Supporting Concrete Visual Thinking in Multiplicative Reasoning: Difficulties and Opportunities. Technical Report 88-16.
Kaput, James J.
The Educational Technology Center has attempted to develop a series of computer based learning environments to support the learning and application of multiplicative reasoning. The work and software described in this paper, including the teaching experiment that generated the error phenomena examined, is part of a larger ongoing research project. This document looks closely at certain difficulties occurring when students use a concrete environment to model situations involving multiplication and division of discrete quantities. Student difficulties seem to be the result of incongruences between the students' visual experience and the semantic structure of the situation being modeled. The environments themselves and the context in which the phenomena of interest occurred are described. Then discussed are observed difficulty, theoretical underpinnings, and suggestions for a modified environment. (PK)
