Integrating organizational, social, and individual perspectives in Web 2.0-based workplace e-learning

From the issue entitled 'Special Issue: Emerging Social and Legal Aspect'E-learning is emerging as a popular approach of education in the workplace by virtue of its flexibility to access, just-in-time delivery, and cost-effectiveness. To improve social interaction and knowledge sharing in e-learning, Web 2.0 is increasingly utilized and integrated with e-learning applications. However, existing social learning systems fail to align learning with organizational goals and individual needs in a systemic way. The dominance of technology-oriented approaches makes elearning applications less goal-effective and poor in quality and design. To solve the problem, we address the requirement of integrating organizational, social, and individual perspectives in the development of Web 2.0 elearning systems. To fulfill the requirement, a key performance indicator (KPI)-oriented approach is presented in this study. By integrating a KPI model with Web 2.0 technologies, our approach is able to: 1) set up organizational goals and link the goals with expertise required for individuals; 2) build a knowledge network by linking learning resources to a set of competences to be developed and a group of people who learn and contribute to the knowledge network through knowledge creation, sharing, and peer evaluation; and 3) improve social networking and knowledge sharing by identifying each individual's work context, expertise, learning need, performance, and contribution. The mechanism of the approach is explored and elaborated with conceptual frameworks and implementation technologies. A prototype system for Web 2.0 e-learning has been developed to demonstrate the effectiveness of the approach. © Springer Science + Business Media, LLC 2009.postprin

Professional Learning Communities as drivers of educational change: the case of Learning Rounds

Many researchers claim that there is a compelling weight of evidence for the effectiveness of PLCs in promoting teachers’ learning and pupil achievement. However, others raise fundamental questions about their nature and purpose. Some of the uncertainties about the nature and purpose of PLCs relate to the ways in which the macro-context of neo-liberalism has shaped the practices of PLCs in particular ways. The fundamental questions raised about PLCs relate to the type of change they are intended to produce, the model of community they are based on and whether the right conditions and skills are in place for them to contribute to change. Some researchers argue that we need to pay more attention to shortcomings within existing PLCs and their internal dynamics. Others argue that little research focuses on the specific interactions of teachers inside PLCs. The research reported here goes ‘inside the teacher community’ of Learning Rounds to explore what the shortcomings of some examples of this model in practice add to what we know about how to assist PLCs to produce change in education

<i>Trypanosoma ambystomae</i> in <i>Ambystoma</i> spp. (order Caudata) in southern Ontario

Using the haematocrit centrifuge technique, Trypanosoma ambystomae was recorded from Ambystoma jeffersonianum, Ambystoma platineum, Ambystoma laterale, Ambystoma maculatum, and Ambystoma tremblayi from five areas in southern Ontario. The percentage of infected animals varied from about 5% in A. tremblayi to 27% in A. platineum and A. maculatum. This report not only expands the host range for the trypanosome, it is also the first report of it being found outside western North America. The division process of the trypanosome in the salamander is described and it is shown that it can be maintained in salamanders in the laboratory by blood inoculation. </jats:p
