Comparing face-to-face and asynchronous online communication as mechanisms for critical reflective dialogue     

Susan Salter  Tracy Douglas  David Kember 《Educational Action Research》2017,25(5):790-805

Two mechanisms for engaging in critical reflective dialogue are discussed and compared: face-to-face meetings and asynchronous online discussion. The context is an umbrella action research project, with over 20 participants, which aimed to improve practices in online teaching and contribute to the development of graduate attributes. The article compares discussion using the two modes (face-to-face and online) of the nature of and development of problem-solving and other graduate attributes. Face-to-face discussion was wide ranging and quite loosely structured, so divergent aspects of a topic were uncovered. The asynchronous nature of online discussion, however, permitted topics to be explored more thoroughly. The two modes worked well in conjunction with one another, if aspects of face-to-face discussion topics were posted online as discussion threads. The asynchronous online discussions then allowed each thread to be explored in depth, so that collective understanding of a given topic could be enhanced.  相似文献

Integrating Computer-Mediated Communication into an EAP course     

Xiao Li  Ru-hua Cao 《Frontiers of Education in China》2006,1(4):589-600

The development of the computer along with the widespread use of the Internet has rapidly promoted Computer-Mediated Communication (CMC) as a very important communication media, which can be used widely and effectively in foreign language teaching and learning. This essay tries to explore the advantages of CMC as well as its proposed application, beginning with the introduction of some concepts related to CMC. From the research history, the rationale of using CMC in foreign language learning is summarised. The context of an EAP course is introduced and some suggestions on using CMC in this course are proposed.  相似文献

A novel high power-density PMSM (permanent magnetic synchronous motor) with independent magnetic flux path for each phase is proposed in the paper.The complex mathematic model of PMSM is simplified by decoupling of magnetic flux paths between motor phases.In addition,harmonic compoments are lowered through optimum design of EMF (electric motive force) wave.Thus the ripple torque caused by EMF wave distortion is suppressed.  相似文献   

A Meta-Analysis of Approaches to Engage Social Work Students Online     

Dorothy Farrel  Kateri Ray  Telvis Rich  Zulema Suarez  Brian Christenson  Lisa Jennigs 《Journal of Teaching in Social Work》2018,38(2):183-197

ABSTRACT

With an increase in social work courses being offered in online and hybrid formats, it is imperative that social work programs understand the new teaching tenets and engagement mediums employed to meet the new Council on Social Work Education’s Educational Policy and Accreditation Standards. This meta-analysis explores best-practices pedagogy for student engagement using the delivery of content through both asynchronous and synchronous methods.  相似文献   

Teacher Perceptions of Moodle and Throughput in a Blended Learning Programme for In-Service Secondary School Mathematics Teachers     

Mdutshekelwa C. Ndlovu  Ingrid Mostert 《Africa Education Review》2018,15(2):131-151

The purpose of this article is to analyse teachers’ perceptions of using the modular object-oriented dynamic learning environment (Moodle) platform as a learning management system in a small-scale blended learning (b-learning) Advanced Certificate in Education (ACE) programme for in-service secondary school mathematics teachers in South Africa. It describes how the Moodle platform was used in combination with on-campus and later off-campus contact sessions for a widely dispersed population of 76 in-service mathematics teachers over a four-year period. Qualitative data was gathered by means of a questionnaire with open-ended items, while quantitative data was gathered from the centre's archives. The main findings were that Moodle enabled in-service teachers to experience social, cognitive and teaching presences, through synchronous and asynchronous discussions with peers and facilitators, and a teaching presence by submitting their inquiries and assignments online for facilitators to provide them with answers and feedback. The main obstacles to the integration of Moodle were limited availability of technology, slow speed, and unaffordable cost when available. With increased broadband connectivity Moodle holds the prospect for diversifying b-learning experiences that can support teachers’ professional learning outcomes and throughput for distributed populations of practising mathematics teachers, in particular.  相似文献
