Studying Chinese is in hot demand around the world these days. However, much of the course materials utilized at colleges in the United States have not kept pace with the technology evolution over the last decade.
We at ActiveChinese, Inc. aim to design a highly interactive curriculum for Chinese learning. The Textbook is designed to advance a learner from the absolute beginner level to the advanced beginner level. The curriculum consists of interactive multimedia learning materials such as drills, self-assessment tests, grammar points, vocabulary builders, and character writings.
