STUDENT COLLABORATION "STUDY HUB" PORTAL

The Student Collaboration "Study Hub" Portal is a web-based platform designed to support peer learning and academic collaboration among university students. Traditional academic environments often lack dedicated digital infrastructure for informal peer-to-peer learning, group study coordination, and real-time collaborative knowledge exchange. This paper presents the design, architecture, and implementation of the Study Hub Portal, a full-stack web application developed using React.js for the frontend and MongoDB for backend data persistence, connected via RESTful APIs. The system enables students to create and join study groups, share annotated notes, initiate threaded academic discussions, and collaboratively manage assignments within a structured digital workspace. A role-based access control (RBAC) model governs user privileges, while a modular microservice-inspired architecture ensures scalability and maintainability. Usability evaluations conducted with fifty-two student participants demonstrated a System Usability Scale (SUS) score of 82.4, indicating excellent usability. The portal achieved sub-300 ms average API response times under concurrent load, confirming its suitability for real-world academic deployment. By centralizing communication and resource sharing, the Study Hub Portal fosters collaborative learning, promotes academic engagement, and measurably improves students' subject comprehension.
