As the third volume in a 4-volume evaluation report on the University of Massachusetts Non-Formal Education Project (UMass NFEP) initiated in rural Ecuador in 1973, this volume presents an in-depth analysis of the evaluation findings. Since UMass NFEP was initiated for purposes of developing new materials and methodologies in conjunction with and in support of existing Ecuadorian non-formal education programs, these findings are presented in terms of 13 basic evaluation questions relative to the following materials and methodologies: (1) the implementation process; (2) the degree to which project objectives were met; (3) the intent of the project; (4) the learning outcomes of educational games designed to promote numerical skills, literacy, and critical consciousness; (5) the characteristics of the more and less effective materials; (6) the characteristics of materials that worked well with learners of specific characteristics; (7) the facilitator/teacher variables; (8) the motivational attributes of each of the four games selected for in-depth experimental evaluation; (9) the change in attitudes and behaviors produced by each of the selected non-formal education games; (10) the importance of game sequencing factors; (11) the effect of replay frequency for each of the games; (12) the replication possibilities for the project; (13) the components for development of materials and programs in countries similar to Ecuador.
