Presents a conceptual framework and notation for learner modelling in intelligent tutoring systems based on the computational distinction between behavior, behavioral knowledge, and conceptual knowledge and between the system, the learner, and the system's representation of the learner. Approaches to learner modelling based on a review of the…

This study investigated the effectiveness of different types of feedback content (elaborate versus global) and feedback timing (immediate versus delayed) for learning genetics in a web-based learning environment as a function of learners' prior knowledge. It was hypothesized that learning outcomes of students with low prior knowledge would be…

A considerable amount of the effort and enthusiasm that goes into the development and implementation of technology-mediated learning environments often fails to create effective settings for learning. Too often the opportunities and advantages of the use of technology in the learning process are poorly exploited. This paper explores ways in which…

Describes the Instructional Software Design Project conducted in a LOGO-based learning environment in a Boston inner-city public school with fourth graders engaged in the design and production of educational software to teach fractions. Constructionist views of computers in education are discussed, and learning processes are examined. (Contains 58…

CIRCSIM-Tutor is a computer tutor designed to carry out a natural language dialogue with a medical student. Its domain is the baroreceptor reflex, the part of the cardiovascular system that is responsible for maintaining a constant blood pressure. CIRCSIM-Tutor's interaction with students is modeled after the tutoring behavior of two experienced…

Presents an evaluation of "Smithtown," an intelligent tutoring system designed to teach inductive inquiry skills and principles of basic microeconomics. Two studies of individual differences in learning are described, including a comparison of knowledge acquisition with traditional instruction; hypotheses tested are discussed; and the…

Examines the prospects for learning and education through the use of interactive multimedia technologies (IMT) connected through telecommunications to create distributed multimedia learning environments. Highlights include a theoretical orientation on learning and teaching processes; teachers' roles; implications of learning theory for IMT design;…

Describes a study which measured how ninth-grade students integrated information about mathematical concepts when working with Triple Representation Model software. Tables, graphs, and algebraic functions were linked, allowing students to manipulate several representations of the same concept. Examples of mathematical problems and student case…
