| Summary: | 碩士 === 國立中央大學 === 環境工程研究所在職專班 === 104 === In this study, the third-grade students were tested by questionnaire and statistical methods on their changes of environmental knowledge, behavior, and attitudes by an on-site ecological teaching approach. An ecological pond was located on the campus of the researcher’s school, which enabled the set-up of an aquaponics in it as an on-site ecological teaching apparatus for comparing environmental teaching proficiency of participating (experimental) and non-participating (control) groups. The questionnaire was revised by scholars and experts from the original version and was pre-tested by a total of 60 students in the third- and fourth-grade students of the same school. The questionnaire was then finalized by statistical reliability test. After the accomplishment of on-site aquaponics ecological teaching for the experimental group, the scores of environmental knowledge in the pre- and post-tests were significantly increased (4.24 vs. 8.00, p<0.05 for t-test). In addition, the scores of environmental behavior and attitudes were also increased significantly in the pre- and post-tests (18.8 vs. 23.2, p<0.05 for t-test and 13.0 vs. 18.72, p<0.05 for t-test), respectively. In contrast, the control group was taught regular integrative-activity subjects, the scores of the control group of environmental knowledge and behavior in the pre- and post-tests were not significantly increased (4.11 vs. 3.67, p>0.05 for t-test and 19.3 vs. 18.0, p>0.05 for t-test). However, the scores of environmental attitudes were increased significantly in the pre- and post-tests (11.7 vs. 16.9, p<0.05 for t-test). According to the test results, the on-site aquaponics ecological teaching is more effective in enhancing environmental consciousness than the regular integrative-activity subject teaching for the third-grade students.
