DEVELOPMENT OF LEARNING MANAGEMENT FOCUSING ON THE INQUIRY PROCESS COMBINED WITH THE USE OF QUESTIONS TO ENHANCE THE SUMMARY CONCEPT FOR SECONDARY SCHOOL STUDENTS IN THE SECOND YEAR

Abstract

This study aimed to: (1) develop and determine the efficiency of an inquiry-based learning management approach integrated with questioning to enhance conceptual understanding among Grade 8 students in accordance with the 80/80 criterion; (2) compare students’ conceptual understanding before and after instruction; (3) compare students’ science learning achievement before and after instruction; and (4) examine students’ satisfaction with the learning management approach. The study employed a research and development design. Phase 1 involved developing the lesson plans and determining their efficiency through an evaluation of appropriateness by five experts, followed by a pilot implementation with 42 students who were not part of the sample group. Phase 2 involved implementing the learning management plans with 30 Grade 8/1 students at Kosamphi Witthaya School, Kosamphi Nakhon District, Kamphaeng Phet Province, during the second semester of the 2024 academic year. The sample was selected using simple random sampling. Research instruments included a conceptual understanding test, a science achievement test, and a student satisfaction questionnaire. Data were analyzed using mean, standard deviation, and dependent-samples t-test.

         The results indicated that: (1) the learning management plans were rated at the highest level of appropriateness and achieved an efficiency of 85.27/84.67, exceeding the 80/80 criterion; (2) students’ post-instruction conceptual understanding and science achievement were significantly higher than their pre-instruction scores at the .05 level; and (3) students reported the highest level of satisfaction with the learning management approach. The findings conclude that inquiry-based learning integrated with questioning effectively enhances students’ conceptual understanding and science learning achievement
