Method Learning task Treatment factors Aptitude information Measure of payoff Subjects ProcedureResults and Discussion Significance tests of ATI effect and main effect Generality-specificity problem Determination of optimal instructional treatment with two aptitude informations and four treatments Determination of optimal instructional treatment with single aptitude information and four instructional treatments Improvement of payoffs yielded by optimization using two aptitude informations and single oneConcluding remarksThe present experiment was designed to complete a series of ATI research on establishing a method for determining the optimal instructional treatment when two aptitude informations and multiple treatments are combined. Under four types of instructional treatments, Text-Numerical, Text-Graphical, Program-Numerical, and Program-Graphical, junior high school pupils were taught a learning task of understanding and applying a formula to summate arithmetic progression. Six aptitudes were measured including specific and general ones. By revising the pretest and the measure of payoff used in the preceding experiment, more decisive conclusions were drawn that specific aptitude informations were more advantageous in yielding significant ATIs than general ones, quite contrary to the result of the similar preceding experiment. Possible causes of this discrepancy were discussed in relation to the subtlety ATI has.
