Postgraduate Students’ Perceptions of Online Learning Effectiveness and Efficiency in Malaysia: A TAM and Constructivist Perspective

HRMARS - The rapid digitalization of higher education, accelerated by the COVID-19 pandemic, has positioned online learning as a primary mode of instructional delivery in Malaysian universities. While this transition has ensured academic continuity and flexibility, concerns remain regarding its overall instructional quality and operational value, particularly among postgraduate students who frequently balance academic, professional, and personal responsibilities. However, limited studies have simultaneously examined postgraduate students’ evaluations of both instructional effectiveness and learning efficiency within a structured theoretical framework. Guided by the Technology Acceptance Model (TAM) and Constructivist Learning Theory, this study investigates postgraduate students’ evaluations of online learning at UNITAR International University. A quantitative survey design was employed involving 100 postgraduate students across fully online, hybrid, and physical study modes. Data were analysed using descriptive statistics, independent samples t-tests, and one-way ANOVA. The findings indicate that respondents generally hold positive evaluations of online learning, with efficiency (M = 4.33) rated higher than instructional effectiveness (M = 4.01). Flexibility, time savings, and cost reduction emerged as dominant contributors to efficiency, while structured course design and clarity of instructional materials supported learning effectiveness. Inferential analyses revealed no statistically significant differences across gender, age, or mode of study, suggesting consistency in perceptions across demographic groups. The study underscores the importance of structured instructional design, stable digital infrastructure, and sustained teaching presence in enhancing postgraduate online learning experiences. These findings contribute to theoretical discourse by integrating technology acceptance and constructivist perspectives and provide practical implications for institutional policy and pedagogical enhancement in Malaysian higher education.
