STEAM - BASED LEARNING MANAGEMENT FOR DEVELOPING SCIENTIFIC COMPETENCIES OF SECONDARY STUDENTS MEASURED USING AN ASSESMENT OF SCIENCE LITERACY IN LINE WITH THE PROGRAM FOR INTERNATIONAL STUDENT ASSESSMENT UNDER THE SECONDARY EDUCATIONAL SERVICE AREA OFFICE LAMPANG LAMPHUN AREA 35

Abstract

The purposes of this research study were as follows: 1) to study the effect of STEAM - based learning management on the scientific competencies of secondary students, 2) to study the modeling skills of secondary students after implementing the STEAM - based learning management, and 3) to study how satisfied the secondary students under The Secondary Educational Service Area Office Lampang Lamphun Area 35 were with the implementation of STEAM - Based learning management that they received. This study was a quasi - experimental study and has a single control group. The research had pre - test and post - test design, which tests before and after the implementation of STEAM - Based learning management to improve the scientific competencies of the secondary students. Scientific competencies were measured using an assessment of science literacy in line with the Program for international student Assessment for secondary student. The sample group in this research was 30 students in the first semester of the 2023 academic year at a selected school in Lampang Province. The secondary students were selected from the population using simple random sampling from the secondary students population at the selected school. The research instruments used were as follows: 1) a STEAM based learning management plan, 2) a scientific competencies test,             3) a modeling skill assessment questionnaire, and 4) a satisfaction assessment questionnaire. The data were analyzed by using the following statistical measures and tests: means, percentages, standard deviations, and t - tests. The research results were as follows: 1) the secondary students had higher scientific competencies after learning than before learning at the statistical significance level of p = 0.05, 2) the secondary students had modeling skills assessed at 87.87 percent, the highest level in the rubric ( = 4.39, S.D. = 0.31) and 3) the secondary students gave a high satisfaction rating to the implementation of STEAM - based learning management ( = 4.47, S.D. = 0.46).
