Background: The widespread adoption of WhatsApp for academic purposes in higher education institutions across sub-Saharan Africa has outpaced institutional policy frameworks, creating both opportunities for enhanced communication and challenges related to equity, professionalism, and pedagogical effectiveness. This study investigates the use of WhatsApp for academic engagement among undergraduate students and lecturers at the University of Kabianga (UoK), a Kenyan public university, to understand current practices, perceived benefits and barriers, and implications for formal institutional integration. 

Research Questions:  

This study investigates the extent to which WhatsApp enhances student engagement and collaborative learning, examines how digital divide challenges (internet affordability, device access, digital literacy) impact its inclusivity across socioeconomic groups, and explores stakeholder perceptions of the benefits, barriers, and desirability of formal institutional integration at the University of Kabianga. 

Methodology 

Grounded in a pragmatist research paradigm, the study employed a sequential explanatory mixed-methods design. This paper reports findings from the quantitative phase involving 299 undergraduate students and 25 lecturers who completed structured questionnaires adapted from established scales. The survey captured demographic information, usage patterns, perceived benefits and challenges (measured on 5-point Likert scales), engagement behaviours, and recommendations for formal guidelines. Data were analysed using descriptive statistics (frequencies, percentages, means, standard deviations). The study is theoretically framed by three complementary lenses: the Community of Inquiry (CoI) framework for analysing educational interaction, Digital Divide Theory (three-level model) for examining equity dimensions, and the Unified Theory of Acceptance and Use of Technology (UTAUT) for understanding technology adoption determinants. 

Key Findings 

Students 

This study reveals that WhatsApp is deeply embedded in student academic life, with near-universal adoption (94.6%) and high-frequency engagement (66.9% use it multiple times daily). Students perceive the platform as highly effective for learning, particularly for peer support (4.45), collaboration (4.44), and resource sharing (4.46). Engagement is robust and peer-driven, with 70.9% asking academic questions and 77.9% sharing resources. 

However, significant equity challenges persist. While smartphone access is high (96.7%), data costs burden over half of students (54.5%), and reliable internet remains inconsistent (mean 3.91). Information management issues, notification fatigue (34.4%), overload (32.8%), and difficulty finding information (27.1%), further complicate effective use. 

Critically, two-thirds of students (66.2%) support formal integration, demanding institutional guidelines (mean 4.25), particularly for academic-purpose-only use (40.9%), to bring structure and legitimacy to their current informal practices. 

Lecturers 

WhatsApp use is nearly universal among lecturers, with 96% communicating with colleagues and 92% with student groups. However, usage remains predominantly transactional, focused on announcements (92%), material sharing (84%), and answering questions (80%). Deeper pedagogical activities like facilitating discussions (56%) and providing feedback (40%) are less common. 

Lecturers value WhatsApp for administrative efficiency (mean 4.36) and informal interaction (mean 4.25). Their primary concern is the absence of clear institutional policy (mean 4.41), followed by expectations of 24/7 availability (mean 3.96) and blurred professional boundaries (mean 3.17). 

An unanticipated finding reveals WhatsApp’s vital role in faculty professional community building, with exceptionally high ratings for collegial problem-solving (mean 4.54), resource sharing (mean 4.44), and departmental coordination (mean 4.42). Notably, 80% report WhatsApp enhances their sense of professional community, and 84% support formal guidelines, feeling prepared for professional integration. 

Conclusions and Implications 

WhatsApp functions as the central nervous system of academic life at UoK, driving peer-supported learning and faculty collegiality while operating in an institutional policy vacuum. Both students and lecturers overwhelmingly support formal integration with clear guidelines addressing communication boundaries, data protection, information management, and equity safeguards. The study contributes empirical evidence from a Kenyan context, addresses the geographical imbalance in educational technology research, and reveals WhatsApp’s dual function in supporting both student engagement and faculty professional community. Findings underscore that effective educational technology policy must balance accessibility with structure, innovation with professionalism, and efficiency with equity, a complex but essential undertaking for higher education institutions navigating digital transformation in the Global South.
