One of the challenges facing education systems in general and the South African education system in particular is how to understand ways that teachers change from nonusers of technologies to becoming transformative teachers with technology. Despite numerous initiatives, not limited to training, workshops and so forth, to bring about sustained and wide-spread teacher change, transmission/delivery-based pedagogies and chalk-and-talk methods continue to dominate. While policy directives and professional development programmes aim to effect change in teachers' practice, they tend to fail to create sustainable change in teachers' practice of using emerging technologies (ETs). This paper reports on a study that sought to understand how teachers change their pedagogy of teaching with ETs. Using a Design-Based Research approach, the paper reports on the teachers' pedagogical change framework (Teaching Change Frame-TCF) as a diagnostic tool for locating and mapping how teachers' change. The TCF maps teachers' existing pedagogies and ET uses, and designs a pathway of a change process to effect the desired change. The TCF was tested and refined using data from 325 teachers drawn from rural, resource-constrained schools, urban, well-resourced schools and from preservice teaching students in a decontextualized environment. Following three iterations it was found that teachers' use of ETs in regulated, restrictive ways correlate with transmission pedagogies, unregulated, dispersed ways correlate with transformative pedagogies. The use of TCF not only located teaching pedagogies but also provide different pathways to ensure sustainable change. Findings emphasize the need for teachers to encourage learners to build/create/construct with ETs and for increased interaction in fostering nonregulated dispersed use of ETs.

Although social networking sites (SNS) are increasingly popular among students, their academic application is unfolding on trial basis and best practices for integration into mainstream teaching are yet to be fully realised. More importantly, is the need to understand how these sites shape academic relations and participation of heterogeneous students, particularly in resource-constrained African environments. The speculation about meaningful educational uses of SNS possibly rests on the complexity of grasping the multiple horizontal and vertical interactions that unfold via these sites. This study examines academic relations on Facebook with a view to generating a nuanced account of how power is reinforced or disrupted in interactions mediated by Facebook. The paper analyses the Facebook wall and forum postings of 165 first year Information Systems students and employs Anderson's model of six types of interactions to explore student experiences of the enactments of social power in Facebook engagements. Issues relating to power that emerged from Facebook interactions concerned asymmetrical engagements based on gender, breaching of hierarchical boundaries, compulsive academic use of Facebook, perceptions of vertical surveillance, lecturer and student projection of themselves and impression management. The paper recommends that learning with and from Facebook demands identification of leverage points in various stages of Facebook interaction.

In the last decade, emerging technologies and transformative practices have diffused into higher education social systems in ways that formal leadership styles are increasingly stretched to both keep abreast of and to manage. While many scholars have argued for the importance of the role of leadership styles in shaping the strategic direction of institutions, there is a paucity of research on the role that informal leaders, and more particularly opinion leaders and change agents, can play in enabling wide-scale adoption of innovations in higher education institutions. This paper focuses on the ways in which leadership in higher education can best extend their influence to accelerate the diffusion of transformational educational practices using emerging technologies by leveraging informal leaders. To illustrate how this could be achieved, we report on a study of 22 public higher education institutions in South Africa involving 259 participants who responded to an online survey. The survey focused on the uses of emerging technologies to transform the teaching and learning practices and the nature of institutional support such initiatives received. The findings reveal that for emerging technologies to be diffused in institutional social systems, more transformative and less transactional leadership is required. The paper proposes a model for accelerating the diffusion of emerging technologies in higher education institutions and concludes that leveraging informal leadership is particularly critical in accelerating the uptake of emerging technologies practices.

Although there is an increasing use of emerging technologies (ETs) in higher education internationally and in South Africa in particular, there is little evidence that their use is transforming teaching and learning practice. Anecdotal evidence shows that there is a dichotomy between the technologies supported and used in higher education institutions (HEIs) on one hand, and technologies owned and predominately in use among students. Thus, the gulf between technologies supported and used for teaching and the technologies used by students for learning has created pressure for educators to "play catch-up," resulting in a continuum of pedagogically ineffective to effective uses of ETs. This paper argues that pedagogically sound uses of ETs leverage the broader context of existing practices (cultural-historical context) to design learning activities that transform both the teaching and learning practices. The paper draws data from a national survey on uses of ETs among educators in higher education to propose a pedagogical model of use that has the potential to transform practice.

