Perceptions of roles and responsibilities in online learning : a case study

The extensive introduction of online technologies to support teaching and learning is impacting how teachers teach and students learn. It is also affecting both teaching staff’s and students’ perceptions of what each others’ roles are. The research reported here is part of a larger study that explored different aspects of teaching and learning in online environments. This study was undertaken within an Australian university and involved an institution-wide survey of students. The paper reports on students’ perceptions of their roles as online learners and the expectations they have of online teachers. The outcomes of the research suggest that different cohorts of students have different expectations. These expectations are informed by their mode of study and also by their perceptions of how staff engage with online teaching. Recommendations include proactive management of student expectations by staff, as well as a commitment by staff to meet those expectations.

The learning outcomes of an online reflective journal in engineering

Reflective thinking based on experiential learning is a key skill required for the lifelong learner and the socially mature professional. Following several semesters employing a written reflective journal as an assessable task, a fourth-year engineering management unit adopted an online reflective journal. During the initial semester of use, an evaluation was undertaken to investigate student perceptions of the online journal. A summary of this previous work is presented here. Following three semesters of use of the online journal, an analysis of the student use of the journal was undertaken to investigate its contribution to unit learning outcomes. Based on the evaluation of student perceptions of the online reflective journal, it was found that a majority of students understood the purpose of the journal, and valued the journal in their learning; a majority of students read the journal entries of other students, and indicated that this assisted their learning; and the two most frequently reported ‘most useful’ aspects of the journal were the ‘enforced’ continuous revision of course material, and the ability to compare their understanding of the course material with that of other students. Based on a regression analysis of the factors related to student usage of the online reflective journal, it was found that the significant contributors to final unit mark where: prior academic performance; number of journal postings; and mode of study. This research confirmed that the online reflective journal was fertile territory in the landscape of educational technology, both in terms of student perceptions and contribution to unit learning outcomes.

Blended and online learning : student perceptions and performance

Purpose – The purpose of this paper is to improve educator knowledge of the antecedents and consequences of blended learning in higher education.

Design/methodology/approach – A longitudinal case study approach is adopted. Three case studies each involve tracking a student evaluations of teaching (SET) measure (willingness to recommend) and grade point average for three subjects from the same business discipline over six years. The cases involve comparison of: a business subject taught solely online; a business subject where experimentation in the blend of face-to-face teaching and learning is involved; and a business subject where face-to-face teaching is primarily used, and where in the most recent iteration online content supplements the learners' experiences.

Findings – The findings suggest that there are situations where integrated use of blended learning involving face-to-face teaching, digital media and digital communication with simple navigation between the content items leads to positive student perceptions. This is in contrast to negative student perceptions in the situation where learners must navigate in online learning, and where there is little or no face-to-face instruction. While not examined in detail, nor part of the research question, it is not surprising to find no relationship between learning mode and grade point averages is evidenced.

Research limitations/implications – The effects of prior computer literacy and language proficiency across the students used in this study, and potential demographic and experiential differences between on-campus and off-campus students are not controlled for. Additionally, only three business subjects are investigated and it is recognised that there is a need for a broader study. Finally, with response levels to the university-controlled SET that typically range between 20-43 per cent for these large subjects, there is possible non-response bias that it was not possible to counter over the six years involved.

Practical implications – The findings in this study suggest that while blended learning offers many benefits to higher education institutions and learners alike, care needs to be taken in the manner in which such approaches are implemented in light of possible negative learner perceptions where a less traditional approach is taken.

Originality/value – A major contribution of this study is the fact that experimentation has taken place in terms of the degree of face-to-face and online learning that have been blended in at least one subject (case study two), and the fact that the SET for this subject are compared, longitudinally, with two other subjects which lie on either side of this subject in terms of the extent of online and face-to-face teaching and learning employed – 100 per cent online in case study one and almost 100 per cent face-to-face in case study three.

Online learning environments : same place; different demographic space?

This paper presents a large scale, quantitative investigation of the impact of demographic differences on the student experience of using an online learning environment (OLE). Female respondents generally gave higher ratings than males, and gave significantly higher ratings in both importance and satisfaction to a group of OLE elements related to online interaction and community. Postgraduate respondents generally gave lower satisfaction ratings than undergraduate students, though significant differences were few. Results on the basis of mode of enrolment were mixed. The discovery of significant differences between demographic groups highlights the importance of up-to-date and on-going research-based surveys of student perceptions of the OLE. The finding that elements of the institutional OLE are not universally perceived the same way by all students groups also challenges the value of standard, one-size-fits-all institutional policies and templates relating to the use of the OLE.

Quality in flexible, online and distance education at Deakin University, Australia

This chapter presents an overview of the management of quality for flexible, online and distance education (off-campus education) at Deakin University in Australia. In 1974, Deakin University was established as a dual-mode institution educating large numbers of both on- and off-campus students. From its foundation it has increasingly sought to provide the same learning resources, equivalent learning experiences and parity of outcomes to students studying in all modes (Hay, Lowe, Gibb & Anderson, 2002). While this was the ideal on which Deakin was founded, in practice approaches differed across various schools and courses where in some areas integration was achieved through an open-campus model, while in others the tendency was towards separation of the modes of delivery by course. Deakin’s history can be characterised as moving from dual-mode approaches to educating its student cohorts, to a now well articulated, integrated and institution-wide approach to assuring and improving the quality of all modes of educational delivery for an extremely diverse and complex set of student cohorts. In this regard, it makes no particular distinction between these student groups in its policies, procedures and processes relating to educational matters.

