Our aim in this paper is twofold. We wish to describe the work done with families referred for various problems, including child abuse, to one Area Social Services Team (Section 2). We then offer (Section 3) some comparisons to indicate the extent of the problem. The second task in subsequent sections is to use data from various sources on child abuse (Section 4), and our own information (Section 5) to suggest that Army life has inherent features exacerbating risk of child abuse. We make various conclusions, and proposals for improvement (Section 6). We draw material from the Army Welfare Inquiry Committee Report, known as the Spencer Report. 1 We would argue that the welfare of Service families requires special concern.  相似文献

Despite the upsurge in interest in e-learning (or online learning) in Chinese higher education, little is known about the ways in which lecturers design and run their online courses, or about how they perceive e-learning. This paper reports the results of interviews with higher education teachers in China working in conventional, campus-based universities, concerning their conceptions and beliefs of e-learning. The interviews were analysed from a grounded theory perspective that gave rise to seven emerging themes, namely: the ‘centrality of the lecture’, ‘online cooperative learning’, ‘network learning’, ‘student learning’, ‘lecture plus online work’, ‘infrastructure and access’ and ‘professional development’. Discussion of these emerging themes helps us understand the ways in which these teachers think about e-learning and teaching, the beliefs they hold about their ‘e’ practice, the ways in which they implement e-learning, the problems they face in incorporating e-learning into their courses and the ways in which they perceive e-learners. This provides a fascinating and unique insight into e-learning in Chinese higher education. Evidence shows that it is a complex area with many influences, some of which can be attributed to social, cultural and Confucian-heritage factors. It is concluded that, despite enthusiasm by some for innovating e-learning, the dominance of traditional teaching methods in China suggest that the conditions for mainstreaming e-learning in the near future are not strong.  相似文献

Gough and Tunmer’s (1986) simple view of reading (SVR) proposed that reading comprehension (RC) is a function of language comprehension (LC) and word recognition/decoding. Braze et al. (2007) presented data suggesting an extension of the SVR in which knowledge of vocabulary (V) affected RC over and above the effects of LC. Tunmer and Chapman (2012) found a similar independent contribution of V to RC when the data were analyzed by hierarchical regression. However, additional analysis by factor analysis and structural equation modeling indicated that the effect of V on RC was, in fact, completely captured by LC itself and there was no need to posit a separate direct effect of V on RC. In the present study, we present new data from young adults with sub-optimal reading skill (N = 286). Latent variable and regression analyses support Gough and Tunmer’s original proposal and the conclusions of Tunmer and Chapman that V can be considered a component of LC and not an independent contributor to RC.  相似文献

Although clinical educators make an important and irreplaceable contribution to the education of students undertaking qualifications that will enable them to practise as health professionals, little is known about the day‐to‐day experiences of clinical educators and the complexities of clinical education that may contribute to the problems or to the successes of clinical educators. This paper reports on one aspect of a study that sought to increase the understanding and appreciation of the roles and responsibilities of being a clinical educator. The lived experiences of clinical educators in speech pathology 1 1. Also known as speech‐language pathology in North America and speech‐language therapy in the UK. View all notes were explored in depth, over a sustained period of time, in an attempt to understand what it is like to be a clinical educator. This paper uses narrative data to illustrate dilemmas faced by clinical educators in our study, and discusses implications pertinent to clinical educators in a range of health disciplines in higher education.  相似文献

Parallel versions of a new multiple‐choice word‐recognition test were administered to 1019 and 590 Year‐1 pupils respectively. The test format was based on a published test of Word Recognition and Phonic Skills and was intended to provide reliable diagnostic information. It was found that internally consistent measures of three types of word recognition error could be derived (relating to consonants, vowels and phoneme omission), but that scales for letter order errors were unreliable. Information about the length of words which an individual can usually recognise, the proportion of high frequency to low frequency words recognised and the relative ease of recognising regular and irregular words were also considered as having possible implications for teaching. Of these measures, only word length was found to be a strong independent predictor of word recognition. Implications of these findings for the future development of norm‐referenced tests that at the same time provide objective feedback about individual strengths and weaknesses are discussed.  相似文献

The role of analogies in promoting conceptual change in biology   总被引:1,自引:0,他引:1  
Four analogies which were used to teach biology topics by four different teachers were analysed from different theoretical perspectives to determine the key role they had to play in the process of conceptual change. A supermarket analogy for the classification of living things was described using the Posner et al. (1982) view of conceptual change as having the role of a sense maker. A car cooling system analogy for human temperature homeostasis was found to play the role of a memory aid and was best explained by considering Vosniadou's (1994) framework theory and mental models perspective of conceptual change. A fluid mosaic analogy for cell membranes was used by the teacher as a transformer and was best explained by Chi et al.'s (1994) ontological category perspective of conceptual change. Finally, a bucket and pump analogy used to teach the stucture and function of the heart was described as a motivator and was viewed through the motivational perspective of conceptual change of Pintrich et al. (1993). The paper concludes that learning in different situations can best be explained by different perspectives of conceptual change and that these perspectives have much to tell us about the normal shifts in conceptual understanding as well as radical conceptual change.  相似文献

Tolerance to an environmental cold challenge in rats is eliminated when cold exposure occurs in a context different from the adaptation context, indicating that learning mechanisms play a role in thermoregulation (Riccio, MacArdy, & Kissinger, 1991). This finding, analogous to outcomes obtained with drug tolerance, was investigated in the present study. Experiment 1 demonstrated that a change in both proximal and distal contextual cues disrupts an established cold adaptation, an outcome consistent with the view that associative processes contribute to the tolerance. In Experiment 2, although cold tolerance persisted over a 7-day retention interval, the disruption of tolerance by a shift in context was attenuated with the delay of testing. This finding suggests that the precise stimulus attributes of the context were forgotten over the interval. Experiment 3 demonstrated that cold-tolerance disruption is due to the actual change in context and not to novelty of the test context. Experiment 4 showed that changing the context associated with each cold exposure impaired the development of tolerance. The results of these experiments provide additional evidence that cold tolerance is regulated at least partially by associative learning processes.  相似文献
