The present study was intended to examine the effects of 1) fields of study (arts, business and science-oriented); and 2) language-learning experiences (whether limited or non-limited to formal classroom instructions) on the use of VLSs among Thai tertiary-level students. The participants were 905 Thai EFL students studying in the Northeast of Thailand. The VLS questionnaire was employed for data collection. Descriptive statistics, an Analysis of Variance (ANOVA) and the chi-square tests were performed for data analysis. The results revealed that fields of study and prior language-learning experiences affected the students’ overall VLS use, use of VLSs by the category and the individual strategy levels. The variation patterns of students’ VLS use were found in relation to the two variables.
