Counselors (N = 911) reported the research skills needed for practice and subsequent research training needs. Findings indicate that counselors have a high need for research skills at work, but training needs differ significantly by counselor type. Recommendations include increasing emphasis on single‐case design, survey design, and widely available data analysis tools.  相似文献

At the turn of the 21st century a methodological analysis of the planetary development of civilization became a topical issue in world science. Such an analysis is based on a framework of categorical concepts adopted for active use in globalistics, namely, the biosphere, sociosphere, technosphere, noosphere, and infosphere. The given context provides a new perspective on the phenomenon of information and informatics, with the latter having experienced increasing demands as a popular scientific discipline in the field of information. In the contemporary setting, these phenomena can be adequately evaluated only in connection with the above concepts.  相似文献

This article is the third in a series reporting on the changes in attitudes and interests‐‐mainly with respect to physics‐of several hundred students as they proceed through the Danish upper secondary school (Gymnasium). It concentrates on the results of the final investigation which took place shortly before the students leave the school.  相似文献

Attention disorders in the school population include attention deficit, hyperactivity and conduct disorders. A key concept for distinguishing hyperactive from attention disorders is behavioural inhibition as advocated by Barkley, a prominent American researcher. However, the concept itself needs to be understood because, as argued in this paper, there are two kinds of inhibition: Pavlov's original concept and the American one. These should be differentiated if the abnormal conditions associated with attention and hyperactivity are to be rationally connected to cognitive characteristics, rather than to be solely based on clinical symptoms and behavioural ratings. We suggest a consensus on the concept of inhibition and a unified view of attention disorders integrating cognitive and behavioural manifestations. Finally, the importance of basing remediation on a theoretically supported and rationally derived set of cognitive training tasks for the amelioration of inattention and hyperactivity is offered.  相似文献
