This paper describes the theoretical underpinnings and architecture of a new type of learning environment that incorporates features of microworlds and of intelligent tutoring systems. The environment is based on a progression of increasingly sophisticated causal models that simulate domain phenomena, generate explanations, and serve as student models.(More)
To develop lifelong learning skills, we argue that students need to learn how to learn via inquiry and understand the sociocognitive and metacognitive processes that are involved. We illustrate how software could play a central role in enabling students to develop such expertise. Our hypothesis is that sociocognitive systems, such as those needed for(More)
One promising educational application of computers derives from their ability to dynamically simulate physical phenomena. Such systems permit students to explore, for instance, electrical circuit behavior or particle dynamics. In the past, these simulations have been based upon quantitative models. However, recent work in artificial intelligence has created(More)
We introduce a method for promoting reflective conversations during collaborative work which enables participants to explore their cognitive goals and processes and thereby develop a metacognitive understanding of their practice. This method, termed "cognitive facilitation," seeks to provide a conceptual and linguistic basis for metacognitive reflection by(More)
A prototype Web-based environment, called the Web of Inquiry, was developed that built on previous work in science learning and technology. This new system was designed to meet constructivist-learning principles, support self-reflection, and meet specific interaction goals within the classroom environment. The system was tested it in fifth, sixth, and(More)
