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   

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   

高校学报编排规范调查分析     

林锋 《许昌学院学报》2005,24(5):154-156

通过对高校学报发表的论文中中文摘要、关键词、英文翻译、中图分类号和参考文献等5个项目执行《CAJ—CD规范》的调查,结果表明：中文摘要和关键词的规范化情况很差,英文翻译、中图分类号和参考文献的规范化情况相对较好,办刊时间较长的本科学报规范化情况比办刊时间较短的本科学报和专科学报好,高校学报整体规范化情况不理想．分析了产生这种现象的原因,并提出改进措施,以提高学报编排的规范化水平．  相似文献   

Using stakeholder feedback to improve online professional development opportunities

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

Developing a communal identity as beginning teachers of mathematics: Emergence of an online community of practice   总被引：1，自引：0，他引：1  

Merrilyn E. Goos  Anne Bennison 《Journal of Mathematics Teacher Education》2008,11(1):41-60

The aim of this study is to investigate how a community of practice focused on becoming a teacher of secondary school mathematics emerged during a pre-service teacher education programme and was sustained after students graduated and began their first year of full-time teaching in schools. Bulletin board discussions of one pre-service cohort are analysed in terms of Wenger’s (1998) three defining features of a community of practice: mutual engagement of participants, negotiation of a joint enterprise, and development of a shared repertoire for creating meaning. Emergence of the online community was associated with our own role in facilitating professional dialogue, the voluntary and unstructured nature of participation, initial face-to-face interaction that created familiarity and trust, and the convenience of using email rather than logging on to a website. The study shows that the emergent design of the community contributed to its sustainability in allowing the pre-service and beginning teachers to define their own professional goals and values.
