AI research in qualitative modeling makes possible new approaches to teaching people about science and technology. We are exploring the implications of this work for the design of intelligent learning environments. The domain of application is electrical circuits, but the approach can be generalized to other subjects. Our prototype instructional system is(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)
Wayne State University was the site of one of the initial experiences with combination chemotherapy, radiation, and surgery for carcinoma of the thoracic esophagus. This review analyzes all the patients seen with thoracic esophageal carcinoma from 1980 to 1984 inclusive, plus an additional 22 patient pilot study. The great majority of patients seen were(More)
Recombinant human TSH (rhTSH) is known to stimulate 131I uptake and thyroglobulin (Tg) release from the postoperative remnant and metastases in thyroid cancer patients, but its effects on serum thyroid hormone and Tg concentrations in normal subjects have not been reported. Before using rhTSH in the management of thyroid disorders other than cancer, the(More)
Acknowledgments I would like to thank the eighth grade students who participated in this research. Without them, this dissertation would not exist. Their teacher, Doug Kirkpatrick, has helped me in more ways than I could ever nameÑespecially by being such a wonderful teacher and role model. I am grateful to my advisor, Marcia Linn, whose insight and(More)
To develop the expertise needed for lifelong learning, we argue that students need to reify, reflect on, and improve their cognitive, social, and metacognitive processes. Introducing software advisors that incorporate models of such processes has the potential to facilitate students' sociocognitive and metacognitive development. To this end, we 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)
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)
