Abstract

Purpose - This study examines the relationship between vocabulary mastery and self-confidence among students in an intensive Arabic learning program at Markaz Arabiyah Pare. Speaking performance was not measured; no claim is made regarding either variable's effect on oral production outcomes.

Design/methodology/approach - A quantitative correlational design was employed with 25 students from the I’dad Awal A class selected through purposive sampling. Two instruments were used: a vocabulary mastery test (10 valid items; α = 0.828) and a self-confidence questionnaire (16 valid statements; α = 0.791), both validated through expert review and SPSS-based item analysis. Shapiro–Wilk normality testing led to the use of Spearman’s rho for correlation analysis.

Findings/results – A statistically significant moderate positive correlation was found between vocabulary mastery and self-confidence (rₛ = 0.444, p = 0.026, r² = 0.197). Descriptive statistics revealed a wide vocabulary score distribution (M = 50.00, SD = 30.14, Mdn = 40, IQR = 60) against a considerably narrower self-confidence distribution (M = 56.52, SD = 6.10, Mdn = 56, IQR = 7). Vocabulary mastery accounted for approximately 19.7% of the variance in self-confidence scores.

Originality/value - This study is among the first to directly examine the relationship between linguistic readiness (vocabulary mastery) and affective readiness (self-confidence) within an intensive Arabic learning institution in Indonesia. Rather than treating the two variables as independent predictors of speaking performance, it investigates their direct interrelationship—a question underexplored in Arabic language acquisition research.
