Computer controlled data acquisition and analysis systems have been integrated into the introductory laboratories for both science and non-science majors. These laboratories are associated with General Chemistry, Equilibrium and Analysis, Accelerated General Chemistry, Accelerated General Chemistry Laboratory, and Perspectives in Environmental Chemistry. These five courses service all chemistry, biochemistry, biology, and pre-health-science, and environmental studies students as well as students not majoring in the sciences. More than 250 students use this equipment annually. In these courses, Students perform experiments that require significant amounts of data to be collected, processed, analyzed, and interpreted . This project focuses on the interpretation and analysis of observations rather on data collection. Examples of the many experiments that use the new data collection systems are determination of the heats of reaction in solutions, of heat capacities of metals, and of the order of reactions from kinetic measurements. Also, the new equipment permits simultaneous measurements that allows two or three concepts to be integrated into a single experiment.

计算机控制的数据采集和分析系统已被整合到理科和非理科专业的入门实验室中。这些实验室与普通化学、平衡与分析、加速普通化学、加速普通化学实验室和环境化学展望有关。这五门课程服务于所有化学、生物化学、生物学、健康预科和环境研究专业的学生以及非理科专业的学生。每年有超过250名学生使用这种设备。在这些课程中，学生进行的实验需要收集、处理、分析和解释大量的数据。该项目侧重于对观察结果的解释和分析，而不是数据收集。使用新数据收集系统的许多实验的例子是通过动力学测量确定溶液中的反应热、金属的热容和反应级数。此外，新设备允许同时进行测量，允许将两个或三个概念整合到一个实验中。
