Consensus among stakeholders about success factors and indicators for quality of online and blended learning in adult education: a Delphi study

Quality models for online and blended learning (OBL) have mainly been developed in higher education. The literature indicates that these models are often conceptualised from the providers’ perspective. What is important for the quality of OBL from the students’ perspective has recently received increased attention in the literature. Consensus among stakeholders about students’ quality needs is useful to support dialogue between professionals to strategically adopt OBL and to ensure that the needs of students are met. This study aims to validate a quality instrument for OBL, taking a set of 74 quality indicators and analysing them in terms of seven success factors (credibility, accessibility, transparency, flexibility, interactivity, personalisation, productivity). The Delphi method was selected as most suited. Participants from adult education were asked to indicate on a 7-point Likert scale to what extent the indicators add to OBL quality to meet students’ needs. After four Delphi rounds, the participants agreed on definitions of success factors and 30 indicators. The results are useful for institutions, ministries of education and external quality assessment agencies to assess the quality of OBL and can support institutions to implement improvement actions to ensure that the needs of students are met.  相似文献

Pedagogical practices of NetNZ teachers for supporting online distance learners     

Kwok-Wing Lai 《Distance Education》2017,38(3):321-335

A supportive online learning environment entails teachers using effective pedagogical practices to meet the needs of their students and developing a positive teacher–student relationship to foster learner motivation and engagement. This paper reports a study investigating how 32 secondary teachers in New Zealand taught their online distance classes and how they related to their students. These classes were administered by NetNZ, an online distance education community. An online survey conducted in 2016 found that NetNZ teachers used inquiry-based practices including flipped learning and knowledge-building pedagogies to support agency, autonomy, collaboration, and community development. They also used synchronous and asynchronous communication technologies to overcome barriers of relationship building in online settings. NetNZ was unique in delivering distance education in the New Zealand context in that it used a community approach to encourage a more active participation of its member schools and teachers in delivering distance courses to secondary students.  相似文献   

Deliberative communication goes to college: the ‘Deliberation Forum’ project as a democratic agent of empowerment for communication students     

Vered Malka 《Learning, Media and Technology》2016,41(4):546-565

A new field of research has developed over the last few decades, called ‘Deliberative Communication’. It focuses on the potential contribution of public deliberations to strengthening the foundations of democracy and the promotion of social–political goals and objectives. The current research focuses on a unique case study, the ‘Deliberation Forum’ project, conducted by the Department of Communication at the Yezreel Valley College, Israel. The researcher sought to learn about students' experience of participating in this online forum and the effects they attributed to it, through unstructured interviews she held with them. The students indicated that, for the most part, the experience of participating in the deliberation forum was very positive: it enhanced their self-image as thinking people; strengthened their sense of self-importance as students within the department; developed and reinforced habits of keeping abreast of current affairs as well as critical thinking; and finally, the experience developed and strengthened habits of active participation in pluralistic debates. The study findings indicate that participation in projects of this kind has a clear empowerment potential, while also improving participants' attitude toward public deliberation and decision-making processes.  相似文献   

‘You want us to teach outdoor education where?’ Reflections on teaching outdoor education online     

H. A. Smith  J. E. Dyment  A. Hill  J. Downing 《Journal of Adventure Education & Outdoor Learning》2016,16(4):303-317

This article reports on the experiences of two lecturers working at the University of Tasmania required to teach outdoor and sustainability education (O&SE) courses online. Using an (auto)ethonographic case-study approach, the lecturers were interviewed with a view to exploring their perceptions, challenges, ethical dilemmas, tensions, opportunities and experiences in this space. A number of themes emerged, including commitment to quality teaching and learning, the role of experience, and experiential learning, in the online space, the challenge of fostering a connection to place, difficulties faced when trying to develop a learning community, and the role of professional learning and support in terms of pedagogy and technology in the online space. These themes, and their implications for teaching and learning in higher education both generally, and specifically in O&SE, are discussed in light of what is a mounting body of literature exploring the move to online delivery in higher education.  相似文献
