Developments over the last three decades provide momentum for revising high school geometry instruction as recommended by the van Hieles. Cognitive learning theories, brain research, multiple intelligence theories, revised national and state standards and computer technology-based tools all contribute to the rationale and the means to deliver instruction that enables students to construct knowledge and understanding through a sequential process of exploration, inductive and deductive reasoning. A Regents Geometry unit on quadrilaterals was developed based on these theories and techniques. Forty-three students enrolled in the high school Regents Geometry course received instruction using the newly developed materials. The results of these students showed improvement over the results of the previous year's students under more traditional geometry instruction.
