In 2002, the National Science Foundation established the Network for Computational Nanotechnology (NCN), a network of universities supporting the National Nanotechnology Initiative by bringing computational tools online, making the tools easy to use, and supporting the tools with educational materials. Along the way, NCN created a unique cyberinfrastructure(More)
We discuss computer environments that invite students to learn by instructing " teachable agents " (TA's) who venture forth and attempt to solve problems that require knowledge of disciplines such as mathematics, science or history. If the agents have been taught properly they solve the problems they confront; otherwise they need to be further educated. The(More)
The National Science Foundation-funded Center for Innovative Learning Technologies (CIL T) is designed to be a national resource for stimulating research and development of technology enabled solutions to critical problems in K-14 science, math, engineering and technology learning. The Center, launched at the end of 1997, is organized around four themes(More)
This article explores how insights from the learning sciences can guide the effective use of computer technologies to promote learning and how these technologies make new types of learning opportunities possible. The discussion is organized to provide three illustrations of how the introduction of new technologies can have " ripple effects " that influence(More)
Education in biomedical engineering offers a number of challenges to all constituents of the educational process-faculty, students, and employers of graduates. Although biomedical engineering educational systems have been under development for 40 years, interest in and the pace of development of these programs has accelerated in recent years. New advances(More)
New information technologies promise to enhance engineering instruction by facilitating the learning process. A preliminary study examines the use of a tablet PC as a presentation platform for problem-solving methodologies used in a fourth year Mechanical Engineering class of 50 students. Typical presentation methods used in large-scale classroom settings(More)
Many courses adopt a traditional approach to instruction, characterized by lectures that follow a linear progression through a textbook that is organized about the general taxonomy of the subject matter. New theories of learning suggest that this taxonomy-driven instruction offers fewer opportunities for students to develop their problem solving abilities(More)
The goal of this paper is to describe our initial efforts at developing what we call " interactive analogies. " Interactive analogies are pairs of simulations. In the attempt to answer specific problems, students interact with each simulation and map the analogous structures in each. Interactive analogies provide a complementary use of analogies and(More)
