We examined university students' academic help-seeking under task-involved and ego-involved classroom conditions. The effects of these motivational sets on frequency of help-seeking were expected to depend on students' attributions for failure. Use of two types of help sources was investigated: (1) an instrumental help source that imparted useful strategies to the help-seeker, thereby allowing him or her to retain responsibility for solving the problem; (2) an executive help source that disclosed the solutions, thus relinquishing the help-seeker of the responsibility for independent problem-solving. We found that ego involvement increased executive help-seeking in students who attributed failure to low ability, but not in students who made effort attributions. Moreover, task involvement produced more instrumental help-seeking than ego involvement in all students regardless of their attribution style. Since executive help-seeking can impede academic development by inhibiting skill acquisition and by fostering dependence on a help source, university teachers should consider classroom strategies that promote task involvement.Support for this research was provided to Jamie-Lynn Magnusson by The University of Manitoba Research Funds Committee and the Social Sciences and Humanities Research Council of Canada. Support was provided to Raymond P. Perry by Franz E. Weinert, the Max Planck Institute, Munich. Portions of this paper were presented at the meetings of the American Educational Research Association. This paper is based on research conducted for a doctoral thesis submitted by Jamie-Lynn Magnusson, under the supervision of Raymond P. Perry, to the Department of Psychology at The University of Manitoba.  相似文献

This paper reports research that focuses on student teachers' reflections on their learning process in a collaborative problem-solving context. One group of students with limited mathematical backgrounds worked on two problems in geometry without teacher intervention. We focus on two episodes from the group dialogues. In the first episode (section 5) the students basically reflect on two key issues. The first reflection is related to the concern of making problem-solving tasks too difficult in general while the second reflection has to do with the concern of participation in the solution process. The students discuss how they can give hints or introduce particular ideas before presenting a solution in order to stimulate colleague participation, thus promoting the understanding of the solution process. The second episode (section 6) illustrates the reflection of students on their preparation as future teachers of mathematics. They emphasise that the experience of getting stuck with a problem may help them to better understand the frustration pupils experience while working on unfamiliar problems in classroom. Based on the experience of getting stuck, the students reflect on how they could motivate themselves as well as pupils to work on mathematical problems. They suggest that a good strategy is to start working on an easier problem. If they succeed in coming up with a solution to that problem, they think that it is then more stimulating to proceed to a difficult one.  相似文献

For an introductory undergraduate biochemistry class, we developed an interactive, out of classroom, team project that would allow students to gain a better understanding of protein structure and function. This project involved the use of the molecular visualization program RasMol and computer simulated site-directed mutagenesis of selected amino acids of the enzyme, Uroporphyrinogen decarboxylase. Survey data from students after completion of the project indicated that they had developed a more complete understanding of protein three-dimensional structure leading to functionality.  相似文献

This article considers the relationship between differential homework task difficulty, student engagement and performance across four Irish post-primary school sites. A total of 236 participants completed all elements of this study. All participants were junior cycle students, aged between 12 and 16 years. The study employed a standardised test–retest approach, with a one week interval between tests. Between testing, participants were randomly subdivided into three cohorts. Each cohort received homework questions of different difficulty levels to complete for one week. The results of this study found that Cohort A, who received the least difficult homework tasks, completed the most non-compulsory questions. Although Cohort A demonstrated higher levels of engagement, no statistically significant difference was found in the change in performance scores of the three cohorts. The results highlight the negative impact of increased task difficulty on student engagement with independent homework tasks. The findings suggest that in order to support student engagement it is important that teachers afford ample opportunity for student success when designing self-directed tasks such as homework.  相似文献

Two quasi-experimental methods – fixed effects (FE) and virtual control records (VCR) – were used to measure charter schooling in 14 states and two districts. The new VCR method uses all available observable charter student characteristics and prior performance to create a composite comparison record. A head-to-head comparison of the FE and VCR methods used the same charter students to test the FE control (e.g., the charter student's own traditional public school experience) and the VCR for equivalence. The comparison produced highly similar estimates; charter coefficients were identical in sign and significance and of the same general magnitudes. In an analysis of the sampling fractions included in each method using all available tested charter students, the VCR method was found to produce more generalizable results. In the policy analysis, charter school quality was found to be demographically and geographically uneven with only 19 percent of charter schools outperforming their local markets.  相似文献

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test.  相似文献

A study of the initial phase of intensive work with families indicated that whilst outreach techniques had dramatically reduced physical injury there was long-term distortion in the child's relationship with mother (parent) less amenable to change. The most recent phase of work has concentrated on direct treatment for the abused child, using a multidisciplinary team that includes a play specialist and child psychotherapist in addition to the social workers involved. Out of a total number of 66 children seen between April 1977 and December 1979 it was alarming to find that almost all were emotionally disturbed; even if the abuse did not reoccur they remained with considerable problems. The study highlights the degree of emotional disturbance suffered by these abused children and how they can be helped by focusing on their particular treatment needs. It is important to assess all children in the family situation and not to miss the quiet, depressed, withdrawn child who might not have been the subject of the initial referral. In some instances the needs of the child may outweigh those of the family and the focus of treatment must be on the child.  相似文献
