Abstract
The current study investigates how second language (L2) listening comprehension is associated with three dimensions of L2 vocabulary knowledge: size, depth, and fluency. Vocabulary knowledge tests administered to 290 participants measured L2 auditory vocabulary size, depth, and fluency. Afterward, participants took an International English Language Testing System (IELTS) listening test that measured L2 listening comprehension. Using a structural equation modeling technique, we found that all three dimensions of vocabulary knowledge are significant predictors of L2 listening comprehension. Size of auditory vocabulary in the L2 has the strongest predictive power over L2 listening comprehension. The results of the current study offer useful pedagogical implications for improving L2 listening comprehension.
Résumé
La présente étude examine comment la compréhension orale de la deuxième langue (L2) est associée à trois dimensions de la connaissance du vocabulaire de la L2 : la taille, la profondeur et la fluidité. Des tests de connaissance du vocabulaire mesurant la taille, la profondeur et la fluence du vocabulaire auditif de la L2 ont été administrés à 290 participants. Ensuite, les participants ont passé un test d’écoute International English Language Testing System (IELTS) qui mesure la compréhension à l’écoute de la L2. En utilisant une technique de modélisation par équation structurelle, nous avons constaté que les trois dimensions de la connaissance du vocabulaire sont des prédicteurs significatifs de la compréhension orale de la L2. La taille du vocabulaire auditif L2 a la plus forte puissance prédictive sur la compréhension orale de la L2. Les résultats de la présente étude offrent des implications pédagogiques utiles pour améliorer la compréhension orale L2.
