When modeling, the demonstration should be very clear. Steps should be exaggerated so the students will attend to the critical features. When a complex skill is being taught, it is important to ask questions of students to verify their understanding and increase their attention. Steps need to proceed in small increments, with explicit directions. The model may need to be repeated several times.
Effective teaching includes guided practice with prompts and feedback.
Optimal learning is created by preventing incorrect responses and eliciting as many correct responses as possible. With mildly handicapped students, prompted practice is continued until students have demonstrated a very high level of proficiency. Student and teacher can simultaneously observe each other. With higher level skills, prompting can also be done by verbal clues as the student performs behaviors. The one's column.
