• Research Interests

  • I am fascinated by human learning.  Today, nearly every educator inherently understands that different students seem to learn at different rates, or that different domains are better taught using differing instructional methods. But how do these profound differences come to be? How can we best leverage instructional resources to support the academic development of all students?

    In order to begin to address these questions, I apply advanced quantitative methodologies to educational data in an effort to scientifically understand the learning process: including when, how, and in whom learning occurs. Recently, I have worked to co-develop a novel methodical paradigm, called Dynamic Measurement Modeling (DMM) that may be used to quantify students’ learning capacity in a more valid way than previously used methods.

    I am also proud to be an investigator on an IES-funded grant to develop a new measure of original thinking for elementary school students based on text-mining metodology. I sincerely believe that creativity and originality are critically important mental attributes to support in students, and I am excited about advanced quantitative techniques for measuring creative attributes and modeling their development. 

    Moreover, I have closely studied two higher-order cognitive functions that allow individuals to flexibly adapt to shifting demands, and innovate around constraints and challenges: relational reasoning and creativity. In particular, I am interested in the reliable and valid measurement of these constructs, as well as the role they play in student success, especially in STEM fields. For example, I have studied how medical students and residents use relational reasoning to arrive at clinical diagnoses, as well as how engineering students creatively solve mechanical problems.
