JALIS专题数据库的调查分析与对策思考     

段梅  赵晖 《图书馆建设》2010,(5)

专题数据库的建设是JALIS重点建设的三类资源之一。通过对JALIS三期专题数据库的建设情况调查可以得出结论:JALIS专题数据库建设具有主题丰富、参与面广、多个建库平台并存等特点,但也存在建设能力参差不齐、数据量偏少、数据库规模小、数据更新维护滞后等问题,应采取协作策略、推广策略与服务策略等相关策略加以解决。  相似文献

面授辅导课在高校英语网络教学中的应用研究     

蔡静  李晋荣 《远程教育杂志》2006,(6):63-69

面授辅导课在网络教育中被认为是支持学生自主学习的手段之一,在本质和功能上均有别于校园教育中的课堂教学。本研究以北京外国语大学网络教育学院开设的英语技能课程——“高级职业英语”和英语知识课程——“跨文化交际”为例,旨在调查建构主义所倡导的以学生为中心、基于学习任务的教学方法在网络教育面授辅导课中的实现程度、课程类型对实施此娄教学方法的影响及学生对它的反映和评价。研究方法包括调查问卷和统计学分析。研究结果表明：1.网络教育中学生对面授辅导课的需要和重视程度不容忽视;2．课程类型影响学生对面授辅导课的期望、教师的授课方法和学生评价面授辅导课的参考标准;3.作为自主学习的支特手段,面授辅导课在指导学习方法、培养学习能力、评估学习效果和提供情感支持等方面的功能还未得到师生两方面的充分认识和挖掘,研究者在此基础上为如何更好地发挥面授辅导课的助学功能提出了几点建议。  相似文献   

Meeting the highly qualified teachers challenge     

Kok-Aun?TohEmail author  Boon-Tiong?Ho  Joseph?P.?Riley  Yin-Kiong?Hoh 《Educational Research for Policy and Practice》2006,5(3):187-194

The moulding of the future of a nation depends on the teachers and the education they provide in schools. Research evidence from the US. National Assessment of Educational Progress (NAEP) confirms this to be the case. Quantitative analysis of data indicates that measures associated with pre-service teacher preparation are by far the strongest correlates of student achievement (Darling-Hammond 2000). The research report of Wilson, Floden, and Ferrini-Mundy (2001) also suggests a strong relationship between teacher preparation and teacher effectiveness. Other research studies similarly indicate that differences in teacher quality are the most crucial for student achievement when compared with variables such as class size, streaming, or the amount of homework (Anderson & Helms 2001; Mendro 1998; Powell & Anderson 2002; Rivkin, Hanushek & Kain 2001; Saunders & Horn 1994; Strong & Tucker 2000) as possible contributory factors. In the pursuit of improved student achievement, we therefore need to examine seriously the role of teacher variables, ranging from teacher qualifications and their subject matter knowledge, to what motivates them to take up teaching as a career and as a consequence, how they teach in classrooms.  相似文献

画面主体位置布局的眼动实验及对网络视频资源建设的启示     

曹卫真  车笑琼  祁禄  刘海涛 《远程教育杂志》2013,(5):97-106

在视频画面中传递信息的主要对象是画面主体,画面主体能否引起学生的注意,注意的持久性如何直接影响着学生的学习效果。在归纳"井"形构图的基础上,通过对教学视频画面主体位置的统计发现,教学视频画面中的主体位置普遍以"三分法构图"形式存在。采用心理学研究手段与方法(眼动实验法),研究画面"三分法构图"中主体位置对学生注意的影响,结果显示,主体位于画面中间更能吸引学生的注意力,学生观察画面根据一定的顺序进行的,不同专业学生的眼动指标有差异。  相似文献   

Narrative construction of teacher identity: positioning and negotiation     

Hava Greensfeld 《Teachers and Teaching》2013,19(5):527-551

This study investigates the ways in which the disciplines of science and literature influence concepts related to thinking among teachers at colleges of education. Tools were developed to distinguish between what teachers declared to be important in the thinking skills necessary for their discipline and the skills the teachers actually used. A quantitative and qualitative analysis was carried out of the findings. Thinking skills unique to each discipline and common thinking skills were found. The study revealed the discrepancy between the declared views of thinking skills held by teachers and their active use. Results of this research can help build an environment that develops a culture of thinking among both teachers and future teachers in educational colleges.  相似文献   

Crowdsourcing mode-based learning activity flow approach to promote subject ontology generation and evolution in learning     

Qi Wang  Guozhu Ding 《Interactive Learning Environments》2013,21(7):965-983

ABSTRACT

Subject ontology can help implement the structured organization of knowledge for online learners and thus plays an important role in the learning process. However, building ontologies by experts is time-consuming, and the adaptation of such ontologies to different contexts might be a problem. Crowdsourcing, which allows users to build and refine ontologies during their learning process, has exhibited potential for solving this problem. In this study, a crowdsourcing mode-based learning activity flow approach is proposed to guide the learning of online learners while promoting the generation and evolution of subject ontologies using the learners’ contributions to the learning content. This flow makes full use of the learners’ wisdom during the learning process to promote self-regulated learning as well as the generation and evolution of the ontology. Based on the proposed approach, a learning support system was developed and an experiment conducted involving a Chinese lesson on “The Liangzhou Poem”. In the experiment, student participants built 722 triples, of which 584 evolved as formal items in the subject ontology. Moreover, all learners were able to construct a well-organized knowledge graph. Students in both high- and low-scoring groups contributed valuably to the knowledge generation and evolution of the subject ontology. Furthermore, while the widths of the knowledge constructed by students in high- and low-scoring groups were similar, their depths were substantially different. During this process, the crowdsourcing-based activity flow system achieved satisfactory technique acceptance, which means that the proposed approach and system are useful for the effective generation of subject ontologies while helping learners acquire knowledge.  相似文献
