Abstract
This paper describes the on-going research and development activities of the PRODIGY project. The major aim of this project is to develop inteUigentcomputer-based simulation systems which facilitate the develOpment of high leveldi~gnostic andremediation skills in the domain of common fractions. The development and the functioning of the present generation of PRODIGY simulation systems (PRODIGY] ) is The methods used in and results from the formative evaluations of the PRODlGYI generation of simuiation systems then are described. Some of the modifications which had their genesis in thetesults from theformative evaluations are briefly discussed. Three serious limitaiionsof the PRODIGY] simulation,' are. identified and discussed. The paper concludes with a description of the architecture 0/ next generation of PRODIGY slmulations together with a discussion about how It is hypothesized that they willovetcome the serious limitations o/the PRODIGY] simulations.
