Teaching Environmental Education Using Song - Based Learning to Enhance Environmental Knowledge, Attitudes, and Ethics for Primary School Students

The environmental problems are important. Environmental education is used to solve them. It helps students have to knowledge, attitudes, and ethics. The purposes were to develop an environmental education lesson plan using Song-Based Learning (SBL) to be effective and efficient according to the specified criteria, to study knowledge, attitudes, and ethics using songs-based learning on pre-test and post-test, and of students with different genders. The sample used in this research consisted of 39 students from class 6/4 at Anubanmuang-atsamat school, Atsamat district, Roi Et province, being selected using simple random sampling. The research tools included an environmental education lesson plan using SBL, an environmental knowledge test, an environmental attitudes test, and an environmental ethics test. The statistics used in data analysis were frequency, percentage, mean, and standard deviation, Item-Objective Congruence (IOC), reliability index, discrimination index, difficulty index, process efficiency index (E1), outcome efficiency index (E2), and effectiveness index (E.I.), and Paired t-test, F-test (One-Way Multivariate Analysis of Variance) statistically significant at the level of .05. The research showed that 1) The environmental education lesson plan using SBL was an effectiveness score of 90.60/86.92, meeting the criteria, an effectiveness index (E.I.) of 0.6328. This indicates that students' knowledge increased and that the plan resulted in a 63.28% improvement in learning after its implementation. 2) After the lesson, students' average scores on environmental knowledge, attitudes, and ethics were significantly higher than before the lesson statically significant at the level of .05. 3) There were differences of environmental knowledge scores of students of different genders statistically significant at the level of .05., but no differences in environmental attitudes and ethics between students of different genders.
