A comprehensive approach to teaching Business Chinese online is being developed in the Language Learning Laboratory at the University of Illinois. The courseware consists two complementary parts: a Business Chinese Workbook and a Business Chinese Simulation. The Workbook offers step by step language instruction with sample texts and dialogues, focused exercises, grammar explanations, and vocabulary, while the Simulation presents real-world situations for problem solving through language use. Technical challenges and difficulties in constructing and administrating the courseware on the web are discussed.
