This Basic Course attempts to provide samples of two different Cambodian dialects--Standard Cambodian, the approved speech style of public education and mass communication, and the dialect of Phnom Penh. The material is arranged in groups of five units with a common theme. The first four units of each sequence are based on Dialogs, usually in the Phnom Penh dialect, and the fifth is based on a Narration, in Standard Cambodian, which reviews the immediately preceding subject matter. The text for Units 1-20 is entirely in standard style. From Unit 21 on, most of the text is given in Phnom Penh dialect (except for the Narrations), but a parallel Standard version of each Dialog is provided in the Dialog for Comprehension. Vocabulary lists include both forms wherever there is a difference. A typical unit includes a Dialog or Narration, cultural and grammatical notes, and extensive pattern drills. All Cambodian material is written in phonemic transcription. See AL 002 470 for Volume Two. Tape recordings for both volumes are available from the Sales Branch, National Audio Visual Center (GSA), Washington, D.C. 20409. (Author/JD)
