Instrumentation for a Guided Discovery Approach to General Chemistry

在两个学期的实验室序列学生被引导重新发现化学的基本原理。而不是第一次学习理论的讲座和验证的原则，在实验室，学生进行实验室观察和情况下，每个学生在略有不同的条件下进行实验，并将课堂结果输入到PC，绘图和显示的讲师。学生作为一个小组参与结果的讨论，在某些情况下，能够立即返回实验室，并测试他们的假设的预测能力。现代化的快速扫描光谱仪和色谱仪是探索实验室流程的核心特征。这使得大量的学生发现的概念，通常不会考虑在一般的化学实验室。此外，通过使用这种现代仪器，某些经典的普通化学实验变得更加有效，从而使学生能够在一个时期内收集更多的数据，从而最大限度地增加可用的数据量，并为小组讨论趋势留出时间。该机构正在将NSF的赠款与等量的资金相匹配。

In a two-semester laboratory sequence students are guided to rediscover the basic principles of chemistry. Instead of first learning theories in lecture and verifying the principles in the laboratory, students make laboratory observations and cases each student preforms experiments under slightly different conditions and the class results are entered into a PC, graphed and displayed by the instructor. Students participate as a group in the discussion of the results and in some cases are able to return immediately to the laboratory and test the predictive power of their hypotheses. Modern, rapid-scanning spectrometers and chromatographs are a central feature of the discovery laboratory process. These allow large numbers of students to discover concepts which are usually not considered in the general chemistry laboratory. In addition, certain classical general chemistry experiments are made more efficient through use of this modern instrumentation thus making it possible for students to gather more data in a single period thereby maximizing the amount of data available and still leaving time for group discussions of the trends. The institution is matching the NSF grant with an equal amount of funds.