Although use of podcasts and vodcasts are increasingly becoming popular in higher education, their use is usually unidirectional and therefore replicates the transmission mode of traditional face-to-face lectures. In this paper, the authors propose a tool, MOBILect, a mobile lecturing tool that enables users to comment on lecture vodcasts using mobile devices, and aggregated comments become an educational resource. The vodcasts are generated through Opencast Matterhorn and YouTube. The tool was evaluated at the University of Cape Town with students' own devices. The paper reports on the architecture of the MOBILect, its framework for student-vodcast interaction, and evaluation results. The paper concludes that the MOBILect has potential for use as a supplement to the traditional face-to-face lectures especially in scenarios of large classes, or where the medium of instruction is not the students' mother tongue.

The paper employs two case studies to develop an approach for using podcasts to enhance student learning. The case studies involve two cohorts of postgraduate students enrolled on a blended course, over two years. In both cases, the institutional learning management system was used as a server to host the podcasts, giving students discretion on how and when to listen to podcasts. The podcasts were integrated in learning design hence tightly coupled in pedagogy in Case One, and optionally used i.e., loosely integrated in Case Two. Semi-structured in-depth interviews were employed to solicit student experiences of using podcasts. Access logs from the podcast server provided insight into frequency of use of podcasts, thereby helping to establish the relation between podcast use and facilitation of learning. The findings suggest that students were confident in using podcasts for academic purposes. This is despite having had to overcome some challenges not limited to institutional policies on limited Internet quota for students. The findings also suggest that use of podcasts within a constructivist learning environment afforded learners control and flexibility, reflection and self-paced learning. The paper concludes that podcasts facilitate learning when tightly coupled to a curriculum and used within constructivist learning environments. (Contains 4 tables and 2 figures.)

While supplementation of face-to-face (F2F) teaching with online engagement is increasingly common, the educators' challenge of teaching F2F personalities and facilitating online personalities has not been widely explored. In this paper, we report on a project in which 1st-year students attended F2F sessions and engaged with an anonymous online questioning environment. The differences between students' F2F and online behaviour led to intended and unintended consequences. The purpose of this paper is to explore these intended and unintended consequences of technology use. The project was undertaken over a 3-year period, starting in 2004. In 2004, a pilot project was conducted based on a class of 35 students studying a 1st-year programming course in information systems. The investigation was again conducted in 2005 for the same course, this time with 63 students. In 2006, the project was extended to a class of 610 1st-year commerce students studying an introductory information systems course. In all cases, students met F2F and when online, engaged with an anonymous Web/SMS collaborative tool. The intended consequence was that a blending of F2F with online interaction extended student engagement beyond the limitation of a classroom and provided a forum for further collaboration and consultation. The intended outcome was achieved. An unintended consequence was that the tool provided the lecturer with diagnostic information that was used to impact on pedagogical designs. This was often a result of students taking on an online personality that would very often be extremely frank and honest about the manner in which the course was conducted, and how learning was taking place. The findings show that students used the tool in ways that exceeded the envisaged intention, and student use of the tool positively impacted on the curriculum, pedagogy and general running of the course. The paper concludes that integration of online engagement with F2F teaching adds value to the teaching and learning experience.

South African Universities are tasked with increasing student throughput by offering additional academic support. A second task is to teach students to challenge and question. One way of attempting to achieve these tasks is by using Information and Communication Technology (ICT). The focus of this paper is to examine the effect of using an ICT tool to both increase academic support to students, and to teach critical thinking skills. A field study comparing a Project Management course at the University of Cape Town over two successive years was conducted. In the second year an ICT mediated constructivist approach (DFAQ web site) in which students acquired project management skills was used to increase support and teach critical thinking skills. Structuration theory, in particular the notion of practical and discursive consciousness, was used to inform our understanding of the role of questioning on teaching project management. The conclusion is that a constructive approach, mediated by an anonymous web-based consultative environment, the Dynamic Frequently Asked Questions (DFAQ) improved support to students and had an effect on student learning of project management and students acquired some questioning skills as evidenced in the examination performance. The efficacy of the approach was evaluated both through an interpretive study of DFAQ artefacts and the performance in the examination. The paper examines relevant literature, details the research objectives, describes a field survey, and the results. (Contains 1 table and 2 figures.)

This paper describes an evaluation of a web-based consultation space (a dynamic frequently asked questions environment--DFAQ) in which learners consult one another using questions, and in which both the flow of interaction and its artefacts become a resource available to a community of learners. The DFAQ is a special form of a Computer-Mediated-Communication tool specifically developed to facilitate question-based interaction. We argue that education is too complex a social structure to be evaluated using deterministic positivist quantitative approaches. Given the volatility of determining what constitutes value, costs, inputs and outputs and the complexity of dynamics of socialization, a non-deterministic qualitative approach, utilisation-focused evaluation approach is used. Our conclusion is that the DFAQ does contribute to students' academic performance and frees the lecturer-learner consultation time. (Contains 3 figures.)
