Thorndike, Thurstone and Rasch: A Comparison of Their Approaches to Item-Invariant Measurement.
Englehard, George, Jr.
The methods used by E. L. Thorndike, L. L. Thurstone, and G. Rasch to address issues related to item-invariant measurement and the scoring of individual performance are compared. The analyses highlight the close connection among the three methods, and suggest that progress in measurement theory reflects the movement from essentially ad hoc methods to theory-based procedures for dealing with measurement problems. Data from a 1914 study by Thorndike involving 40 fifth-grade students are used to illustrate how Thorndike, Thurstone, and Rasch would approach the problem of obtaining item-invariant estimates of ability on a visual vocabulary scale. Five tables and eight figures illustrate the comparisons. A 40-item list of references is included. (Author/SLD)
