Developing Mathrun with construct 2 on the solid geometry with flat faces for junior high school

Abstract

Abstract This study aims to: 1) produce Mathrun with Construct 2 on the Solid Geometry with Flat Faces for Junior High School which is valid, practical, and effective. The subjects of this study were 8th grade students of MTs Madani Alauddin Pao-Pao, Gowa in the 2019/2020 school year. This study used a development model proposed by Borg and Gall with 10 stages, namely: 1) problem analysis; 2) Media Design; 3) Product improvement; 4) Individual Test; 5) Validation; 6) Small Group Test; 7) Repair; 8) Field Test; 9) Repair; 10) Dissemination and Reports. However, due to limited time, funds and personnel, this research was limited to the 9th stage. The data collection instruments used questionnaires, responses and test questions. The validation was carried out by education experts, teachers and students. Based on the results of the validation of the feasibility average score for the development of learning media using the Construct 2 software by educational experts, it was obtained 3.40. The practical aspect based on the teacher’s assessment of mathematics was 3.45 which is good criteria. The score of practicality based on the students’ attractiveness was 3.449 which is very good criteria. Meanwhile, the average learning outcome test is complete. Therefore, it can be concluded that the learning media developed have met the criteria of validity, practicality, and effectiveness.
