Incorporating Inquiry-Based Science Modules Involving an Environmental Scanning Electron Microscope into Preservice Teacher Education Classes

该项目建立在爱荷华州立大学工程学院和教育学院致力于加强对未来数学和科学K-12教师的本科生准备的基础上。通过这一概念验证项目，开发了涉及WWW控制的环境扫描电子显微镜(SEM)的探究模块，并将其纳入中小学教师职前培训的三门课程，展示了WWW控制的科学内容与现有教师教育课程的整合。这些单元支持通过探究概念进行学习，并符合国家科学教育标准，以提高职前教师的科学教学和教学知识。在生物体的材料和结构失效分析领域的两个试点模块包括一个问题解决视频、一个查询练习册、一个材料工具包和WWW主页上的补充扫描电子显微镜图像。该项目是对爱荷华州卓越教师培训合作(ISCEPT)和数学工程与真正科学教师网络(MENTORS)活动的补充。

This project builds on the commitment of Iowa State University's College of Engineering and College of Education to the enhancement of the undergraduate preparation of future mathematics and science K-12 teachers. Through this Proof-of-Concept project, inquiry modules involving the WWW-controlled environmental scanning electron microscope (SEM) are developed and incorporated into three courses for pre-service elementary and secondary teachers, demonstrating the integration of WWW-controlled science content into existing teacher education courses. The modules support the learning through inquiry concepts and are consistent with the National Science Education Standards to improve the science pedagogical and content knowledge of pre-service teachers. The two pilot modules in the areas of Failure Analysis of Materials and Structure of Organisms contain a problem-setting video, an inquiry workbook, a kit of materials, and supplementary SEM images available on the WWW homepage. The project complements the Iowa State Collaborative for Excellence in Teacher Preparation (ISCEPT) and the Mathematical Engineering Networking with Teachers of Real Science (MENTORS) activities.
