A social recommender mechanism for improving knowledge sharing in online forums     

Yung-Ming Li  Tzu-Fong Liao  Cheng-Yang Lai 《Information processing & management》2012

Nowadays, online forums have become a useful tool for knowledge management in Web-based technology. This study proposes a social recommender system which generates discussion thread and expert recommendations based on semantic similarity, profession and reliability, social intimacy and popularity, and social network-based Markov Chain (SNMC) models for knowledge sharing in online forum communities. The advantage of the proposed mechanism is its relatively comprehensive consideration of the aspects of knowledge sharing. Accordingly, results of our experiments show that with the support of the proposed recommendation mechanism, requesters in forums can easily find similar discussion threads to avoid spamming the same discussion. In addition, if the requesters cannot find qualified discussion threads, this mechanism provides a relatively efficient and active way to find the appropriate experts.  相似文献

Internet Approach versus Lecture and Lab‐Based Approach for Teaching an Introductory Statistical Methods Course: Students’ Opinions     

H. Dean Johnson  Nairanjana Dasgupta  Hao Zhang  Marc A. Evans 《Teaching Statistics》2009,31(1):21-26

The use of the Internet as a teaching tool continues to grow in popularity at colleges and universities. We consider, from the students’ perspective, the use of an Internet approach compared to a lecture and lab‐based approach for teaching an introductory course in statistical methods. We conducted a survey of introductory statistics students. Contradictory to what was hypothesized by the authors, they favoured keeping the lecture and lab‐based approach for teaching the class.  相似文献

Integrating text-to-speech software into pedagogically sound teaching and learning scenarios     

S. D. D. V. Rughooputh  M. I. Santally 《Educational technology research and development : ETR & D》2009,57(1):131-145

This paper presents a new technique of delivery of classes—an instructional technique which will no doubt revolutionize the teaching and learning, whether for on-campus, blended or online modules. This is based on the simple task of instructionally incorporating text-to-speech software embedded in the lecture slides that will simulate exactly the delivery of an intended lecture, assisted with teaching aids such videos, animations and music, as deemed necessary. The benefits of such an approach in the educational system of the University are multifold and can be categorized in three different axes namely pedagogical, administrative and financial. Our main interests in this article lie along the pedagogical benefits (which undoubtedly overlap to some extent into administrative and financial axis) that this technique will bring in the system. While it is obvious that the initial process does consume a reasonable amount of time and gradually reveals its own complexities, constraints and limitations as described in this paper, the approach does however provide considerable elements to bring a major re-definition of the overall teaching and learning framework at the University of Mauritius.

在线学习能力的本质及构成   总被引：1，自引：0，他引：1  

杨素娟 《中国远程教育(综合版)》2009,(5)

在线学习能力是学习者个体的综合素质在在线学习过程中表现出来的、正确驾驭在线学习活动的实际本领、能量和熟练水平,是通过各种渠道培养和完善起来的适应在线学习需求、完成在线学习任务所需要的有效方式,是影响个体发展和在线学业成绩的一种积极的力量.在线学习能力不仅具有认知能力及知识应用能力等一般学习能力的表层表现,而且具有与信息技术能力及学习策略水平、沟通能力、合作能力和个性等非智力因素相联系的深层因素.根据在线学习过程及学习环境与资源的特点,可以重点从五个维度来分析在线学习能力的构成,即元认知能力维度、学习策略水平维度、知识迁移能力维度、信息素养维度及学习资源管理能力维度.其中,元认知能力是构成存线学习能力的基础,学习策略水平和知识迁移能力是在线学习能力的核心,信息素养和学习资源管理能力是保证在线学习成功的重要条件,是开展在线学习不可或缺的能力.  相似文献   

The challenges of online nursing education     

Glenn Gordon Smith  Denise Passmore  Timber Faught   《The Internet and Higher Education》2009,12(2):98-103

To meet the current critical need for qualified nurses, many colleges have initiated online programs, primarily aimed towards registered nurse (RN) to BS students. Despite the growing number of online nursing programs, there is little research on instructor views of online learning. This study used interviews to investigate nursing instructor experiences in online learning. Results revealed instructor concerns with identifying the most effective assessment methods to judge students' ability to apply their lessons in real-world settings. Online nursing exhibits unique challenges, such as providing nursing students with online authentic learning experiences that relate to real-world nursing situations, which comprise both high-stake medical and interpersonal elements. Results also indicated that providing support and ensuring that the faculty have sufficient time to develop effective courses, with adequate assessment for the students, is necessary to ensure the quality of online nursing education.  相似文献   

Weblog Technology for Instruction,Learning, and Information Delivery*     

J. P. Shim  Chengqi Guo 《Decision Sciences Journal of Innovative Education》2009,7(1):171-193

Ever since Weblog emerged as an infusive online communication tool over the last decade, its impacts have been witnessed by the Internet society at large. Meanwhile, more and more universities and colleges are offering online classes enhanced by Web technology. In this article, we investigate the role of Weblog combined with face‐to‐face lectures through a three‐phase study that examines college students' perception of Weblog used in class. Ordinary least squares (OLS) regression and Multivariate Analysis of Variance (MANOVA) techniques are employed to recognize meaningful patterns from collected data. The findings lie in the aspects of: relationship between level of study and the perceived value of Weblog, the relationship between level of Weblog experience and the perceived value of Weblog, and factors contributing to students' perception of Weblog usage. As the first work of its kind examining Weblog adoption from student perspective, this article provides educators, researchers, and practitioners with conceptual and practical references.  相似文献
