Electronic Measurement Network for the Freshman Chemistry Laboratory

本项目通过构建和实施理工科大学一年级化学实验项目中的测量网络，介绍了电子测量和数据处理。结果是对实验课程进行了重大修订，充分利用了网络的功能。它提供的连接促进了合作学习活动。学生的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，当他们还在实验室时，分享他们对数据的初步解释。可以偶尔进行多个会议的项目，学习小组的成员研究一个问题的相关方面，并共同努力产生更有意义的结果和结论。学生们通过具体的例子了解到，今天的化学家通过电子手段进行测量和数据处理，作为团队成员合作开展更广泛的项目，并花费大量时间解释数据。构建了一个小型原型网络系统，并在学生中进行了测试。该项目将最终确定这一原型的设计，并在修订实验室课程的同时，在实验室中建造和安装。在一年的时间内分阶段安装和实施该系统，可以直接比较学生在有网络和没有网络的情况下学习情况。这可以通过常见的实验室检查进行评估。实验室项目中的客户正在接受仔细的监测，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.
