This paper presents materials used in a "short course" on using Ebonics and bilingual code switching to facilitate clarification interactions in communication classrooms and multicultural public speaking. After beginning with a detailed agenda for the two-and-a-half hour short course, the paper presents seven speech communication principles for facilitating message clarification interactions in culturally diverse contexts; a model of multicultural collaborative communication; eight references; a description of multicultural public speaking communication variables; a newspaper article on Ebonics ("95th Street: Ebonics in Real Life" by Amy Pyle); a three-way message clarification interaction worksheet; and a sample form (and the dyad's copy) for facilitating nonstandard American English message clarification interactions. Next, a three-step procedure for analyzing public speaking multicultural message clarification interactions and an evaluation form for public speaking multicultural message clarification are presented. An appendix contains a non-context-specific multicultural collaborative communication model, extra sample forms and evaluations, and another newspaper article on Ebonics ("Defining Who We Are in Society" by David Dante Troutt).
