Materials used in conducting a conference workshop on language immersion are presented, including an introductory overview, a guide for observing and analyzing immersion instruction, findings resulting from analysis of the program in question, and the text of a related presentation made at the same conference. The introductory section describes briefly a middle school magnet program in foreign languages (French, German, Spanish) and explains the workshop's purpose as a means for the audience to help analyze the immersion experience and identify effective classroom practices. The second section, a video viewing guide, lists 20 videotapes of classroom instruction (not included here) and provides blank forms for observation of the videotapes. Section 3 summarizes research findings on effective immersion practices and results of analysis of the first 6 years of the program in question and provides definitions for basic terminology of immersion. The final section synthesizes the content of the first and third sections. (MSE)
