A Study of Learning Achievement on a Unit of Thai Society Can Change Starting with Us and Problem Solving Thinking Ability of Grade 9 Students through Problem-Based Learning with Fishbone Diagrams Technique

Abstract

This research article aimed to: 1) Compare the learning achievement in the learning a Unit of Thai Society Can Change Starting with Us, 2) Compare the students’ learning achievement after the learning management with the criterion of 70 percent, and 3) Compare the students’ Problem Solving Thinking Ability before and after the learning Of Grade 9 Students. The sample group of this study were 39 students of grade 9 students class 3/3 of the first semester academic year of 2025 at Phimai Wittaya school, Nakhonratchasima province. The sample was selected using cluster random sampling. The research instruments were lesson plans using problem-based learning with fishbone diagrams technique, with a total of 12 hours of instruction. The lesson plans were evaluated for consistency and appropriateness, with an average score of 4.44, indicating the highest level of appropriateness. The achievement test had a reliability coefficient of 0.87, and the problem solving thinking ability test had a reliability coefficient of 0.83. This study was a preliminary experimental research using a one-group pretest–posttest design. The data were statistically analyzed by percentage, mean, Standard Deviation and t-test.

          The research found that:

1. The students’ learning achievement after learning through phenomenon-based learning combined with graphic organizers was significantly higher than before learning at the .05 level.
2. The students’ learning achievement after learning was significantly higher than the 70 percent criterion at the .05 level.
3. The students’ problem solving thinking abilities after the learning were significantly higher than before learning at the .05 level.
