Computer-based
exams (CBE) have several important advantages compared to traditional
paper-based exams (PBE) such as efficiency, immediate scoring, and feedback in
the case of multiple-choice question exams. Furthermore, CBE allows more
innovative and authentic assessments due to more advanced technological
capacities.
However,
there are also drawbacks when administering CBE such as the additional need for
adequate facilities, test security, backup procedures in case of technological
failure, and time for staff and students to get acquainted with new technology.
It is generally recognized that examinations determine the extent to which
educational objectives have been achieved as well as the extent to which
educational institutions have served the needs of the community and society
(Shah, 2002). Examinations are not limited to measuring educational or societal
objectives and needs but are incorporated into a way of coping with the
educational system (Havens, 2002). Rehmani (2003) briefly described
examinations as playing a significant role in determining what goes on in the
classroom in terms of what, and how teachers teach and students learn and can
have an impact on both teaching and learning. Wikipedia describe examinations
as alternative terms of assessment and defined it as: 'test or an examination
(or exam) is an assessment indeed to measure a test-takers knowledge, skill,
aptitude, physical, fitness or classification in many other topics
1.2 Problem Statement
The
challenges faced with the Pencil-Paper examination system or Paper-based test
in the institution and departments offering General courses (GNS) and courses
with the largest population of students taking it are overwhelming, they
include but are not limited to exam malpractice, inaccuracy in marking, delay
in marking and processing of results.
1.3 Aim and Objectives
This
project is aimed at developing a computer-based student examination system for
General courses which are taken by the largest number of student population.
The
objectives of this project are:
· To
provide a friendly, easy-to-use examination platform for students.
· To
develop a Computer Based Examination system with enhanced security features to
avoid examination malpractice.
· Reduce
the level of examination malpractices and improve the credibility of the
examinations via multifactor authentication and randomization of exam
questions.
· Real-time
processing of results
·
The system will
automatically generate total scores of the examinations.
The
scope of this project is to develop a computer-based examination system using
Jigawa State polytechnic as the case study.
The
system will only cover General courses (GNS)which the largest number of
students population offering in the institution e.g., English, citizenship,
entrepreneurship, introduction to computer, etc.
