An at-risk profile instrument was developed for identification and service delivery for high risk students to identify students in a timely manner so that intervention could occur on a proactive, rather than reactive, basis; and to assist school district personnel to implement, monitor, and modify programmatic and staffing patterns to best meet…

The feasibility of quick norms derived by the procedure described by B. D. Wright and M. H. Stone (1979) was investigated. Norming differences between traditionally calculated means and Rasch "quick" means were examined for simulated data sets of varying sample size, test length, and type of distribution. A 5 by 5 by 2 design with a…

This paper examines the implementation of an alternate block (A/B) schedule in three high schools in Irving, Texas. The purpose is to review how time was used in 48 randomly selected high school Algebra 1, Biology 1, English 2, and U.S. History classes. Of the 48 classes, 12 observations were conducted for each course. The findings revealed a…

Using item mean squares to evaluate fit to the Rasch model was studied, also considering the transformed version of the item fit statistics. Simulations demonstrate that the critical value for the mean square used to detect misfit is affected by the type of mean square and the number of persons in the calibration. (SLD)
