Clarifying Concepts of Concentration , Equilibrium and Reaction Rate in Introductory Chemistry Using Visible Spectroscopy

三个初级化学实验室正在配备工作站，其中包括海洋光学公司的CCD光谱仪、服务器和联网硬件。光谱仪与数据收集和处理能力一起被用于一系列新的完全网络集成的询问实验室，通过这些实验室，学生将确定和体验1)物质和光之间相互作用的性质，2)浓度和吸光度之间的关系，3)平衡和推测的概念，以及4)反应速率的性质及其与反应物浓度的关系。该项目正在将合作学习和基于探究的方法引入这些实验室，并正在调整标准实验，以利用新的设备和教学方法。

Three introductory chemistry laboratories are being equipped with workstations containing Ocean Optics CCD spectrometers, servers, and networking hardware. The spectrometers, in conjunction with capabilities for data collection and manipulation of data, are being employed in a series of new fully network-integrated inquiry laboratories through which students are determining and experiencing 1) the nature of interactions between matter and light, 2) the relationship between concentration and absorbance, 3) the concept of equilibrium and speculation, and 4) the nature of reaction rate and its relationship to reactant concentration. The project is adapting cooperative learning and an inquiry-based approach into these laboratories, and is adapting standard experiments to make use of the new equipment and pedagogical approaches.
