Abstract: The combination of information technology and foreign language teaching has brought a profound reform in the area of language teaching and learning.Interaction has becoming the core of language teaching.But man-machine interaction can not meet the needs of practical communication.This paper,on the basis of the communicative teaching approach and constructionist learning theories,suggests that while using modern teaching technologies,we should step up classroom teaching reform,adjust teaching conceptions,innovate teaching means,improve evaluation methods,incorporate new technologies into classroom teaching so as to carry out teaching reform effectively and upgrade students' English language competence in an all-round way,especially their spoken English.
