Incorporation of Instrumentation into an Innovative Introductory Chemistry Laboratory Curriculum

化学（12）无论是在课堂上还是在实验室里，我们的普通化学课程最近的变化旨在使学生从定量的、算法的问题解决转向基于概念的问题解决。标准的授课形式辅以以学生为中心的项目，这些项目在课堂上解决。为了配合课程课堂部分的这些变化，实验室部分已经全面改造，包括以发现为基础的实验，学生通过练习来学习，帮助他们自己发现重要的科学原理。学生首先在这种类型的实验室环境中学习一个概念，然后他们将所学到的知识应用于解决现实生活中感兴趣的问题。由其他人开发并在化学教育文献中报道的实验正在被改编以创造这种新的实验室体验。这个项目通过让学生接触到比以前的实验课程更多的仪器来帮助实现这些目标。此外，学生们在更大程度上使用计算机，无论是分子建模还是数据处理。与修订后的课程和实验室形式相结合，该项目还纳入了额外的仪器，包括紫外-可见光谱仪、原子吸附光谱仪、红外光谱仪和两个气相色谱仪，以及计算机和软件。

Chemistry (12) Recent changes in our General Chemistry curriculum are designed to move students away from quantitative, algorithmic problem solving to concept-based problem solving, both in the classroom and the laboratory. The standard lecture format has been supplemented by student-oriented projects which are solved during the classroom period. To coincide with these changes in the classroom part of the course, the laboratory portion has been totally revamped to include discovery-based experiments, in which students learn by performing exercises that help them discover important scientific principles on their own. The students first learn about a concept in this type of laboratory setting, and they then apply their acquired knowledge to solve a problem of interest in real life. Experiments developed by others and reported in the chemical education literature are being adapted to create this new laboratory experience. This project is helping to accomplish these goals by exposing the students to more instrumentation than in the previous laboratory curriculum. In addition, students are using computers to a greater extent, both for molecular modeling as well as data manipulation. In conjunction with the revised course and laboratory format, this project is also incorporating additional instrumentation, including UV-Vis spectrometers, an atomic adsorption spectrometer, an IR spectrometer, and two gas chromatographs, along with computers and software.
