This paper aims at exploring the challenges arising when teachers at secondary school level decide to cooperate about students’
argumentative writing. Two teams of teachers and researchers have met regularly during the school year, discussing students’
texts from a variety of disciplines. Going into two writing tasks in detail, the authors discuss the importance of scaffolding (support) in the teaching of argument. The paper includes a discussion of some specific textual features that are often touched
upon in the meetings. 相似文献

Research on vulnerability factors among ethnic groups, independent of primary psychiatric diagnosis, may help to identify groups at risk of suicidal behavior. French African Caribbean general psychiatric patients (N = 362) were recruited consecutively and independently of the primary psychiatric diagnosis. Demographic and clinical characteristics and lifetime history of suicide attempts were recorded. Sixty‐five patients (18%) had a history of at least one suicide attempt. Presence of professional qualifications, children, poor social contacts, treatment with benzodiazepine at inclusion, and poor treatment compliance were all associated with a lifetime history of suicide attempts. 相似文献

Movement activity of a normal baboon and of a baboon with induced Parkinsonism by unilateral administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was recorded by the Walter Reed Activity Monitor (or actigraph). Mean activity in the lesioned baboon was 41% less than that of the nonlesioned baboon measured over a 14-day period. In addition, the daily maximum activity value was significantly less in the MPTP-treated baboon. Moreover, resting and sleeping periods were 30% greater in the lesioned animal. The akinesia and resting and sleeping periods were displayed by the lesioned baboon throughout the day, whereas the control baboon showed them only at night. The data representing summarized movement activity are in accordance with observations of bradykinesia, hypokinesia, and akinesia of the MPTP-treated baboon. The actigraph was well tolerated by the animal because its small size and weight made it largely unobtrusive. We suggest that the actigraph is an appropriate device for measuring motor activity in nonhuman primates. 相似文献

Two samples of subjects (ntot = 22) scoring high or low on EPI-E tapped a morse-key as fast as possible over a 2-min period. As predicted, extraverts showed a lower tapping performance than introverts with differences between groups increasing significantly over time due to greater delays among the extraverts. Within the E dimension tapping differences could be shown to depend significantly only on the subfactor impulsiveness but not on sociability. There were no differences between groups, however, in frequency of involuntary rest pauses. Therefore the effects of extraversion on tapping performance should be explained more in terms of underlying differences in cortical arousal level than in terms of intermittent blocks as part of inhibitory potentials. 相似文献
