课程内容研究的新视野——TIMSS课程分析工具“主题追踪图”的演进与启示     

张新宇  袁智强  占小红 《比较教育研究》2011,(1):76-80

美国密歇根州立大学施密特教授等人研究开发并完善的TIMSS"主题追踪图"作为重要的整体性课程分析工具,其使用的建模方法有效弥补了传统研究方法的不足。本文通过检索"主题追踪图"的演变轨迹,认为基于该工具的国际课程比较能全面反映各国课程在主题选择与组织层面的异同,而构建的课程连贯性理想模型更是提供了一种全新的课程内容研究思路与范式。  相似文献

Relational Maintenance in the Digital Age: Implicit Rules and Multiple Modalities     

Jen Eden  Alice E. Veksler 《Communication quarterly》2016,64(2):119-144

The present project utilized a mixed methods approach to examine how individuals use CMC to maintain proximal relationships. Nine different communication channels were examined concurrently to elucidate how frequently mediated relational maintenance is used and to examine what participants reported in terms of motives for use and avoidance of particular channels. Findings indicate that participants in proximal relationships are hyper-aware of the amount of intimacy implied by a particular communication channel and strategically engage channels to suit their needs. We propose that relationships will be difficult to maintain if people violate the implicit rules that appear to govern channel selection.  相似文献

QTL analysis for some quantitative traits in bread wheat     

Pushpendra KG  Harindra SB  Pawan LK  Neeraj K  Ajay K  Reyazul RM  Amita M  Jitendra K 《Journal of Zhejiang University. Science. B》2007,8(11):807-814

Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits taken together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through marker aided selection.  相似文献
