CHAPTER FOUR RESULTS Language is a vehicle of social interaction, and as such cannot be understood or analyzed as an isolated entity, apart from the larger social context in which it is used. The variety of methods for data collection and analysis used in this study are complementary; together, they provide a more comprehensive picture of the interaction of the students within the systems established by the community and the school than any single method could provide. By highlighting these interactions, some of the forces facilitating or inhibiting the second language acquisition of the students in this study can be observed. Erickson (1981) believes that the most essential contribution of ethnographic research is its use of key descriptions and functionally descriptive terms to convey an understanding of the social context. Ethnography uses key incidents to illustrate the more abstract principles of social organization. Methods of social science research have often been modeled after methods used in physics and other hard sciences. Research designs in the hard sciences are intended to present point values of variables, while research designs measuring human behavior are more concerned with predicting probable differences. Second language acquisition theory must be based on more than mathematical probabilities; it must be founded on the realities of human experience. Ethnographic research utilizes a great deal of contextual information to support the propositions tested (Pelto & Pelto, 1970). 115
