The task-based teaching method is effective in helping foreign learners to study Chinese. About the task choosing and classification, Candlin proposed a series of standards, including cognitive load, communication pressure, specifically and universality, code complexity and understanding density as well as the continuity of the process. If teachers can deal with these properly when foreigners study Chinese, they can learn it effectively because of the proper understanding of the task-based teaching method.

What’s more, when dealing with the tasks of language teaching, Long emphasized the importance of analysis of the requirements. Teachers in Chinese language program in China should know that the tasks should be closely related to students‘ needs to communicate in the future. Therefore, the task of imitating the real world should be assigned. In addition, Long also developed the interaction theory on the basis of the theories of the second language learning. The task-based teaching is suitable and feasible to help the foreigners study Chinese. In the process of finishing the tasks, the learners can acquire language skills.
