Science Education: A Process Approach to Studying Toxic Substances and Their Effects on Human Health

“科学教育：有毒物质及其对人类健康影响的过程研究”是一项综合了基础科学概念、相关技术、风险评估和科学过程方法的跨学科教师培养项目。每年夏天，来自加利福尼亚和邻近各州的30名不同的高中教师将参加一个为期两周的课程，内容是有毒物质的化学和生物学、有害物质的适当管理以及与人类健康有关的问题。内容讲座和各种讨论环节将由个人和小组实验室练习，以及计划到垃圾场、污水处理厂、危险废物设施（劳伦斯利弗莫尔）和研究实验室分析和调查有毒物质的管理方法的实地考察来补充。参与者将被期望将概念和活动纳入他们的课堂课程，特别强调程序中强调的过程方法。学年期间的后续会议不仅将促进教师之间的信息和经验交流，而且还将为项目工作人员提供一个机会，评估该方案在及时将有毒物质与人类健康这一主题引入高中科学课程方面的有效性。

Science Education: A Process Approach to Studying Toxic Substances and Their Effects on Human Health is a cross- discipline teacher enhancement project which integrates basic science concepts, related technology, risk assessment, and science processes methodology. In each of three summerrs,a different group of thirty high school teachers from California and contiguous states will participate in a two- week program structured on the chemistry and biology of toxic substances, proper management of hazardous materials, and related concerns of human health. Content lectures and varied discussion sessions will be complemented by individual and group laboratory exercises as well as planned field trips to a dump site, a sewage treatment plant, a hazartdous waste facility (Lawrence Livermore), and research laboratories analyzing and investigating management methods of toxic substances. Participants will be expected to incorporate the concepts of and activties into their classroom curriculum with special emphasis on the process approach emphasized in the program. Follow-up sessions during the school year will not only facilitate an exchange of information and experiences among the teachers, but will also provide an opportunity for the project staff to evaluate the effectivenesss of the program in introducing the timely subject of toxic substances and human health into high school science courses.
