Development of Mathematics Learning Activity Set Solving Linear Equation One Variable to Enhance Ability Achievement of Mathematics for Grade One Lower Secondary School Students

Abstract

The purposes of this study were 1) to develop and find out the efficiency the set of Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students by the criterion at 80/80. 2) to compare the studying achievement on using the set of Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students between Pre-test and Post -test. 3) to study the students’ satisfaction to the instruction on using the set of Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school. The research was Experimental Research; One-Group-Pretest-Posttest Design. The study was divided into 2 steps: Step 1: Develop and find out the efficiency the set of Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students by the criterion at 80/80. Step 2: Experimented the learning activities the set of Mathematics learning activity set solving linear equation one variable. The grade one lower secondary school students 25 sampling students who were studying in the first semester in 2021 of Ban Mae OmKi School in The Song Yang District Tak Province by purposive sampling. The studying tools were 1) Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students 2)achievement test and 3) satisfaction questionnaire, analyzing the data by using percentage Dependent t-test and mean. The results were as follows, Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students was higher than the criterion at 80.70 / 83.20  The studying achievement on the set of Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students; Post –test  was significantly  higher  than  Pre–test  at level .05 and The students’ satisfaction to the instruction on using Mathematics learning activity set solving linear equation one variable to enhance ability achievement of mathematics for grade one lower secondary school students was appropriate at highest level.
