Development of 5E Inquiry-Based Learning Activities Combined with Scientific Process Skills Practice Kits on the Topic "Energy on Our Earth" for Grade 3 Students

Abstract

        This research aimed to: 1) develop 5E inquiry-based learning activities combined with scientific process skills practice kits to achieve an efficiency of 75/75; 2) compare students' learning achievement and scientific process skills before and after instruction; 3) compare students' learning achievement and scientific process skills against the established criteria; and 4) investigate students’ satisfaction toward the 5E inquiry-based learning activities combined with scientific process skills practice kits on the topic "Energy on Our Earth" for Grade 3 students. The sample group consisted of 41 students from Grade 3/1 of Anuban Roi Et School during the second semester of the 2022 academic year, selected by cluster random sampling. The research instruments included: 1) science lesson plans, evaluated as highly appropriate; 2) scientific process skills practice kits, also evaluated as highly appropriate; 3) a science achievement test with an Index of Item-Objective Congruence (IOC) ranging from 0.60 to 1.00, a difficulty index between 0.40 and 0.80, a discrimination index between 0.51 and 0.60, and a KR-20 reliability coefficient of 0.94; 4) a scientific process skills assessment with an IOC of 0.90; and 5) a student satisfaction questionnaire with an IOC of 0.84.

  The research findings were as follows:

  1) The learning management process achieved an efficiency of 85.08/91.20, which met the specified criteria; 2) Students’ post-test learning achievement was significantly higher than their pre-test scores at the .05 significance level; 3) Students’ scientific process skills exceeded the 75 percent criterion; and 4) Students reported the highest level of satisfaction with the learning activities.
