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.

化学（12）我们的普通化学课程的最新变化旨在使学生从定量，算法问题解决到基于概念的问题解决，无论是在教室还是实验室。 标准的讲座形式已被补充以学生为导向的项目，在课堂期间解决。 为了配合课程课堂部分的这些变化，实验室部分已经完全改造，包括基于发现的实验，学生通过练习来学习，帮助他们自己发现重要的科学原理。 学生们首先在这种实验室环境中学习一个概念，然后运用所学知识解决真实的生活中感兴趣的问题。 其他人开发的实验和化学教育文献中报道的实验正在适应创造这种新的实验室体验。 这个项目是通过让学生接触到比以前的实验室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。结合修订的课程和实验室格式，本项目还将纳入额外的仪器，包括紫外-可见光谱仪，原子吸收光谱仪，红外光谱仪和两个气相色谱仪，沿着计算机和软件。
