Several critical concepts of applied psychometrics (e.g., measurement, reliability, validity, and factor analysis) will be explained. The important role these concepts can play in the research of engineering education will also be illustrated.
The study by Tao Hong, Dr. Purzer and Dr. Cardella: “the psychometric re-evaluation of the Design, Engineering and Technology (DET) survey” will be discussed. The purpose of this study was to re-examine the psychometric soundness of the DET survey with a new data set collected from elementary teachers representing a national population, and to present the details regarding how to appropriately conduct confirmatory (CFA) and exploratory (EFA) factor analyses and item analysis.
