This article describes the use of fractal simulations of African design in a high school computing class. Fractal patterns—repetitions of shape at multiple scales—is a common feature in many aspects of African design. In African architecture we often see circular houses grouped in circular complexes, or rectangular houses in rectangular complexes. Typically the accompanying ceremonies, cosmologies and other traditions make use of scaling and recursion in their conceptual models. African scaling designs include textiles, sculpture, adornment, and other forms; in many cases there are explicit geometric algorithms and other formal aspects (e.g. pseudorandom number generation in divination systems) embedded in the associated indigenous knowledge system. Thus African fractals provide a strong counter to stereotypes of African culture as primitive or simplistic. Following this fieldwork, we developed a website which uses java simulations of these African designs to teach computational perspectives on fractals to high school students (www.csdt.rpi.edu). We hypothesized that this combination of anti-primitivist ―ethnocomputing ‖ and design-based creative learning would enhance both the engagement and performance of minority students in computing.
