The rapid advancement of educational technologies has significantly transformed teaching and learning activities in higher learning institutions across the world. Most universities currently rely on internet-based learning management systems and cloud communication platforms to support lecture delivery, assignment submission, classroom interaction, online assessments, and academic communication between lecturers and students. However, many developing countries continue to experience challenges associated with unstable internet connectivity, high bandwidth costs, poor network infrastructure, and limited accessibility to reliable online learning systems. These challenges negatively affect real- time lecture delivery, student engagement, classroom communication, and accessibility of learning materials during academic activities.
This study presents the design and implementation of an Offline Interactive Classroom System for Real-Time Lecture Delivery and Student Engagement intended to support efficient classroom communication and learning activities without requiring internet connectivity. The proposed system uses Local Area Network (LAN) technology together with a local server architecture to allow lecturers and students to communicate, share lecture materials, conduct quizzes, manage attendance, submit assignments, and exchange classroom information in real time within an offline environment. The system was developed using React.js for frontend development, Node.js and Express.js for backend services, SQLite/ MySQL database for local data management, and XAMPP as the local hosting server. The developed system successfully improved classroom interaction, reduced internet dependency, enhanced learning accessibility, and increased student participation during learning sessions. The findings demonstrate that the proposed system provides a reliable, low- cost, and efficient offline classroom communication solution suitable for universities and colleges with limited internet infrastructure.
