According to the constructivist learning theory, knowledge is not absorbed through teachers’ analysis, but with the help of teachers and classmates. Situational context should be beneficial for the learners to construct the learning materials. In situational context creation, they can form the multi-construction of language. The teaching design does not start from the analysis of teaching objective but from how to create the beneficial situational context. The teachers can create a suitable context for different studying characters, which can strengthen the learners’ knowledge constructing abilities. The Constructivist learning theory is an important basic guideline of the new curriculum reform. As the modern educational theory and educational technology develop, the constructivist learning theory will play a more and more important role in English teaching and learning.
