In our country＇ s university English teaching, it uses the translation law. This law mainly teaches English grammar elementary knowledge and mother tongue English translates the method mutually. The teacher attends class with the mother tongue does not need English to carry on the explanation as the classroom instruction quite is easy to grasp. The direct method requests the teacher to teach with the skillful English, does not have to use the mother tongue but because the student hearing level is irregular. Cognitive theory believes that the process of language learning is the process of combining old and new knowledge, and language ability from the theoretical knowledge into the application of automatic process. Therefore, we make the integration of the mentioned items and propose our novel teaching paradigm which is effective.展开更多
