Experimental evaluation of an environmental science curriculum and its effects on Texas secondary school students' environmental knowledge and attitudes

The objectives of this research project were to: (1) Develop an environmental science curriculum for secondary students that was primarily activity-based; and (2) test student knowledge and attitude changes resulting from exposure to this ten-day curriculum unit. The curriculum developed entitled Agriscience 384: Environmental Technology-Unit A, "Natural State of the Environment" was designed to provide an introduction to biological processes and basic principles of ecology, and to set the foundation for additional environmental studies. The curriculum was sent to 18 high schools in Texas and tested on 475 students. Students participating in this study were administered a pre-test and/or a post-test prior to participation and upon completion of the curriculum. The questionnaire included an attitude inventory and knowledge section as well as a biographical information section.; Results examine changes in environmental knowledge and environmental attitudes as well as the relationship between the two. Exposure to the environmental curriculum did appear to produce a more positive environmental attitude. In addition, an increase in environmental knowledge following exposure to the curriculum was demonstrated. Finally, this research found a strong correlation between environmental knowledge and environmental attitude.
