This study seeks to determine if the same five bipolar factors that appear for the ideal role concepts of public school teachers also appear for parochial school teachers. Subjects included 185 teachers from a Catholic diocese. The data were factor analyzed by means of a principal axis analysis with varimax rotation. An analysis of variance was used to compare the factor analyses. The results indicated that parochial and public school teachers have similar factor structures. When comparing factor scores of the two groups, there were significant differences on several factors, indicating that parochial school teachers adopt a more facilitating role than do public school teachers.  相似文献

A set of behavioral procedures focusing on the academic and social behavior problems of a group of adolescent students was incorporated within the context of a regular school program. The procedures, which involved manipulating type and delay of reinforcement, teaching desirable behaviors that were self-reinforcing or that others would readily reinforce, and training in several skills that are prerequisite to selfcontrol, were implemented in several classrooms through an independent grouporiented contingency system. These students performed significantly better than a matched control group with respect to grade-point average, class grades, school attendance, and length of time absent due to suspension. Changes in the contingency system throughout the year yielded differential effects on three behavioral measures: class attendance, assignments completed, and classroom behavior. The significance of these findings is discussed, and suggestions are made for future research efforts.  相似文献

This study attempts to replicate the findings of Santostefano, Rutledge, and Randell (1965), which demonstrated a relationship between the cognitive control called field articulation and reading disability in school-aged children. Two groups, reading disability and nonreading disability, were administered a series of cognitive control measures. The results confirm the findings of earlier studies that the cognitive control called field articulation is clearly implicated in the reading process. Performance on this control significantly differentiates between children who demonstrate reading disabilities and those who do not.  相似文献

In this paper, the role of extrinsic reinforcement in intrinsic motivation is discussed in terms of Deci's cognitive attribution theory. The competing response hypothesis and the frustration hypothesis are presented as alternative modes of analysis. “Undermining” is the phenomenon proposed by the cognitive attribution theorists that accounts for reported decrements in intrinsically motivated behaviors following external rewards. The literature regarding undermining in token economy research is critically evaluated. The author concludes that: (a) Cognitive attribution theory lacks parsimony, in that extant reinforcement analysis can account for undermining with equal facility. (b) Undermining is of little significance as a concept, due to its elusive and transient impact on operant behavior.  相似文献

A model of delivery of services that enables school psychologists to meet testing demands while initiating a broad range of consultative services is described. Requirements of the model include: (a) having funds available for contract testing, (b) having conferences with teachers prior to formal referral of children, and (c) having qualified contract evaluators available. Benefits, as well as obstacles to be expected in implementing the model, are discussed.  相似文献
