A process that could facilitate a cross-cultural learning environment was designed. The process involved (1) developing motivational devices using an historical selection process that incorporated a "significant difference", evaluated reconstructed historical materials, devices that prevent a "past-present" dichotomy, directional and enculturative mechanisms, and designs for internalizing conceptual perspectives and thought systems; (2) creating a deliberate curriculum design which integrated those multi-cultural learning systems that best facilitated the teaching-learning environment in which the motivator was to be applied; and (3) setting up evaluation and accountability mechanisms through the use of instructional objectives and thought process variation. Most of the units were field-tested in grades K-12. Although all the units use Pre-Columbian, Meso-American materials and concepts, each unit has a basic focus in a discipline, i.e., history, social science, mathematics, fine arts, and language arts. Each unit has an accompanying bibliography and sample activities or backup materials. Units are: (1) Patolli, a Game of Strategy (English and Spanish versions); (2) Pre-Columbian Map Games; (3) Meso-American Man and the Domestication of Plants--Juego de Maiz; (4) Design Unit (English and Spanish); (5) Mythology (English and Spanish); (6) "Atl Atl" (TM) Unit; and (7) Calendar Unit (English and Spanish).
