This article reports on a case of participatory self-directed online learning within the context of a graduate-level instructional technology course. The course was about online learning environments and relied on both asynchronous and synchronous technologies. In this case, the instructor and students engaged in collaborative course design through one of the assignments where student teams and the instructor led one week’s worth of course activities and discussions. This article begins with a discussion of the literature on participatory self-directed online learning. Then, the article presents an overview of the course design, detailed discussion of the assignment that framed student participatory self-directed learning and two examples of student assignments. The framing question for organising this case was as follows: What lessons can a team of graduate students and the instructor learn about self-directed participatory online learning from a collaborative design project? The article ends with the overall lessons learned from the case and implications to future design of online activities. 相似文献

Researchers have identified three approaches to learning—surface, strategic, and deep. These approaches are influenced by various contextual and student factors, including teaching methods, assessments, and relevance to future career. The global objective of this study was to explore the influence of course elements and students’ emotional connection to section content on students’ approaches to learning in an introductory Food Science and Human Nutrition course. Students completed two questionnaires for the Nutrition and Health (NH) and Composition and Chemistry (CC) course sections: (a) Entwistle's ASSIST Inventory and (b) a questionnaire developed to assess students’ perceived usefulness of assignments, learning resources, and emotional connection to section content. Students’ approaches to learning did not significantly differ between NH and CC sections, with the majority reporting use of strategic or deep approaches. Generally, positive correlations were obtained for learners who used the deep and strategic approaches and their perceived usefulness of assignments and learning resources. In stark contrast, negative correlations were identified for learners who used the surface approach and their perceived usefulness of learning resources and assignments. Regarding emotional connection to section content, compared to learners who used the deep and strategic approaches, learners who used the surface approach did not enjoy and felt anxious about learning the content in both sections. Furthermore, based on regression analysis, the surface learning approach was a predictor for low exam scores in both sections. Based on these findings, instructors should implement practices in course design, instructional methods, and assessment strategies that help students choose deep and strategic approaches to learning, while minimizing surface approaches. 相似文献

With the rapid development of online learning platforms, learners have more access to various kinds of courses. However, they may find it difficult to make choices due to the massive number of courses. The main contribution of our research is the design of a course recommendation framework which extracts multimodal course features based on deep learning models. In this framework, different kinds of information of course, such as course title, and course audio and course comments, are used to make proper recommendation in online learning platforms. Moreover, we utilize both explicit and implicit feedback to infer learner’s preference. Based on real-world datasets, our empirical results show that the proposed framework performs well in course recommendation, achieving an AUC score of 79.03%. This framework can provide technical support for course video recommendation, thus helping online learning platforms to manage course resources and optimize user learning experience. 相似文献

A synchronous blend of online learning and “face-to-face” teaching is becoming a feasible instructional approach in higher education with the advent of technology. Although this learning mode is not new in higher education, little research has been done to contextualise social presence experiences in which effects of interactions were explored for enhancing learning. A qualitative approach was adopted using the case study method to examine the instructor and students’ pedagogic interactions in the social presence of a blended synchronous learning environment. This paper reports an exploration of the blended learning with an online group of students at a remote site attending a computer-aided engineering drawing course synchronously with a face-to-face group taught by an instructor in a laboratory. The process of interaction was visually and verbally mediated by videoconference as if in an online face-to-face learning community. The findings show that the online and face-to-face groups had different social presence experiences in which interaction emerged. Emotional adaptation and practice is needed for the students and the instructor in such a complex environment. Based on the interaction patterns, a framework of interactions in the blended synchronous learning environment is conceptualised to inform course development and instructional design. Implications for further study are also discussed. 相似文献

Summary The current shift to mediated and WWW-based teaching and learning requires both teachers and learners to adapt established classroom practice to the new online environment. Many of the electronic systems currently on offer fail to support the complexity of interaction necessary to facilitate deep learning. This paper identifies the instructional strategies or “micro-genres” that form the essence of successful classroom teaching, and describes an online system, WebTeach(tm), that attempts to provide structured teacher-learner interactions that build on the familiar activities and strategies of the classroom. Through access to these “micro-genres” in an online classroom, both teacher and learner can reduce the cognitive demands of learning new processes while focusing on strategies for deep learning related to the content of the course. 相似文献

