The study examined regular-classroom teachers' attributions and instructional prescriptions for normal achieving (NA), educationally handicapped (EH), and educable mentally retarded (EMR) pupils. Teachers were provided an experimental packet containing simulated background and current achievement information on an NA, EH, or EMR pupil. Background descriptive information reflecting an NA, EH, or EMR pupil affected teachers' failure but not success attributions as well as the manner in which they revised their failureattribution ratings. In addition, it was found that teachers' initial instructional prescriptions were anchored by descriptive information reflecting characteristics of NA, EH, and EMR pupils. However, as teachers continued to receive current achievement information their instructional decisions appeared to be more weighted on pupils' current performance and less on achievement history. Findings are discussed in light of attributional research and current federal legislation mandating education of handicapped pupils in regular-education settings to the maximum extent possible.Attribution theorists are concerned with individuals' perceptions of causes of events in their environments (Kelley, 1967;Weiner, 1972). Of particular interest to educators are the attributional investigations of Weiner and his colleagues (see Weiner, 1972Weiner, , 1974, who examined the antecedents and behavioral consequences of individuals' perceptions of the causes of their own and others' successes and failures on tasks. Moreover, there is evidence to suggest that teachers' educational prescriptions are, in part, a function of their attributions for student success and failure on achievement tasks. Research in attribution theory may be interpreted to suggest that a teacher may ascribe the following attributions for pupil performance: pupil ability, effort, mood, or luck; task difficulty; or teacher ability and effort (Rosenbaum, Note 1; Weiner, 1972). Weiner and Kukla (1970) reported that manipulation of information regarding pupil ability, effort, and performance on a task affected teachers' rewardpunishment feedback to the pupils. In addition, findings from research on teacher expectations may be interpreted to suggest that information on students' ability, for instance, IQ scores and labels such as &dquo;gifted,&dquo; may affect teacher interactions with students (Rubovits & Maehr, 1971).'This paper is based on a dissertation submitted to the University of California, Los Angeles, in partial fulfillment of the requirements for the doctoral degree. at MCMASTER UNIV LIBRARY on March 31, 2015 sed.sagepub.com Downloaded from 326With the passage of P.L. 94-142, it is required that exceptional pupils be placed in the least restrictive educational alternative. That is, to the maximum extent possible, handicapped pupils are to be educated with children that are not handicapped. Therefore, many exceptional pupils classified as educationally handicapped (EH) -i.e., pupils of normal intelligence exhibiting behavioral and/or learning p...
