Complex design problems require more knowledge than any single person possesses because the knowledge relevant to a problem is usually distributed among stakeholders. Bringing different and often controversial points of view together to create a shared understanding among these stakeholders can lead to new insights, new ideas, and new artifacts. New media that allow owners of problems to contribute to framing and resolving complex design problems can extend the power of the individual human mind. Based on our past work and study of other approaches, systems, and collaborative and participatory processes, this article identifies challenges we see as the limiting factors for future collaborative human-computer systems. The Envisionment and Discovery Collaboratory (EDC) is introduced as an integrated physical and computational environment addressing some of these challenges. The vision behind the EDC shifts future development away from the computer as the focal point, toward an emphasis that tries to improve our understanding of the human, social, and cultural system that creates the context for use. This work is based on new conceptual principles that include creating shared understanding among various stakeholders, contextualizing information to the task at hand, and creating objects to think with in collaborative design activities.

One fundamental challenge for the design of the interactive systems of the future is to invent and design environments and cultures in which humans can express themselves and engage in personally meaningful activities. Unfortunately, a large number of new media are designed from a perspective of viewing and treating humans primarily as consumers. The possibility for humans to be and act as designers (in cases in which they desire to do so) should be accessible not only to a small group of “high-tech scribes, ” but rather to all interested individuals and groups. Meta-design characterizes activities, processes, and objectives to create new media and environments that allow users to act as designers and be creative. In this paper we discuss problems addressed by our research on meta-design, provide a conceptual framework for metadesign, and illustrate our developments in the context of a particular system, the Envisionment and Discovery Collaboratory.

Self-directed learning is a continuous engagement in acquiring, applying and creating knowledge and skills in the context of an individual learner’s unique problems. Effectively supporting self-directed learning is one of the critical challenges in supporting lifelong learning. Self-directed learning creates new challenging requirements for learning technologies. Domainoriented design environments address these challenges by allowing learners to engage in their own problems, by providing contextualized support, and by exploiting breakdowns as opportunities for learning. Economies of educational knowledge constitute an emerging concept in which communities contribute toward the creation of information repositories, which can be reused and evolved by all members of the community for the creation of new environments. We argue and demonstrate that domain-oriented design environments can serve as models for these economies, that a software reuse perspective provides us with insights into the challenges these developments face, and that the creation and evolution of these economies are best understood as problems in self-directed learning. Keywords: Self-directed learning; lifelong learning; domain-oriented design environments; economy of educational knowledge; reuse; seeding, evolutionary growth, reseeding Demonstrations: A demonstration of the WebNet system described in this article can be found at

Design is a rich domain in which to investigate barriers and biases in computer-supported communication because it involves many different modes of communication in social-technical contexts. This chapter briefly describes different design approaches. It analyzes the biases and barriers of two different types of design communities: communities of practice and communities of interest. To address the communication challenges between diverse design communities, boundary objects are needed to establish common ground and shared understanding in the context of complex design tasks. We explore the unique possibilities that computational media have to support our conceptual framework. Our work is based on the fundamental belief that there is no media-independent communication and interaction—that tools, materials, and social arrangements are always involved in some way in these activities. The possibilities and the practice of design are functions

The power of the unaided, individual mind is highly overrated: The Renaissance scholar no longer exists. Although creative individuals are often thought of as working in isolation, the role of interaction and collaboration with other individuals is critical to creativity. Creative activity grows out of the relationship between individuals and their work, and from the interactions between an individual and other human beings. Because complex problems require more knowledge than any single person possesses, it is necessary that all involved stakeholders participate, communicate, collaborate, and learn from each other. Distances (across spatial, temporal, and technological dimensions) and diversity (bringing stakeholders together from different cultures) are important sources for social creativity. This paper describes conceptual frameworks and sociotechnical environments (derived from the systems that we have developed over the last decade) in which social creativity can come alive. Keywords design, social creativity, spatial distance, temporal distance, technological distance, diversity, communities of practice, communities of interest, division of labor

Complex design problems require more knowledge than any one single person can possess, and the knowledge relevant to a problem is often distributed and controversial. Rather than being a limiting factor, symmetry of ignorance can provide the foundation for social creativity. Bringing different points of view together and trying to create a shared understanding among all stakeholders can lead to new insights, new ideas, and new artifacts. Social creativity can be supported by new media that allow owners of problems to contribute to framing and solving these problems. These new media need to be designed from a meta-design perspective by creating environments in which stakeholders can act as designers and be more than consumers. Keywords conceptual frameworks for creativity and cognition, consumers, designers, impact of new media on design, meta-design, social creativity, symmetry of ignorance Gerhard Fischer 2 KBS Special Issues C&C99 INTRODUCTION______________________________________...

Although software reuse can improve both the quality and productivity of software development, it will not do so until software developers stop believing that it is not worth their effort to find a component matching their current problem. In addition, if the developers do not anticipate the existence of a given component, they will not even make an effort to find it in the first place. Even the most sophisticated and powerful reuse repositories will not be effective if developers don't anticipate a certain component exists, or don't deem it worthwhile to seek for it. We argue that this crucial barrier to reuse is overcome by integrating active information delivery, which presents information without explicit queries from the user, and reuse repository systems. A prototype system, CodeBroker, illustrates this integration and raises several issues related to software reuse.

Abstract—Citizen science is a form of research collaboration

Lifelong learning is an essential challenge for inventing the future of our societies; it is a necessity rather than a possibility or a luxury to be considered. Lifelong learning is more than adult education or training --- it is a mindset and a habit for people to acquire. It creates the challenge to understand, explore, and support new essential dimensions of learning such as: (1) selfdirected learning, (2) learning on demand, (3) informal learning, and (4) collaborative and organizational learning. Lifelong learning requires a deeper understanding of the co-evolutionary processes between fundamental human activities and their relationships and interdependencies with new media. It requires progress and an integration of new theories, innovative systems, practices, and assessment. To make lifelong learning an important part of human life, new intellectual spaces, physical spaces, organizational forms, and reward structures need to be created that allow individuals, groups, and organiz...
