Computer-Based Test Cbt System For University Academic Enterprise Examination

Abstract As flexible and online learning mediated by ICT becomes more pervasive there is a growing need for educators to consider modes of assessment using similar tools. Computer Based Test CBT is an effective solution for mass education evaluation. Though a variety of e-assessment approaches and systems have been developed in recent times yet lack of flexible timing functionality to automatically log-off candidates upon expiration of allotted time result integrity comprise stand-alone deployment lack of flexibility robustness and scalability as well as human error are major limitations of the existing platforms. In this paper a web-based online examination system is developed to address these aforementioned drawbacks. The system is designed to facilitate the examination processes and manage challenges surrounding the conduct of examination auto-submission auto-marking and examination result report generation. The conceptual design including the Data Flow Diagram DFD the Use Cases and the Entity-Relationship Model ERM for the system developed is also presented. The programming tools used for the front-end development of the system are Hypertext Markup Language HTML and Microsoft Visual Studio 2012 integrated development environment while Microsoft SQL Server 2008 is used as the database backend. The CBT system was evaluated at the Federal University Oye-Ekiti Ekiti State prometric centre. Performance assessment was carried out by two-hundred and fifty 250 volunteer users of the CBT system and the average performance scoring indicate that the system scores high in terms of reliability robustness and flexibility with easy to use graphical user interface. The volunteers comprise of software developers students lecturers and network engineers. The test proved the validity of using this web-based CBT system to evaluate a large mass of students in various institutions of learning across the globe.
