Extended Classroom for Enhanced Learning (EXCEL)

爱荷华州立大学(ISU)课程与教学部和材料科学与工程系的教职员工正在建立一个教学计划和一个教室，致力于将扫描电子显微镜(SEM)的能力带入中小学课堂。这个项目的目标是增进学生和教师对他们周围微观世界的理解和学习。随着互联网和远程控制的中小企业的发展，现在有一个独特的机会，可以帮助儿童通过廉价的互联网连接获得极其昂贵的技术先进的设备。教室将由一个完全连接到万维网和互联网的环境扫描电子显微镜组成。将举办一项由中小学在职和入职前教师参加的暑期培训计划，指导他们如何在课堂上使用结构方程。教师将开发课程，其内容和SEM访问将根据年级水平的不同而有所不同。课堂教师将通过一系列暑期工作坊接受有关结构方程的使用和能力的指导。在学年期间，专攻科学和数学的职前中小学教师将协助课堂调查。

Faculty members in the Department of Curriculum and Instruction and the Department of Materials Science and Engineering at Iowa State University (ISU) are establishing an instructional program and a classroom dedicated to bringing the capabilities of the scanning electron microscope (SEM) into elementary and secondary classrooms. The goal of this program is to enhance student and teacher understanding and learning of the microscopic world around them. With the development of the Internet and remote-controlled SEMs, a unique opportunity now exists to facilitate children's access to extremely expensive, technologically advanced equipment via inexpensive Internet connections. The classroom will consist of an environmental SEM fully connected to the World Wide Web and the Internet. A summer training program involving present and pre-service teachers at the elementary and secondary levels will be conducted, instructing them on how to use the SEM in the classroom. Teachers will develop the lessons, which will vary in content and SEM access, depending upon grade level. Classroom teachers will receive instruction in the SEM's use and capabilities through a series of summer workshops. During the school year, pre-service elementary and secondary teachers who are specializing in science and mathematics will facilitate the classroom investigations.
