Improving Student Instrumentation Skills with Pre- and Post-lab Computer Simulations

玛拉娜·布莱克本，圣凯瑟琳学院9455394财年$60,012圣保罗，明尼苏达州551051750课程和课程化学标题：通过实验室前和实验室后的计算机模拟提高学生的仪器技能正确使用仪器是物理和生命科学不可或缺的一部分，然而，由于实验室时间和仪器供应的限制，许多学生从未成为自信的操作员，甚至是熟练的操作员。为了在实验室练习前介绍原则和程序，并在实验室后加强关键的实验想法，将开发一系列对实验室设备和附带文本材料的交互式计算机模拟。这些模拟允许学生按照自己的节奏单独或分组探索乐器的概念。使用包含框图方法的基于图标的模拟引擎/环境，可以更快地创建逼真和复杂的模拟(通过在线帮助、文本和图形输出以及动画)，并且可以很容易地为特定课程和观众量身定制。这些练习促进了逻辑思维、主动学习以及对假设的表述和检验。

Marlana Blackburn DUE 9455394 College of St Catherine FY1995 $ 60,012 Saint Paul, MN 551051750 Course and Curriculum Chemistry Title: Improving Student Instrumentation Skills With Pre- and Post- lab Computer Simulations Proper use of instruments is integral to the physical and life sciences, yet many students never become confident or even comfortable operators because of limits on laboratory time and instrument availability. To introduce principles and procedures before laboratory exercises and to reinforce key experimental ideas after laboratories, a series of interactive computer simulations of laboratory devices and accompanying text materials will be developed. These simulations allow students to explore instrument concepts at their own pace, alone or in groups. Using an icon-based simulation engine/environment which embodies a block diagram approach, realistic and sophisticated simulations (with on-line help, text and graphical output, and animation) can be created much more rapidly than those written in higher-level languages and can be easily tailored to specific courses and audiences. The exercises promote logical thinking, active learning, and the formulation and testing of hypotheses.
