While a large amount of interest has been shown in the use of peer and self‐assessment, few studies have considered the effect of stress on the students involved. None have considered whether the resultant stress itself might account for any noticeable improvements in student performance. The research presented in this paper addresses this question. An experimental design measured the effects of type of assessment and gender on student stress levels and performance. Results suggest that females are more stressed by self‐assessment than males and that being subjected to self‐ and peer assessment, while more stressful, leads to improved student performance in summative tasks. 相似文献

What makes a good educator? The relevance of meta programmes 总被引:1,自引:0,他引:1
Nigel Brown 《Assessment & Evaluation in Higher Education》2004,29(5):515-533
This paper reports the results of a qualitative study which explores the relevance of meta programmes to students' perceptions of teaching quality. Meta programmes are a model of personality preferences from the discipline of Neuro Linguistic Programming (NLP). Research into teaching effectiveness indicates that students rate as important ‘hygiene factors’ such as the teacher's ‘knowledge of the subject’ as well as less tangible qualities including ‘ability to communicate’ and ‘student–teacher rapport’. This study reveals the need for similar qualities but, in some cases, presence of these ‘hygiene factors’ was insufficient; students cited other factors related to personality. Some students were found to like the approach of certain teachers whilst other students rated the same teachers less favourably. When questioned as to why, factors emerged that relate to the distinct teaching style adopted by these teachers that appeared to suit particular students and not others. This study suggests that a teacher's meta programmes influence the approaches adopted in their teaching and these styles suit students with matching meta programme preferences. Where students have different meta programme preferences from the teacher, then, even where the ‘hygiene factors’ are met, this leaves the student dissatisfied. There is potential for teachers to adopt teaching approaches more appropriate for the meta programme profiles of their students. Also, on the part of the students, an increased awareness of their meta programme preferences offers the potential to improve their learning experience. 相似文献

Five experiments are reported establishing the poisoned partner effect (PPE) in rats as a robust phenomenon and indicating some of the factors that control its occurrence. Experiment 1 was a replication of Lavin, Freise, and Coombes (1980) and demonstrated that the PPE could be obtained under the conditions they described. Experiment 2 established that the PPE was not due to sensitization. Experiment 3 indicated that the nonpoisoned partner (NPP) had to be familiar with its poisoned partner in order for the PPE to be observed. Experiment 4 established that, under the conditions employed here, the NPP and its sick partner had to be paired together for at least 30 min following poisoning of the latter for the PPE to occur. Finally, Experiment 5 demonstrated that the NPP and its poisoned partner had to be paired together immediately following the poisoning episode. If 40 min or more was allowed to elapse following poisoning before the two were placed together, the PPE was attenuated. Taken together, these results indicate that the time course of the PPE is similar to that of the effects of the poisoning agent and suggest that some stimulus secreted by the poisoned rat and associated with the administration of the poison is the causative factor in the PPE. 相似文献

The XVII 2002 Commonwealth Games held in Manchester, England, was the first major international multi-sport event to include elite athletes with disabilities (EADs) in its main sports programme and medal table. In this exploratory article we seek to examine some of the complex issues surrounding the inclusion of EADs in the Manchester Games by analysing the coverage afforded those athletes by six national British newspapers. The results suggest that: (1) there was a tendency by the British media to discuss the performances of EADs in terms more-or-less consistent with a medicalized understanding of disability; (2) the inclusion of EADs in the Games signalled the ‘end of a sporting apartheid’ between ‘able-bodied’ athletes and EADs; and (3) that the participation of EADs in the Games was said to reflect the alleged growing ‘inclusion’ of people with disabilities in the wider society more broadly. The paper concludes by discussing some of the unintended consequences of including EADs in the Games, including those brought about by the classification system used to group athletes into events according to their particular impairment. Those which were associated with the supposed need for greater media coverage of EADs in ‘able-bodied’ sports competitions such as the Commonsealth Games. 相似文献

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage. 相似文献

This research presents the way in which children from a Nahua indigenous community build representations of the Earth’s shape, as well as the process that causes day and night. Concepts from school and local culture were studied. For the first case, a questionnaire was applied to 331 children, out of which 38 children were then interviewed on the topics from the questionnaire. For the cultural ideas, three teachers from the region and 30 children from the sample were interviewed. The results show that the representations depend on the form of questioning and the existence of three models: a flat structure with a celestial dome and mechanisms that hide or remove the Sun or the Moon in order to create day and night; a spherical structure with a surrounding sky, where the Sun and Moon rise and set; and a transitional model with a hollow sphere, flat surface and celestial dome. Cultural ideas do not appear to have any influence over these models, probably due to a loss of the community’s cosmogonic knowledge and the age of the children. 相似文献

An experiment was conducted with 30 postgraduate students to discover how they might go about learning from an 'ideal' computer-based environment. A system was created which preserved the appearance of a computer-based interaction, yet which freed itself from the constraints of current technology. The students, although not aware of this at the time, were in fact interacting with two human experts, backed up with appropriate documentation and computer files, via a computer screen. The results suggest a number of different learning strategies linked to relatively successful and less successful learning. Implications for the design of computer-based learning materials are discussed. 相似文献

The reunification of Germany, and the transformation of early childhood services in East Germany offers a unique opportunity to explore how abrupt policy changes affect service providers and service users. East Germany had extensive coverage for children under three and near universal coverage for children 3‐6. After reunification these services were drastically reduced, and the ideological justification for them was systematically rejected. This process is illustrated by a discussion of the changes in practice which took place in two nurseries in East Berlin, and the reactions of staff to the changes they were required to make. 相似文献
