The Role of Extended Time and Item Content on a High‐Stakes Mathematics Test

The premise of a great deal of current research guiding policy development has been that accommodations are the catalyst for student performance differences. Rather than accepting this premise, two studies were conducted to investigate the influence of extended time and content knowledge on the performance of ninth‐grade students who took a statewide mathematics test with and without accommodations. Each study involved 1,250 accommodated students (extended time only) with learning disabilities and 1,250 nonaccommodated students demonstrating no disabilities. In Study One, a standard differential item functioning (DIF) analysis illustrated that the usual approach to studying the effects of accommodations contributes little to our understanding of the reason for performance differences across students. Next, a mixture item response theory DIF model was used to explore the most likely cause(s) for performance differences across the population. The results from both studies suggest that students for whom items were functioning differently were not accurately characterized by their accommodation status but rather by their content knowledge. That is, knowing students' accommodation status (i.e., accommodated or nonaccommodated) contributed little to understanding why accommodated and nonaccommodated students differed in their test performance. Rather, the data would suggest that a more likely explanation is that mathematics competency differentiated the groups of student learners regardless of their accommodation and/or reading levels.     

Teachers' conceptualization of pupil control in elementary school physical education

Management of conduct has been considered the most important problem facing schools in America during 16 of the last 20 years (Gallup, 1988). Yet little is known about specific techniques teachers use to achieve pupil control in physical education. One purpose of this work is to describe the development of a conceptual framework for pupil control techniques. The framework was derived from 64 live observations and audiotapes of elementary school physical education lessons. A second purpose is to describe how teachers may potentially foster pupil self-control. Data were reduced through analytic induction, constant comparison, and topological analysis. The investigator placed 23 categories into three classifications as perceived by teachers: anticipatory, tutorial, and punitive. Teachers confirmed frequency of using techniques during interviews and on surveys. Intraobserver agreement tests yielded 88% for distinguishing among categories. Interobserver scores ranged from 83 to 86% agreement. Categories may serve to increase teachers' repertoire of control techniques in accordance with their ideological beliefs. For teachers in this study, facilitating self-control involves (a) selecting tutorial control techniques, (b) using indirect forms of techniques, and (c) conveying reasons for using techniques.
