ABSTRACTThis article discusses issues concerning the spread of data-driven educational technologies in Brazil. Here, as elsewhere, educational technology continues to be promoted optimistically as the bearer of a panacea for historically-rooted social problems. Whilst some of these technologies have indeed contributed to important widening-participation programmes in the last two decades, widespread advocacy of technological ‘solutionism’, reflected in gradually stronger policy demands for efficiencies to be improved through ‘innovation’, has supported a relentless marketisation of the country’s educational systems. As transnational corporations position themselves to take control of key areas of these systems, threatening to restructure the whole sector, data-driven educational technologies provide the latest example in a series of ‘new’ ideas offered in an ever-expanding market. Based on the notion of ‘conceptual metaphors’, which encapsulate specific ways of perceiving, thinking and relating with the world, this article examines key metaphors underpinning discourses surrounding data-driven educational technologies in Brazil. In particular, the article analyses ways in which these specific metaphors may be promoting perspectives that ignore difference and obscure broader questions concerning education, thus contributing to the reproduction of previously existing problems and supporting new forms of colonisation. 相似文献

ABSTRACTThe paper presents a theorisation of pedagogic knowledge formation, as a continuous attempt to understand the positions in discourse we occupy. The paper documents some participatory practitioner research by teacher educators centred on a course development initiative for student teachers of English, at an English university. Students researched their experiences of becoming a teacher within a course that was largely school-based, whilst their tutors researched their own involvement in the process (the main focus of this paper). Drawing on Lacanian theory, tutors are depicted as learning subjects having more or less certainty or doubt about the knowledge they possess. In attempting to understand this interplay of certainty and doubt, tutors arrive at stronger conceptualisations of learning. Through this approach, the paper provides a theoretically informed conception of professional knowledge, as involving a process of renewing ideas about learning, in meeting or resisting external demands. 相似文献

This study sought to determine the prevalence of mildly retarded children in a sample of 312 primary school classes (N (pupils) = 8,967). Schools were chosen at random from each of the eight Psychological Service districts of metropolitan Auckland; all Grade 2‐5 classes in the sample schools were included in the investigation. Eighty percent of the teachers surveyed believed they had one or more mildly retarded children in their classes, yielding an overall prevalence rate of 8.04 percent (N = 721). Approximately one‐third of the children designated as mildly retarded were considered by their teachers to be not coping academically as well as socially, but of these 75 percent had not been referred for special educational consideration. Comparisons among the eight districts revealed that prevalence/referral rates and characteristics of identified/referred children did not differ significantly across districts. Results are discussed in terms of their policy implications for the identification and referral of mildly retarded children in need of special educational services. 相似文献
