Managing evolution and change in web-based teaching and learning environments
The state of the art in information technology and educational technologies is evolving constantly.
Courses taught are subject to constant change from organisational and subject-specific reasons. Evolution
and change affect educators and developers of computer-based teaching and learning environments alike –
both often being unprepared to respond effectively. A large number of educational systems are designed
and developed without change and evolution in mind. We will present our approach to the design and
maintenance of these systems in rapidly evolving environments and illustrate the consequences of evolution
and change for these systems and for the educators and developers responsible for their implementation and
deployment. We discuss various factors of change, illustrated by a Web-based virtual course, with the
objective of raising an awareness of this issue of evolution and change in computer-supported teaching and
learning environments. This discussion leads towards the establishment of a development and management
framework for teaching and learning systems
A gentle transition from Java programming to Web Services using XML-RPC
Exposing students to leading edge vocational areas of relevance such as Web Services can be difficult. We show a lightweight approach by embedding a key component of Web Services within a Level 3 BSc module in Distributed Computing. We present a ready to use collection of lecture slides and student activities based on XML-RPC. In
addition we show that this material addresses the central topics in the context of web services as identified by Draganova (2003)
Semantic discovery and reuse of business process patterns
Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
Teaching and learning in virtual worlds: is it worth the effort?
Educators have been quick to spot the enormous potential afforded by virtual worlds for situated and authentic learning, practising tasks with potentially serious consequences in the real world and for bringing geographically dispersed faculty and students together in the same space (Gee, 2007; Johnson and Levine, 2008). Though this potential has largely been realised, it generally isn’t without cost in terms of lack of institutional buy-in, steep learning curves for all participants, and lack of a sound theoretical framework to
support learning activities (Campbell, 2009; Cheal, 2007; Kluge & Riley, 2008). This symposium will explore the affordances and issues associated with teaching and learning in virtual worlds, all the time considering the
question: is it worth the effort
Transforming pre-service teacher curriculum: observation through a TPACK lens
This paper will discuss an international online collaborative learning experience through the lens of the Technological Pedagogical Content Knowledge (TPACK) framework. The teacher knowledge required to effectively provide transformative learning experiences for 21st century learners in a digital world is complex, situated and changing. The discussion looks beyond the opportunity for knowledge development of content, pedagogy and technology as components of TPACK towards the interaction between those three components. Implications for practice are also discussed. In today’s technology infused classrooms it is within the realms of teacher educators, practising teaching and pre-service teachers explore and address effective practices using technology to enhance learning
Data mining technology for the evaluation of learning content interaction
Interactivity is central for the success of learning. In e-learning and other educational multimedia environments, the evaluation of interaction and behaviour is particularly crucial. Data mining – a non-intrusive, objective analysis technology – shall be proposed as the central evaluation technology for the analysis of the usage of computer-based educational environments and in particular of the interaction with educational content. Basic mining techniques are reviewed and their application in a Web-based third-level course environment is illustrated. Analytic models capturing interaction aspects from the application domain (learning) and the software infrastructure (interactive multimedia) are required for the meaningful interpretation of mining results

The potential of mobile phones to transform teacher professional development
Futures thinking is used by governments to consider long-term strategic approaches and develop policies and practices that are potentially resilient to future uncertainty. English in Action (EIA), arguably the world’s largest English language teacher professional development (TPD) project, used futures thinking to author possible, probable and preferable future scenarios to solve the project’s greatest technological challenge: how to deliver audio-visual TPD materials and hundreds of classroom audio resources to 75,000 teachers by 2017. Authoring future scenarios and engaging in possibility thinking (PT) provided us with a taxonomy of question-posing and question-responding that assisted the project team in being creative. This process informed the successful pilot testing of a mobile phone-based technology kit to deliver TPD resources within an open distance learning (ODL) platform. Taking the risk and having the foresight to trial mobile phones in remote rural areas with teachers and students led to unforeseen innovation. As a result EIA is currently using a mobile phone-based technology kit with 12,500 teachers to improve the English language proficiency of 700,000 students. As the project scales up in its third and final phase, we are using the new technology kit—known as the ‘trainer in your pocket’—to foster a ‘quiet revolution’ in the provision of teacher professional development at scale to an additional 67,500 teachers and 10 million students

Experimental and simulation study on the aerodynamic performance of a counter rotating vertical axis wind turbine
The Darrieus H-rotor has gained much interest in the last few decades as among the reliable devices for wind energy conversion techniques, for their relatively simple structure and aerodynamic performance. In the present work, development and aerodynamic performance predictions of a unique contra-rotating VAWT have been studied through experimental and computational approaches as it has yet to be applied to a VAWT. The main purpose of this study is to develop and investigate the practicality of employing the contra-rotating concept to a VAWT system while enhancing its conversion efficiency. The simulation study was performed using three-dimensional computational fluid dynamics (CFD) models based on K-omega shear stress transport (SST) model. The computational work covers a wider range of simulation processes compared to the experiment which includes a parametric study based on the axial distance between the two rotors and blade height. The performance evaluations of the current models were established in terms of key aerodynamic parameters such as torque and power. The systematic analysis of these quantities showed the usefulness of the contra-rotating technique on a VAWT system and the ability to extract additional more than threefold power over the entire operating wind speeds covered. The system has also improved the inherent difficulties of the Darrieus rotor to self-start. The results also demonstrated a significant increase in terms of conversion efficiency for both power and torque compared to a single-rotor system of a similar type. A maximum of 43% and 46% of power and torque coefficients were respectively possible with the current dual-rotor system. The simulation results indicate that smaller axial distance tends to enhance the performance output of the system relatively better compared to a larger distance. However, in terms of the blade height, longer blades generated the highest amount of power. It is anticipated that this current technique could revolutionize wind energy harvesting strategies and would find applications in a wide range of sites that are characterized by low and moderate wind regimes and particularly be useful in the urban environment where turbulence is high
