THE CORRELATION BETWEEN STUDENTS’ VOCABULARY MASTERY AND THEIR SPEAKING FLUENCY

Abstract

This research investigates the relationship between vocabulary mastery and speaking ability among students at SMKN 15 Samarinda. Vocabulary plays a crucial role in English language learning, impacting speaking fluency and communication skills. The study adopts a quantitative approach with a correlational design, using the Vocabulary Levels Test (VLT) and a Speaking Test adapted from IELTS to measure these variables. Data from 29 students were analyzed using Pearson Product-moment Correlation in IBM SPSS Statistics 27. The findings reveal a significance value of 0.511, indicating no statistically significant correlation between vocabulary mastery and speaking fluency. This challenges the assumption that a larger vocabulary directly enhances speaking skills, suggesting the presence of other influential factors. The study contributes theoretically by providing insights into language learning dynamics and practically by guiding educators on effective teaching strategies. Further research could explore additional variables impacting speaking proficiency beyond vocabulary mastery.
