基于学习者行为特征的MOOCs学习伙伴推荐

大规模开放在线课堂的兴起给高等教育的全球化提供了契机。与大规模参与用户形成鲜明对比的是,目前课程普遍存在完成率不足的问题。造成学生退出的原因之一是学习者缺乏合适的学习伙伴相互交流以及时解决学习中遇到的问题。分析了开放课程中论坛用户的身份特征和学生用户在论坛讨论过程中的行为模式,建立了学习者行为特征模型和学生在讨论过程中形成的关系网络。根据课程内容建立关键词词典,并以此为主题词,提出了一种具有固定主题词的主题模型,进而推断关系网络潜在的主题分布,最终根据主题分布结果为学习者推荐学习伙伴。通过分析Coursera课程平台的真实数据,证明了该学习伙伴推荐方法能有效地挖掘出主题相关的学习者,为学习者相互推荐学习伙伴,在一定程度上将有助于提高学习者的积极性。

面向个性化课程推荐的分层分期注意力网络模型

随着大规模在线开放课程（MOOC）平台的广泛使用，需要一种有效的方法为用户推荐个性化课程。针对现有的课程推荐方法通常利用课程学习记录为用户的学习兴趣建立整体的静态表示，但忽略了学习兴趣动态变化与用户短期学习兴趣的问题，提出一种分层分期的注意力网络（HPAN）进行个性化课程推荐。该网络的第1层利用注意力网络得到用户的长短期学习兴趣，第2层将用户的长短期学习兴趣和短期交互序列相结合并通过注意力网络得到用户的兴趣向量；然后计算用户兴趣向量与每个课程向量的偏好值，据此为用户进行课程推荐。在XuetangX（学堂在线）公开数据集上的实验结果表明，与次优的序列分层注意力网络（SHAN）模型相比，HPAN模型的Recall@5提高了12.7%，与FPMC(Factorizing Personalized Markov Chains)模型相比，它的MRR@20提高了15.6%。HPAN模型的推荐效果优于对比模型，可解决实际的个性化课程推荐。

一种结合用户适合度和课程搭配度的在线课程推荐方法

在线学习由于不受时空限制而愈来愈流行.如何从成千上万的在线课程中选择合适课程是在线学习者面临的极大挑战,在线课程推荐应运而生.但现有课程推荐系统仍面临2个主要问题：1)不同用户具有不同的学习能力和需求.因此,需要仔细考虑用户对不同课程的适合度,否则可能会导致推荐的课程难度太大.2)目前的课程推荐方法忽略了推荐课程与用户已学课程之间存在的可搭配关系,可能导致不合适的推荐.针对以上2个问题,首先深入分析了用户的学习特征、类型及其对不同课程的学习适合度;同时,利用课程的共同被选频率,对不同课程之间的可搭配关系进行探究.基于以上2个方面,提出了一种结合用户适合度和课程搭配度的课程推荐模型(user-suitability and course-matching aware course recommendation model, SMCR).在CN(canvas network)数据集和MOOC(massive open online courses)数据集上进行的对比实验结果表明,该方法可以达到更高的推荐准确性,而且SMCR模型能够向用户推荐既适合其学习又与其已学课程可以进行搭配的课程.

Factors impacting students' online learning experience in a learner‐centred course

Technologies bring a new era of content presentation for online teaching and learning. With more instructors adopting new tools to design online teaching materials, students are often put into learning contexts with certain new design components. Assessing learner experience and outcome in these contexts is challenging because of the complexity involved, as social and individual factors and behavioural impacts of using the new components have to be considered. Few studies have been reported in the literature identifying behavioural factors of learners' online learning experience when they interact with the content. Factors that affect learners' online learning experience, especially the affect factors, are less understood. This study therefore proposed and tested a model that explains the relationships among the affect factors and outcome behaviours of participants' online learning experience, taking into account individual difference, and employing a comparison based on a difference in content presentation. The data were collected from a professional training course offered by a university in the United States. The results support the assumption that time spent in study affects learning outcome and other outcome related behaviours. Also, positive relations between perceived quality of content design and outcome behaviour were found, indicating the effects of sense of presence and feeling of enjoyment on performance of creative tasks. The study intends to foster a deeper understanding of motivation and behaviours of online learning under innovative content design.

Using cognitive load theory to structure computer‐based learning including MOOCs

A massive, open, online course (MOOC) is a form of computer‐based learning that offers open access, internet‐based education for unlimited numbers of participants. However, the general quality and utility of MOOCs has been criticized. Most MOOCs have been structured with minimal consideration of relevant aspects of human cognitive architecture and instructional design principles. This paper suggests cognitive load theory, with its roots embedded in our knowledge of human cognitive architecture and evolutionary educational psychology, is ideally placed to provide instructional design principles for all forms of computer‐based learning, including MOOCs. The paper outlines the theory and indicates instructional design principles that could be used to structure online learning and to provide an appropriate base for instructional design when using computer‐based learning.     

Exploring extraneous cognitive load in an instructional process via the web conferencing system

This study, based on an online instruction via the web conferencing system, explores extraneous cognitive load and its influence on the learning process. Sixty-two sophomore students who enrolled in an online introductory programming course participated in the study. An observation form was used to analyse the course records in video format. Interviews with selected participants were conducted in order to clarify the students’ behaviours during the instructional process. The results indicated that the extraneous cognitive load elements (coherence, redundancy, modality, signalling, and temporal-spatial contiguity) influenced the instructional process. The results suggested that, in web conferencing systems extraneous cognitive load appeared not only from design features of multimedia materials but also the delivery settings. Future work is needed to put forward the influences of the load elements caused in various platforms. The implications and suggestions for instructors who plan to design and teach online courses via web conferencing were also provided.

A dynamic analysis of the interplay between asynchronous and synchronous communication in online learning: The impact of motivation

With the increased affordances of synchronous communication tools, more opportunities for online learning to resemble face‐to‐face settings have recently become available. However, synchronous communication does not afford as much time for reflection as asynchronous communication. Therefore, a combination of synchronous and asynchronous communication in e‐learning would seem desirable to optimally support learner engagement and the quality of student learning. It is still an open question though, how to best design online learning with a blend of synchronous and asynchronous communication opportunities over time. Few studies have investigated the relationship between learners' actual use of synchronous and asynchronous communication over time. Therefore, this study addressed that relationship in an online course (N = 110), taking into account student motivation, and employing a dynamic inter‐temporal perspective. In line with our assumptions, we found some support for the expected association between autonomous motivation and engagement in asynchronous and synchronous communication, be it restricted primarily to the first course period. Also, positive relations between engagement in synchronous and asynchronous communication were found, with the strongest influence from using asynchronous to synchronous communication. This study adds to the knowledge base needed to develop guidelines on how synchronous communication can be combined with asynchronous learning.

The effect of reflective learning e-journals on reading comprehension and communication in language learning

This study focused on the use of reflective learning e-journals in a university web-based English as a foreign language (EFL) course. In the study, a multimedia-based English programme comprising fifteen different units was delivered online as a one-semester instructional course. Ninety-eight undergraduate students participated, and they were divided into two groups: the treatment group used reflective learning e-journals, while the control group completed content-related exercises. The study investigated the effects of reflective learning e-journals and how students used them to aid learning. Results show that when learning from web-based instruction, students who used reflective learning e-journals outperformed students who did not do so in terms of reading comprehension. Using reflective e-journals improved the academic performance of learners in the online course. In addition, journal writing students claimed that they also improved their organisational skills and writing abilities through their reflective learning e-journal writing and found the journal writing to be a very helpful tool in reviewing the course and preparing for the exam.
