The Hawaii English Project (HEP) was established to redefine the basic English program in Hawaii schools. Planning teams used a systems approach to solve the problems of language instruction. Instructional designs and materials were produced and tested on students. Analysis of variance was performed on test results. Conclusions are: (1) the HEP curriculum has been tested with a sufficiently representative sample of elementary school children and teachers that the findings can be generalized for elementary schools throughout the state; (2) The program has been commended by the principals of participating schools, visitors to experimental classrooms, and professionals in several educational fields.
