The Implications of Content versus Validity on Science Tests.
Yarroch, William L.
Journal of Research in Science Teaching, v28 n7 p619-29 Sep 1991
The use of content validity as the primary assurance of the measurement accuracy for science assessment examinations is questioned. An alternative accuracy measure, item validity, is proposed. Item validity is based on research using qualitative comparisons between (1) student answers to objective items, (2) clinical interviews, and (3) student answers to essay examinations. (PR)
