A Study of Learning Achievement and Problem Solving Ability on Weather Wonders and Air Phenomena Learning Unit of Grade 3 Students Using Phenomenon-Based Learning with R-C-A Question Technique

Abstract

This research aimed to 1) compare the academic achievement of the learning unit “Wonders of Weather and Air Phenomena” of Grade 3 students before and after learning through phenomenon-based learning combined with RCA questioning technique, 2) compare the academic achievement after learning through phenomenon-based learning with the 70 percent criterion, and 3) compare the problem solving ability of students before and after the learning. The sample consisted of 22 Grade 3 students, the second semester of the 2024 academic year, Ban Maka School (Kongritbuasuwan Anusorn), selected by cluster sampling. The research instrument was a learning management plan using phenomenon-based learning combined with RCA questioning technique, 4 lesson plans. Then, the learning outcomes were measured with an achievement test. Data were analyzed using statistics of percentage, mean, standard deviation, t-test for dependent samples, Wilcoxon Signed-Rank test and Runs test. The research results found that 1) the learning achievement after learning was significantly higher than before learning at the .05 level. 2) the learning achievement after learning was higher than the 70 percent criterion with statistical significance at the .05 level. 3) problem solving ability after learning was significantly higher than before learning at the .05 level.
