Effectiveness is seen through the results of the analysis of student activities and learning outcomes.
