Strategy To Improve Laboratory Instructions In First Year Chemistry Courses

9351679 May这个项目将改进化学课程，将最先进的计算机控制的分析仪器纳入实验室建设，指导一年级化学学生。选择符合这些标准的三种工具包括：计算机控制的二极管阵列，分光光度计，气相色谱仪，液相色谱仪，以及与色谱仪一起用于实验室的个人计算机。化学一年级的实验将被重新设计，30%的现有习题将被淘汰，40%的现有实验将增加购买的仪器，其余的实验将是新的，并基于仪器的应用，用现代化学实验室的程序来说明课程材料。学生将受益于这个项目在几个方面，包括；（一）实验所的工作能提高学生对化学的热情和兴趣；(b)他们将及早开始接受合格化学家或研究生所需的实验室技术培训；(c)实验工作将更有效地说明讲课材料；(d)他们将有机会参与设计他们自己的实验。＊＊＊

9351679 May This project will improve the chemistry curriculum by incorporating state of the art computer controlled analytical instruments into laboratory in struction directed to the first year chemistry student. The three instru ments chosen that meet these criteria include; a computer controlled diode array, spectrophotometer, gas chromatographs, a liquid chromatograph, and personal com puters for the laboratory use with the chromatographs. The laboratory experiments in first year chemistry will be redesigned with 30% of the present exercises elim inated as being outdated, 40% of the present experiments will be augmented with the purchased instrumentation, and the remaining experiments will be new and based on applications of the instruments that illustrate the lecture material with procedures found in modern chemistry laboratories. The students will benefit from this project in several ways including; (a) the laboratory work will gen erate more enthusiasm for and interest in chemistry; (b) they will start their training early in laboratory techniques required of a competent chemist or graduate student; (c) the laboratory work will more effectively illustrate the lecture material; and (d) they will have the opportunity to become involved in the design of their own experiments. ***
