The goal of the POR FIN research design was to develop a language-based curriculum emphasizing the audiolingual approach and integrating academic and social-functioning subject matter. The modular curriculum is designed so that each lesson is independent and complete in itself, and provides a high degree of motivation, retention, and achievement for the undereducated bilingual adult. The document is divided into three major sections. The first section describes the research methodology employed, the structure of each lesson, and the measurement and statistical devices utilized in the study. The analysis and presentation of the controlled experiment's test results are offered in part 2. Four student performance measurement devices and other variables are described and analyzed to evaluate the POR FIN curriculum. They comprise a passive language and math test, a self-concept rating scale, a language proficiency rating scale, and a social-functioning test. Data from administrator, teacher, and student questionnaires are analyzed. In part 3, results of the study are interpreted. Conclusions reached were that the experimental group achieved better results in the following areas: (1) retention was higher, (2) testing recorded greater achievement, and (3) questionnaires recorded significantly positive reactions. The appendix offers over 100 pages of data analysis and the testing instruments utilized. (MW)
