This paper reports a study of the views of teachers and Examination Board staff on the introduction of individual investigative work into pre‐university (Advanced level) Chemistry courses in England. The move towards investigative work at this level represented a significant change in emphasis in the nature of assessed practical work in pre‐university courses, and was initially a feature of only two courses, the Salters’ Advanced Chemistry course and the Cambridge Modular Science course. In this study, data were collected through the use of interviews with selected teachers of the two courses, and also with key staff in the relevant Examinations Boards. The findings of the study suggest that both teachers and Examination Board staff view the move towards investigative work at this level as having a number of benefits for students, though teachers reported some difficulty with their joint roles of teacher and assessor.  相似文献

在数字图书馆向智慧图书馆的“数智跨越”过程中,需要探讨并明晰智慧图书馆的主要特征。本文以元分析思维方式整合智慧图书馆理论与实践探索,提出数字图书馆向智慧图书馆转型的三个特征:“智能”特征体现为技术资源“硬智能”和人力资源“软智能”的集成;“智识”特征体现在对智慧图书馆内容建设的认识,以及通过智慧图书馆的“软智能”与用户达成共识;“智见”特征体现于结合人工智能(AI)应用的数字人文和虚实互补的元宇宙取向。智慧图书馆作为连通数字人文和图书馆元宇宙的AI实体形态,将会成为闪耀在未来智慧世界中的明珠。图2。表1。参考文献31。  相似文献

Traditional research on collaborative learning employs a “black box” approach that makes it difficult to gain a deeper understanding of the differential effects of collaborative learning. To make the black box transparent, researchers have studied the process of collaboration, in order to establish which interaction features are likely to make learning more effective and efficient for group members. Although cognitive load theory has been developed in the context of individual learning situations, it may provide a promising new way of looking inside the black box, assuming that students working in groups have more processing capacity than students working individually. The aim of this article is to provide an overview of the process-oriented and cognitive-load approaches to conducting collaborative learning research, to highlight their respective advantages and disadvantages, and to suggest how they can be combined in order to address new research questions.  相似文献

Abstract The velocity and acceleration at which the ball-carrier or tackler enters the tackle may contribute to winning the contest and prevailing injury free. Velocity and acceleration have been quantified in controlled settings, whereas in match-play it has been subjectively described. The purpose of this study was to determine the velocity and acceleration of the ball-carrier and tackler before contact during match-play in three competitions (Super 14, Varsity Cup, and Under-19 Currie Cup). Using a two-dimensional scaled version of the field, the velocity and acceleration of the ball-carrier and tackler were measured at every 0.1 s to contact for 0.5 s. For front-on tackles, a significant difference (P??0.05) were evident. Also, the ball-carrier's velocity over the 0.5 s was relatively stable compared with that of the tackler. Results suggest that tacklers adjust their velocity to reach a suitable relative velocity before making contact with the ball-carrier.  相似文献

Factors contributing to parents' decision when they choose between cochlear implantation (CI) and traditional hearing aids for their child were examined. The subjects were children with severe/profound hearing loss, born 1999-2001, registered in the universal neonatal hearing screening program in the Flanders region of Belgium. Qualitative data collected retrospectively from parents were subjected to thematic content analysis. In their responses to professional advice, parents were segmented into 3 groups: (a) those whose primary considerations were the importance of oral language development and the relative potential of CI and traditional hearing aids; (b) those for whom alternative factors (e.g., medical risks, ethical issues) were paramount, even in the face of professional advocacy of CI; (c) those who followed professional advice against CI. The researchers conclude that care professionals should be sensitive to the impact of their advice and other factors in parental decision making.  相似文献

The impact of early physical and sexual abuse (EPA/SA) occurring in the first 5 years of life was investigated in relation to depressive and internalizing symptomatology and diurnal cortisol regulation. In a summer camp context, school-aged maltreated ( n  =   265) and nonmaltreated ( n  =   288) children provided morning and late afternoon saliva samples on 5 consecutive days. Child self-report and adult observer reports of child internalizing and depressive symptoms were obtained. Children experiencing EPA/SA and high depressive or internalizing symptoms uniquely exhibited an attenuated diurnal decrease in cortisol, indicative of neuroendocrine dysregulation. These results were specific to EPA/SA rather than later onset physical or sexual abuse or early occurring neglect or emotional maltreatment.  相似文献
