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

该项目采用了一种新的策略和一种新的实验形式来说明化学原理。 该策略涉及从“传统”实验（学生遵循详细的指导）转向探究哲学（学生在进行实验和分析数据时有更多自由）。 新的格式要求在每个实验室站的计算机数据收集，操作，分析和显示，并纳入计算机化的实验。 当前计算机技术和探究方法的这种合并使学生从繁琐的数据收集中解脱出来，并使学生参与数据的观察，分析和解释。 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，该课程强调在普通化学实验室中用于数据采集的简单电路和传感器的构建和测试。 此外，先进的学生开发新的一般化学实验使用这些电路和传感器。 新的实验在被纳入普通化学实验室时得到了进一步的测试。 这种共生关系为整个项目的持续反馈和评估提供了一个来源。

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.
