Laser Applications in Science Education (Lase): Phase 2

LASE项目以创新的“自己动手”光学实验课程为中心，以操作和调制激光束的原理为基础，旨在通过向学生介绍日常激光应用，使物理对高中生更具吸引力。为了促进这些想法的实施，1991年期间将举办两次为期两周的夏季讲习班，培训40名高中物理教师在下一学年在在职帮助下教授这门课程。该项目集中在项目第一阶段形成的三个强有力的教学理念：1。1 .为每个参与者提供一个光学系统，以便在任何设备简陋的车间中轻松复制或修改，并结合许多“现成的”硬件商店物品（一个原型已经被竞争）；在参与者同时进行同一项活动时，预先为他们提供一系列的逐站指导。这是一个共同的光学系统的优势。在1991-92学年期间，所有参与者都作为同伴教师参与该计划的服务阶段。在这段时间里，每组五名教师将负责每月的会议。学生将帮助他们。来自第一阶段的10名教师将与圣何塞州立大学的教师一起在夏季研讨会上提供指导。协助将由一名全职技术员和上海大学物理专业的学生提供。40名参加者将于年内至少带一名客座教师参加至少一次在职会议。这将是正式要求。到今年年底，将有近70名教师积极参与。费用分摊相当于国家科学基金会奖金的48%。

The LASE project is centered on an innovative "do-it- yourself" optics laboratory course based on the principles of manipulating and modulating laser beams, and designed to make physics more attractive to high school students by introducing them to every-day laser applications. To facilitate implementation of these ideas, 2 two-week Summer workshops will be provided during 1991 to train forty high school physics teachers to teach the course, with in- service help, the following academic year. The project concentrates on three strong pedagogical ideas developed during the first phase of the project: 1. providing each participant with an optical system designed to be easily reproduced or modified in any modestly equipped workshop, and incorporating many "off-the-shelf" hardware-store items (A prototype has already been competed), 2. providing a series of station-by-station instructions beforehand for the participants as they all work on the same activity at the same time. This is the advantage of having a common optical system, 3. involving all participants as peer teachers during the 1991-92 academic year in-service phase of the program. Groups of five teachers will take charge of each of the monthly meetings scheduled for that period. Students will help them. Ten teachers from Phase 1 will provide instruction during the Summer workshops, along with faculty from San Jose State University. Assistance will be provided by a full-time technician and SJSU physics majors. The forty participants will bring along at least one guest teacher to at least one in-service meeting during the year. This will be formally required. By year's end close to seventy teachers will have been actively involved. Cost sharing equals 48% of the NSF award.
