The development of mathematics learning devises based on the constructivism approach to improving the reasoning ability of the junior high school students in grade 8

Abstract

This project aims to create a constructivism-based mathematics learning gadget that will help students enhance their thinking abilities - developing learning gadgets in Lesson Plans and Student Worksheets for junior high school students in grade 8. The learning gadgets were designed utilizing the Plomp paradigm, which entails three stages: basic study, prototyping, and evaluation. Valid learning devices satisfy the requirements for validity in terms of content and constructs. Self-evaluation forms, lesson plan validation sheets, and student worksheet validation sheets were employed in this study. Five specialists will validate the learning devices: three in mathematical education, one in educational technology, and one in Indonesian. The validation findings from experts suggest that the learning tools were built by reasonable standards.
