Abstract This article argues that because of the practice in the 1960s of placing black children in so-called ‘educational subnormal’ units there is now a reluctance to look at the speci?c needs of African Caribbean children. The post-Warnock politics of integration/inclusion following this period point to the ‘institutional racism’ of schools and white teachers to explain poor exam results. This article argues that in the current political climate which prioritizes ‘inclusion’ we should not patronize the black child. There is a need to position the factors of oppression equally with other factors of underachievement; to re-employ psychological, behavioural and educational tools as well as to deconstruct school processes and teacher attitudes; and to consider psychosocial factors related to underachievement without forgetting the reality of institutional racism. The article illustrates a research project that looks at the pastoral needs of African Caribbean children. It points to these needs as the key variable in unlocking their underachievement at school. 相似文献

This sub‐study is part of a longitudinal naturalistic investigation monitoring the social behaviour of young children (3‐8‐year‐olds) before and after the arrival of broadcast television in St Helena, South Atlantic. Children's free‐play behaviour in first school playgrounds was videotaped in 1994 (pre‐tv), and in 1995 and 1996 (post‐tv), and then coded and analysed by trained observers. Findings showed no significant differences in children's behaviour either across the availability of broadcast television (i.e. CNN) or with the addition of further channels (CNN plus others). 相似文献

In education, as in all other fields, grassroots practitioners need people with sharp, creative minds who are able to question accepted ideologies and challenge current practice. Such innovators stimulate argument and collaboration which, in turn, lead to the development of new philosophies and to more enlightened and effective practices. In this paper it Is argued that in special education, however, the philosophical models of integration which have been presented over the last eight years have often inadvertently inhibited, rather than promoted, the Introduction of more effective learning systems. 相似文献

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument. 相似文献

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The findings suggest that translational research between the different areas could benefit professionals across domains. 相似文献

This article considers the extent and nature of student participation in a trade bargaining simulation from a community of practice perspective. This third‐year economics module included a blend of online communication (through email, online chats and online discussions) and face‐to‐face meetings, both in smaller bargaining groups and in whole class plenary meetings. Our method of analysis includes the use of Exchange Structure Analysis of text chats and face‐to‐face learning conversations, triangulated by observation, survey and interview data. The focus on community of practice enables us to offer a nuanced interpretation of differences in crude participation data derived from the online chats. Superficially, the data may suggest marginalisation of participants, but Wenger's (1988 ) notion of peripheral participation with a trajectory towards full participation reframes the disparities in terms of an active community of practice. Some members are fully engaged with the practices of trade bargaining from the early stages of the simulation, while others move towards full participation over the duration of the simulation. Our results suggest that the laboratory‐based online text chats did provide opportunities for student participation in the simulation, and that male and female students exhibited different patterns of participation in the chats. 相似文献

Higher education is under increasing pressure to re‐evaluate the place of practice in its programs and there are increasing demands for workplace‐based experiences to be built into undergraduate degrees. The paper reports on an extended responsive case study conducted in the School of Criminology and Criminal Justice at Griffith University between 1994 and 2004. The findings point towards a model that can be used to develop courses based around a set of key challenges that learners need to face, criteria for the university’s construction of worthwhile activities, and principles of procedure that are required in order to implement them. It is suggested that university curriculum planners should concentrate on a process model of teaching, learning and research rather than on the more traditional models that tend to treat knowledge as a commodity and emphasise its production, transmission and delivery. 相似文献

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed. 相似文献
