Enabling students’ knowledge building in English classrooms in China: The role of teacher monologue

Abstract

Abstract Teacher monologue has received scant attention in English as a foreign language (EFL) classrooms which emphasise the teacher-and-student exchange. This study assumes that a key index of interaction would be the construction of knowledge, in which teacher monologue has a due role to play. The research is set in the context of EFL teaching at the tertiary level in China and examines teacher monologue with reference to the concept of making semantic waves in Legitimation Code Theory, which has been proved to be an important means of cumulative knowledge building in classroom practice. Systemic Functional Linguistics is used to analyse how semantic waves are generated on the ideational base of context dependency, i.e. the extent to which the reality construed in teacher monologue is dependent on its context. The transdisciplinary perspective attempts to provide one possible way to model linguistic choices in making semantic waves in EFL classrooms. The findings are the primary and secondary categories of semantic patterns representing a scale of context dependency. Semantic waves trace recurrent movements between relatively decontextualised and context-dependent meanings in the progression of semantic patterns. The shifts might scaffold students in the construction of knowledge essential for developing academic English proficiency.
