Using Expert Witness Testimony with an Illicit Substance Analysis to Increase Student Engagement in Learning the GC/MS Technique

Abstract

Authenticity in a forensics lab activity is an important tool in combating the CSI effect that has created unrealistic expectations for forensic science. In this chapter, we provide a description of a forensics lab activity that analyzes a simulated illicit compound using gas chromatography-mass spectrometry (GC/MS). In addition to teaching students how to perform GC/MS analysis, we expand this activity by having students testify about the results of their analysis in a simulated courtroom environment. By combining the teaching of standard analytical technique with the experience of testifying about the results, students are able to have a more authentic experience of being a forensic analyst, both inside and outside the laboratory setting.
