Improvement of Science Instruction Through Use of a Scanning Electron Microscope

虽然扫描电子显微镜在科学教科书中很常见，但大多数学生仅限于在实验室练习中使用光学显微镜。这使得这些文本参考文献变得抽象，阻碍了学生对它们的充分理解。使用扫描电子显微镜（SEM）的实际操作经验可以使这些信息更加具体。为了提供这种体验，学院正在购买一台电子显微镜和配套设备用于科学课程。这个项目使科学教师能够为大一和大二的理科生提供有效的、创新的实验室体验。理科生可以在现有的课程中使用这项技术，教师可以制作课堂上使用的教学材料。管理学院也被用来为需要在职培训或渴望专业发展的本地中学科学教师提供讲习班。

While scanning electron micrographs are common in science textbooks, most students are limited to using light microscopes in laboratory exercises. This makes these text references abstract and prevents students from understanding them fully. Hands-on experience with a scanning electron microscope (SEM) can make this information more concrete. In order to provide this experience, the college is buying an SEM and supporting equipment for use in the science curriculum. This project enables science instructors to offer effective, innovative laboratory experiences to freshman and sophomore science students. Science students can use this technology in the existing curriculum, and instructors can produce instruction materials for use in their classes. The SEM is also be used to offer workshops for local secondary science teachers who need in-service training or who desire professional growth.
