This document focuses on the behavior influence process as it is related to modeling and role playing applied in classroom settings. The topics discussed are divided into six sections, with an "Introduction" and "A Final Word.""What Is Modeling?" describes some basic conclusions about modeling reached by behavioral and learning researchers. "How Modeling Works" includes discussions on topics such as assertive training and modeling to change undesirable behavior. "Applying What Has Been Learned about Modeling to Delinquents" uses scripts to apply modeling theory to problems such as school dropouts and homework. "Teachers Can Model, Too" discusses ways teachers can use other teachers as models, including meeting with especially able teachers in an informal setting and discussing written descriptions of how particular teachers have succeeded in school situations where the odds did not appear favorable. Also listed are some hints about observational learning in the classroom. "Modeling for Vocational Training" illustrates how modeling can be applied to vocational education and training. "A Review of Modeling Principles and Practices" lists and describes the elements of modeling such as attention, role playing or behavior rehearsal, retention and transfer of training, and motivation.
