Electronic Measurement Network for the Freshman Chemistry Laboratory

本项目在理工科新生化学实验课程中，通过构建和实施测量网络，介绍电子测量和数据处理。其结果是利用网络的能力对实验课程进行了重大修订。它提供的连通性促进了合作学习活动。学生学习小组以真正的团队模式运作，在实验测量中分享他们的努力，最重要的是，在实验室中对数据进行初步解释。偶尔可以进行多届会议项目，其中学习小组的成员研究问题的有关方面，并将他们的努力结合起来，以产生更有意义的结果和结论。通过具体的例子，学生们了解到今天的化学家们通过电子方式进行测量和数据操作，作为团队成员在扩展项目中合作，并花费大量时间解释数据。一个小型的原型网络系统已被构建和学生测试。这个项目将完成这个原型的设计，并在实验室中建造和安装它，同时修订实验室课程。该系统的安装和实施分阶段进行，为期一年，可以直接比较有网络和没有网络的学生学习情况。这可以通过普通的实验室检查来评估。实验室项目的客户正在被仔细监控，并通过定期调查评估他们的态度和看法。

This project introduces electronic measurement and manipulation of data through the construction and implementation of a measurement network in freshman chemistry laboratory programs for science and engineering majors. The result is a major revision of the laboratory curriculum that takes advantage of the capabilities of the network. The connectivity it provides facilitates cooperative learning activities. Learning groups of students function in a true team mode, sharing their efforts in experimental measurement and, most significantly, in the preliminary interpretation of data while still in the laboratory. Occasional multi-session projects can be undertaken, in which the members of learning groups study related aspects of a problem and combine their efforts to produce more meaningful results and conclusions. The students learn, through concrete examples, that today's chemists carry out measurements and data manipulation electronically, work cooperatively on extended projects as members of a team, and spend a great deal of time interpreting data. A small prototype network system has been constructed and tested with students. This project will finalize the design of this prototype and construct and install it in the laboratories, concurrent with revision of the laboratory curriculum. Installation and implementation of the system in stages over a 1-year period allows direct comparison of student learning with and without the network. This can be assessed through common laboratory examinations. The clientele in the laboratory program are being carefully monitored and their attitudes and perceptions assessed through regular surveys.
