This book is about the implications of constructivism for instructional design practices, and more importantly, it is about a dialogue between instructional developers and learning theorists. Working with colleagues in each discipline, the editors were amazed to find a general lack of familiarity with each others' work. From an instructional design perspective, it seems that the practice of instructional design must be based on some conception of how people learn and what it means to learn. From a learning theory perspective, it seems obvious that the value of learning theory rests in the ability to predict the impact of alternative learning environments or instructional practices on what is learned. Thus the interchange of ideas between these disciplines is essential. As a consequence of both the information rich environment and the technological capability, business is seen moving away from a fixed curriculum and toward providing information and instruction when it is needed. These changes bring about a window of opportunity establishing a dialogue that will provide for a richer understanding of learning and the instructional environment required to achieve that learning. The editors hope that this book is the beginning of the conversation and that it will serve to spur continued conversation between those involved in learning theory and those involved in the design of instruction.

Constructivist Instruction: Success or Failure? brings together leading thinkers from both sides of the hotly debated controversy about constructivist approaches to instruction. Although constructivist theories and practice now dominate the fields of the learning sciences, instructional technology, curriculum and teaching, and educational psychology, they have also been the subject of sharp criticism regarding sparse research support and adverse research findings. This volume presents:

• the evidence for and against constructivism;
• the challenges from information-processing theorists; and
• commentaries from leading researchers in areas such as text comprehension, technology, as well as math and science education, who discuss the constructivist framework from their perspectives.

Chapters present detailed views from both sides of the controversy. A distinctive feature of the book is the dialogue built into it between the different positions. Each chapter concludes with discussions in which two authors with opposing views raise questions about the chapter, followed by the author(s) responses to those questions; for some chapters there are several cycles of questions and answers. These discussions, and concluding chapters by the editors, clarify, and occasionally narrow the differences between positions and identify needed research.

Learner-Centered Theory and Practice in Distance Education: Cases From Higher Education brings the voice of the learning sciences to the study and design of distance learning. The contributors examine critical issues in the design of theoretically and pedagogically based distance education programs. Eight distance education programs are described in enough detail to allow readers with different interests to understand the pedagogical approaches and the implications of implementing those approaches. Issues of theory, pedagogy, design, assessment, communities of practice, collaboration, and faculty development are discussed. Each section of the book includes: *a primary chapter written by an author or authors involved with a distance education program that reflects learner-centered principles; *a formal reaction to the chapter by a specialist from the learning sciences, educational evaluation and policy, administration, or the corporate sector with expertise in issues of distance learning; and *an edited transcript of the authors' discussion of the primary chapter held at a symposium at the Asilomar Conference Center. A final "summing up" section offers two perspectives--from leading scholars outside the fields of instructional design, evaluation, and the learning sciences--on the approaches and thinking reflected in the rest of the book. This book is essential for researchers, as well as all those engaged in delivering, supporting, or administrating distance education programs at the post-secondary level. The descriptions, strategies, and principles will inform the design of continuing education, as well as degree-based education and corporate education and training, and distance education programs for adults.

The idea for this book grew out of a NATO Advanced Research Workshop held at the Catholic University at Leuven, Belgium. We are grateful to NATO for support in conducting this workshop and for support in the preparation of this book. We are particularly grateful for their emphasis on designing the workshop to build collegiality. They suggested that we hold the meeting in a small town and that we organize evening activities to keep the group together and to promote informal and extended discussions. What sage advice. The excitement grew over the three days as we shared understandings and enriched our perspectives. Indeed, there was even a proclaimed "near" conversion to a constructivist perspective from one colleague trained in traditional instructional design methods. While we report this as a bit of a humorous anecdote, it most clearly reflects the sense of excitement that developed. We would also like to thank the staff at the Catholic University for their great support during the workshop. Their efforts and their good cheer were important components in the success of the meeting. In particular we would like to thank Jan Elen, Catherine Vermunicht and Jef Vanden Branden. Finally we would like to thank the personnel at Indiana University for their help in assembling this book. Deborah Shaw prepared the index. We thank her for the skill and speed with which she was able to work.
