An ontology of agile aspect oriented software development

Both agile methods and aspect oriented programming (AOP) have emerged in recent years as new paradigms in software development. Both promise to free the process of building software systems from some of the constraints of more traditional approaches. As a software engineering approach on the one hand, and a software development tool on the other, there is the potential for them to be used in conjunction. However, thus far, there has been little interplay between the two. Nevertheless, there is some evidence that there may be untapped synergies that may be exploited, if the appropriate approach is taken to integrating AOP with agile methods. This paper takes an ontological approach to supporting this integration, proposing ontology enabled development based on an analysis of existing ontologies of aspect oriented programming, a proposed ontology of agile methods, and a derived ontology of agile aspect oriented development

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

Toward a Theory of Learner-Centered Training Design: An Integrative Framework of Active Learning

[Excerpt] The goal of this chapter, therefore, is to develop an integrative conceptual framework of active learning, and we do this by focusing on three primary issues. First, we define the active learning approach and contrast it to more traditional, passive instructional approaches. We argue that the active learning approach can be distinguished from not only more passive approaches to instruction but also other forms of experiential learning based on its use of formal training components to systematically influence trainees\u27 cognitive, motivational, and emotion self-regulatory processes. Second, we examine how specific training components can be used to influence each of these process domains. Through a review of prior research, we extract core training components that cut across different active learning interventions, map these components onto specific process domains, and consider the role of individual differences in shaping the effects of these components (aptitude-treatment interactions [ATIs]). A final issue examined in this chapter concerns the outcomes associated with the active learning approach. Despite its considerable versatility, the active learning approach is not the most efficient or effective means of responding to all training needs. Thus, we discuss the impact of the active learning approach on different types of learning outcomes in order to identify the situations under which it is likely to demonstrate the greatest utility. We conclude the chapter by highlighting research and practical implications of our integrated framework, and we outline an agenda for future research on active learning

Perceptual impact of environmental factors in sighted and visually impaired individuals

To a visually impaired individual the physical world presents many challenges. For a person with impaired sight, wayfinding through a complex environment is fraught with dangers, both actual and imagined. The current generation of mobility aids have the possibility of addressing a broad range of physical issues through technological solutions. The perception of difficulty however, can mean that many visually impaired individuals are fearful or uncomfortable about independent mobility or travel. In this context it becomes necessary to discover exactly what environments, environmental factors or items constitute a ‘perception of difficulty’ in the individuals mental landscape and may trigger a negative response before they interact with the physical environment. This paper reports on research, which sought to ascertain what levels of perceptual difficulties specific environments and factors presented to individuals. The research was conducted with both visually impaired and sighted groups and compared differences and similarities in perceptual difficulty between these two groups

Designing postgraduate pedagogies: connecting internal and external leaders

Learning is the new resource driving the knowledge economy. Now everyone is expected to make themselves available to learn : un-learn : re-learn. Much has been written about new modes of learning, as well the new technologies that promise to deliver information 24/7. Paradoxically, however, in the field of educational sociology there has been little systematic theorisation of the pedagogies designed to facilitate learning in the knowledge economy. Nor have there been systematic efforts to connect macro economic, technological and social changes to state official policies and institutional pedagogic practices. The Bernsteinian theoretical corpus models the power and control relations generating pedagogic discourses, practices and identities from the macro level of policy formation to the micro level of pedagogic interactions. It is therefore useful in examining the new pedagogies designed to generate the learning resources of the knowledge economy. In this paper, we draw on and extend Bernstein's theory of pedagogic discourse and identities to analyse the design and implementation of a postgraduate unit in educational research. This unit aimed to be: rigorous in disciplinary knowledge, technologically innovative, cost efficient; and responsive to diverse student needs and market contingencies

Advancing Patient Safety in the U.S. Department of Veterans Affairs

As part of a systemwide transformation, the VA formed its National Center for Patient Safety to foster an organizational culture of safety within its nationwide network of hospitals and outpatient clinics. A recent medical team training program designed to improve communication among operating room staff was associated with a reduction in surgical mortality and improvements in quality of care, on-time surgery starts, and staff morale. The program is now being expanded to other clinical units, along with a patient engagement program that prevents errors by facilitating communication relating to patients' daily care plans. A recognition program stimulated facilities to conduct timelier and higher-quality root-cause analyses of reported safety events to identify stronger actions for preventing their recurrence. Other initiatives have reduced rates of health care -- associated infections, patient mortality, and post-operative complications. Success factors include leadership accountability for performance and organizational support for testing, expanding, and adopting improvements

A systematic review of pedagogical approaches that can effectively include children with special educational needs in mainstream classrooms with a particular focus on peer group interactive approaches

The broad background to this review is a long history of concepts of special pupils and special education, and a faith in special pedagogical approaches. The rise of inclusive schools and some important critiques of special pedagogy (e.g. Hart, 1996; Norwich and Lewis, 2001; Thomas and Loxley, 2001) have raised the profile of teaching approaches that ordinary teachers can and do use to include children with special educational needs in mainstream classrooms. Inclusive education itself is increasingly conceived as being about the quality of learning and participation that goes on in inclusive schools rather than simplistic matters of where children are place
