Applying the ATI concept in an operational environment

SummaryThe procedure presented in this article is an attempt to synthesize recent thinking about the design of ATI studies and the development of alternative treatments, with the explicit purpose of deriving a method that can be implemented in an operational instructional environment. In addition, an attempt was made to conceptualize ATI research as feasible for implementation as part of a dynamic decision-making instructional environment in which one considers the appropriateness of alternative module development in light of empirical data on the performance of a single main track of instruction. The proposed working model will hopefully allow those concerned with individual differences in the classroom to apply limited resources where individualization is most needed.
