内隐学习理论的研究进展及其对体育教学的启示   总被引:20,自引:1,他引:19  
内隐学习和外显学习是人类学习的两种方式或两种类型,它们平行发生、相对独立,组成一个共生系统.在体育教学领域,运动技能的学习在情境多变、紧张应激、事物结构高度复杂、关键信息不明等条件下以及在技能的保持时间上,内隐学习比外显学习更具优势.内隐学习的研究及其理论提示我们,体育教学必须高度重视并充分开发利用学生的内隐学习潜能.  相似文献

基于领域本体对专利情报知识挖掘的浅析   总被引:1,自引:0,他引:1  
陶然  李晓菲 《情报学报》2008,27(2):212-217
专利作为企业间竞争博弈的重要信息源,通过对其进行深挖掘可以把握竞争对手的技术发展战略以及未来的产品布局,同时还可借助既有专利信息进行产品发明及再创新,故对专利情报进行有效组织和管理,实现隐性知识发现是当今热点问题.通过以实际工作中血管支架专利分析为例,结合对专利情报本身结构的分析,并引入本体理论,同时借助TRIZ和推理机制等概念,初步探讨基于领域本体的专利情报知识挖掘,拟研究一种可以面向专利用户实现智能化情报挖掘体系,从而有效支持专利知识的共享与重用.  相似文献

Millions of Canadians residing in Canada's northern, isolated, rural, and remote communities do not have broadband Internet access. This situation has led to a national “broadband divide.” That is, the deployment of wireline broadband is very limited in Canada's northern, isolated, rural, and remote areas because of the significant expense of installation and maintenance of the wired infrastructure needed to reach dwellings in these locations.Terrestrial broadband wireless technology, on the other hand, does not entail the same kind of physical infrastructure. As a result, there are dramatic changes in how spatial considerations affect the provision of broadband Internet services (BIS) to areas beyond the urban zone. In particular, the spatial question is now focused on assessing the capacity for different technological solutions to reach profitable population bases, and brings to the forefront organizations that are developing non-line-of-sight (NLOS) technologies that would permit wireless Internet access over much greater distances than current solutions.We begin this paper by establishing the importance of broadband connectivity to Canada's northern, isolated, rural, and remote communities. This discussion comments on the role of the Government of Canada in the provision of broadband connectivity to residents of these communities, and outlines the current regulatory issues that govern wireless services and policy formulation.The second part of the paper illustrates the use of geographic information system (GIS) approaches in the study of wireless broadband planning and deployment. Case study findings suggest that GIS applications can make a significant contribution to the analysis of wireless deployment planning, to the understanding of the relationships between wireless signal sources and consumers, and to the spatial configuration of terrestrial wireless broadband networks. We conclude the paper by discussing how the GIS approach employed could be used to inform the public policy process with regard to increasing access to broadband Internet services in all regions of the country, and thereby providing the opportunity for all Canadians, regardless of location, to fully participate in the Information Society.  相似文献

Education researchers, policymakers, and practitioners are concerned with identifying and developing talent for students with fewer opportunities, especially students from historically marginalized groups. An emerging body of research suggests “universally screening” or testing all students, then matching those students with appropriate educational challenges, is effective in helping marginalized students. However, most tests have focused on two areas: math and verbal reasoning. We leverage three nationally representative samples of the U.S. population at different time points that include both novel cognitive measures (e.g., spatial, mechanical, and abstract reasoning) and non-cognitive measures (e.g., conscientiousness, creativity or word fluency, leadership skill, and artistic skill) to uncover which measures would improve proportional representation of marginalized groups in talent identification procedures. We find that adding spatial reasoning measures in particular—as well as other non-cognitive measures such as conscientiousness, leadership, and creativity—are worthwhile to consider for universal screening procedures for students to narrow achievement gaps at every level of education, including for gifted students. By showing that these nontraditional measures both improve proportional representation of underrepresented groups and have reasonable predictive validity, we also broaden the definition of what it means to be “gifted” and expand opportunities for students from historically marginalized groups.  相似文献

Two studies explored the role of the spontaneous use of spatial note-taking strategies (i.e., creating maps and drawings) and spatial ability in learning from a scientific passage. In Study 1, college students read and took notes by hand on a 10-paragraph scientific passage about the human respiratory system. Students tended to use verbal strategies such as lists (on 48% of the paragraphs), outlines (29%) and running text (15%), but also used spatial strategies such as maps (28%) and drawings (11%). Regression analyses indicated that spatial ability and the use of spatial strategies (maps or drawings) significantly predicted learning outcomes, with spatial strategy use explaining additional variance beyond spatial ability. In Study 2, students read the same scientific passage and took notes either by hand on paper (paper group), by hand on a large whiteboard (whiteboard group), or on a laptop computer (computer group). A similar general pattern as Study 1 was found for the paper group, but this pattern was not found for the computer or whiteboard groups, suggesting that the relationships found in Study 1 might depend on the note-taking medium. Results also indicated that students in the paper and whiteboard groups spontaneously used more spatial strategies, whereas the computer group tended to use verbal strategies (i.e., words only), suggesting that different note-taking contexts encourage different strategies.  相似文献

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.  相似文献
