Ouantitative approach is used and subject-specific outcome is focused. A multiple choice test is developed in order to have subject-specific outcome. The test is carried out as prestest, posttest, and after 6 month as postpost test. It is found that the ecology-based environmental education programme is effective on gainig environmental knowledge in the short term as high level. On the other hand the programme is also effective at the middle level knowledge gaining in terms of population ecology and the total score of the test in the long term.
