Despite rapid and continued adoption of mobile devices, few learning modes integrate with mobile technologies and libraries' environments as innovative learning modes that emphasize the key roles of libraries in facilitating learning. In addition, some education experts have claimed that transmitting knowledge to learners is not the only educational goal, as cultivating problem-solving skills is also essential. By integrating the problem-based learning (PBL) model with book resources in libraries, one can identify the advantages of libraries in supporting e-Learning, resulting in innovative and valuable research. Therefore, this study presents a novel intelligent mobile location-aware book recommendation system (IMLBRS) with map-based guidance to support cooperative PBL in a real-library environment. Using map navigation and book recommendation functionalities, learners can search for books associated with problem-solving with increased ease and efficiency, thereby helping learners increase their PBL performance in a library environment. Experimental results reveal that learning performance during PBL supported by the proposed IMLBRS for book searches is superior to learning performance during PBL supported by the online public access catalogue (OPAC). Experimental results also show that the proposed system facilitates better learning performance for learners with a field-dependent learning style than for learners with a field-independent learning style. Moreover, the proposed system facilitates learner contemplation, cooperative learning, and library user education as learners interact with a real-library environment and peers during cooperative PBL.  相似文献

This research is aimed to assist individual learners to construct knowledge in online learning through providing them with customized supportive services. The services go beyond simply presenting course materials, but supply a diverse range of technological facilities, tools and services to assist individual learners to progress in the learning process. In this paper, the theoretical background for facilitating construction of knowledge by individual learners is built at the first, through the review of constructivist theories for learning and the objectivist ones. Then, a general conceptual model to describe any number of practices in learning and teaching online is built. It will be used to customize online learning environments to cater for various different learning demands. The services to support the individual’s knowledge construction are identified based on the relevant theoretical background. After that, software agents are proposed to customize the supportive services for individual learners based on their particular learning characteristics. Next, the implementation of these services is investigated and a system prototype is reported. Finally the preliminary research result and the further work are presented.  相似文献

This paper proposes an ontology mapping‐based framewrowrk that allows searching for learning resources using multiple ontologies. The present applications of ontologies in e‐learning use various ontologies (eg, domain, curriculum, context), but they do not give a solution on how to interoperate e‐learning systems based on different ontologies. The proposed solution uses a mapping ontology that is a part of a recent Semantic Web initiative, the Simple Knowledge Organisation System. On top of that, we develop and implement two search algorithms. Finally, we evaluated the solution by developing a system that helps students search for relevant learning resource using a local context (ie, course curriculum) ontology.  相似文献

MOOCs are promising opportunities for lifelong learning, but as promising as these learning opportunities seem, many learners do not succeed in pursuing their personal learning goals. Barriers to learning are the main reason for not finishing the intended (parts of the) MOOCs. This study addressed the question whether the factors age, gender, educational level, and online learning experience affect barriers faced while learning in MOOCs. The results show that it is challenging to combine work and family life with lifelong (online) learning activities, especially for learners in their early adulthood and mid-life. However, more experience with online learning positively affects individuals’ ability to cope with these challenges. Also, learners with a lower educational level may experience a lack of knowledge or difficulties with the course content. These findings may serve as input to inform potentially vulnerable learners about these issues and support them in successfully achieving their personal learning goals.  相似文献

Developing personalised web-based learning systems has been an important research issue in e-learning because no fixed learning pathway will be appropriate for all learners. However, most current web-based learning platforms with personalised curriculum sequencing tend to emphasise the learner preferences and interests in relation to personalised learning services but fail to consider the difficulty level of course materials, learning order of prior and posterior knowledge and learner abilities while constructing a personalised learning path. As a result, these ignored factors thus easily lead to the generation of poor quality learning paths. Generally, learners could generate cognitive overload or fall into cognitive disorientation owing to inappropriate curriculum sequencing during learning processes, thus, reducing the learning effect. With the advancement of artificial intelligence technologies, ontology technologies enable a linguistic infrastructure to represent conceptual relationships between course materials. Ontology can be served as a structured knowledge representation scheme, capable of assisting the construction of a personalised learning path. This study thus proposes a novel genetic-based curriculum sequencing scheme based on a generated ontology-based concept map, which can be automatically constructed by the pretest results of numerous learners, to plan appropriate learning paths for individual learners. The experimental results indicated that the proposed approach could create high-quality learning paths for individual learners. The proposed approach thus can help learners to learn more effectively and to likely reduce learners' cognitive overloads during learning processes.  相似文献

ABSTRACT

This study investigated the effects of an online sharing and feedback programme (OSFP) on preservice teachers’ practical knowledge (PTPK) and attempted to determine the relationship between satisfaction with online interaction and changes in three types of learning preferences (collaborative, competitive and individualistic). In this study, a quasi-experimental pre- and post-test control-group design was employed to examine these factors. The OSFP was designed, focusing on peer interaction on topics regarding field experiences. The analytical results reveal that the OSFP improved practical teaching knowledge, one of the forms of PTPK. Additionally, satisfaction with online sharing and feedback on the topics of interpersonal affairs strengthened preservice teachers’ preference for collaborative learning and decreased their individual preference. Notably, this study demonstrates that collaborative learning preferences positively change when learners are satisfied with online sharing and feedback on the topic of interpersonal affairs.  相似文献

