This project uses resources at the University of Pittsburgh and Carnegie Mellon University to address several challenges in post-secondary science education: (i) to increase the access to high-performance instrumentation, (ii) to use cross-disciplinary knowledge, and (iii) to improve learning using interactive case studies. Our approach, for which we know of no existing model, is to develop a flexible interactive internet-based Virtual Mass Spectrometry Laboratory (VMSL) that allows for "real" problem solving while using a virtual mass spectrometer. Students using the VMSL solve known cross-disciplinary science problems by operating a virtual mass spectrometer (MS) over the Internet. The student sees "real" MS data displayed on the computer at one location while the central internet VMSL server which stores the previously collected MS data files is at another location. The data displayed are dependent on the interaction that the student-operator has with the VMSL system as she/he learns the proper experiments to conduct. This method makes scarce but important resources widely available, utilizing the Internet, and demonstrates a cost-effective and pedagogically powerful use of technology limited neither by discipline or geographic location, nor by the expense of scientific instrumentation. Our project is being developed for all undergraduate science students, including, but not limited to, those enrolled in Chemistry, Biology, Environmental Sciences, Geology, and Clinical Pharmacology courses. We hope to improve a student' s critical thinking ability and scientific problem solving skills nationwide by using a "hands-on" Virtual Mass Spectrometry Laboratory. This project is funded by the Division of Undergraduate Education in the Directorate for Education and Human Resources with co-funding from the Office of Multidisciplinary Activities in the Directorate for Mathematical and Physical Sciences.

该项目利用匹兹堡大学和卡内基·梅隆大学的资源来应对大教后科学教育方面的几个挑战：（i）增加使用跨学科知识的高性能仪器的访问权限，（ii）使用互动案例研究来改善学习。我们不知道现有模型的方法是开发灵活的基于Internet的虚拟质谱实验室（VMSL），该实验室（VMSL）在使用虚拟质谱仪时允许“真实”的问题解决。使用VMSL的学生通过通过互联网操作虚拟质谱仪（MS）来解决已知的跨学科科学问题。学生看到在一个位置上显示在计算机上的“真实” MS数据，而存储先前收集的MS数据文件的中央Internet VMSL Server位于另一个位置。显示的数据取决于学生操作员与VMSL系统的相互作用，因为她/他学习了适当的实验。这种方法使稀缺但重要的资源可广泛使用，利用互联网，并证明了对技术的成本效益和教学强大的使用既不是受纪律或地理位置的限制，也没有以科学仪器为代价。我们的项目正在为所有本科科学专业的学生开发，包括但不限于从事化学，生物学，环境科学，地质学和临床药理学课程的项目。我们希望通过使用“动手”虚拟质谱实验室来提高学生在全国范围内提高学生的批判性思维能力和科学问题解决技能。 该项目由教育和人力资源局的本科教育部门资助，并由数学和物理科学局的多学科活动办公室共同资助。
