Modern Measurement Information Graphics for Understanding Student Performance Differences
Rittschof, Kent; Chambers, Wendy
International Journal of Teaching and Learning in Higher Education, v23 n3 p350-362 2011
We present an example analysis and corresponding information graphics of data from a cognitive ability assessment as a means to illustrate the use of a Rasch measurement approach and advantages inherent in such an approach for a wide variety of teaching and learning investigations. The importance of placing measurements of student performances and measurements of assessment item difficulties on the same scale is demonstrated through the use of the information graphics. The possibilities for teacher-scholars to begin including basic Rasch analysis and graphics within studies of students are highlighted. Improved understanding of the relationships between student performances and the validity of instruments used to assess those performances is emphasized. The importance of key measurement principles, as illustrated with an ability assessment, is discussed in relation to potential application with classroom assessment of learning and survey assessment.
