Achievement goal theory is an important theoretical framework for understanding achievement motivation. In previous studies, a mastery orientation has been shown to be related to students’ interest, while a performance orientation has been found to be predictive of academic performance outcomes such as course grades. In this study, the two mastery sub‐scores from the Multiple Goals Theory Measure (MGTM) of academic motivation, which was developed specifically from achievement goal theory, was found to be predictive of college grades for a sample of 257 undergraduates at a public university in the north‐eastern United States. Additionally, the results support a trichotomous model of achievement orientations comprising mastery approach, performance approach, and avoidance. The MGTM appears to hold promise as a diagnostic tool, but additional research is required on its resistance to faking and other threats to validity. 相似文献

If it is assumed that student failure in the classroom situation is the result of inadequate performance skills rather than a lack of ability, then the attention of the educator should more properly be directed at teaching the student to develop effective methods of studying. The present experiment employed a Programmed Student Achievement (PA) procedure which required that the student evidence 100% mastery of discrete units of material. Two PA contingencies which differed in the intensity of the consequence of failing to evidence mastery were used, testing the hypothesis that the PA effect is analogous to avoidance conditioning. In addition, generalization of the effect of PA on performance in courses taken concurrently was evaluated. The performance of PA students was found to be significantly superior to that of control students on both weekly quizzes and major exams; however, performance under the two experimental contingencies did not differ. Additionally, the PA effect did not generalize to performance in other courses. The implication of these data for an avoidance hypothesis account of the PA effect is discussed. 相似文献

This study investigated what kind of supportive information can be effective in improving the situation where there were severe motivational challenges. Motivational and volitional email messages (MVEM) were constructed based on an integrated model of four theories and methods, which are Keller's ARCS model, Kuhl's action control theory, Gollwitzer's Rubicon model of motivation and volition, and Visser & Keller's strategy of motivational messages, and distributed with personal messages created based on audience analysis to a large undergraduate class. In order to examine the effects of the messages on motivation for the course, study habits (study time), and achievement (test grade), MVEM were sent to 30 students (Personal Message Group: PMG) with personal messages and to 71 students (Non‐Personal Message Group: NonPMG) without personal messages. Results indicated that PMG showed a higher level of motivation, especially in regard to confidence, than NonPMG. Also, the mean test grade of PMG increased so that the initial difference of the test grade between the two groups significantly decreased. Although there was no difference between the two groups in study habits, the findings suggest that personal messages addressing specific individual problems raise the positive effects of MVEM constructed based on the integrated model. Future research directions are discussed. 相似文献

Distance‐learning courses were classified with regard to their use of computer‐mediated interaction and the degree to which such interaction was integrated into the curriculum and the assessment regime. This produced four groups of courses varying according to their use of interaction and integration. The impact of interaction and integration was investigated in terms of their effects on students' performance, their perceptions of academic quality and their approaches to studying. In all three respects, variations within the groups of courses proved to be more important than variations between the groups. Interpretation of these results suggests that the adoption of interactive environments within computer‐mediated learning may not be enough in itself to lead to positive learning outcomes. We found no evidence for this assumption in terms of students' completion rates, pass rates, grades, perceptions of the quality of their courses or approaches to studying. Large variations in the measured indicators were found between courses, and these appeared to be largely independent of the effects of interaction and integration. Courses may differ markedly with regard to how they make use of computer‐mediated interaction and how this is integrated into the curriculum and the assessment regime. A case study approach is suggested as being more likely to identify the impact of specific designs based on computer‐mediated interaction and to bring together the diverse student responses arising from the use of such interaction in their studies. 相似文献

