Enhancing the Undergraduate Chemistry Curriculum with Gas Chromatography - Mass Spectrometry

化学（12）本项目将气相色谱-质谱（GC-MS）纳入化学课程。《化学教育杂志》上的实验被改编成不同层次的课程。GC-MS的使用从入门课程开始，并将以越来越复杂的方式在有机、分析、仪器和高级有机课程中继续使用，最后在本科研究中使用。这样，实验将建立在学生以前的知识基础上，从引导探究开始，随着学生进入更高级的课程，逐渐在实验设计和解释方面引入更大的独立性。此外，参加调查课程的学生和参加专业发展活动的在职教师正在通过具有上下文基础的有意义的活动接触到这种技术。

Chemistry (12) This project is incorporating gas chromatography-mass spectrometry (GC-MS) into the chemistry curriculum. Experiments from the Journal of Chemical Education are being adapted for use at different levels in the curriculum. Use of GC-MS begins in introductory courses and will continue in increasingly complex ways in organic, analytical, instrumental, and advanced organic courses and finally in undergraduate research. In this way, experiments will build on students' previous knowledge, beginning with guided inquiry and gradually introducing greater independence in experimental design and interpretation as students progress to more advanced courses. Additionally, students in survey courses and in-service teachers participating in professional development activities are gaining exposure to this technique through meaningful activities which have a contextual basis.
