Adults have their own advantages of learning Chinese.
Considering the advantages and weakness of adults learning Chinese, I will take several methods as below:
The first, I will hang out the Pinyin table, taking about ten minutes to pronounce the Pinyin repeatedly, which will strengthen the connection between the phonetic notation and Pinyin.
The second, considering the reluctance of speaking out, I will give a topic to discuss after class. For example, talking about your family, what they do and what are their plans in the near future.
The third, adults will pay more attention to the class than children. I suggest that the class is 2 hours long and 3 times a week, which I believe will help them learning more efficiently.
The last, based on the needs, I prepare some materials for adults to learn, like some popular business Chinese and introductions about some occupations.
I will summarize some useful experience and share it with you and keep on doing my best to make my class full of interest!! Thank you.
