Connections between measured and assessed fluency in L2 peer interaction: a problem-solving perspective

Abstract This article examines the connections between ratings and measures of second language (L2) fluency based on dialogue data, extending previous studies on L2 individual fluency. The links between fluency and strategic competence are studied from a problem-solving perspective. Fifteen raters’ assessments and comments of individual fluency, interactional fluency, and strategic competence based on six samples of L2 peer interaction were examined. Fluency measures corresponded to the rated dimensions. In a mixed-methods analysis, correlational analyses across the ratings and between the ratings and fluency measures were performed. The raters’ comments were analyzed qualitatively. The results demonstrated correlations between the ratings and measures of fluency for individual and interactional fluency, but not for strategic competence. The mean length of turn pauses correlated strongly with interactional fluency ratings. The raters’ comments revealed a multifaceted conceptualization of interactional fluency and strategic competence. The results have implications for L2 fluency measurement and assessment.
