The selection of appropriate teaching models with which to bring about meaningful learning is an important and fundamental concern of the professional educator. This paper describes the development of a matrix of models and effects that was a three step process involving the compilation of a list of effects; the development of effect categories by model and domain; and the development of a matrix of models and effects. This project culminated in the creation of a data retrieval chart which allows the user to access information pertaining to teaching models based on instructional and nurturant effects classified by learning domains.
