Based on information gained in an interview with a 12-year-old girl in grade seven, a rational reconstruction of the student's problem-solving strategy is proposed and compared with the strategies normally prescribed in contemporary school mathematics textbooks. (Author/CHC)

Describes a programming environment called Tinker, in which a beginning programmer presents examples to the machine, distinguishing accidental and essential aspects of the examples. Examples of programming in Tinker are presented in which programmers demonstrate how to handle specific examples and the machine formulates a procedure for handling…

Research on intelligent tutoring systems is discussed from the point of view of providing moment-by-moment adaptation of content and form of instruction to the changing cognitive needs of individual learners. Implications of this goal for cognitive diagnosis, subject matter analysis, teaching tactics, and teaching strategies are analyzed. (Author)

Compares the expert, spiral, and reading approaches to instructional strategies for introductory computer programming courses. Based on ACT (Adaptive Control of Thought) theory and relevant research, the differences between declarative and procedural instruction are identified, and six tactics used to design courses and evaluate strategies are…

Discusses the structure of a problem-based curriculum based on the complexity of the problems that the students must solve, taking into account the level they must attain and their previous experience with problem-based teaching. This approach is compared with the conventional teaching methods. Twenty-two references are listed. (CHC)

Analyses of students' social and motivational interpretations of interaction during classroom teaching and learning are reported. The interactive learning was organized according to the principles of a cognitive apprenticeship and applied to a technology-based learning environment. The purpose as to promote the mediation of modern technological…

Uses a "teaching as problem solving" perspective to examine the components of metacognition underlying the instructional practice of seven experienced and seven beginning secondary-school mathematics teachers. Data analysis of observations, lesson plans, videotapes, and audiotapes of structured interviews suggests that the metacognition of…
