29 The educational ethnographer's task is to sort through the highly visible elements of cultural differences found in the school setting and interpret the subtle, but highly significant way that participants view events so those interested in the research can understand (Geertz, 1973; Wolcott, 1980). The second part of this section reviewed research on socio linguistics and second language acquisition. Under natural learning conditions the process of learning a second language is much like learning the first. However, adults and teenagers learn the school - instructed elements of language much faster than younger children (Ervin-Tripp, 1978). Adults are more conscious of grammar (Krashen, 1978). The social setting is an important motivating factor (Fillmore, 1976) in second language learning. Adults who feel psychologically or socially distant from the speakers of the target language learn the language much more slowly, if at all (Schumann, 1978). The political position of the language in relationship to the learners is very im portant (Edelsky & Hudelson, 1980). Troike (1981) and Cummins (1981) emphasize the need to break down social and cultural barriers to facilitate second language learning. Canale (in press) presents a framework for defining communicative proficiency. Damico et al. (1981) believe pragmatic and surface- oriented criteria are important. Burt and Dulay (1978) emphasize the need for distinguishing between naturalistic and linguistically manipu lative tasks. Rodriguez-Brown (1979) finds that educational treatments greatly influence educational achievements on measures of reading.
