In this comment we explain why we believe the analysis that is used is inappropriate, and the proposed modified CLASS will be measuring something quite different, and less useful, than the original. The CLASS was based on extensive interviews with students and is intended to be a formative measurement of instruction that is probing a much more complex construct and with different goals than what is handled with classic psychometrics. We are writing this comment to reiterate the value of combining techniques of cognitive science with statistical analyses as described in detail in Adams & Wieman, 2011 2 when developing a test of expert-like thinking for use in formative assessment. This type of approach is also called for by the National Research Council in a recent report 3.
