My research focuses on conceptual understanding and explanation in science education. My methods combine the detailed study of situated cognitive activity, exemplified by interaction analysis, and the objective characterization of such interactions, exemplified by construct-referenced (or Rasch) measurement. My research also focuses on the application of construct-referenced measurement to embedded classroom assessment in the areas of middle and high school science and content-area literacy.
