WhatsApp as a Knowledge-Sharing Platform: Insights from Postgraduate Students at the University of Kelaniya, Sri Lanka

Abstract

This study investigates the use of WhatsApp for knowledge sharing among postgraduate students at the Library of the Postgraduate Institute of Archaeology (PGIAR), University of Kelaniya, Sri Lanka. The focus is on WhatsApp groups as mobile learning platforms that facilitate knowledge exchange, particularly in relation to students’ academic activities. The research specifically targets postgraduate students from the 2022/23 academic year, using a case study approach. Data were collected through a multiple-questionnaire method distributed via WhatsApp groups for the PG Diploma and Master’s programs. Of the 62 students in these groups, 49 participated, yielding a 79% response rate. The findings suggest that WhatsApp serves as an effective tool for sharing academic resources such as PDFs, videos, audios, and text, with students frequently sharing research insights and study materials. Key motivators for its use included the platform’s ease of use, quick feedback mechanisms, extensive reach, and availability. However, challenges were noted, such as non-compliance with group guidelines, which hindered optimal knowledge sharing. Additionally, issues like device dependence, connectivity problems, and reduced community engagement were observed, affecting overall interaction quality. Despite these challenges, WhatsApp was recognized as a valuable tool for mobile learning and knowledge sharing. The study highlights the potential of mobile technologies to enhance blended learning environments, demonstrating that WhatsApp can improve student engagement, collaboration, and access to educational resources. Students expressed positive attitudes toward WhatsApp, appreciating its ability to promote teamwork and support academic communication. While distractions, privacy concerns, and the informal nature of the platform may influence learning, the research underscores WhatsApp’s role as a flexible and efficient tool for postgraduate students’ academic development.
