All language dialects are legitimate but some dialects achieve social prestige. Standard American English (SAE) represents that language in the United States. Minority students who do not learn SAE do not achieve academically as well as those who do. The dialect individuals use is determined by income, social class, ethnic group, and level of education. The failure to speak SAE effectively represents a barrier to those who speak less prestigious dialects such as Black English or Spanish Influenced English. This booklet is designed to be used by the classroom teacher to raise the cultural sensitivity of the instructor and to serve as a model for more effective teaching of SAE to minority students. Various tests and suggestions for lesson plans are provided, and a cultural bias self-test is included. Examples are given of test biases and communication differences, along with information on how to manage student misbehavior by teaching school norms. A 29-item bibliography concludes the document.
