General Chemistry Laboratory with Computers and Calculator Based Laboratory

在这所历史悠久的黑人大学，对已有10年历史的理科专业普通化学实验室课程进行了修订，其中包括技术的使用，旨在培养科学头脑。 学生保持实验室笔记本和设计，执行，并提出一个项目。 多媒体互动实验前和实验后扩展了每个实验对学习过程的影响。 模拟实验不仅消除了第一次遵循一个程序的焦虑，而且还让学生有机会体验几个相关的实验。 日常经验和讲座中学到的概念之间的关系是追求。 测量和数据分析被强调为导出化学基本原理的最佳手段。 图形计算器和电子表格用于显示数据和搜索变量之间的关系。 基于计算器的实验室单元便于数据采集，在早期实验室会话中对仪器操作的压力较小，而对数据处理的压力较大。 使用数值和图形分析，技术经验，以及书面和口头技能的发展，更好地为学生准备更先进的实验室，并最终为研究生院和就业市场。 *

The revision of the 10-year-old general chemistry laboratories curricula for science majors at this historically black university includes the use of technology and aims at the development of the scientific mind. The students keep a laboratory notebook and design, carry out, and present a project. Multimedia interactive pre-labs and post-labs extend the impact of each experiment on the learning process. Simulated experiments not only eliminate the anxiety of following a procedure for the first time, but also give the student the opportunity to experience several related experiments. The relation between daily experiences and concepts learned in the lecture is pursued. Measurement and data analysis are emphasized as the best means of deriving the fundamental principles of chemistry. Graphing calculators and spreadsheets are used to display data and to search for relations between variables. Calculator-based laboratory units facilitate data acquisition, with less stress on instrument handling and more on data handling in the early laboratory sessions. The use of numerical and graphical analysis, the experience with technology, and the development of written and oral skills better prepare the students for the more advanced laboratories and ultimately for graduate school and the job market. *
