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. *

这所历史悠久的黑人大学为理科专业开设了10年的普通化学实验课程，此次修订包括了技术的使用，旨在培养科学思维。学生们保留一个实验笔记本，设计、执行和展示一个项目。多媒体互动的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学生第一次操作程序时的焦虑，而且让学生有机会体验几个相关的实验。探讨日常经验与讲座中所学概念之间的关系。强调测量和数据分析是推导化学基本原理的最佳方法。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，在早期的实验中，仪器处理的压力更小，数据处理的压力更多。数字和图形分析的运用、技术经验以及书面和口头技能的发展，为学生进入更高级的实验室并最终进入研究生院和就业市场做好了准备。＊
