In today's digital era, smartphones have become an integral part of students' daily lives. In particular, the increasing use of smartphones among primary-level students has raised signif- -icant concerns regarding their ultimate impact on formal and informal learning activities. Against this background, the present study primarily investigates the multifaceted impact of smartphone usage on the learning activities of Grade 05 students. The study was conducted based on Tamil-medium schools located in the Beruwala Educational Zone. A quantitative research approach was successfully employed, and primary data were comprehensively collected from students, parents, and teachers using structured, closed-ended questionnaires. The collected data were meticulously analyzed using descriptive and inferential statistical methods via SPSS software. The empirical findings of the study reveal that the extent of smartphone usage time, the specific purpose of use, the nature of the accessed content, parental and teacher supervision levels, and smartphones can be successfully transformed into highly effective learning tools. The empirical findings of this study provide critical practical insights for educators, parents, and educational policymakers in developing holistic strategies to enhance students' learning outcomes within the modern digital age.
