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州立大学工程学院和教育学院的承诺，以加强未来数学和科学K-12教师的本科准备。 通过这个概念验证项目，调查模块，涉及WWW控制的环境扫描电子显微镜（SEM）的开发和纳入三门课程的职前小学和中学教师，展示WWW控制的科学内容整合到现有的教师教育课程。 这些模块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法和内容知识。 材料失效分析和生物体结构领域的两个试点模块包含一个问题设置视频，一个调查工作簿，一套材料和补充SEM图像可在WWW主页上。 该项目补充了爱荷华州国家协作卓越的教师准备（ISCEPT）和数学工程网络与教师的真实的科学（MENTOS）活动。

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.
