Integrating Group Laboratory Activities Across the Chemistry Curriculum

一项名为“在化学课程中整合小组实验室活动”的倡议正在努力解决化学教育中的一个严重问题。非科学和科学专业的入门课程不参与合作小组实验室练习有关的环境，先进的材料，和生物技术，因为缺乏通用的，国家的最先进的仪器。 作为仪器分析的一个小组项目，化学专业的学生正在开发和测试涉及CE，IC，红外和维斯光谱的协议。这些实验被导出到介绍化学实验室课程，并由科学和非科学专业的组合组执行。化学专业的学生，作为同行指导员，指导学生执行实验，加强化学概念。该项目支持三个主要目标，在修订后的介绍化学课程：学生在普通化学，我们周围的化学世界和仪器分析之间的合作实验室互动;在相关背景下，以现代化学观点的定量化学原理的严格演示;和一个具有挑战性的项目为导向的实验室经验，促进同行导向的小组学习。该项目的受众包括传统的大学年龄的妇女谁是在介绍化学课程注册，以及初级和高级化学专业。 大约45%的化学世界课程的学生是兼职教师。 该项目影响了300多名学生。该项目的影响是，它增加了学生在高年级和低年级课程之间的互动;向妇女介绍了以技术为中心的实验;向副教授介绍了在未来课堂上对他们很重要的教学法;在现代化学实验的背景下介绍了使用仪器的复杂概念;并为科学和非科学专业创造了同行指导的学习机会。

An initiative entitled Integrating Group Laboratory Activities Across the Chemistry Curriculum is working to solve a serious problem in chemistry education. Nonscience and science majors enrolled in introductory courses are not involved in cooperative group laboratory exercises relevant to the environment, advanced materials, and biotechnology because of the lack of versatile, state-of-the-art instrumentation. As a group project in Instrumental Analysis, chemistry majors are developing and testing protocols involving CE, IC, infrared, and VIS spectroscopies. These experiments are being exported to introductory chemistry lab courses and executed by combined groups of science and nonscience majors. Chemistry majors, acting as peer-instructors, guide students in executing experiments that reinforce chemical concepts. The project supports three major objectives in a revised introductory chemistry curriculum: cooperative laboratory interaction between students in General Chemistry, The Chemical World Around Us, and Instrumental Analysis; rigorous demonstration of quantitative chemical principles in relevant contexts to modern chemical perspectives; and a challenging project-oriented laboratory experience that facilitates peer-directed group learning. The audience for this project includes women of traditional college age who are enrolled in introductory chemistry courses, as well as junior and senior chemistry majors. About 45% of the students in the Chemical World course are preservice teachers. The project affects more than 300 students. The impact of this project is that it increases interaction between students in the upper- and lower-division courses; introduces women to technology-centered experiments; introduces preservice teachers to pedagogy that will be important to them in their future classrooms; introduces sophisticated concepts in the context of modern chemical experiments using instrumentation; and creates peer-directed learning opportunities for science and nonscience majors.
