A Survey of Science Teachers, Perception and Attitudes on Disposal of School Laboratory Waste Water and Materials

환경 오염 및 과학 실험실 폐수와 폐기물 처리에 대한 과학 교사들의 인식과 태도 조사

The purpose of this study was to survey science teachers, perception and attitudes on disposal of school laboratory waste water and materials. To fulfill this aim, a questionnaire was administered to 244 secondary school science teachers. The result of this study revealed that there was no large disparity in the degree of understanding of laboratory waste disposal and the laboratory waste water treatment, and in secondary science teachers' perception and practicing attitude on the environment. While science teachers had deep understanding of laboratory waste disposal and its influence on environmental pollution, they expressed less positive attitude toward the actual disposal of waste materials and waste water, and participation in teacher training. Therefore, it is necessary to provide standards of systematized disposal methods and proper disposal facilities in middle and high school laboratories, as well as to investigate teachers' needs before providing teacher training program.
