Some of the tools I have developed for my classes include: the perspective clock, a see-through clock face with cross hairs to read angles: a box figure, affectionately named Carlotta, which can show contraction and expansion of the main parts of the human form: and a series of dance leotards on which I have drawn cross contour lines, muscles and plane breaks for the model to wear.
I developed many exercises for the painting class which help to break the difficult art of oil painting into simpler steps. When I see students struggle I know I haven't explained the process correctly. When they paint easily and joyfully their success means the work I've put into the exercise has paid off. Exercises free both the student and the teacher to reach deeply into the process as shared vocabulary and the parameters of the problem are understood and mastered before moving on to another concept. Exercises do not stifle creativity, in fact just the opposite occurs. Creativity is infinite play in a limited space, and without some containment of possibilities chaos can quickly overtake the process. Give an exercise to twenty five students and you have twenty five solutions. Without parameters the same twenty five students' work tend to show the same amateur approaches and faults: mixing muddy colors, pushing far and near objects to the same plane, no control of the edges, and haphazard brushwork. With specific exercises awareness is brought to all these issues quickly and the student moves ahead to more complex ideas.
