Development and effectiveness of mobile learning teaching materials to increase students’ creative thinking skills

Abstract

This study aims to develop mobile learning (m-learning) teaching materials on straight-line equations and analyze its effectiveness in increasing junior high school students’ creative thinking skills. The method used is the R&D developed by Alessi and Trollip. The stages of this research include planning, design, and development. The planning stage includes determining the scope, identifying existing teaching materials and student characteristics, and collecting references. The design stage includes analysis of the material concept, making flowcharts and storyboards of teaching materials. The development stage includes preparing teaching materials through expert validation and two trials, making mobile learning applications, and evaluating teaching materials to analyze their effectiveness. The teaching materials were evaluated by material, and media experts then tested on 30 students. The m-learning teaching material developed is an Android smartphone application that students can use as a support source for learning mathematics. This study’s subjects were all class VIII Yastrib Junior High School students, as many as 30 people. The results showed that the m-learning teaching materials on straight line equations developed were feasible to use. Their effectiveness in developing creative thinking skills in the learning process was considered adequate for students with an effect size value of 2.51, which was in the very high category.
