THE DEVELOPMENT OF LEARNING OUTCOMES ON LINEAR EQUATIONS OF TWO VARIABLES FOR MATTHAYOMSUKSA 1 STUDENTS TAUGHT BY THE KTS LEARNING PROCESS

Abstract

The objectives of this research were: (1) To investigate the effectiveness of the KTS Learning Process in improving Matthayomsuksa 1 students’ learning outcomes with a target score of 80 percent; (2) To compare the students’ learning outcomes on “linear equations in two variables”  before and after being taught through activities based on the KTS Learning Process; and (3) To investigate the students’ opinion towards these learning activities.

The research was experimental research. The study sample consisted of 30 Matthayomsuksa 1 students of Sarasas Witaed Suksa School in Samutprakan Province, selected by cluster random sampling. The instruments used for data collection were (1) KTS-based lesson plans; (2) tests for measuring learning outcomes on the topic of linear equations in two variables; and (3) a questionnaire on the students’ opinion towards the learning activities. The statistical tools used for data analysis were mean, Standard Deviation, and dependent sample t-test.

The researcher found that (1) The students achieved a mean score of 84.68% after they were subjected to learning activities based on the KTS Learning Process; (2) The students’ post-activities learning outcome was higher than their pre-activities learning outcome, with a statistical significance level of 0.01; and (3) Overall the students expressed a high level of agreement towards these learning activities.
