Collocations and Action Research is a thorough investigation of both the theory and practice behind improving second language learners' vocabulary and fluency through the teaching of multi-word units of language. Taking these collocations as its focus, this book provides a clear and in-depth description of the cognitive processing language learners go through when producing speech in relation to them. Using the findings of a two-year action research study into improving learners' spoken fluency, Joshua Brook Antle also explores the practical sides of collocations, explaining how the research study was constructed and conducted. Orientating the findings within the larger field of second language acquisition, especially within the L2 classroom, the practical applications of the findings are then presented through a series of pedagogical tasks all focusing on collocations and productive fluency. Providing a template for how to conduct an action research study using both qualitative and quantitative research techniques, Collocations and Action Research will appeal to researchers interested in vocabulary and spoken fluency, as well as language instructors wanting to better understand the nature of vocabulary and spoken discourse.
