Web 2.0 for networked learning : from collaboration to shared cognition and knowledge networking

This poster presents research-in-progress into the educational affordances of so-called Web 2.0 sites, services, with a particular emphasis on those applications that involve forms of shared human-machine cognition and that promote public knowledge networking. This research involves reviewing many hundreds of Web 2.0 tools and selecting approximately 50 for further analysis and exploration as learning applications. In doing so, the research will generate examples of unusual affordances provided by Web 2.0; it will also present a more structured categorisation of the kinds of uses and benefits of these tools. This approach is valuable because much current research and analysis of the impact of Web 2.0 on education, particularly higher education, has emphasised a relatively limited array of tools – principally blogs, wikis and social networking services – that offer educators and students opportunities for student-led collaborative work. Such opportunities involve strong emphasis on constructivist pedagogy: students’ interactions with each other, mediated via the Internet, are viewed as the positive benefit which networked learning can provide. However, Web 2.0 is far more than just collaboration, and associated shared self-expression. In particular, Web 2.0 includes many examples of services that take one form of input from a user and, rather than just sharing it with others, enable the transformation of that input into different forms, either as visualisations, maps, or other re-representations. Web 2.0 is also starting to see the development of knowledge-work engines that embody the concept of shared cognition, in which the service and the user cooperate in the production of some final knowledge output or which present to users knowledge that has already been processed more extensively than through simple searching. Web 2.0 is also closely associated with the idea that knowledge work is now networked and distributed; it involves users appropriating, creating and sharing knowledge products in a very public way, far beyond the narrow ‘audience’ of a particular course or program of study. The research presented in this poster will provide, firstly, examples of the Web 2.0 tools which emphasise these additional ways of exploiting the Internet for networked learning; secondly, the research will provide a first iteration of the overarching structure of categories and classifications which can be used to assess any proposed Web 2.0 application in terms of its affordances for learning as knowledge networking. By understanding these technologies, truly collaborative networked learning can be developed that blends with the emerging cultures of online behaviour increasingly common to contemporary student populations.

A critical pedagogy of embodied education : learning to become an activist

Unlike any current publication on social purpose education, this book explores the differences and similarities between two groups of activists: lifelong activists who have been engaged in campaigns and socials movements over many years and circumstantial activists, those protestors who come to activism due to a series of life circumstances. Using empirical research conducted in Australia, Tracey Ollis outlines the pedagogy of activism and the process of learning to become an activist.

The efficient imputation method for neighborhood-based collaborative filtering

As each user tends to rate a small proportion of available items, the resulted Data Sparsity issue brings significant challenges to the research of recommender systems. This issue becomes even more severe for neighborhood-based collaborative filtering methods, as there are even lower numbers of ratings available in the neighborhood of the query item. In this paper, we aim to address the Data Sparsity issue in the context of the neighborhood-based collaborative filtering. Given the (user, item) query, a set of key ratings are identified, and an auto-adaptive imputation method is proposed to fill the missing values in the set of key ratings. The proposed method can be used with any similarity metrics, such as the Pearson Correlation Coefficient and Cosine-based similarity, and it is theoretically guaranteed to outperform the neighborhood-based collaborative filtering approaches. Results from experiments prove that the proposed method could significantly improve the accuracy of recommendations for neighborhood-based Collaborative Filtering algorithms. © 2012 ACM.

The politics of coastal policy, planning and governance in Canada and Australia : business as usual, at a distance, or collaborative?

Canada and Australia are countries with substantial coastal zones which provide significant economic, social and environmental benefits and opportunities. The coastal zones of Canada and Australia also share significant threats such as, pollution, loss of biodiversity, and climate change, while also facing different challenges that are unique to their particular contexts. Effective management of such zones therefore represents a considerable challenge because of the: complexity of biophysical processes; multiple threats faced; uncertainties associated with understandings of such processes and threats, and the multiple jurisdictions and stakeholder viewpoints as to how such environments should be managed. Further, coasts and the sustainability of coastal resources and ecosystems have been argued to represent ‘wicked problems’ such that their governability is called into question. Therefore drawing on recent experiences in coastal policy, planning and governance in Newfoundland, Canada, and Victoria, Australia, this paper assesses the adequacy of current approaches to coastal governance in the two jurisdictions. In doing so we draw on recent policy and governance literature to consider whether coastal policy, planning and governance in Newfoundland and Victoria, reflect a collaborative, neoliberal, or business as usual (ad hoc, top down) approach. Based on such an assessment we consider the prospects for more integrated coastal zone management in each jurisdiction, as well as broader implications for governance and the resilience of coastal systems. It is argued that while both jurisdictions would benefit from a more collaborative approach, the mechanisms for bringing about such an approach would vary and will not come easily in light of institutional and historic barriers.

Characterising secondary school teacher imperatives as subject (signature) pedagogies : a pedagogy of support in maths and a pedagogy of engagement in science

The ideas of Lee Shulman have played a major role in reconceptualising pedagogical description. In 2005, Shulman described a construct called “signature pedagogies” in order to describe recognisable and distinctive pedagogies used to prepare future practitioners for their profession. As a broader application of Shulman’s ideas, this paper asks, what is the efficacy of describing pedagogies that have become entrenched in secondary school subjects as signature pedagogies? Approached from a cultural perspective these questions are examined by comparing the subject cultures of junior school maths and science as experienced by, and represented in the classrooms of, a small number of teachers from two secondary schools in Victoria, Australia. In this research, subject culture is underpinned by shared basic assumptions that govern the dominance of certain “subject paradigms” (what should be taught) and “subject pedagogies” (how this should be taught) (Ball & Lacey, 1980). In this secondary school setting, the term signature pedagogies can be equated to the term subject pedagogies on the basis that both aim to characterise practice across the subject, or discipline, based on what was perceived as central to the task of teaching and learning. The paper draws on classroom observation and teacher interview data to show how six teachers positioned two aspects of their teaching in relation to what they believed was central in shaping their maths and science teaching: the effect of the arrangement of curriculum content on teachers’ conceptualisations of the teaching task; and a pedagogical imperative to engage students through activity-based learning experiences. The cultural expectations surrounding these two aspects of teaching appear to have a strong influence on practice, and in some senses teachers’ pedagogical responses were clear. These common responses are what I am calling “subject pedagogies” (see Ball & Lacey, 1980) because there was general agreement about what was central to the teaching task. Two subject pedagogies were seen to represent strong discourses occurring in both subjects: a “Pedagogy of Support” in maths, and “Pedagogy of Engagement” in science. Their established and shared character resembled Shulman’s posited “signature pedagogies” (Shulman, 2005). The data shows that by evaluating cultural practices that teachers have in common, and assumptions underpinning these, there is potential for highlighting imbalances, strengths and weaknesses, and connections and disconnections, associated with prevailing subject pedagogies.

Science students' perceptions of engaging pedagogy

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old students and their teacher were monitored for the whole school year, employing participant observation, and interviews with focus groups of students, their teacher and other key members of the school. Analysis focused on how students perceived the role of the teacher's pedagogy in constructing a learning environment that they considered conducive to engagement with science learning. Two areas of the teacher's pedagogy are explored from the student perspective of how these affect their learning: instructional pedagogy and relational pedagogy. Instructional pedagogy captures the way the instructional dialogue developed by the teacher drew the students into the learning process and enabled them to “understand” science. How the teacher developed a relationship with the students is captured as relational pedagogy, where students said that they learned better when teachers were passionate in their approach to teaching, provided a supportive learning environment and made them feel comfortable. The ways in which the findings support the direction for the middle years and science education are considered.
