Self-regulating academic learning and achievement: The emergence of a social cognitive perspective 总被引:8,自引:0,他引:8
Barry J. Zimmerman 《Educational Psychology Review》1990,2(2):173-201
For three decades, social cognitive researchers have studied children's development of self-regulation as an achievement of socialization processes. I recount historically the emergence of a social cognitive perspective on self-regulation and identify its unique features. Two essential characteristics of students' self-regulated academic learning have been identified — their use of strategies and perceptions of self-efficacy. A social cognitive model of academic self-regulated learning is proposed that integrates triadic determinants of self-regulated learning (personal, behavioral, and environmental) on the basis of a strategic control loop. When students monitor their responding and attribute outcomes to their strategies, their learning becomes self-regulated, and they display increased self-efficacy, greater intrinsic motivation, and higher academic achievement. 相似文献

This study examines sources of satisfaction, indicators of stress, academic performance, and reward structure in the academic careers of male and female faculty at a major midwestern state university. Faculty pairs were selected from five academic divisions. A total of 58 matched pairs were identified. Of these, 63 faculty responded, yielding data for 23 matched pairs. Subjects were mailed the Academic Career Development Survey, consisting of 144 items. Results indicated that self-reported physical and mental health, and professional and personal life satisfaction were high for both males and females. Both males and females placed high importance on their career and on marriage/other intimate relationships; however, both reported high levels of dissatisfaction with these factors. Gender differences were found in both satisfaction and type of stress reported; no gender differences were found in composite teaching and research performance indices. Salary data, obtained for 42 matched pairs, indicated similar salary levels for men and women. Results were discussed with respect to prior research on gender differences and the academic career. 相似文献

This article reports the results of research to determine if a significant interactive effect exists between students' lingual background (English as a primary language [EPL] versus English as a secondary language [ESL]) and question format on students' examination scores. Students were administered examinations made up of four subtests covering the same subject matter. The subtests were composed of four question formats: multiple choice quantitative, multiple choice theoretical, open-ended quantitative, and open-ended essay questions. Based on analysis of variance and analysis of covariance, significant differences were observed between EPL and ESL students depending on the type of question on the examination. 相似文献

Markets,inequality, and urban schooling 总被引:1,自引:0,他引:1
Stephen J. Ball 《The Urban Review》1990,22(2):85-99
This paper considers the intellectual and political antecedents of current attempts by the British government to create a market in state education. The implications of market forces for school organization, educational values, teachers' careers and conditions of work, and equality and social justice in the inner city are also explored. It is argued that policies of competition between per capita funded schools are likely to increase the existing inequalities in school provision in England to the disadvantage of children in urban areas. 相似文献

Mother-Toddler Problem Solving: Antecedents in Attachment, Home Behavior, and Temperament 总被引:2,自引:0,他引:2
In a widely cited study, Matas, Arend, and Sroufe showed that mother-toddler interaction during problem solving at age 2 years was related to the child's prior attachment security. The current study asked (1) whether an independent laboratory could replicate this attachment finding, and (2) whether problem-solving interactions relate to mother-child interactions observed at home and to child temperament measured at 6, 13, and 24 months. Replicating Matas et al., secure dyads worked more competently, and mothers showed better quality of assistance and supportive presence. Mother-child home interaction also predicted problem solving: positive involvement at home predicted effective, unconflicted problem solving. Negative control at home did not predict problem-solving interaction. Unadaptable temperament was generally related to dependency in problem solving. Several patterns of correlations appeared to be mediated by sex of child, e.g., difficult temperament in boys predicted more effective, unconflicted problem solving, while for girls it predicted more conflict. 相似文献

A conceptual overview of the regression discrepancy model for evaluating severe discrepancy between IQ and achievement scores 总被引:1,自引:0,他引:1
L D Evans 《Journal of learning disabilities》1990,23(7):406-412
A conceptual overview of the Regression Discrepancy Model (RDM) for determining severe discrepancy between IQ and achievement scores is presented in order to enhance understanding of the model without the use of the complex mathematical equations that constitute the model. The six specific goals of the RDM are identified, and figures illustrate the manner in which the model accomplishes each goal. Figures are also provided from a RDM computer output showing the basic outcomes of the model. Advantages and disadvantages of the RDM are discussed to further promote understanding of the model. 相似文献

THE NEW EDUCATION SYSTEM was implemented in 1980 with the objective of arresting the high attrition rates of premature school leavers by providing a differentiated curriculum to suit the needs and abilities of different learners in Singapore. As a result, streaming was introduced into schools to bring out the best in every child regardless of ability. Against such a background, health, welfare and special educational services and programs for disabled people are discussed. To support the changes and improvements recommended for disabled people as contained in the Report of the Advisory Council on the Disabled(1988), the training of teachers and other rehabilitative staff are highlighted. From 1988, opportunities for the disabled have increased tremendously and the enthusiasm and efforts put in by all parties concerned with the welfare of the disabled which have greeted these recommendations thus far, augurs well for special educational development in Singapore. 相似文献

In 1974–75 at the K.U.Leuven Project Work as Practicals was started in the first-cycle engineering curriculum aiming at (1) the integration of separate teaching items and 7lpar;2) the integration of theoretical and practical or numerical aspects of those items. After 4 years the evaluation of it was more than satisfactory. The teaching team of the Chemistry course has integrated this system of practicals into their normal chemistry practicals. In this way more students 7lpar;currently only 20%) would be able to profit from the new education curriculum, now called ‘Long-term Practicals’. About 20%of the sophomore student volunteers are working for about 15 hours spread over 5 weeks at a mini-research subject in close contact with the members of the teaching team, using the instruments of the Chemistry Division, reading the literature, writing a report after the practical work, with discussion and evaluation of the work with their team-leader. To make it possible that all the sophomore students (400 students in 1987)could profit from this new education system, the physics, mechanics, mathematics, etc. practicals have to adapt to the same integrated practical system. 相似文献
