Compares the knowledge content of GTE (Generic Tutoring Environment), a generic instructional knowledge base that facilitates dynamic pedagogical decision making, and PEPE, a computational framework for representing pedagogical knowledge to tailor instruction to an individual student. The courseware's interaction with the student and instructional…

Compares dyads of secondary school physics students working on a collaborative modeling task using a text-based model representation, in which correct equations are required to make the model run, with others using a graphical representation, in which the model is build by qualitatively linking variables.

Considers claims regarding GTE (Generic Tutoring Environment) and describes how instructional strategies are represented in Eon, an authoring tool for intelligent tutoring systems. Highlights include comparisons of GTE with other formalisms; intended audiences; representing instructional expertise; tradeoffs between generality and inferencing…

Describes the role of natural language processing (NLP) techniques, such as parsing and semantic analysis, within current language tutoring systems. Examines trends, design issues and tradeoffs, and potential contributions of NLP techniques with respect to instructional theory and educational practice.

Tests the effectiveness of CONTACT-2, a revision of CONTACT strategy, which uses continuous, computer-assisted activation of learner conceptions in text processing. CONTACT-2 was found to be more effective as a process-oriented instructional strategy. Student subjects in grades five and six with the CONTACT-2 condition constructed better…

Computer-Supported Intentional Learning Environments (CSILE) is a database system in which learners collaboratively construct the knowledge represented in the database. This study examines how students in a grade-five and -six classroom built their database on a science topic, electricity. Differences in cognitive and operative activities between…
