THE DEVELOPMENT OF BASIC SCIENTIFIC PROCESS SKILLS AND SCIENTIFIC ATTITUDES FOR PRATHOMSUKSA 4 STUDENTS USING A 5-STEP SEARCH-BASED LEARNING MANAGEMENT SYSTEM WITH POE TECHNIQUES

Abstract

This research aimed to 1) compare knowledge and understanding of basic science process skills against a 70% criterion, 2) compare knowledge and understanding of basic science process skills before and after instruction, 3) compare the ability to use basic science process skills against a 70% criterion, and 4) compare scientific attitudes before and after instruction. The research design was a One Group Pretest-Posttest Design. The sample consisted of 96 fourth-grade students from four classrooms in the Doi Santikhiri Educational Development Network during the first semester of the 2024 academic year, selected using stratified random sampling. The research instruments included: 1) a science lesson plan using a five-step inquiry-based learning approach combined with the POE technique, 2) a test measuring basic science process skills, 3) an assessment form for basic science process skills, and 4) a scientific attitude scale. Statistical analysis included percentages, means, standard deviations, and t-tests.

The research findings revealed that: 1) Post-instructional knowledge and understanding of basic science process skills were significantly higher than pre-instructional knowledge and met the 70% criterion; 2) The ability to use basic science process skills after the instruction met the 70% criterion; and 3) Scientific attitudes after the instruction were significantly higher than pre-instructional knowledge at the .05 statistical significance level. This demonstrates that the five-step inquiry-based learning approach combined with the POE technique, which emphasizes student self-construction of knowledge using the scientific process to discover correct information or approaches, can effectively improve the basic science process skills and scientific attitudes of fourth-grade students.
