Abstract: This study investigates the utilization patterns, perceptions, and motivating factors associated with the use of social media as a tool for vocabulary learning among first-year undergraduate students across diverse academic majors. Data were collected from 152 participants representing healthcare, technical, business, and social sciences majors through a survey-based approach. The findings reveal that a significant proportion of first-year students across all majors report frequent usage of social media platforms for vocabulary learning, with variations observed in the perceived effectiveness of these platforms. Convenience and accessibility emerged as primary motivators, followed by factors such as engagement, variety of resources, real-life context, and motivation/accountability.
