The BBC has a lasting and massive commitment to education. At a time of difficulty for education and of momentous changes to broadcasting technology and opportunities, it is time to confirm and strengthen that commitment. Among concerns requiring the special attention of educational broadcasting are unemployment and retraining, the ageing population and health care, and ethnic minorities. The opportunities for educational broadcasting in the future can only be enhanced, and certainly not diminished. 相似文献

Does adviser mentoring add value? A longitudinal study of mentoring and doctoral student outcomes 总被引:1,自引:0,他引:1
This study of the impact of doctoral adviser mentoring on student outcomes was undertaken in response to earlier research
that found (a) students with greater incoming potential received more adviser mentoring, and (b) adviser mentoring did not
significantly contribute to important student outcomes, including research productivity [Green, S. G., and Bauer, T. N. (1995).
Personnel Psychology 48(3): 537–561]. In this longitudinal study spanning 5 1/2 years, the effect of mentorship on the research productivity,
career commitment, and self-efficacy of Ph.D. students in the ‘hard’ sciences was assessed, while controlling for indicators
of ability and attitudes at program entry. Positive benefits of mentoring were found for subsequent productivity and self-efficacy.
Mentoring was not significantly associated with commitment to a research career. 相似文献

Preschoolers' ( N = 112) judgments about hypothetical and actual moral and conventional transgressions were examined. Equal numbers of boys and girls at 2 ages (3 and 4 years old) either made judgments about 8 hypothetical moral and conventional transgressions or were interviewed on the same dimensions about 8 naturally occurring moral and conventional transgressions they witnessed in their preschools. Children judged both hypothetical and actual moral transgressions to be more serious, punishable, generalizably wrong, and independent of rules and authority than conventional transgressions. Regardless of domain, hypothetical transgressions were judged to be more wrong independent of rules than actual transgressions, and hypothetical (but not actual) moral transgressions were judged to be more independent of rules than conventional transgressions. 3-year-old girls judged the wrongness of actual moral transgressions to be more independent of authority than did 3-year-old boys. Similar findings were obtained when hypothetical and actual transgressions were matched, and domain differences were still obtained when individual items were examined. Findings are discussed in terms of previous research on preschoolers' conceptions of rules and transgressions. 相似文献

Eating rates (bites per interval) and other meal behaviors (number of chews, sips, talks with a neighbor, and chews per bite) were observed for 30 normal and 30 overweight white preschool children in their school cafeterias. Children were classified according to weight (overweight or normal), age (1 1/2--2 years, 3--4 years, or 5--6 years) and sex. Analysis of variance revealed that overweight preschool children demonstrated a somewhat higher rate of distinctly fewer chews per bite. Boys showed increasing chew rates with increasing age. Talk rates also increased with age but were unrelated to sex or weight status. Sip rates were not significantly associated with age, sex, or weight status. These results support the hypothesis that overweight persons are characterized by an increased eating rate and show that it is apparent even around the time of first self-feeding. 相似文献

This paper is a study on the interaction patterns of distance learners enrolled in the Mathematics and Physics programmes of Universiti Sains Malaysia in the videoconferencing learning environment (VCLE). Interaction patterns are analysed in six randomly chosen videoconferencing sessions within one academic year. The findings show there are more interactions in the graphics display mode than the video display mode. The graphics display mode, which involves the simultaneous interaction of the teacher, students and course materials, shows greater student engagement in the VCLE. The focus on a three-component interaction in distance learning differs from previous studies which looked at distinct types of two-component interactions. The types of communicative interaction, in particular the explanatory and cognitive types which are dominant in the graphics display mode, are discussed within the construct of learning. The higher number of teacher-initiated interactions may also imply that the teacher plays a crucial role in creating and maintaining a community of inquiry focused on exploring and developing content as well as giving feedback on concepts, ideas or solutions. 相似文献

Michael G. Levykh 《Educational theory》2008,58(1):83-101
A bstract . Many recent articles, research papers, and conference presentations about Lev Vygotsky's zone of proximal development (ZPD) emphasize the "extended" version of the ZPD that reflects human emotions and desires. In this essay, Michael G. Levykh expands on the extant literature on the ZPD through developing several new ideas. First, he maintains that there is no need to expand ZPD to include emotions, as its more "conservative" dimensions (cognitive, social, cultural, and historical) already encompass affective features. Second, Levykh emphasizes that an emotionally positive collaboration between teachers and students in a caring and nurturing environment must be created from the outset. Finally, he asserts that culturally developed emotions must mediate successful establishment and maintenance of the ZPD in order to be effective. According to Levykh, Vygotsky's notion that learning can lead development represents a crucial contribution to our understanding of teaching and learning by clearly showing that emotions are vital to human learning and development. 相似文献
