A Valid and Reliable Instrument for Cognitive Complexity Rating Assignment of Chemistry Exam Items
Knaus, Karen; Murphy, Kristen; Blecking, Anja; Holme, Thomas
Journal of Chemical Education, v88 n5 p554-560 May 2011
The design and use of a valid and reliable instrument for the assignment of cognitive complexity ratings to chemistry exam items is described in this paper. Use of such an instrument provides a simple method to quantify the cognitive demands of chemistry exam items. Instrument validity was established in two different ways: statistically significant correlations between expert-based cognitive complexity ratings and student performance (as measured through statistical difficulty of items), and statistically significant correlations between expert-based cognitive complexity ratings and student mental effort ratings. Key benefits associated with instrument use include an enhanced understanding of the cognitive complexity of chemistry assessment tasks and as a means for characterizing exam content for the measurement of cognitive development. (Contains 1 table and 8 figures.)
