Electronic Teacher Guide: Its Development and Use in Supporting Educative Curricula

科学教育中心和教育发展中心的儿童与技术中心正在开发和测试一个原型电子教师指南，用于NSF资助的课程中为期12周的遗传学单元，名为基础科学：生物学（0439443），以确定它如何影响高中教师的学习和实践。电子指南是以现有的印刷指南为基础，设计灵活，可以预见和满足不同知识/技能的教师在课程规划和支持方面的需要。电子指南为教师提供了及时的、使用点的资源访问，帮助教师计划、实施和反思创新的改革导向的教学材料。案例研究将调查如何使用指南改变教师的学科知识，教师的教学内容知识的科学内容和科学探究，教师的课堂实践，和学生的参与。本研究的结果将有助于确定灵活的模块化电子教师指南在多大程度上影响教师实践，以及在多大程度上提高教师有效实施课程的能力。

The Center for Science Education and the Center for Children and Technology at the Education Development Center are developing and testing a prototype electronic teacher's guide for a 12-week genetics unit in the NSF-funded curriculum titled Foundation Science: Biology (0439443) to determine how it impacts high school teachers' learning and practice. The electronic guide, which is based on an existing print guide, has a flexible design so that it anticipates and meets the curriculum planning and support needs of teachers with different knowledge/skills profiles. The electronic guide provides teachers with just-in-time, point-of-use access to resources that help teachers plan, implement, and reflect on innovative reform-oriented instructional materials. Case-study research will investigate how use of the guide changes teachers' subject-matter knowledge, teachers' pedagogical content knowledge for science content and science inquiry, teachers' classroom practices, and student engagement. The results of this project will help to determine to what extent a flexible and modular electronic teacher guide can afffect teacher practice and to what extent it can enhance the ability of teachers to implement curricula effectively.
