Bringing the Laboratory into the Lecture: Use of Atomic Absorption Spectrometry Labs to Aid the Process

9452248 Stolzberg化学系正在开发多种方法来加强《普通化学导论》的实验室和课堂部分之间的联系。该计划的一个主要重点是提出了一系列的四个原子吸收光谱实验。在每个实验完成后，学生检查了其他组的数据并解释了他们的结果，他们建议分配一个完整的讲座时间，让学生展示他们对实验数据的解释。教师将总结学生的发现，并将其应用到实践中。这些实验的设计是为了让学生练习科学调查的组成部分。他们将使用精心设计的实验来比较平均值或趋势，使用归纳推理来检验假设，并检查和解释相对较大的数据集，将其简化为图形形式。此外，他们将做一些简短的实验外写作练习，这些练习将由他们的同龄人进行评估。他们的目的是使学生对良好的实验室科学的组成方法的概念感到舒适，并对其能力感到着迷。

9452248 Stolzberg The Department of Chemistry is developing multiple approaches to strengthen the connection between the laboratory and lecture portions of Introductory General Chemistry. A major focus of the plan is the proposed series of four atomic absorption spectrometry experiments. After each experiment is done, and students have examined data from other groups and interpreted their results, they propose that a full lecture period be allocated for students to make presentations of their interpretation of the experimental data. Faculty will summarize student findings and put them into a practical perspective. The experiments are designed so that the students will practice the component parts of scientific investigation. They will use well-designed experiments to make comparisons of averages or trends, test hypotheses using inductive reasoning, and examine and interpret relatively large data sets reduced to graphical form. In addition, they will do short, out-of lab writing exercises which will be evaluated by their peers. They intend to make students comfortable with the idea of, and enchanted with the ability of, the component methodologies of good laboratory science.
