Utilizing online learning resources (OLR) from multi channels in learning activities promise extended benefits from traditional based learning-centred to a collaborative based learning-centred that emphasises pervasive learning anywhere and anytime. While compiling big data, cloud computing, and semantic web into OLR offer a broader spectrum of pervasive knowledge acquisition to enrich users’ experience in learning. In conventional learning practices, a student is perceived as a recipient of information and knowledge. However, nowadays students are empowered to involve in learning processes that play an active role in creating, extracting, and improving OLR collaborative learning platform and knowledge sharing as well as distributing. Researchers have employed contents analysis for reviewing literatures in peer-reviewed journals and interviews with the teachers who utilize OLR. In fact, researchers propose pervasive knowledge can address the need of integrating technologies like cloud computing, big data, Web 2.0, and Semantic Web. Pervasive knowledge redefines value added, variety, volume, and velocity of OLR, which is flexible in terms of resources adoption, knowledge acquisition, and technological implementation.  相似文献

Current distance learning systems are increasingly packing highly data‐intensive contents on servers, resulting in the congestion of network and server resources at peak service times. A distributed learning system based on faded information field (FIF) architecture that employs mobile agents (MAs) has been proposed and simulated in this work. The learning contents are decentralised in the proposed system, and these are dynamically distributed around the main education site server on different nodes in response to network congestion and server overload. The system simulation results have been presented and analysed. The proposed system holds the potential to address the network congestion and server‐overload problems in distance learning systems.  相似文献

Librarians are the custodians of library materials. University libraries have a large number of materials in their collections; these collections have different challenges to maintain their existence and utilization. Security and protection of these resources is a difficult task. Book theft or loss is a phenomenon naturally associated with libraries and librarians. This article is an attempt to provide an overview of existing conditions of theft and loss of library material and to describe a major initiative that has been taken to overcome the situation. This study was designed with survey methodology and circulated to library professionals at 172 university and degree awarding institutions. There were 94 responses (54.65%) received. The study revealed that librarians faced objections from auditors and sometimes paid a penalty for stolen or lost books. The theft and loss of materials are examined critically by university management, library committees, and internal and external auditors. Some library professionals are required to pay from their own pockets for stolen and lost material. However, a few librarians write off library books as per Pakistan's Higher Education Commission (HEC) rule. Research highlighted that most libraries have not used technology such as RFID, 3M, or EM Tags for the security of books. An effective technological book security system minimizes loss and provides relief for librarians from audit issues and financial penalties.  相似文献

Information explosion, development and applications of ICTs, changing dynamics of information users, and evolving trends in library and information services have promoted the discussion of continuing education (CE) in Library and Information Science (LIS) domain. ICTs are increasingly changing the landscape of libraries and challenging the traditional prevailing roles of LIS professionals. LIS professionals find it hard to remain in context in this technological era. They require the new set of skills and knowledge to address the challenges and issues of their professional life.The purpose of this study was to explore the opinions of LIS professionals to make an assessment about CE needs and the role of library schools to address these needs. The study opted sequential mixed methods of research. In first phase, an online survey was conducted to meet the objectives of the study. Data was collected by using a structured questionnaire. A total of 144 responses (70% male and 30% female) were received. In 2nd phase, a focus group was conducted to collect the qualitative data. The meta inferences were drawn on the basis of inferences of both QUAN and QUAL strands. The findings of the study revealed that respondents perceive a very active and instrumental role of LIS schools in their continuing education. Workshops, post-master certificate, and post-graduate diplomas were preferred formats of continuing education programs. The respondents preferred week long and 1–6 months long CE programs. In terms of the timings, weekends programs were most preferred. The respondents recommended that course instructor should be based on the contents of the course and a blend of teaching faculty and practitioners may be productive. The study also identified core areas of CE offerings.The findings of the study are helpful for LIS schools, professionals, trainers, funding bodies and policy makers. The study has the potential to bridge the gap by providing insight about the CE needs and recommend the concrete suggestions to act upon.  相似文献

Most accounts of affect and motivation in the science education literature have discussed them as relevant to, but distinct from, disciplinary pursuits. These include Pintrich’s seminal work on affective and motivational factors in learning science (P. R. Pintrich, 1999, 2003; P. R. Pintrich & E. De Groot, 1990; P. R. Pintrich, R. W. Marx, & R. A. Boyle, 1993). Our purpose here is to build on those ideas, drawing as well on accounts of scientists’ practices (e.g., H. E. Gruber, 1974; E. F. Keller, 1983) and of students’ taking up of disciplinary pursuits (R. A. Engle & F. R. Conant, 2002; R. Lehrer, 2009; M. Scardamalia & C. Bereiter, 1991, 2006) to propose that affect and motivation are inherent in the disciplinary practices of science. Thus, we introduce notions of epistemic affect and epistemic motivation, and we illustrate how these are evident in a case study of a student we have followed from 4th to 7th grade. We consider how this perspective aligns with and contributes to research on interest (e.g., S. Hidi, 2006; S. Hidi, K. A. Renninger, & A. Krapp, 2004; C. Sansone, 2009), and we discuss implications for research and instruction in science education. We argue that part of what should happen in the science class is to cultivate students’ feelings and motivations within the discipline.  相似文献

Poor matriculation mathematics results in Bophuthatswana led us to make exploratory efforts to identify possible non-pedagogical factors responsible for such results. Two small scale studies were carried out to examine relationships of socio-personal variables to mathematics achievement. Study 1 looked into the impact of socioeconomic background, school alienation, sex, self-concept and attitude toward mathematics on mathematics performances of secondary school pupils, while study 2 was aimed at examining relationships of dogmatism and mathematics anxiety to mathematics achievement of first-year university students. The data of these two studies invite the attention of mathematics educators to the importance of attitude toward mathematics, mathematics anxiety, and dogmatism in mathematics achievement of Bophuthatswana secondary school and university students.  相似文献

Recent studies have highlighted a fear or difficulty with the study and understanding of neuroanatomy among medical and healthcare students. This has been linked with a diminished confidence of clinical practitioners and students to manage patients with neurological conditions. The underlying reasons for this difficulty have been queried among a broad cohort of medical, dental, occupational therapy, and speech and language sciences students. Direct evidence of the students’ perception regarding specific difficulties associated with learning neuroanatomy has been provided and some of the measures required to address these issues have been identified. Neuroanatomy is perceived as a more difficult subject compared to other anatomy topics (e.g., reproductive/pelvic anatomy) and not all components of the neuroanatomy curriculum are viewed as equally challenging. The difficulty in understanding neuroanatomical concepts is linked to intrinsic factors such as the inherent complex nature of the topic rather than outside influences (e.g., lecture duration). Participants reporting high levels of interest in the subject reported higher levels of knowledge, suggesting that teaching tools aimed at increasing interest, such as case‐based scenarios, could facilitate acquisition of knowledge. Newer pedagogies, including web‐resources and computer assisted learning (CAL) are considered important tools to improve neuroanatomy learning, whereas traditional tools such as lecture slides and notes were considered less important. In conclusion, it is suggested that understanding of neuroanatomy could be enhanced and neurophobia be decreased by purposefully designed CAL resources. This data could help curricular designers to refocus attention and guide educators to develop improved neuroanatomy web‐resources in future.
