ItemPedagogical and cognitive usability in online learning( 2013)The last decade has seen a sharp – and necessary – increase in attention to the quality of eLearning which has expanded a relatively new area of usability specifically for online learning: pedagogical usability. This research focuses on the usability attributes that contribute to effective eLearning and delineates those pertinent to teaching (pedagogical usability) and those specific to learning (cognitive usability). A multifarious methodology provided the elicitation of data from almost all conceivable and feasible angles of the execution of eLearning in a real-world setting – the main positions being: the pedagogical considerations from the teacher-developers’ planning sessions through to the use of a Virtual Learning Environment (VLE) by students, as well as an in-depth usability inspection and evaluation of the Learning Management System (LMS) used as the tool for delivery. The project, in essence, put a microscope on the entire process of eLearning. The complementary use of twelve methods of data collection for rigorous triangulation provided a synergic framework that enabled the examination of each stage of eLearning. The analytical framework applied to the data comprised a complex integration of existing models and a specifically devised analytical model that assisted in the deconstruction of all the factors that contribute to pedagogical and cognitive usability. The study introduces the concept of cognitive usability as distinct from pedagogical usability on the grounds that certain features and contributing factors to VLEs are more teacher-driven (pedagogical) while others are more learner-consummated (cognitive). The study found that a VLE’s constitutional design is governed by teachers’ philosophies about teaching and learning and their teaching styles and repertoires which in turn are also governed by curriculum design; the teachers’ lack of techno-pedagogical skills coupled with the limitations of the eLearning platform hold an equally pivotal role in determining the VLE’s pedagogical usability. The study showed a strong relationship between the technical, pedagogical and cognitive usability of a VLE and found that using an LMS to create eLearning is fraught with problems that are rooted in the technical design of the LMS. Since LMSs are a mandatory feature in almost all educational institutions nowadays, the findings of this study are particularly important since so much research focuses on the use of eLearning without specifically addressing the software used to create it. While even a VLE with low techno-pedagogical usability can still facilitate learning outcomes, this study showed that approximately one third of VLE activity is ineffective due to poor LMS design which impacts on the VLE design, leading to low cognitive usability.

ItemPrimary teachers and the Information and Communications Technology domain: figuring worlds, identities, knowledge and practices( 2010)This study investigates the development of teacher professional practice in the context of government education policy in Victoria (Australia) that aims, through the education of its youth, to shape a successful economy that capitalises on information and communications technology (ICT). Specifically, the study examines how selected primary teachers from an ICT network conceptualise, articulate and develop a body of knowledge to teach and implement the Information and Communications Technology domain of the Victorian Essential Learning Standards (Victorian Government, 2005) curriculum framework. Through a constructivist grounded theory approach, the study investigates the practices of six female teachers in three government primary schools as they implement changes to curriculum in response to government reforms and local expectations. The three primary schools are within close proximity of each other in a residential growth corridor on the fringes of metropolitan Melbourne, and serve a diverse and multicultural community. Innovation with ICT is seen as necessary for addressing the challenges that arise from the social and economic context of the research sites, and is integral to improvement plans in each of these schools. The participating teachers are regarded as leaders with ICT within their schools and their efforts are deemed intrinsic to their school’s plan. Rich descriptive data of these six teachers and how they construct their worlds is utilised to develop a theory of how teachers learn to teach with ICT, with a view to understanding how they continue to learn in the context of these changes. Change efforts often focus on the importance of knowledge building to empower professionals for new directions, however while a critical component, knowledge is not the only factor in increasing capability. The study highlights that learning to teach the ICT domain is more complex than developing content knowledge, pedagogical repertoire and skills in the use of ICT. It involves networked learning where values, beliefs, vision, practice and identities are made and remade. In making changes, teachers consider new ideas in light of the old, and through the lens of their core values and beliefs, they figure a technologically rich world of vast imaginings that they can embody. They author identities to assert themselves in relation to imposed positioning and prior conceptualisations. Through changed activity related to ICT, they redefine their conception of teaching and inhabit it with their activity and energy.
