Numerous researches about the application of mind mapping in teaching reading, writing and vocabulary has got positive findings. Mind mapping has been recommended and adopted in some teaching reference books and students’ reference books. It has been applied increasingly in daily teaching and many students have got a certain understanding about it.

As a kind of new teaching approach, the application of mind mapping in junior high English vocabulary teaching still remains at the primary stage, which needs further study. The empirical research on application of mind map in Chinese classroom is still necessary and instructively meaningful.

With the above said in mind, a teaching practice was carried out in order to see whether mind-mapping-assisted vocabulary teaching can go smoothly in junior high school. What’s more , this paper attempts to analyze the effects of the mind-mapping-assisted vocabulary from the teaching case. 1.2Research Qusetions：
