As the second volume in a 4-volume evaluation report on the University of Massachusetts Non-Formal Education Project (UMass NFEP) in rural Ecuador, this volume details the evaluation design. Cited as basic to the evaluation design are questions which ask: (1) What kinds of effects (changes) can be observed? and (2) What are characteristics of the materials and procedures as they can be logically and/or empirically related to the desirable outcomes? Cited as major components of the design are: (1) The experimental field implementation and concurrent evaluation of the UMass NFEP education games that were among the most widely used/accepted education games; and (2) The UMass non-formal education intervention impact study (an impact profile, a qualitative analysis of intervention based on observations and interviews, and individual testing of game session participants). Additionally, this report describes: (1) Materials Selected for University of California at Los Angeles Field Implementation and Evaluation; (2) Instruments (a set of individually administered tests given in a pre-second-post basis to measure literacy, numerical skills, and critical consciousness or attitudes); (3) Staffing (selection criteria, training, and procedures); (4) Implementation Procedures (selection of communities and control and experimental groups); (5) Criteria for Field Supervision and Quality Control.
