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.

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抽象，并阻止学生充分理解它们。 使用扫描电子显微镜（SEM）的实践经验可以使这些信息更加具体。 为了提供这种经验，学院正在购买SEM和配套设备，用于科学课程。 该项目使科学教师提供有效的，创新的实验室经验，大一和大二的科学学生。 理科学生可以在现有课程中使用这种技术，教师可以制作教学材料供课堂使用。 该方案还用于为需要在职培训或希望职业发展的当地中学理科教师举办讲习班。