ABSTRACT

Medical education is a domain with fast-changing knowledge and attention to knowledge application and higher order thinking; therefore, how to implement effective teaching is a crucial issue. Based on the technology-based learning model, this study provides a multi-dimensional analysis of published papers on the flipped classroom in medical education from the SCOPUS database, including the form of the learning materials, learning system or player, learning strategies, educational technology, application domains, research issues, participants, and research methods. Based on the results, the application of flipped classrooms in medical education has grown rapidly over the past decade, with the number growing dramatically from 7 papers in 2014, to 16 papers in 2015, and 22 papers in 2016. It was found that a great number of studies adopted instructional videos uploaded on online learning systems or used existing online videos to conduct before-class teaching in the before-class stage of the flipped classroom; moreover, most studies involved no online discussion in the before-class stage. As for learning strategies in the in-class stage, the most frequently adopted strategies were issue discussion, practicing or doing exercises, and problem-based learning. This implies that most studies mainly emphasized basic knowledge understanding and skills training, while little attention was paid to developing learners’ higher order thinking skills. In addition, the majority of studies explored students’ learning interest/satisfaction, learning experience, and performance on the cognitive aspect, while little research was found to investigate their preparation degree or cognitive loading. Based on the review results, this study provides the research trends and potential research issues of flipped medical education to serve as a reference for researchers, instructors, and decision makers.  相似文献

Abstract

The article presents a research study that examined the ways in which digital curation promotes personalized learning, as well as the students’ experiences of this learning process. The study was conducted in the context of K-12 education. Participants spent three months on a project that included curating a personalized digital collection. The study was conducted using a phenomenological qualitative approach for the collection and processing of data. Findings demonstrate that digital curation provides a productive learning activity that supports significant personalized, emotional, and cognitive learning experiences, enabling the curator to construct a personal subject ontology.  相似文献

Understanding how collective attention flow circulates amid an over-abundance of knowledge is a key to designing new and better forms of online and flexible learning experiences. This study adopted an open flow network model and the associated distance metrics to gain an understanding of collective attention flow using clickstream data in a massive open online course. Various patterns and dynamics of attention flow were identified and are discussed here in relation to learning performance. The results show that the effective accumulation, circulation, and dissipation of attention flow are important contributors to academic attainment. Understanding the patterns and dynamics of attention flow will allow us to design cost-effective learning resources to prevent learners from becoming overloaded.  相似文献

This integrative literature review synthesizes the concepts and process of organizational knowledge creation with theories of individual learning. The knowledge conversion concept (Nonaka & Takeuchi, 1995; Nonaka, Toyama, & Byosière, 2001) is used as the basis of the organizational knowledge creation process, while major learning theories relevant to working adult learners are newly synthesized into four types of individual learning processes: adaptive, generative, transformative, and reflective. The results suggest an integrative conceptual flow map of individual and organizational learning facilitated by culture and management system enablers. Implications for using this conceptual framework for practicing performance technology solutions are also discussed.  相似文献

New infrastructures that dramatically change our possibilities for knowledge production and learning have also brought forward ideals on ‘new’ connectivity. Two important ideals of connectivity are that of the individual who tailors his or her knowledge among expansively dispersed resources, and the ideal of access to multiple, diverse resources that provide individuals rich learning opportunities. In order to better understand what cultural norms are implied in our ideals of connectivity, we argue, they must be tested in the crucible of empirical data through the analysis of the actual socio-technical practices of different social and cultural groups. Through a combination of ego-network analysis and a qualitative, in-depth discursive approach, we analyze the networked learning practices of three ethnically different groups in the Netherlands from an extensive research study called ‘Wired Up'. We comparatively describe Dutch youth as ‘unrooted' learners, Moroccan-Dutch youth as ‘routed' learners, and Turkish-Dutch youth as ‘rooted' learners. We propose the idea of the Networked Configuration for Learning as a means to contrast the learning opportunities individuals and groups have in relation to particular offline and online connections, their historical geographies, the development of learning ‘places’, and particular learning affinities.  相似文献

During early childhood, children start developing their cognitive, social, emotional, and behavioural skills, laying the foundation for life-long learning. Cognitive skills are usually taught in traditional classrooms through the use of textbooks and worksheets. The learning content in these textbooks and worksheets is static pre-authored content that is repeatedly used for teaching and learning. This repetition jeopardises the child's learning of individualised and cognitive skills. Preschool cognitive skills learning content comprises facts of everyday life. Similarly, the Semantic Web attempts to model these facts through ontologies. From this, a relationship appears between preschool cognitive skills learning content and the ontologies. The present work focuses on the stated problem and presents the theoretical and development details of a child-friendly tutoring application that dynamically generates cognitive skills learning content using ontologies as domain knowledge. The proposed application was evaluated in a preschool environment for its learning effectiveness and the correctness of the generated content. Three groups of preschool children participated in the study for preschool cognitive skills learning through the use of the proposed application. The first group learned the cognitive skills through the traditional method with textbooks and the teacher's teaching. The second group learned the skills through the proposed application at school in classroom sessions. The third group experienced the proposed application both at school and at home, along with regular classroom sessions. The results show significant gains by the third group over the other two groups, and hence support the use of the proposed application in practice. However, the enhanced learning by the third group disappears if the additional application usage time is removed. Moreover, the results of the expert evaluation show that a great deal of the learning content was correctly generated, thus justifying the true modelling of the domain ontology.  相似文献