• the total number of follow-up/reply discussion postings made by the student; and
• the final unit mark obtained by the student.

Understanding the context of distance students : differences in on- and off-campus engagement with an online learning environment

 While a growing number of higher education institutions are providing online modes of study for both on- and off-campus students, there are very real differences in demography, technology experiences, reasons for study, etc. between on- and off-campus students, and research into engagement with online learning environments (OLEs) indicate differences in the way that on- and off-campus students interact with OLEs. In Australia, Deakin University is a major provider of distance and online education, and provides a case study of a higher education institution with a mature and large-scale OLE implementation providing support to both on- and off-campus students. Deakin Studies Online (DSO) is Deakin University’s OLE. Based on a representative sample of 1322 responses to the 2011 DSO evaluation survey, this paper presents a large-scale, up-to-date and fine-grained investigation of impact of mode of study on the student experience of using an OLE. It was found that the primary place of access to DSO for both groups was home, mobile access to DSO seems likely to be of growing importance to both groups, and there was no statistically significant difference in the mean satisfaction ratings between on- and off-campus students for virtually all DSO functions. Off-campus students gave significantly higher mean ratings of importance (though not satisfaction) to a range of DSO functions that could be viewed as ‘value adders’ by off-campus students, enhancing their overall learning experience. For more than half of the DSO functions surveyed, on-campus students reported statistically significant higher mean frequency of access than off-campus students. The finding that elements of the institutional OLE are not universally perceived and used the same way by all students groups challenges the value of standard, one-size-fits-all institutional policies and templates relating to the use of OLEs.

What was web 2.0? Versions as the dominant mode of internet history

This paper explores Web 2.0 as the marker of a discourse about the nature and purpose of the internet in the recent past. It focuses on how Web 2.0 introduced to our thinking about the internet a discourse of versions. Such a discourse enables the telling of a ‘history’ of the internet which involves a complex interweaving of past, present and future, as represented by the additional versions which the introduction of Web 2.0 enabled. The paper concludes that the discourse of versions embodied in Web 2.0 obscures as much as it reveals, and suggests a new project based on investigations of the everyday memories of the internet by which individual users create their own histories of online technology.

Online blind source separation using incremental nonnegative matrix factorization with volume constraint

Online blind source separation (BSS) is proposed to overcome the high computational cost problem, which limits the practical applications of traditional batch BSS algorithms. However, the existing online BSS methods are mainly used to separate independent or uncorrelated sources. Recently, nonnegative matrix factorization (NMF) shows great potential to separate the correlative sources, where some constraints are often imposed to overcome the non-uniqueness of the factorization. In this paper, an incremental NMF with volume constraint is derived and utilized for solving online BSS. The volume constraint to the mixing matrix enhances the identifiability of the sources, while the incremental learning mode reduces the computational cost. The proposed method takes advantage of the natural gradient based multiplication updating rule, and it performs especially well in the recovery of dependent sources. Simulations in BSS for dual-energy X-ray images, online encrypted speech signals, and high correlative face images show the validity of the proposed method.

Gatecrashing the research paradigm : effective integration of online technologies in maximising research impact and engagement in legal education

Legal academics are not only teachers but also creators of knowledge. The role of an academic includes a responsibility to share this knowledge through engagement not just of their students, but also of the wider community. In addition, there is increasing emphasis on legal academics having to account for the so-called ‘impact’ of research. In selecting both the topic of their research and the mode of publication of their knowledge, legal academics act as gatekeepers. There is an increasing critique of the existing paradigm of research publication and its emphasis on the metrics of impact. This critique recognises the limitations of the commercial publication paradigm in the present context of open access and the vast array of citizen-mediated platforms for dissemination of legal knowledge and innovation. Susskind (Tomorrow’s Lawyers 2013) for example identifies expert crowd-sourced legal information as breaking down barriers to access to justice. Tracking their experience with publication of a paper on social media in legal education from the ALTA conference in 2012, the authors share an auto-ethnographic account of their insights into the potential for both impact and engagement of a diverse audience in their research. This highlights the ways in which various media can be used strategically to redefine the role of the gatekeeper.

Prestimulus default mode activity influences depth of processing and recognition in an emotional memory task

Low self-referential thoughts are associated with better concentration, which leads to deeper encoding and increases learning and subsequent retrieval. There is evidence that being engaged in externally rather than internally focused tasks is related to low neural activity in the default mode network (DMN) promoting open mind and the deep elaboration of new information. Thus, reduced DMN activity should lead to enhanced concentration, comprehensive stimulus evaluation including emotional categorization, deeper stimulus processing, and better long-term retention over one whole week. In this fMRI study, we investigated brain activation preceding and during incidental encoding of emotional pictures and on subsequent recognition performance. During fMRI, 24 subjects were exposed to 80 pictures of different emotional valence and subsequently asked to complete an online recognition task one week later. Results indicate that neural activity within the medial temporal lobes during encoding predicts subsequent memory performance. Moreover, a low activity of the default mode network preceding incidental encoding leads to slightly better recognition performance independent of the emotional perception of a picture. The findings indicate that the suppression of internally-oriented thoughts leads to a more comprehensive and thorough evaluation of a stimulus and its emotional valence. Reduced activation of the DMN prior to stimulus onset is associated with deeper encoding and enhanced consolidation and retrieval performance even one week later. Even small prestimulus lapses of attention influence consolidation and subsequent recognition performance. Hum Brain Mapp, 2015. © 2015 Wiley Periodicals, Inc.
