Mental toughness can be conceptualised as a set of attributes that allow people to deal effectively with challenges, stressors and pressure. Recent work has suggested that it may be a valuable construct to consider within educational settings. The current studies explored the associations between mental toughness and educational transitions. Study 1 examined the relationships between mental toughness and concerns about moving to a new school in 105 children aged 12–13 years of age. The results revealed significant relationships between several aspects of mental toughness, but particularly confidence in abilities, and children’s concerns. Study 2 examined the relationships between mental toughness and adjustment to university in 200 undergraduate students at various stages of their course. The results revealed a role for several aspects of mental toughness; commitment, control of life, control of emotion, confidence in abilities and interpersonal confidence. The results are discussed in terms of implications for educational practice. It is suggested that measures of mental toughness could be used to identify individuals who may benefit from additional support during transition to a new school or to university, and that future research should explore the potential benefits of mental toughness training.  相似文献

Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.  相似文献

Pigeons categorized binomial samples produced by two complementary random processes. Samples were 1, 2, 4, or 8 successively presented outcomes (vertical or horizontal lines) of, in effect, tossing one of two equally likely coins. One coin (A) was biased in favor of vertical, and the other coin (B) was similarly biased in favor of horizontal. Choosing red or green stimuli presented after each sample was reinforced with food if coin A or coin B had been tossed, respectively. In that sense, choosing red or green was logically analogous to inferring that the statistical evidence reflected tossing of coin A or coin B, respectively. The statistical diagnosticity of a sample, the relative likelihood of its having been produced by a particular coin, equaled, except for sampling fluctuation, the relative frequency of reinforcement of a particular color given that sample, and was experimentally varied by the bias on the coins and by sample size. All the variables that affect optimal, formal inference about binomial samples also affected intuitive inference. But inferences were very suboptimal: “undermatching” was obtained in part due to control of categorization by the sequential structure of binomial samples. These results reveal limitations of optimality theories for animal decision making in the face of uncertainty when observations in samples are presented successively. On the other hand, they are generally compatible with molecular analyses of instrumental learning which assign an important role to the local temporal organization of events preceding reinforcement. Most generally, they show that maladaptive control over intuitive statistical inference by a variable upon which optimal performance does not depend is neither a uniquely human phenomenon nor dependent upon linguistic strategies.  相似文献

The results of recent studies into the use of the concept mapping heuristic seem to demonstrate that meaningful learning results through its use in science classrooms. While this underscores the need to use more effective instructional strategies in science teaching, the issue of the intervening variable of anxiety in learning and science achievement, and the possible use of a metacognitive strategy in anxiety reduction have not been addressed. This study, therefore, sought to find out if the metacognitive strategy of concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 (30 boys, 21 girls) senior secondary one (grade 10) students participated in this experiment. Two instruments—the Zuckerman Affect Adjective Checklist and the Biology Achievement Test—were used in pre- and posttest administrations to measure the treatment effect on anxiety and achievement, respectively. Findings support the stand that concept mapping is significantly more effective than the traditional/expository teaching strategy in enhancing learning in biology. In addition, it apparently reduces students' anxiety towards the learning of biology. A significant reduction of anxiety was noticed for male subjects.  相似文献

Mini-languages are a visually intuitive, simple and powerful way to introduce students to programming. They are a good foundation for general computer science instruction, provide insight into programming for the general population, and teach algorithmic thinking. The goal of the paper is to provide an extensive review of the mini-language approach to teaching programming. For different audiences and in different countries, the authors have extensive experience in design and application of mini-languages. We outline the problems that motivate the application of this approach, present a brief history, review several existing mini-languages, and provide discussion of lessons learned. In particular, we discuss how to choose a mini-language for a particular group of students and list some requirements for a successful application of a mini- language. We conclude with a discussion of possible future directions of the mini-language approach development  相似文献

知识管理在中美教育机构中的应用研究   总被引:9,自引:0,他引:9  
目前知识管理在教育机构中的应用较为滞后 ,但其思想和方法同样适用于像大学、教育管理部门这样的组织机构。教育机构也可以通过实施知识管理达到提高响应能力和工作效率的目的。在高等教育中 ,知识管理工作体现在面向学生的教学和管理活动中。通过对中美两国教育机构调研的数据分析可以看出 ,在与知识管理相关的因素分析上 ,如知识管理的实施与激励形式、作用力和学校规模等方面 ,中国学校与美国学校在认识上具有不同的相关程度。这些差异反映了两国知识管理发展水平的不同 ,同时 ,对中国的高校实施知识管理具有启发意义 ,即知识管理本身本非目的 ,而是一种手段 ,应将它同具体的工作有机结合 ,才能取得更好的效果。  相似文献

Correlation is introduced intuitively early in the school curriculum by considering patterns in scatter diagrams. Later on, various formulae are used for calculating correlation coefficients. This article suggests ways in which the formulae can be related to the scatter diagrams.  相似文献

This paper deals with the broad concept of management of organizational information. More specifically, it examines the notion of information richness—that phenomenon by which certain individuals are better able to acquire, process and utilize information than are other individuals in the organization. Based on an analysis of relevant research findings some tentative hypotheses relating management and organizational information richness are suggested. In conclusion, a number of managerial implications of the notion of organizational information richness are discussed.  相似文献