参与式学习和网络教学法 总被引：1，自引：0，他引：1
人们对新学习机会的需求持续增长以及新的信息系统和通讯技术不断涌现,使得在线学习成为了教育实践中的中心话题。我们有必要建立一个框架,使那些有着不同文化、语言背景的远程学生产生有意义参与学习的经验。我们使用新术语“Cybergogy“来描述建立在线参与式学习所采用的策略,描述了为不同背景的远程学生创设认知、社会和情感三方面的学习经验。Cybergogy的核心是参与式学习,在参与式学习中学生自己确立学习目标、探索适当的资源、与其他人进行小组协作并以有意义的方式建构知识。我们所建立的“参与式学习的cybergogy模型“包括三个相互重叠/交叉的域:认知域、情感域和社会域。这一模型综合了当前的思想、观念和理论框架,它们是关于学生参与在线学习的这三个域上的程度和性质的。教师可以利用这一模型来描述每个学习者,然后设计针对每个人的策略,我们称这一过程为“customized engagement“。这样,学生不仅有机会实现自己的学习目标,而且将积极地参与学习过程。 相似文献

The rapid growth of online courses in higher education has led to developments in the field of e-assessment. This paper presents a study, which examined the quality of online academic courses using a multidimensional assessment of students' activities and perceptions, using educational data mining and an online questionnaire. The assessment focused on four aspects: instructional, communication, course workload and overall learning experience. The course instructional model was found well-structured. The video lectures, assignments and materials designed for the online course were the most used and contributing learning resources. However, the number of students who entered the video lectures decreased as the course progressed. Low activity was found in the discussion forums. Students perceived the course workload as low. Overall, the learning experience was high and the students were highly satisfied. These findings provide insights that may assist in improving the quality of future online courses. 相似文献

As online education continues to grow, instructors from traditional classrooms are being asked to design online courses. In this study, data from interviews with thirty-three public four-year college and university instructors, who had experience designing online courses, were used to understand the instructor’s perspective on online course design. Using grounded theory, data were analyzed, sorted, and coded to uncover the strategies instructors use to design online courses. Results revealed instructors adapt to the online environment by using strategies to mimic elements of face-to-face courses: in essence, adaption comes through assimilation. Instructors expressed interest in helping students navigate online to encourage active participation in courses. They described using technology and learning management system (LMS) features (e.g., videos, discussion forums) to “hear” and “see” students, as a way to increase interaction and presence, familiar elements from face-to-face education. They spoke of creating authentic assignments to increase student engagement. The implications of this study include effective design and instructional strategies for online courses, as well as understanding the motivation of instructors who design online courses. The study results are relevant to a broad audience including online instructors, instructional designers, LMS organizations, and administrators. 相似文献

AbstractMassive open online courses (MOOCs) offer opportunities for professional development of environmental educators globally, yet we lack understanding of participants? cognitive and social learning processes and of how instructors can enhance these processes. Based on the Community of Inquiry framework, we used a survey and coded participant discussion board and Facebook posts to examine the cognitive, social, and teaching presence in the Environmental Education: Transdisciplinary Approaches to Addressing Wicked Problems MOOC, offered by Cornell University. Rather than train educators in a specific curriculum, the goal of the MOOC is to expand educators? critical and transdisciplinary thinking about the field of environmental education and to enhance social interactions to support learning, educators, and knowledge co-creation. Results indicate that cognitive presence is higher on the discussion board whereas social presence is higher on Facebook. Over half of cognitive posts focused on exploration, a lower level of learning, whereas just less than a fifth reflected higher level integration, suggesting room for enhancing cognitive learning. Our results suggest strategies to encourage higher levels of thinking and more meaningful social interactions to foster learning, educator support, and co-creation of knowledge, thereby improving online professional development. 相似文献
