| Grammar is the soul of language. Grammar teaching is one of the most important parts in language teaching. Recently the researches both in China and aboard show that grammar teaching plays a positive role in language learning. Spada (1997) found that in the process of communication language learning, the cognitive concept of grammatical knowledge, taught by the teachers, can keep a long time in learners' memory and the accuracy is high during the use of grammatical knowledge. Ellis (2002) proposed that extensive and long-term grammar teaching can facilitate the development of implicit language knowledge. Meanwhile grammar teaching can help the students use the difficult language forms more correctly. Piennemann's hypothesis that grammar can be taught proved grammar teaching can accelerate learners' mastery of language structures. Therefore, Russian teaching should take grammar teaching into consideration.This paper first claims the current situation and the problems, and then based on the constructivism; it proposes Russian grammar teaching principles and teaching models in order to improve the quality of Russian grammar teaching.The Russian grammar teaching models in this paper could make the students not only grasp the grammar principles but also improve the learning interest; develop learners" abilities, such as independent thinking ability, analyzing ability, solving ability; practice students' knowledge construction and generalization abilities; enhance the development of four language skills, which aims to improve learners' language communicative competence. |
