การพัฒนาชุดกิจกรรมวิทยาศาสตร์ตามแนวทางสะเต็มศึกษา (STEM EDUCATION) เรื่อง การปรับปรุงคุณภาพน้ำสำหรับนักเรียนระดับมัธยมศึกษาตอนต้น A DEVELOPMENT OF THE SCIENCE ACTIVITY PACKAGE USING STEM EDUCATION APPROACH ON WATER TREATMENT FOR LOWER SECONDARY STUDENTS

Abstract

            The purposes of this study were 1) to develop the science activity packages based on STEM Education on water treatment for lower secondary students and to assess the quality of the packages by experts, 2) to study the students’ learning outcomes, and 3) to study the students’ satisfaction toward learning with the science activity packages on water treatment. The participants of this study were the lower secondary students (n=21) of Nampood School, Trang province by purposive sampling. The research tools consisted of: 1) the science activity packages based on STEM Education on water treatment for lower secondary students, 2) the assessment form of the quality of the science activity packages by experts, 3) the learning achievement tests, and 4) the students satisfaction questionnaire toward learning the science activity packages. The result indicated that: 1) the science activity packages consisted of 3 activities: activity 1: exploring water quality, activity 2: designing and creating of water treatment model, and activity 3: testing the effectiveness of the model. The quality of the science activity packages by experts was at level of good quality, 2) the students’ learning achievement was mean scores at 74.49%, which was higher than 70% of criteria at the statistically significant .05 level, and 3) the students’ satisfaction towards learning with the science activity packages was at very good level
