Develops a theory of mediated learning from practice. Problems inherent in developing theories are reviewed; general assumptions are identified; and a descriptive theory is generated that identifies favorable factors facilitating learning. Factors are checked for consistency and used to generate hypotheses for collecting research data capable of…

This study reports two experiments which indicate that the processes of providing subjects with insightful representations of example programs and guiding subjects through an "ideal" problem solving strategy facilitate learning. A production system model (GRAPES) has been developed that simulates problem-solving and learning in the…

This study examined the relative effectiveness of different media in presenting modeling stimuli to adult trainees in a supervisory skills training program and assessed their satisfaction with the training and their performance. Eighty undergraduate students were randomly assigned to one of four conditions--audio only, text only, audio plus text,…

A prescriptive theory for learning which delivers prescriptions for designing prototypes of instructional materials with different knowledge structures, the Elaboration Theory of Instruction (ETI) is based on important principles and theories of learning and instruction. This paper reports three experiments which tested ETI. The first experiment…
