Assessing complex constructs such as those discussed under the umbrella of 21st century constructs highlights the need for a principled assessment design and validation approach. In our discussion, we made a case for three considerations: (a) taking construct complexity into account across various stages of assessment development such as the…

This study explores measurement of a construct called knowledge integration in science using multiple-choice and explanation items. We use construct and instructional validity evidence to examine the role multiple-choice and explanation items plays in measuring students' knowledge integration ability. For construct validity, we analyze item…

Methodological procedures used in validating the theoretical structure of academic self-concept and validating associated measurement instruments are reviewed. Substantive findings from research related to modes of inquiry are summarized, and recommendations for future research are outlined. (TJH)

Results of an investigation of the construct validity of measurements of social and academic competencies of 175 3rd graders, 193 7th graders, and 159 11th graders made by the students themselves, teachers, parents, and peers suggest that researchers should consider making greater use of parent ratings for elementary school students.
