A Study of Learning Outcomes in the Creative Invention Learning Unit on Human and Animal Life and Creative Problem-Solving of Grade 3 Students Through STEAM-Based Learning

Abstract

This research article aimed to: 1) examine the learning outcomes of Grade 3 students by 1.1) comparing pre-test and post-test learning achievement, 1.2) comparing post-test achievement against the 70% criterion, and 1.3) evaluating the quality of students’ work produced through STEAM-based learning; and 2) compare students’ creative problem-solving skills before and after instruction. The sample consisted of 11 Grade 3 students from Ban Nong Yai School, selected through cluster sampling and divided into three groups (4, 4, and 3 students). The research instruments included three STEAM-based lesson plans (totaling 12 instructional hours), which were validated for content appropriateness (M = 4.87, indicating the highest level of suitability), a learning achievement test (reliability = 0.90), a product quality assessment form (reliability = 0.73), and a creative problem-solving assessment form (reliability = 0.81). This study employed a pre-experimental one-group pretest–posttest design. Data were analyzed using percentage, mean, standard deviation, and t-test.

          The research found that:

1. Students’ post-test learning achievement was significantly higher than their pre-test scores at the .05 level;
2. Post-test learning achievement was significantly higher than the 70% criterion at the .05 level;
3. The overall quality of students’ work was rated at a very good level; and
4. Students’ creative problem-solving skills after instruction were significantly higher than before instruction at the .05 level.
