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.

三个入门化学实验室正在配备包含海洋光学CCD光谱仪，服务器和网络硬件的工作站。光谱仪，结合数据收集和数据处理的能力，正在一系列新的完全网络集成的探究实验室中使用，通过这些实验室，学生们正在确定和体验1）物质与光之间相互作用的性质，2）浓度与吸收率之间的关系，3）平衡和推测的概念，反应速率的性质及其与反应物浓度的关系。 该项目正在使合作学习和探究式方法适应这些实验室，并正在使标准实验适应新设备和教学方法的使用。
