Students have great difficulty making the conceptual transition from the macrocopic to the microscopic world. We propose to develop and disseminate a collection of materials to introduce a revolutionary teaching microscope, the video-probe microscope, into introductory college science classrooms to help students make this transition. The efficiency and dramatic effect of this instrument was demonstrated in a previous, pilot LaSER Grant, Exploring Microstructures: Introducing Biology Students and Teachers to Images, Tools and Applications of High-Tech Microscopy NSF/LaSER (1991) . This technologically advanced microscope consists of a tiny, hand-held, self-illuminated video camera with interchangeable magnifying lenses attached by a hybrid fiber optic/electronic cable to a controller box which in turn connects to a television monitor. By touching the tip of the lens to any object under scrutiny, a user of any age or ability immediately produces a well-lighted, in-focus image of the appropriate magnification on a regular television monitor. This tool will be invaluable in stimulating investigation in our undergraduate biology and earth science laboratories, particularly for non-science majors. Video recordings can be made in the normal fashion.

学生很难从宏观世界到微观世界进行概念转变。我们建议开发和传播一系列材料，将革命性的教学显微镜（视频探针显微镜）引入大学科学入门课堂，帮助学生实现这一转变。该仪器的效率和显着效果在之前的试点 LaSER 资助项目“探索微观结构：向生物学学生和教师介绍高科技显微镜的图像、工具和应用” NSF/LaSER (1991) 中得到了证明。这种技术先进的显微镜由一个微型手持式自发光摄像机组成，摄像机带有可互换的放大镜，通过混合光纤/电缆连接到控制箱，控制箱又连接到电视监视器。通过将镜头尖端接触到任何被观察的物体，任何年龄或能力的用户都会立即在常规电视监视器上产生适当放大倍数的明亮、清晰的图像。该工具对于刺激我们本科生生物学和地球科学实验室的调查非常有价值，特别是对于非科学专业的学生。可以按照正常方式进行视频录制。
