This paper reports the experiences of 150 children and six primary teachers when active learning pedagogies were introduced into the first year of primary schools. Although active learning increased the amount of talk between children, those from socio‐economically advantaged homes talked more than those from less advantaged homes. Also, individual children experienced very little time engaged in high‐quality talk with the teacher, despite the teachers spending over one‐third of their time responding to children's needs and interests. Contextual differences, such as the different staffing ratios in schools and pre‐schools, may affect how well the benefits of active learning transfer from pre‐school contexts into primary schools. Policy‐makers and teachers should pay particular attention to the implications of this for the education of children from economically less advantaged home backgrounds. 相似文献

One captive adult chimpanzee and 3 adult American black bears were presented with a series of natural category discrimination tasks on a touch-screen computer. This is the first explicit comparison of bear and primate abilities using identical tasks, and the first test of a social concept in a carnivore. The discriminations involved a social relationship category (mother/offspring) and a nonsocial category involving food items. The social category discrimination could be made using knowledge of the overarching mother/offspring concept, whereas the nonsocial category discriminations could be made only by using perceptual rules, such as “choose images that show larger and smaller items of the same type.” The bears failed to show above-chance transfer on either the social or nonsocial discriminations, indicating that they did not use either the perceptual rule or knowledge of the overarching concept of mother/offspring to guide their choices in these tasks. However, at least 1 bear remembered previously reinforced stimuli when these stimuli were recombined, later. The chimpanzee showed transfer on a control task and did not consistently apply a perceptual rule to solve the nonsocial task, so it is possible that he eventually acquired the social concept. Further comparisons between species on identical tasks assessing social knowledge will help illuminate the selective pressures responsible for a range of social cognitive skills. 相似文献

Three vocational high schools provide illustrative and contrasting histories in terms of African-American education and economic opportunity. Washburne Trade School reinforced trade union exclusion of African-Americans, and since integration in the 1960s has been abandoned by most of the powerful unions. Dunbar Vocational High School directed African-Americans into the lower-paying trades, but has lost the economic base that the ghetto once provided. Chicago Vocational School prepared the white working class for industrial jobs, but integration and re-segregation has coincidentally seen the erosion of Chicago's manufacturing base. These schools are compared in the economic, political, and cultural contexts of past and present. It is proposed that an integrated strategy for the reform of vocational education is necessary for these schools to adapt to economic change in the present and future. 相似文献
