Scientific discoveries concerning the bimodal functioning of the human brain have influenced the creation of a visual literacy methodology program at Iowa State University for future art teachers. Student teachers plan and prepare visual lesson plans designed to reverse the traditional pedagogical reliance on faculties dominated by left hemisphere functions--verbal reasoning, logic, analysis--and to explore and promote skills operating in the right hemisphere of the brain--holistic comprehension, simultaneity, intuition, metaphor. Photographic materials assembled to make a well-formed visual statement are given to students, who are told that these materials are the instructions for their next art assignment. Students are faced with the problems of perceiving the general intent of the visual formation and of constructing a process approach for themselves in response. Mutal satisfaction between teacher and student that the response has been true to the student's unique perception while operating within the visual definition of the lesson plan, along with suggestions from the student that future visual statements may result from the exercise, are regarded as good indications of growth in right hemisphere thinking.
