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.

本计画透过在理工科新生化学实验课程中建构与实施一个量测网路，介绍电子量测与资料处理。其结果是对利用网络能力的实验室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，分享他们在实验测量方面的努力，最重要的是，在实验室中对数据进行初步解释。可以偶尔进行多期项目，学习小组的成员研究一个问题的相关方面，并联合收割机共同努力产生更有意义的结果和结论。学生通过具体的例子了解到，今天的化学家以电子方式进行测量和数据处理，作为团队成员在扩展项目上合作，并花费大量时间解释数据。 一个小型的原型网络系统已经建成，并与学生进行了测试。该项目将最后确定这一原型的设计，并在实验室建造和安装，同时修订实验室课程。在一年的时间内分阶段安装和实施该系统，可以直接比较有网络和没有网络的学生的学习情况。这可以通过普通的实验室检查来评估。正在对实验室方案的客户进行认真监测，并通过定期调查评估他们的态度和看法。
