Computing in Science Majors General Chemistry Laboratories Linked with a Laboratory Interfacing Course

这个项目将说明化学原理的实验与进行实验的新策略和新形式结合在一起。这一策略包括从让学生遵循详细说明的“传统”实验转变为让学生在进行实验和分析数据方面有更多自由的探究哲学。新的格式要求每个实验室站都有计算机进行数据收集、处理、分析和显示，并纳入了计算机化的实验。这种现代计算机技术和查询方法的结合，使学生从繁琐的数据收集中解脱出来，让学生参与到数据的观察、分析和解释中。普通化学实验室的变化与高级实验室接口课程的变化有关，该课程强调普通化学实验室用于数据采集的简单电路和传感器的结构和测试。此外，高级学生使用这些电路和传感器开发新的普通化学实验。当新的实验被纳入普通化学实验室时，它们将得到进一步的测试。这种共生关系为整个项目的持续反馈和评估提供了源泉。

This project incorporates experiments that illustrate chemical principles with a new strategy and a new format for conducting the experiments. The strategy involves switching from "traditional" experiments, in which students follow detailed directions, to an inquiry philosophy, in which students are given more freedom in conducting experiments and analyzing data. The new format requires computers at each laboratory station for data collection, manipulation, analysis, and display and incorporates computerized experiments. This merger of current computer technology and the inquiry approach frees the student from tedious data collection and engages students in the observations, analysis, and interpretation of data. The changes in the general chemistry laboratory are linked to changes in an advanced laboratory interfacing course that emphasizes the construction and testing of simple circuits and sensors used for data acquisition in the general chemistry laboratory. Additionally, the advanced students develop new general chemistry experiments using these circuits and sensors. The new experiments are further tested when they are incorporated into the general chemistry laboratory. This symbiotic relationship provides a source for continual feedback and evaluation of the entire project.
