Development of Active Mathematics Learning Activities on Linear Equations in One Variable for Grade 7 Students

Abstract

This research aimed to: 1) develop active mathematics learning activities on linear equations in one variable for Grade 7 students to achieve efficiency according to the 75/75 criterion, 2) compare learning achievement before and after learning through active mathematics learning activities on linear equations in one variable for Grade 7 students, and 3) compare mathematical problem-solving ability after learning through active mathematics learning activities on linear equations in one variable for Grade 7 students against the 75% criterion.The sample consisted of 24 Grade 7 students from Laopracha-utis School, Khamcha-i District, Mukdahan  Province, selected through cluster sampling using schools as the sampling unit. The research instruments included 10 active mathematics lesson plans, a learning achievement test, and a mathematical problem-solving ability assessment. Statistical analyses included percentage, mean, standard deviation, dependent samples t-test, and one-sample t-test. The findings revealed that active mathematics learning activities on linear equations in one variable for Grade 7 students: 1) achieved efficiency higher than the criterion at 77.54/78.20, 2) resulted in significantly higher post-learning achievement compared to pre-learning achievement at the .05 level of significance, and 3) enabled students to achieve mathematical problem-solving ability higher than the 75% criterion.
