The Self-Directed Learning Management to Enhance Analytical Thinking Learning and Learning Achievement About “Solar System” for Grade 9 Students

Abstract

The purposes of this research were 1) to compare the analytical thinking of grade 9 students between before and after the self-directed learning, and 2) to compare leaning achievement of grade 9 students after the self-directed learning on “Solar System” with the criteria of 70 percent. The sample was 43- students of class 3/1 in the first semester of academic year 2023 in Kalasinpittayasan school, under the Secondary Educational Service Area Office Kalasin from cluster random sampling. The research instruments were, 1) 5-lession plans of self-directed learning on “Solar System” for 14 hours, which their appropriate between 4.10-4.20, as very appropriateness level, 2) the choices  20-items analytical thinking objective test, with difficulty index ranged from 0.34 to 0.78, discrimination power ranged from 0.32 to 0.62 and reliability of 0.91, and 3) the choices 30-items of leaning achievement test on “Solar System” with difficulty index ranged from 0.59 to 0.78, discrimination power ranged from 0.31 to 0.74, and reliability of 0.93. The data analysis statistics were mean, standard deviation, dependent-sample t-test and one-sample t-test.           

The research results showed that 1) grade 9 students who learned by self-directed learning had analytical thinking higher than before the learning statistically significant at .05 level. And 2) grade 9 students had learning achievement after the self-directed learning higher than the criteria of 70 percent statistically significant at .05 level.
