Abstract: The aim of this study was to analyze the reliability and validity of the Activities, Independent Research, Internship/Practica/Clinical, Laboratory, Online, Seminar, Standard Lecture, and Studio-Performance course forms of the Students' Assessment of Instruction (SAI) instrument. The participants were volunteers from the student population at Western Carolina University (WCU) for the spring 2007, fall 2007, and spring 2008 semesters. The reliability and validity were analyzed using confirmatory factor analysis (CFA), generalizability theory (g-theory), and hierarchical linear modeling (HLM). Findings were mixed. The Independent Research Course Form had no evidence of reliability and validity while the Online Course Form had some evidence of validity but no evidence of reliability. All other course forms had moderate to excellent validity. Suggested changes for the course forms are discussed.
