Until recently, general assumptions were made about the importance of the self-system in self-regulation (e.g., importance of self-concept, self-efficacy, self-esteem), but the more specific underlying structures and processes of the self-system that are involved in this self-management process were rarely addressed. This article presents theoretical and empirical support for a preliminary causal model of the role of the self-system in self-regulated learning. The model postulates that for self-regulated learning processes to be engaged, students must view themselves as activators of these processes (i.e., they must possess positive self-views in general as well as have specific perceptions of competency and control in particular learning situations). The model also postulates a recursive and reciprocal relationship between the processes involved, such that continual self-evaluations of competency and control can force changes in perceptions of self, the learning task, goal importance, etc., that, in turn, exert continuing influences on motivation, use of self-regulatory processes, and actual task performance. Educational implications of the model are discussed along with future research directions. 相似文献

In an exploratory study, peer tutoring in higher education is examined for students with visual impairment and students with learning disability (LD). Data were collected by means of interviews and focus groups. Findings indicate both academic and social benefits for tutees and tutors. Difficulties encountered are discussed, and differences between the two populations are raised. It is suggested that the visibility and complexity of the student's disability affected the tutoring encounter. Professional guidance is suggested as a means of reducing tutoring problems and increasing benefits. 相似文献

This study investigated the effects of Guided Discovery vs. Didactic methods of instruction upon the acquisition of certain inquiry skills. At the same time, the effects of method on the attainment of factual-conceptual achievement was assessed. Hypotheses of no interaction of the methods variable with the learner variables—sex, measured intelligence, creativity, interest in science, general scholastic achievement, and science achievement—were also tested. The sample consisted of 140 8th-grade students. The duration of the experimental unit was six weeks. The subject matter was the same for each, “Early Man in America.” The results favored the Didactic group for the factual-conceptual achievement and the Guided Discovery for the acquisition of inquiry skills. However, in the latter there was an interaction of method with levels of measured intelligence and achievement. 相似文献

Pigeons were trained on a variant of the autoshaping procedure in which a keylight stimulus of increasing brightness was used to signal the passing of a 30-sec interfood interval (IFI). Key-pecking developed in all subjects within the first session (65 trials). Within trials, pecking began midway through the IFI, increased throughout the remainder, and decreased just before food delivery. Other behavioral stereotypies were also recorded: Low light levels were associated with a retreat to the rear of the test chamber, and medium light levels (during the midportion of the IFI) were associated with high rates of pacing toward and away from the food source. Probe trials revealed that pecking, pacing, and retreat were all under strong stimulus control; that is, when the light was held constant at its lowest or highest brightness, or when the brightness ramp was presented in reverse order, the behavior pattern almost invariably remained tied to stimulus brightness. Results are discussed in terms of associative and nonassociative sources of the form and sequential characteristics of the behavior. 相似文献

The purpose of this research effort was to examine Black male students' self‐perceptions of academic ability and gifted potential in science. The purposeful sample consisted of nine Black males between the ages of 14 and 18 years. Four categories of self‐perceptions of academic ability and gifted potential emerged from the data. These included: (a) gifted high achievers; (b) gifted “could do better” high achievers; (c) gifted “could do better” situational nonachievers; and (d) gifted “could do better” underachievers. Science teachers' influences that referenced participants' academic achievement pointed to validation. Participants' perceptions regarding how science teachers' influenced their academic performance focused on science teachers' content knowledge. Power dynamics germane to Black male participants' value or worth that directed their efforts in science learning environments are discussed. Implications are posited for science teaching, science education programs, and future research. This research endeavor was based on two premises. The first premise is that Black males' self‐perceptions of academic ability affect their science academic achievement. The second premise is that, given parental, peer, and community influences, science teachers have considerable influence on students' self‐perceptions of academic ability. However, the focus of this research was not on parental influences, peer influences, or any potential influences that participants' communities may have on their academic achievement. © 2005 Wiley Periodicals, Inc.
