Developing Fractional Addition and Subtraction Skills Using Proactive Learning Management with Multimedia for Grade 7 Students

Abstract

          The goals of this research were 1) to develop fractional addition and subtraction skills for grade 7 students by using 2) to compare the learning achievement on fractional addition and subtraction for grade 7 students before and after by using and 3) investigate students' satisfaction with active learning management with multimedia for grade 7 students. The target group used in the research was 12 students of grade 7 in first semester of the 2022 academic year at Nong Bua Nai School, Namon District, Kalasin Province, obtained by purposive sampling. The research tools were an active learning management plan with multimedia, the achievement test to measure fraction addition and subtraction skills, an achievement measurement, and a satisfaction questionnaire. The statistics used to analyze the data were mean, standard deviation, and non-parametric statistics, which used the Wilcoxon signed-rank test. The results found that 1) the students had skills on fractional addition and subtraction with an average score was 70.42 percent, which is at a good level. 2) the learning achievements on fraction addition and subtraction using active learning management with multimedia after learning was higher than before at .05 level of significance 3) Students' satisfaction with the mathematics learning management on fractional addition and subtraction for grade 7 student by using active learning management with multimedia is at the highest level.
