Fluency: A Critically Important Yet Undervalued Dimension of L2 Vocabulary Knowledge

Abstract

Measurements of vocabulary knowledge are powerful indicators of language proficiency, as they correlate with other language skills (Milton 2013;Staehr 2009). It is evident to all L2 educators that L2 vocabulary knowledge is an essential component of L2 competency. The underlying constructs of vocabulary knowledge are generally accepted as consisting of multiple dimensions (Milton 2013). Among these knowledge dimensions, vocabulary fluency, or the ability to access and apply vocabulary knowledge under time constraints, is arguably one of the most important. This is especially the case in regard to the ability to apply existing L2 vocabulary knowledge in a communicatively competent manner. This paper asserts that the ability to apply vocabulary knowledge in a fluent manner has been systemically undervalued in contemporary L2 educational contexts. In support of this assertion, empirical data drawn from the results of two equivalent vocabulary tests administered among a cohort of 113 tertiary-level L2 learners are presented. Results showed significantly lower mean vocabulary scores on the fluency dependent (FD) test than those attained by the cohort on the fluency non-dependent (FND) test. The implications of this significant discrepancy between these two measures of vocabulary knowledge are discussed. The paper concludes that the cohorts' FD knowledge of high frequency and academic words was significantly lower than their FND knowledge of those same categories of words. These results encourage an invigoration of teaching, testing, and
