For a decade or so there has been a new ‘hype’ in educational research: it is called educational neuroscience or even neuroeducation (and neuroethics)—there are numerous publications, special journals, and an abundance of research projects together with the advertisement of many positions at renowned research centres worldwide. After a brief introduction of what is going on in the ‘emerging sub‐discipline’, a number of characterisations are offered of what is envisaged by authors working in this field. In the discussion that follows various problems are listed: the assumption that ‘visual proof’ of brain activity is supposedly given; the correlational nature of this kind of research; the nature of the concepts that are used; the lack of addressing and possibly influencing the neurological mechanism; and finally the need for other insights in educational contexts. Following Bakhurst and others, a number of crucially relevant philosophical issues are highlighted. It is argued that though there are cases where neuroscience insights may be helpful, these are scarce. In general, it is concluded, not a lot may be expected from this discipline for education and educational research. A reminder is offered that the promise of neurophilia may be just another neuromyth, which needs to be addressed by philosophy and education. 相似文献

Educational assessment involves eliciting, transmitting, and receiving information concerning the level of proficiency of a learner in a specified domain. With that in mind, it is perhaps surprising that the literature seems to make very little use of the signal processing metaphor. The present article begins by making a general case for greater use of this metaphor, as a simple and intuitive thinking tool for helping to explain how educational assessment works. The main body of the article extends this argument by demonstrating the utility of the metaphor in helping to explain how educational assessment can go wrong. During the 1980s and 1990s, Samuel Messick extensively discussed two major ways in which educational assessment can go wrong via construct-irrelevant variance and construct underrepresentation, respectively. Despite their importance, these concepts have had only a limited impact on the literature. Part of the reason for this may be a lack of clarity and comprehensiveness in their articulation. The present article aims to articulate these concepts more clearly and comprehensively, within a framework provided by the signal processing metaphor, reconfiguring them as signal contamination and signal deficiency, respectively. 相似文献

Summary The four-year Phase II of the action-research programme "Indigenous Soil and Water Conservation in Africa (ISWC II) started in December 1996 and operates in the French-speaking countries Tunisia, Burkina Faso and Cameroon and in the English-speaking countries Ethiopia, Uganda, Tanzania, and Zimbabwe. It had received a budget-neutral extension from the funders (Netherlands Development Aid, DGIS) for the entire 2001. This paper is based on the Participatory Technology Development (PTD) experiences with the ISWC II project in Cameroon. The ISWC II project aimed to improve the effectiveness of both indigenous and modern Soil and Water Conservation (SWC) practices through a process of joint experimentation involving farmers, scientists and development agents. The authors have developed the informal and formal strategies used and their impacts in the process of the institutionalisation of the PTD approach in Cameroon. 相似文献

Children prefer learning from, and affiliating with, their racial in‐group but those preferences may vary for biracial children. Monoracial (White, Black, Asian) and biracial (Black/White, Asian/White) children (N = 246, 3–8 years) had their racial identity primed. In a learning preferences task, participants determined the function of a novel object after watching adults (White, Black, and Asian) demonstrate its uses. In the social preferences task, participants saw pairs of children (White, Black, and Asian) and chose with whom they most wanted to socially affiliate. Biracial children showed flexibility in racial identification during learning and social tasks. However, minority‐primed biracial children were not more likely than monoracial minorities to socially affiliate with primed racial in‐group members, indicating their in‐group preferences are contextually based. 相似文献

The purpose of this study was to compare the effects of two practical precooling techniques (skin cooling vs. skin + core cooling) on cycling time trial performance in warm conditions. Six trained cyclists completed one maximal graded exercise test (VO2(peak) 71.4 +/- 3.2 ml x kg(-1) x min(-1)) and four approximately 40 min laboratory cycling time trials in a heat chamber (34.3 degrees C +/- 1.1 degrees C; 41.2% +/- 3.0% rh) using a fixed-power/variable-power format. Cyclists prepared for the time trial using three techniques administered in a randomised order prior to the warm-up: (1) no cooling (control), (2) cooling jacket for 40 min (jacket) or (3) 30-min water immersion followed by a cooling jacket application for 40 min (combined). Rectal temperature prior to the time trial was 37.8 degrees C +/- 0.1 degrees C in control, similar in jacket (37.8 degrees C +/- 0.3 degrees C) and lower in combined (37.1 degrees C +/- 0.2 degrees C, P < 0.01). Compared with the control trial, time trial performance was not different for jacket precooling (-16 +/- 36 s, -0.7%; P = 0.35) but was faster for combined precooling (-42 +/- 25 s, - .8%; P = 0.009). In conclusion, a practical combined precooling strategy that involves immersion in cool water followed by the use of a cooling jacket can produce decrease in rectal temperature that persist throughout a warm-up and improve laboratory cycling time trial performance in warm conditions. 相似文献