This is the report of a five month study, undertaken by Sundridge Park Training Technologies in association with Guildford Educational Services to assess the potential of smart card technology to support learning and the management of learning. The study had two strands—the state of the art of the technology and its potential for supporting, delivering and managing learning. In addition to a study of the literature and extensive discussions with people using smart cards, potential users of smart card and visionaries, the project team developed two illustrative systems using cards to store personal data relating to education and training. The term ‘smart card’ is often used loosely to describe three different types of card, each of which is similar in general shape and size to a traditional credit card. These are: memory cards, laser cards—and true smart cards incorporating a processor and memory. This study has been concerned with memory cards and smart cards. The focus for smart card applications has been predominantly financial: there are relatively few applications in education or training. A notable exception is the large scale project at the University of Bologna which uses smart cards to manage the progress and achievements of a large number of students in the Department of Electronics. The two illustrative systems provided valuable experience of using memory cards and smart cards in quasi‐real education and training applications. They highlighted the problems of limited memory capacities and confirmed the high level of user acceptance reported by other trials. We can expect considerable advances in the technology of both memory cards and smart cards over the next months and years. The memory capacities of both types of cards will increase many‐fold and the unit costs will fall as large quantities of cards are produced for financial applications. Education and training applications will benefit from this expanding market. The major surprise from the study was the level of interest in the work and the enthusiasm expressed by almost all of those who came to hear of it. The general level of awareness of smart card technology was found to be low. However, the requirement for a system which will enable individuals to manage and own their learning on an extended timescale was generally recognised. Some of the possible applications for smart cards and memory cards in education and training had emerged before the official start of the study and it is clear that the technology is potentially pervasive. The project team and those consulted identified a wide range of possible applications both in education and in training. These focussed on assessment, personal course planning and management, identification of relevant learning opportunities, and the ownership of learning. It was felt that, over the next few years, smart cards are very likely to be in common use as credit cards for financial applications. Therefore, their use for education and training should be planned now. The recommendations from the study are that: More detailed studies are needed to find out how smart cards and memory cards could be used by different organisations in a fully operational system; Standards should be established for smart card applications in education and training, similar to those governing financial applications; Applications should be developed after the standards have been established. To be convincing, these should take a case study approach with small pilot studies in a variety of contexts and must follow real needs rather than attempt to drive them; The case studies would then form the basis for a campaign to increase awareness of smart cards and their potential for education and training, together with a programme for building an infrastructure to support the proposed systems. The public sector should fund the task of developing standards and providing interfaces with existing educational systems and projects to demonstrate the feasibility of various applications. Since educational standards have a European dimension, the European Community may be a source of support for work in the area of standards. At the same time, private sector funding should be sought for skill development and career development systems in industry and in education. The Training Agency itself should consider the application of smart card technology to the control and management of the Youth Training Scheme (YTS). 相似文献

The article examines the theoretical and empirical literature on higher education’s role in relation to social equity and
related notions of citizenship, social justice, social cohesion and meritocracy. It considers both the education and the research
functions of higher education and how these impact upon different sections of society, on who benefits and who loses from
them. Questions for future research on the wider impact of higher education are posed as well as some research questions on
the narrower issue of widening participation. 相似文献

This study evaluated the Gentle Warrior Program, a traditional martial arts–based intervention to reduce aggression in children, as it was implemented in three elementary schools. The sample consisted of 254 children in grades 3, 4, and 5 who participated in the Gentle Warrior Program as part of a larger school violence intervention. Results indicated that boys who participated in more Gentle Warrior sessions reported a lower frequency of aggression and greater frequency of helpful bystanding (i.e., helpful behavior toward victims of bullying) over time, relative to boys with less frequent participation. The effect of participation on aggression was partially mediated by empathy. The effect of participation on helpful bystanding was fully mediated by changes in student empathy. No significant results were found for girls. Results of the study provide preliminary support for the use of martial arts–based interventions to address bullying in schools for boys, by teaching empathy, self‐control, and peaceful strategies to resolve conflicts. © 2008 Wiley Periodicals, Inc. 相似文献

As part of a longitudinal twin study of literacy and language, we conducted a behaviour‐genetic analysis of orthographic learning, spelling and decoding in Grade 2 children (225 identical and 214 fraternal twin pairs) in the United States and Australia. Each variable showed significant genetic and unique environment influences. Multivariate analyses revealed very high genetic correlations among the variables, indicating that the same genes are involved in their aetiology. These genes are partly independent of those contributing to intelligence. A further analysis indicated that the covariation between decoding and orthographic learning is mediated by shared genes rather than by a direct causal path. The authors argue that a learning parameter, most directly assessed by orthographic learning in this study, underlies all three literacy variables. The results are also discussed in relation to Share's self‐teaching hypothesis, which may require modification. 相似文献
