Scanning Electron Microscopy Applications for Community College Science Instruction

全自动扫描电子显微镜的加入， 北亨内平大学的本科生生物实验室 社区学院（NHCC）将使科学水平成为可能 在此之前，在较低级别的教学中， 只为高年级学生和研究生保留使用 一台老式的手动扫描电子显微镜（SEM）， 一个试点项目，为较低级别的部门提供SEM应用程序 大学生已经证明，SEM实验室的经验， 激发对科学的兴趣和理解 科目 一个完全自动化的，用户友好的SEM将允许 生物系将进行以下更改：（1）A 新课程侧重于结构生物学技术， 包括一个学生研究组件将被添加;（2） 学习细胞和分子生物学的学生将提高 在细胞检测和 组织结构;（3）所有生物学入门学生将 有机会亲自操作SEM -The 经验本身和显微照片将补充 用于研究的其他实验室和讲座材料 复杂的结构;（4）实验室演示， 探访中学生及提供机会， 通过访问大学和中学的研究项目 教育工作者将增加。

The addition of fully automated scanning electron microscopy to the undergraduate biology laboratories at North Hennepin Community College (NHCC) will make possible a level of science instruction at the lower-division that was, before this time, reserved only for upper-division and graduate students. Using an older, manually operated Scanning Electron Microscope(SEM), a pilot project with SEM applications for lower-division college students has demonstrated that SEM lab experiences generate a greater interest in and understanding of science subjects. A fully automated, user friendly SEM will permit the following changes to be made in the Biology Department: (1) A new course focusing on techniques in structual biology that includes a student research componen will be added; (2) students studying cell and molecular biology will have enhanced hands-on lab experience in the examination of cellular and tissue structure; (3) all students in introductory biology will have an opportunity for firsthand operation of a SEM -The experience itself and the micrographs produced will supplement other laboratory and lecture materials used for the study of intricate structures; and (4) laboratory demonstrations for visiting secondary school students and opportunities for research projects by visiting college and secondary school educators will increase.
