Abstract

Computer-based Test (CBT) has over the years become an acceptable and ideal method of student’s assessment in Nigeria, and the major idea is to eliminate examination malpractices, deal with security challenges, cost reduction and improve the results grading system as well as other sundry issues. This study examined the perception of students and lecturers towards the use of adaptive technologies in introducing text-to-speech recognition system, face
identification authentication and security level of CBT in six Nigerian Universities which constitute a major gap in the literature. A questionnaire survey was adopted using random sampling technique to analyze 498 samples collected from 201 males and 297 females. The results revealed that adaptive technologies which includes text-to-speech (read aloud) and face-ID authentication can help improve CBT, and greater percentage of the respondents
strongly agreed that examination malpractices can be mitigated with a mean of 4.84 and 0.67 respectively. Overall, the average score of all the measure used shows an average of 89.30% accuracy, indicative of upgrade for the future prospect. Finally, when tested, the study obtained 90.46% scalability, 88.37% flexibility, 87.98% reliability, 89.15% user-friendliness and 87.98% reliability respectively.
