Data Acquisition Interfaces for Chemistry Labs at Seven Regional Community Colleges

该大学正在协助七个地区社区学院，艾伦县社区学院，科菲维尔社区学院，斯科特堡社区学院，独立社区学院，拉贝特社区学院，尼欧肖县社区学院和东北俄克拉荷马州A M学院，增加数据采集设备和调整相关实验，以他们的化学实验室计划。&对学生的新设备的说明包括计算机分析和显示收集的数据。四个社区学院的设备是基于游标计算器的实验室（CBL）包，在大学使用的类型。先前存在的情况导致其他三所学校选择直接连接到计算机的传感器。社区学院的化学教师也将有机化学实验室课程带到大学，以获得现有主要仪器的实践经验，包括NMR光谱仪（60和300 MHz），GC/质谱仪和FT-IR分光光度计。 在项目的第一年，各机构对现有的实验室指示进行了调整，以适应新的设备和数据分析软件。大学的一个讲习班协助社区学院的化学教师适应过程，并培训他们操作他们带学生去的主要仪器。在项目的第二年，教师增加了新的实验，增加了传感器的使用。新的实验是写在引导查询格式，适应新的化学倡议所使用的方法。 在第二年，社区学院的教师在匹兹堡州立大学操作主要仪器和教学生分析光谱方面变得自给自足。在第三年，参与者通过出版物和介绍会传播项目成果。社区学院和匹兹堡州立大学的设备能够为该地区所有化学专业的学生提供多年的服务。

The University is assisting seven regional community colleges, Allen County Community College, Coffeyville Community College, Fort Scott Community College, Independence Community College, Labette Community College, Neosho County Community College, and N.E. Oklahoma A&M College, in adding data acquisition equipment and adapting related experiments to their chemistry laboratory programs. The instructions to students for the new equipment include computer analysis and display of the data collected. The equipment for four of the community colleges is Vernier calculator based laboratory (CBL) packages, the type used at the University. Pre-existing circumstances caused the other three schools to select sensors interfaced directly to computers. The community college chemistry instructors also are bringing organic chemistry laboratory classes to the University to get hands-on experience with existing major instruments including NMR spectrometers (60 and 300 MHz), a GC/Mass spectrometer, and an FT-IR spectrophotometer. During the first year of the project, institutions adapt existing laboratory instructions to the new equipment and data analysis software. A workshop at the University assists the community college chemistry instructors in the adaptation process and trains them to operate the major instruments to which they bring students. During the second year of the project, faculty add new experiments that increase the use of the sensors. The new experiments are written in guided-inquiry format, adapting methods used by the New Traditions chemistry initiative. During the second year, the community college instructors become self-sufficient at operating the major instruments at Pittsburgh State and teaching students to analyze the spectra taken. During the third year, the participants disseminate the results of the project by publications and presentations. The equipment at the community colleges and Pittsburgh State is capable of serving all the chemistry students in the region for many years.
