This study used secondary education students to investigate three instructional design variables hypothesized to improve rule learning. Results show structuring information by a schematic analysis improves learning over taxonomic analysis; response-sensitive sequency adapting instruction for generalization, then discrimination, improves learning;…

Analyzes rehearsals to determine how teachers with varied levels of training and experience conformed to the optimal sequence. Finds that teachers spent too little time in correct sequences and failed to use enough positive reinforcement. (Author/LS)
