This paper discusses how to teach the transitive construction for improving communicative competence of primary English learners. Given that sentence-level comprehension (form-to-meaning) and production (meaning-to-form) are two major axes in communication, it is necessary to teach the forms and meanings of English sentences in an integrated way. Thus, we employ Construction Grammar (Goldberg, 1995) as the theoretical framework for form-meaning integration and explore methods of teaching the transitive construction, one of the major argument structure constructions in English. We first propose four principles for teaching argument structure constructions and highlight the characteristics of the transitive construction that primary English learners should be taught. Then, we describe instructional methods and specific activities for teaching the transitive construction to primary English learners. These efforts lead us to conclude that such instruction will contribute to primary English learners’ basic communicative competence and that the forms and meanings of other argument structure constructions also should be taught in integrated ways.
