The Development of Evaluate and Design Scientific Inquiry Competency Using Project-Based Learning in Science Project Subjects for Grade 11 Students

Abstract

The objectives of this research are (1)develop learning activities based on project-based learning to enhance students' ability to evaluate and design scientific inquiry processes, (2)assess students' ability to evaluate and design scientific inquiry processes compared to the 70% criterion, and (3)study students' satisfaction with project-based learning. The sample consisted of 24 Grade 11 students from Princess Chulabhorn Science High School Mukdahan, enrolled in the second semester of the 2024 academic year. The sample was selected using a cluster random sampling method, with the classroom as the unit of selection. The research instruments included (1) 12 lesson plans, each lasting one hour, (2)an assessment tool measuring students' ability to evaluate and design scientific inquiry processes, and (3)a 15-item student satisfaction questionnaire. The data were analyzed using percentage, mean, and standard deviation.

          According to the study’s findings,

1. The developed learning activities across the three units S.I, G.I and O.i consisted of five steps: (1) defining the situation, (2) planning the process, (3) implementation, (4) summarizing and discussing, and (5) evaluation. The appropriateness of the activities was rated at the highest level (= 4.69, S.D. = 0.05).
2. Students demonstrated an ability to evaluate and design scientific inquiry processes that exceeded the 70% criterion.
3. Students' satisfaction with project-based learning was at the highest level (= 4.89, S.D. = 0.31).
