Students’ engagement with two-dimensional (2D) representations as opposed to three-dimensional (3D) representations of anatomy such as in dissection, is significant in terms of the depth of their comprehension. This qualitative study aimed to understand how students learned anatomy using observational and drawing activities that included touch, called haptics. Five volunteer second year medical students at the University of Cape Town participated in a six-day educational intervention in which a novel “haptico-visual observation and drawing” (HVOD) method was employed. Data were collected through individual interviews as well as a focus group discussion. The HVOD method was successfully applied by all the participants, who reported an improvement of their cognitive understanding and memorization of the 3D form of the anatomical part. All the five participants described the development of a “mental picture” of the object as being central to “deep learning.” The use of the haptic senses coupled with the simultaneous act of drawing enrolled sources of information that were reported by the participants to have enabled better memorization. We postulate that the more sources of information about an object, the greater degree of complexity could be appreciated, and therefore the more clearly it could be captured and memorized. The inclusion of haptics has implications for cadaveric dissection versus non-cadaveric forms of learning. This study was limited by its sample size as well as the bias and position of the researchers, but the sample of five produced a sufficient amount of data to generate a conceptual model and hypothesis. 相似文献

Information about how success and gender affect students' views of ideal and actual classroom role behavior can help both researchers and teachers better understand classroom components such as achievement and curriculum. A 20-item double Q sort was used to measure differences in perceptions of high school science students according to letter grades and gender. Individual Q sort item rankings of 160 students were tested for significant differences according to letter grade received; item ratings were compared according to gender for 215 students. Differences in perception according to success were found for both ideal and actual behavior; 8 and 5 items, respectively, out of each 20-item sort were found to be significant at the p = < 0.05 level. No such overall patterns of difference in view were found between boys and girls, although three ideal student items and one actual self-report item were found to be significantly different at the p = < 0.05 level. 相似文献

The education welfare service: the case for a review in England 总被引:1,自引:1,他引:0
Ken Reid 《Educational studies》2008,34(3):175-189
The only major review of the education welfare service (EWS) took place in 1973 when the role and responsibilities of the service were very different from those of today. Recent legislative changes, the influence of the Children Act 2004 and revised public needs of the service, including new multidisciplinary and interdisciplinary frameworks, suggest that an up‐to‐date review would be timely. It may also help to professionalise the service in a number of different ways, something which is long overdue. This paper provides both the rationale and evidence for making the case for a major review of the EWS based on a reading of all key relevant documents and participation in a range of local and national evaluations on the role of the EWS in England and Wales. The major issues which need to be reviewed are identified and a way forward is suggested. 相似文献

Structured document retrieval makes use of document components as the basis of the retrieval process, rather than complete documents. The inherent relationships between these components make it vital to support users’ natural browsing behaviour in order to offer effective and efficient access to structured documents. This paper examines the concept of best entry points, which are document components from which the user can browse to obtain optimal access to relevant document components. It investigates at the types of best entry points in structured document retrieval, and their usage and effectiveness in real information search tasks. 相似文献

Informed Consent in the Study of On-Line Communities: A Reflection on the Effects of Computer-Mediated Social Research 总被引:2,自引:0,他引:2
Elizabeth Reid 《The Information Society》1996,12(2):169-174
In studying on-line communities, researchers must consider the unique environmental factors involved in order to minimize potential harm to human subjects. In particular, the often commented upon disinhibiting effect of computer-mediated communication can encourage people to agree to or even insist on a kind of public exposure by which they may eventually be harmed. On the Internet, where perceptions of interpersonal affect and effects may be obscured by the nature of the medium itself, care must be taken to guard against not only any increased tendency for researchers to objectify subjects, but also the tendency for subjects to underestimate the potential consequences of consent. The criteria for informed consent that may be sufficient in face-toface research environments are not necessarily so in a medium in which subjective experience is easily objectified and information is easily devalued. 相似文献

Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed. 相似文献
