Probability in the Measure of Achievement by George S. Ingebo, 1997
Shows the advantages of Rasch measurement for school district testing programs. Dr. George Ingebo contrasts the results of Rasch methods with conventional statistics for assessing student responses to basic skills testing. He presents testing issues in an accessible, down-to- earth manner.
Chapter I shows how the Rasch probability-based method produces measures that are more useful for students, parents, teachers, administrators and researchers than information provided by conventional population-based statistics.
Chapter 2 discusses the technology for designing and maintaining a large bank of curriculum test items that facilitate a reliable and precise measure of a student's ability growth between fall and spring and from year to year.
Chapter 3 presents a dozen research projects comparing conventional grade-level tests with Rasch calibrated levels-tests. Their findings support the use of the Rasch testing model. Chapter 4 offers a set of statistical comparisons of groups that can be useful to school district Administrators.
This book takes the uncertainty of student achievement testing out of the closet and looks it over on purpose - not with some comforting fiduciary limit, but with professional opinion backed up by wisdom and by a feeling of responsibility. 148 pp. Figs. ISBN 0-941938-09-3. LC# 97-076496.
