With this proposal we intend to address student learning and attitude in our general chemistry course by incorporating computational tools for problem solving into weekly activity sessions. These activity sessions will include a flexible combination of wet-laboratory experimentation with computerized data collection as appropriate, data analysis, molecular modeling, and group problem solving. To facilitate this enhancement, we plan to equip our general chemistry laboratory with the modem computer tools of a chemist. The equipment will be used in the weekly small-group activity sessions, which are an integral part of our general chemistry course. The application of computational tools to chemical problems will be systematically introduced to students in sequential activities, which teach and ultimately integrate different methodologies for measuring, modeling, and understanding chemical phenomena.The specific equipment requested include a computer problem solving station for each pair of students that will consist of a low-cost computer, data acquisition hardware. Each computer will be loaded with software licensed by the college, including molecular modeling software. Additionally, computer projection equipment for the laboratory is requested.The primary focus of the curricular changes motivating this proposal is augmenting the participatory activities we offer students in order to improve their learning in general chemistry. Experiments will be improved by better and more efficient data collection followed by subsequent analysis. Learning and understanding will be enhanced by individual access to modeling software. By creating a classroom atmosphere that encourages engaged and cooperative inquiry, our proposed general chemistry activity sessions will not only improve students' learning but their perception of science as well.

有了这个建议，我们打算解决学生的学习和态度，在我们的普通化学课程，将计算工具解决问题，每周的活动会议。这些活动将包括湿实验室实验与计算机数据收集的灵活组合，数据分析，分子建模和小组问题解决。为配合这项改善工作，我们计划在化学实验室配备现代化的电脑工具。这些设备将用于每周的小组活动，这是我们的普通化学课程的一个组成部分。本课程将在连续的活动中系统地向学生介绍计算工具在化学问题中的应用，这些活动将教授并最终整合不同的测量、建模和理解化学现象的方法。要求的具体设备包括为每对学生提供的计算机问题解决站，包括一台低成本计算机和数据采集硬件。每台计算机将装载由学院许可的软件，包括分子建模软件。此外，计算机投影设备的实验室是必需的。课程变化的主要重点，激发这一建议是增加我们为学生提供的参与性活动，以提高他们在普通化学的学习。实验将通过更好和更有效的数据收集以及随后的分析来改进。学习和理解将通过个人访问建模软件得到加强。通过创造一个鼓励参与和合作探究的课堂氛围，我们建议的普通化学活动课程不仅可以提高学生的学习，还可以提高他们对科学的感知。
