Design is a critical to the successful development of any interactive learning environment (ILE). Moreover, in technology enhanced learning (TEL), the design process requires input from many diverse areas of expertise. As such, anyone undertaking tool development is required to directly address the design challenge from multiple perspectives. We provide a motivation and rationale for design approaches for learning technologies that draws upon Simon's seminal proposition of Design Science (Simon, 1969). We then review the application of Design Experiments (Brown, 1992) and Design Patterns (Alexander et al., 1977) and argue that a patterns approach has the potential to address many of the critical challenges faced by learning technologists.

This paper reports findings from a survey and interviews with children aged 11201316 years, teachers and parents on their attitudes to e-safety in relation to social networking and media creation (Web 2.0) and their practices at school and at home. The results showed that 74% of the children surveyed have used social network (SN) sites and that a substantial minority regularly interact socially online with people they have not met face-to-face. Online interaction forms a different, although overlapping, social space to that of face-to-face friendships. Despite a desire from some teachers to explore the benefits of Web 2.0 for creative and social learning, they report being constrained by a need to show a duty of care that avoids worst-case risk to children, to restrict access to SN sites. The respondents also report more direct concerns about Internet bullying and exam cheating. We also report a Policy Delphi process with a panel of 30 people with expertise in Web 2.0 and e-safety. The panel reached a general consensus that schools should move towards allowing access to Web 2.0 sites, with children being educated in responsible and creative learning.

The use of design patterns is now well established as an approach within the field of software systems as well as within the field of architecture. An initial effort was made to harness patterns as a tool for elaborating the design of the elements of personal learning environments as part of the University of Bolton's Personal Learning Environment project; however, this earlier effort had a number of limitations that prompted a revisit to the pattern language documented here. In particular, the initial patterns, while functionally useful, lacked some of the moral and generative qualities that are the essential qualities of an effective pattern language. This paper presents a revised pattern language focused around two primary categories, learning networks, and personal learning tools.

Technologically enhanced learning environments raise complex challenges for their designers, developers and users. Design patterns and pattern languages have recently emerged as a potential framework for addressing some of these challenges. However, the uptake of design patterns has been slow outside of the computer science community. We argue that this is largely a consequence of a weak positioning of pattern languages, as a form of delivering expert knowledge to layperson, and suggest an alternative view: the development of a pattern language as a community endeavour. In terms of open education, the workshop model can be viewed as an open production process for developing educational resources, in our case design patterns. We propose a model of pattern elicitation workshops, in which collaborative development of a pattern language provides a framework for sharing design knowledge within interdisciplinary communities. This model was iteratively developed at five international conferences. It was then postulated as a design pattern itself, encompassing a series of practices and a set of supporting tools. We believe this model could be applied in a broad range of communities concerned with the development of open digital educational resources.

The second of three books published by the Center for Environmental Structure to provide a "working alternative to our present ideas about architecture, building, and planning," <I>A Pattern Language</I> offers a practical language for building and planning based on natural considerations. The reader is given an overview of some 250 patterns that are the units of this language, each consisting of a design problem, discussion, illustration, and solution. By understanding recurrent design problems in our environment, readers can identify extant patterns in their own design projects and use these patterns to create a language of their own. Extraordinarily thorough, coherent, and accessible, this book has become a bible for homebuilders, contractors, and developers who care about creating healthy, high-level design. "Brilliant....Here's how to design or redesign any space you're living or working infrom metropolis to room. Consider what you want to happen in the space, and then page through this book. Its radically conservative observations will spark, enhance, organize your best ideas, and a wondrous home, workplace, town will result"San Francisco Chronicle. A handbook designed for the layman which aims to present a language which people can use to express themselves in their own communities or homes, and to better communicate with each other.

One of the important themes that emerged from the CAL’07 conference was the failure of technology to bring about the expected disruptive effect to learning and teaching. We identify one of the causes as an inherent weakness in prevalent development methodologies. While the problem of designing technology for learning is irreducibly multi-dimensional, design processes often lack true interdisciplinarity. To address this problem we present IDR, a participatory methodology for interdisciplinary techno-pedagogical design, drawing on the design patterns tradition (Alexander, Silverstein & Ishikawa, 1977) and the design research paradigm (DiSessa & Cobb, 2004). We discuss the iterative development and use of our methodology by a pan-European project team of educational researchers, software developers and teachers. We reflect on our experiences of the participatory nature of pattern design and discuss how, as a distributed team, we developed a set of over 120 design patterns, created using our freely available open source web toolkit. Furthermore, we detail how our methodology is applicable to the wider community through a workshop model, which has been run and iteratively refined at five major international conferences, involving over 200 participants.
