THE DEVELOPMENT OF LEARNING MANAGEMENT ACTIVITIES BY APPLYING STEM EDUCATION TO PROMOTE THE SCIENTIFIC PROBLEM- SOLVING THINKING ABILITY OF MATHAYOMSUKSA 3 STUDENTS

Abstract

This research was conducted to design and develop an innovation by using Developmental research’s type I. This research is divided into two phases: development phase and evaluation phase, which this study is in phase 2. The instruments of the research consisted of 1) 6 lessons plans, 2) the scientific problem-solving thinking proficiency tests, and 3) a satisfaction questionnaire. Statistics used in analyzing the data were percentage, mean, and standard deviation. The sample group was 30 Mathayomsuksa 3 students studying in semester 1/2022 at one of a school in Kalasin Province. Data were collected through 1) 20 items of the scientific problem-solving thinking proficiency tests, and 2) 10 items of the satisfaction questionnaire. The results found that 1) the development of learning management activities by applying STEM education for Mathayomsuksa 3 students met the efficiency at 80.50/84.17, which higher than the set criteria of 80/80, 2) The scientific problem-solving thinking ability of Mathayomsuksa 3 students after learning by applying STEM education was 77.83, which higher than the 70 percent criteria, and 3) students’ satisfaction toward the learning activities by applying STEM education was at the highest level ( = 4.59, SD = 1.82).
