A Quasi-experimental design was used to study the differences of students’ environmental concept, attitude, behavior and their attitude toward STS teaching. The research objects were four classes of 4th-grade school children. STS teaching strategy was used in one group and traditional teaching strategy was used in another group. The findings and conclusions were listed below: 1. Different environmental education experience of students had no apparent effect on their environmental concept, attitude or behavior. 2. Different sex of students had no apparent effect on their environmental concept or attitude, but girls were superior than boys in environmental behavior. 3. Before the administration of the course, students’ environmental attitude was related to their environmental behavior. After the course, there was a positive relationship between the students’ environmental concept and their environmental attitude. 4. After the practice of different instructions, both STS and traditional teaching group had a significant increase in environmental concept and behavior. But there was no significant difference in students’ environmental attitude after both teachings. We found that the STS group students showed a better learning effect than the tradition group students in the topic of ‘‘greenhouse effect defence’’, and the tradition group students had high scores than the STS group students in the topic of ‘‘greenhouse gas’’. 5. STS group students said that they had very good experiences in learning environmental knowledge. Finally, some recommendations were made: To enhance environmental education, teacher should provide better environmental education resources for students. They should also use important environmental issue to design curriculum. Continuing research could conduct research on environmental education learning processes and survey among different ages.
