This paper presents both the design and the pilot formative evaluation study of a computer-based problem-solving environment (named LECGO: Learning Environment for programming using C using Geometrical Objects) for the learning of computer programming using C by beginners. In its design, constructivist and social learning theories were taken into…

This research describes preservice teachers' perceptions of the use of applets in solving mathematical problems. It examines such perceptions regarding the role and functions that applets have in the problem solving context, the difficulties they encounter when using applets in this context and the necessity or need of their use. I attempt to…

This article focuses on research findings concerning the relationship between young children's computer use in the classroom and constructivist education. Three ways of using computers emerged: computers as books or workbooks; computers for word processing; and computer programming of graphics. It was concluded that word processing was most…

Teachers College of Columbia University (New York) and the Dalton School, an independent school in New York City, have collaborated on the Dalton Technology Project and its "Archaeotype" program which presents students with a graphic simulation of an archeological site. Students simulate digging up the artifacts, use reference sources to…

Two graphic computer simulations have been prepared for teaching high school and middle school students about how business organizations and financial systems work: "Parkside," which simulates managing a hotel; and "Guestwear," which simulates managing a clothing manufacturer. Both simulations are based on six principles of…
