Chapter 12
Discussion, limitations, and future research
This chapter synthesizes the results of the six meta-analyses (Chapters 3, 5, 6, 8, 10, and 11) included in this volume and interprets the findings in reference to the theories and models of L2 proficiency and assessment. We first review influential theories and models of L2 proficiency starting with Spearman’s (1904, 1927) and Oller’s (1979) unitary view of language proficiency, leading to the most recent, Hulstijn’s (2015, 2019) core-periphery model. We then discuss the findings of 4 meta-analyses which reported on the correlations between each of the four L2 skills and its external correlates. Next, we discuss the findings of 2 meta-analyses which reported on the correlations between productive L2 skills (writing and speaking) and their internal correlates. The chapter then discusses the limitations and future research directions.
