RESEARCH INTERESTS

The field of psychometrics dates back more than a century and is concerned with the theory and practice of psychological and educational measurement. Researchers in this field have established protocols to develop and evaluate a wide variety of assessment instruments, including multiple-choice concept inventories. With these protocols, chemists can make measurements of student knowledge and understanding with the same care and precision they use in the laboratory. Our projects make use of the Rasch and Item Response Theory models, as well as Structural Equation Modeling, during the development of assessment instruments. Using these models during the development phase of an instrument will lead to more reliable and valid data once the instrument is completed.
