The paper briefly describes the research foundations of the curriculum at the University of Tulsa (Oklahoma) School for Gifted Children with emphasis on the arts component. The school, serving children from 3 to 11 years of age, bases its curriculum in Enaction Theory originated by S. Ohlsson (1983). The theory stresses the enhancement of thinking through three steps: (1) developing a representational mental model, (2) manipulating that model, and (3) developing rules (heuristics) that lead to a strategy for problem solving. The Rainbow Day Curriculum is an entirely arts based curriculum which is conducted 1 day a week at the school. The program attempts to help students develop an appreciation of a broad spectrum of art work through critical evaluation of art work reproductions representing the three approaches to art of imitationalism, emotionalism, and formalism. Included are a bibliography of 11 items and handouts describing a taxonomy of thinking based on enaction theory, the three approaches to art, and guidelines for art criticism. (DB)
