Description

ABSTRACT

This work is concerned with computer based examination system. It focused on trends in online computer based examination and carried out a critical review of current computer based test system employ in Cisco Training Centre of Prof. Iya Abubakar CRC. An alternative system to provide solutions to the current challenges identified in the existing system was then proposed. The system was designed using the object OOAD methodology and implemented using rapid PHP IDE on a Windows 10 system, using PHP, HTML, CSS and MySQL technologies and Apache server as the application server with multifactor authentication.

CHAPTER ONE: INTRODUCTION

 

             Background of Study

 

Computer-based exams (CBE) have a number of 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 allow more innovative and authentic assessments due to more advanced technological capacities. Examples are the use of video clips and slide shows to assess medical students in surgery or the use of computer based case simulations to assess social skills. However, there are also drawbacks when administering CBE such as the additional need for adequate facilities, test-security, back-up 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 community and society (Shah, 2002). Examinations are not limited to measure educational or societal objectives and needs but incorporated in a way of coping with the educational system (Havens, 2002). Rehmani (2003) briefly described that ‘examinations play 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 impact on both teaching and learning’. Wikipedia used test or 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’.

The Cisco Networking Academy, Professor Iya Abubakar Community Resource Centre have been widely recognised as the best in the North-Eastern Region of Nigeria where students enrolled for Training and Certification courses ranging from IT Essential to CCNA Routing and Switching (CCNA 1,2,3 & 4). One key feature associated with International Certification/

 

Training Courses such as the CCNA is the use of Computer Based Exam as a platform for testing the knowledge that students have acquired at the end of the theoretical and Hands on Skills sessions (i.e. end of course exam). Also, the use of Online examinations in the CCNA curriculum enable student to test the instant knowledge that they have acquired at the end of each chapter, which is usually done at the end of each week since a CCNA training module comprises of 9 – 11 chapters and runs for a duration of 12 weeks.

The Cisco exams have changed several times. In 2013, Cisco announced an update to its certification program that “aligns certification and training curricula with evolving industry job roles” (Cisco Technology News Site, 2013). Bobiles (2016) reviewed that ‘there are now several different types of Cisco-Certified Network Associate, with “CCNA Routing and Switching” being closest to the original CCNA focus; other types of CCNA focus on security, collaboration, data centres, service providers, video, voice, and wireless’.

             Statement of Problem

 

The challenges faced with International Training Certifications is that the organizations that issues this certificates adopts a medium whereby its various Training Centres spread across the globe, subjects their trainees to a centralized online examinations platform; in which the performances of the trainees in these centres can be tracked and monitored. For that reason, the Training Centres are mandated toprovide internet access to the students which lead to huge budget for data subscriptions.

It has been observedthat these Regulatory Bodies,do carry routinemaintenance on their online examination platform which may sometimes lead to up twelve (12) hours downtime; prompting the Training centres to reschedule their examinations to a later date leading to the discouragement of students who have extensively prepared for the exam.Also, most of

 

theseOnlineTraining Exams contain recycled questions that have been made available in various websites – prompting to a high level of malpractices.

             Aim and Objectives of Study

 

The aim of this project is to design and implementa computer based examination system with multi-factor authentication andmessage notification features.

Objectives of the study

 

1. Provide a friendly, easyto use examination platform for

 

2. Reduce the level of examination malpractices and improve the credibility of the examinationsvia multifactor authentication and randomization of exams
3. Provide a real-time processing of results with notifications via SMS and E-Mail at the end of the examination

             Scope of the Study

 

The study covered the design and implementation of acomputer based examination system with multifactor authentication and message notification features using Cisco Networking Academy, Prof. Iya Abubakar Community Resource Centre Bauchi as the case study. This system would enable the Training Centre to administer customized questions during examinations and provide access to offline materials.

The limitations of the system to be designed are as follows

 

1. This Examination system is designed for Educational Institutions (like schools, universities and training centres)
2. The system supports only multiple choice

 

3. The system would enrol users using the internet before they can use

 

4. The subscribers of MTN and Etisalat Network would not be able to enrolled in the system to the Do Not Disturb (DND) service incorporated by

 

             Justification of Study

 

Due to the challenges, which have persisted in the Cisco Networking Academy online examination is that is been done in the Cisco Official website, the justification for this work is as follows:

1. The online examination platform could not handle the problem of exam malpractice as the questions are found in various website due to inability of the International Training Organization to recycle their questions
2. To save cost of constant purchase of internet data subscription and also save time and human labour of strolling around the exams to fixed problems that arise due to internet
3. To provide students with a copy of their results at the end of exams either via SMS or E-mail
4. To provide students with relevant study materials and resource without the need of going to the internet to search and download

             Definition of Terms

 

This defines terminology specific to the problem domain, explaining terms, which may be unfamiliar to the reader of the use-case descriptions or other project documents. The following are the definition of terms used in this project work including acronyms and their meaning:

1. Examination: A test to show a person’s progress, knowledge or ability, it comprises of some question and multiple choices
2. Student: A person who has an account on the computer based online examination
3. Administrator: A person who manages the operation of the computer based

 

4. Guest: A person who has not registered an account in the computer based examination

 

5. Profile: All the information of candidate such as name, course, grades of all examined computer based
6. Question: A problem that has a number of choices and only one correct

 

7. CBT: Computer Based Testing, it is a platform that uses computers to test or assess (examine)
8. PPT: Paper Pencil Test, it is also a platform that uses paper and pencil to test or assess (examine)

CCNA: Cisco Certified Networking Associate, this an International Certification Course that is conducted by Cisco Networking Inc., and it covers the discipline of Computer and Mobile Networking.
