我国网络远程课程十年研究综述     

胡志金 《现代远程教育研究》2011,(2):33-39

网络远程课程,即网络课程与远程课程的合称。自2000年以来,我国网络远程课程研究已走过10年（2000—2009）历程,已有研究在课程内涵、课程设置、课程设计、课程开发、课程建设、课程实施和课程评价等方面都存在不同进展与不足。基于开放本质的整体设计和基于成人特色的学教设计,是课程设计的两大方向;课程开发中课程设计与课程理念、课程设置的研究存在脱节现象;目前课程建设的整体规划、教学设计水平有待提高,优秀资源共享程度较低;课程实施中缺乏实施机制和实效研究,不注重研究成果转化;课程评价则存在评价指标和量化标准上重复研究的情况,评价的目的多为评质定级而不是反馈改进。当前网络远程课程的发展需要具有全程、综合、以“学”为中心的研究视野,树立动态的、学科开放的、学习开放的网络远程课程观,建立专业化的团队,注重试验研究,注重研究成果的及时转化。  相似文献

What makes a skilled writer? Working memory and audience awareness during text composition     

Denis Alamargot  Gilles Caporossi  David Chesnet  Christine Ros 《Learning and individual differences》2011,21(5):505-516

This study investigated the role of working memory capacity as a factor for individual differences in the ability to compose a text with communicative efficiency based on audience awareness. We analyzed its differential effects on the dynamics of the writing processes, as well as on the content of the finished product. Twenty-five graduate students composed a procedural text explaining how to assemble a model turbine. They were free to consult a documentary source, featuring captioned pictures of turbine parts and assembly steps, at any time. Graphomotor and eye movements were recorded using ‘Eye and Pen’ software with an eye-tracker and digitizing tablet. Results showed that high WM capacity writers used a different strategy to explore the visual source, making longer writing pauses and producing more detailed procedures, and achieved the communicative goal more efficiently, by introducing more reader supports. In conclusion, we discuss the feasibility of audience awareness training.  相似文献   

An investigation of Taiwan University students' perceptions of online academic help seeking, and their web-based learning self-efficacy     

Kun-Hung Cheng  Chin-Chung Tsai 《The Internet and Higher Education》2011,14(3):150-157

This study was conducted to investigate Taiwan University students' perceptions (including experience, confidence and preference) of online academic help seeking (OAHS) and students' level of web-based learning self-efficacy (WLSE). Two instruments, OAHS questionnaire, consisting of information searching, formal and informal query scales, and WLSE questionnaire, including general and functional scales, were then validated through collecting the responses from 300 university students. Results indicate reciprocal relations between experience, confidence and preference in students' online academic help seeking behaviors. Students' academic help seeking behaviors were related to their general self-efficacy in a web-based course setting. Students' functional WLSE was related to their perceptions of information searching for OAHS. Findings of this study also imply that students' experience of seeking help from informal online channels is prominent when they participate in a web-based course.  相似文献

Socioeconomic Status– and Gender‐Based Differences in Students’ Perceptions of E‐Learning Systems     

Leslie Jordan Albert  Camille S. Johnson 《Decision Sciences Journal of Innovative Education》2011,9(3):421-436

Many universities are pursuing increases in on‐line course offerings as a means of offsetting the rising costs of providing high‐quality educational opportunities and of better serving their student populations. However, enrollments in online courses are not always sufficient to cover their costs. One possible way of improving enrollments is through marketing campaigns targeted to specific demographic groups. In this study, we take a first look into how students’ perceptions of e‐learning systems, prior to their enrollment in an online course, vary across socioeconomic status and gender. Findings suggest that prior to taking an online course, working‐class students perceive e‐learning systems more positively than their middle‐class peers but that little difference exists between genders. Armed with this knowledge, universities may improve online course enrollments by marketing online courses specifically to working‐class students or through campaigns aimed at improving middle‐class students’ perceptions of e‐learning systems.  相似文献

王薇 《天津师范大学学报(社会科学版)》2011,(5)

租界社会与近代天津新闻事业的发展密切相关。租界的移民社会为报刊发展提供了广泛的读者群;租界繁荣的商业环境培植了传播媒介的生长点;租界内传播渠道的多样化与先进的传播手段,提升了媒介传播速度。九国租界的存在,为近代天津新闻事业提供了发展契机和相对有利的客观环境。  相似文献   

数据移动技术的选择与实现     

卜鸥 《乐山师范学院学报》2003,18(4):111-113

数据移动技术是分布式数据库中非常重要的技术之一。本归纳总结了分布式数据库中的数据移动技术，从本质上将现有的数据移动技术分为在线、同步、复制三类技术。在线技术系统可以达到绝对的一致性，但该技术对网络要求很高，且在节点较少时才比较有效。同步技术可以支持大量节点，异构和级联环境，要求有效的网络连接，存在一定的一致性延时。复制技术比较灵活，支持大量节点，异构和级联环境；可以在较好的网络环境，也可以在无直接或网络环境恶劣的情况下使用；存在一定的一致性延时，也可达到准实时的一致性。这三类数据移动技术的应用和选择，主要取决于业务需求和可用的技术架构以及系统对一致性和延时的要求。  相似文献   

Using stakeholder feedback to improve online professional development opportunities     

Rhonda N. T. Nese  Paul Meng  Sarah Breiner  Erin Chaparro  Robert Algozzine 《Journal of Research on Technology in Education》2020,52(2):148-162

Abstract

Traditional professional development is often characterized as being expensive, time consuming, and lacking impact. In contrast, online professional development provides greater flexibility and is becoming increasingly popular for school personnel. In this article, we report the process and outcomes of gathering feedback to adapt traditional in-person to online training differentiated for the participants to maximize utility, efficiency, and effectiveness in meeting the needs of key stakeholders. Focus groups were conducted with teachers, administrators, and other specialists to gather feedback on content as well as how online learning modules (OLMs) could be tailored to meet specific school site and team needs. We discuss our findings in the context of continuing efforts to improve general and specific professional development opportunities.  相似文献   

Enhancing the facilitation of online groups in higher education: a review of the literature on face-to-face and online group-facilitation     

Glyn Thomas  Stephen Thorpe 《Interactive Learning Environments》2019,27(1):62-71

There still appears to be a gap between what online learning promises and what it can deliver in terms of student learning. Developments in online pedagogies and professional learning appear to lag behind the developments in technology and the promised benefits of technological transformation may not be realised. In this paper, we bring together perspectives that highlight vital aspects of online group-learning by reviewing the group-facilitation literature and the latest online learning literature to interrogate the pedagogical theories and practices currently used in online group-learning in higher education. We specifically focus on the interpersonal interactions between teachers and students, which are described in the online learning literature using the terms instructor immediacy, teaching presence, and social presence. We note differences in the literature regarding how teacher presence is interpreted and enacted and we expound the importance of the personal characteristics of the online teacher. Finally, we provide some signposts that might help course designers and teachers to improve online group learning: the intentional use of effective online learning pedagogies; a deeper understanding of what constitutes teacher presence; and strategies to enact that teacher presence with online groups. Recommendations for further research in online group facilitation are provided.  相似文献
