When taking part in the everyday practices of the school, the pupil ‘metalearns’ implicit institutional knowledge about educability and its proper criteria. The aim of this study was to examine one important school practice, self-assessment: How is self-assessment ‘taught’ to children, what is assessed through the self-assessment method, how is self-assessment introduced to children, and how do they perceive those situations? The ethnographic research focused on the classroom situations of one class of first-graders during one autumn term. The data were collected by means of regular observation, video recordings, short interviews, documents, and informal conversations with the teachers, pupils and parents. The findings indicated that the frequency of self-assessment episodes was particularly high in the domains of writing, mathematics, and social skills and behaviour; self-assessment situations were a ‘natural’ part of everyday teaching practices. According to our observations, the result of the self-assessment was considerably explicit. The teacher made sure that the pupils assessed their performance in the way she wanted. The teaching of self-assessment also teaches the child what assessment criteria the school regards as important and how well the child fulfils these criteria. According to our analysis, these important assessment criteria are objectiveness (compliance to standard), honesty, and individuality (a product that ‘looks like’ its author). The children practised self-assessment actively and were apparently capable of assessing their own performance. Our results suggest that ‘the self’ in self-assessment is paradoxical: you can assess yourself as long as you assess the right things in the right way.  相似文献

A novel three-dimensional eye tracker is described and its performance evaluated. In contrast to previous devices based on conventional video standards, the present eye tracker is based on programmable CMOS image sensors, interfaced directly to digital processing circuitry to permit real-time image acquisition and processing. This architecture provides a number of important advantages, including image sampling rates of up to 400/sec measurement, direct pixel addressing for preprocessing and acquisition, and hard-disk storage of relevant image data. The reconfigurable digital processing circuitry also facilitatesin-line optimization of the front-end, time-critical processes. The primary acquisition algorithm for tracking the pupil and other eye features is designed around the generalized Hough transform. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and head movement (six degrees of freedom), and thus provides the basis for many types of vestibulo-oculomotor and visual research. The device has been qualified by the German Space Agency (DLR) and NASA for deployment on the International Space Station. It is foreseen that the device will be used together with appropriate stimulus generators as a general purpose facility for visual and vestibular experiments. Initial verification studies with an artificial eye demonstrate a measurement resolution of better than 0.1° in all three components (i.e., system noise for each of the components measured as 0.006° H, 0.005° V, and 0.016° T. Over a range of ±20° eye rotation, linearity was found to be <0.5% (H), <0.5% (V), and <2.0% (T). A comparison with the scierai search coil technique yieldednear equivalent values for the systemnoise and the thickness of Listing’s plane.  相似文献

The aim was to study coping strategies among hearing-impaired individuals by using a validated coping instrument—The Ways of Coping Questionnaire (WOCQ; S. Folkman & R. Lazarus, 1988)—and to relate the use of coping with anxiety sensitivity and experience of hearing impairment. A questionnaire booklet was sent out to the members of the local branch of the Swedish Hard of Hearing Association. Ninety-four members responded to the questionnaire, yielding a 53% response rate. Primary outcome measures were the WOCQ, the Anxiety Sensitivity Index, and visual analogue scale rating of discomfort from hearing impairment. Repeated measures analysis of WOCQ subscales showed that the participants used planful problem solving and self-controlling coping strategies whereas escape/avoidance responses were less frequently used than the other coping strategies. Anxiety sensitivity was associated with escape/avoidance coping (r = .63, p < .0001). In conclusion, hearing-impaired individuals do not use escape/avoidance coping more than other coping strategies. However, escape/avoidance coping is associated with anxiety sensitivity, suggesting that sensitivity to anxiety sensations is an important associated factor. Coping strategies were not associated with discomfort from hearing impairment in any meaningful way.  相似文献

In this study, we investigated the prevalence of women's sexual aggression against men and examined predictors of sexual aggression in a sample of 248 women. Respondents reported their use of aggressive strategies (physical force, exploitation of a man's incapacitated state, and verbal pressure) to make a man engage in sexual touch, sexual intercourse, or oral sex against his will. Childhood abuse, gender role orientation, ambiguous communication of sexual intentions, level of sexual activity, and peer pressure were included as predictors of sexual aggression. Almost 1 in 10 respondents (9.3%) reported having used aggressive strategies to coerce a man into sexual activities. Exploitation of the man's incapacitated state was used most frequently (5.6%), followed by verbal pressure (3.2%) and physical force (2%). An additional 5.4% reported attempted acts of sexual aggression. Sexual abuse in childhood, ambiguous communication of sexual intentions, high levels of sexual activity, and peer pressure toward sexual activity were linked to an increased likelihood of sexual aggression. The findings are discussed in relation to the literature on men's sexual aggression.  相似文献

The authors report about the clinical implementation of music therapy in psychosomatic hospitals in FRG based on a survey among practising music therapists: attending especially to the qualification of music therapists, their integration and the problem of indication. The coverage of music therapy in the standard textbooks on psychosomatic medicine is discussed.Finally the state of research on music therapy in psychosomatic hospitals is reviewed.  相似文献

Virtual reality (VR) promises methodological rigour with the extra benefit of allowing us to study the context-dependent behaviour of individuals in their natural environment. Pan and Hamilton (2018, Br. J. Psychol.) provide a useful overview of methodological recommendations for using VR. Here, we highlight some other aspects of the use of VR. Our first argument is that VR can be useful by virtue of its differences from the normal perceptual environment. That is, by virtue of its relative non-realism and poverty of its perceptual elements, it can actually offer increased clarity with respect to the features of interest for the researcher. Our second argument is that VR exerts its measurable influence more by eliciting an acceptance of the virtual world (i.e., ‘suspension of disbelief’) rather than by eliciting a true belief of the realism of the VR environment. We conclude by providing a novel suggestion for combining neuroimaging methods with embodied VR that relies on the suspension of disbelief.  相似文献
