基于行为主义和建构主义两大学习理论,可以重新审视二语习得中的输入输出,在行为主义学习理论的指导下保证足量的输入,在建构主义学习理论的指导下鼓励高质量的输出。结合大学英语视听说的教学,探讨这一交叉理论视角下的视听说教学新模式,在指导非英语专业大学生的外语学习和实践中有重要的理论及现实意义。 Based on the two learning theories of behaviorism and constructivism, we can reexamine the input and output in second language acquisition, ensure a sufficient amount of input under the guidance of behavioral learning theory and encourage high-quality output under the guidance of constructivist learning theory . Combining with the teaching of college English listening and speaking, it is of great theoretical and practical significance to explore a new mode of audio-visual teaching under the perspective of this cross-theoretical theory in guiding non-English majors in foreign language learning and practice.
