ABSTRACT

Electronic marking is a digital marking system which allows exam scripts markers to mark exam responses which have been scanned and uploaded as digital images, or online assessment responses on a computer screen, rather than on paper. The aim of the study is to Design and Implement an Electronic Marking of Exam Scripts. In achieving this aim, the following specific objectives were laid out as follows to design and develop an application software that will eliminate the manual marking process of exam script processing as it has to be done by hand and preparing results to enable them do their research work. The motivation that led to the implementation of the proposed system is as a result of the manual methods of marking exam script which are enormous and the manual marking slows the process of exam script processing as it has to be done by hand. The methodology adopted in this study is the structured system analysis and design methodology (SSADM) which is a technical approach for analyzing and designing an application or system by applying object throughout the software development process. The programming language used is HTML, CSS, JAVASCRIPT, PHP, SQL and JQUERY. The reason why web programming languages was used is because, it is platform independent and it is a web based application. This project will be of benefit to Lecturers and Exam script markers. The expected result is an Electronic Marking of Exam Scripts system that will mark exam script automatically and grade the score based on student answers corresponding to the correct one trained into the system data set.


Design and Implementation of Electronic Marking of Exam Scripts

CHAPTER ONE

1.1 Introduction

Electronic marking (E-marking), also known as onscreen marking or digital marking, is the use of digital technology in the education or accreditation sector specifically designed for marking or grading an exam or assessment. E-marking applications allow markers to mark exam responses which have been scanned and uploaded as digital images, or online assessment responses on a computer screen, rather than on paper. It is the opposite of traditional ‘pen and paper’ marking, and can be executed via a local application, or via a browser-based application delivered over the Internet. There are no restrictions on the types of tests that can be marked using e-marking. E-marking is widely applied amongst high stakes examinations throughout the world, with two thirds of marking completed in this way in the Nigeria. It is also used to assess other types of qualifications such as exams for accountants, as seen by its use by the Association of Chartered Certified Accountants.

As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.


1.2 Background of Study

Manual Examination marking System is replete with several problems. A cursory glance at Manual Examination marking Administration System reveals cases of partiality, favoritism and injustice in the marking process by the staff or the class instructor, also, outside the above the person could be under physical or emotional trauma that could result in failure to carry out the required duty in safe state. The manual Examination marking System also has been discovered to have more issues, as it gives room for written examination to be updated by the student or lecturer when bribe has taken place, exchange of results marks and many more.

In furtherance, during manual computation of results, errors may arise due to “omission” or “commission”. There are also cases of missing examination scripts during marking. There is also a problem of time wasting, among others.

This research suggests that if an efficient and effective electronic examination script marking system is developed, where examinations will be taken online, and results computed and released immediately, as well as stored in a central database for documentation and future planning and evaluation purposes, there shall be relative balance and harmony within the University System. The staff will take the advantage of time that would have been spent on marking examination and preparing results to enable them do their research work. This will also cause the unserious students to be committed to their studies.

The errors associated with the existing manual method of examination marking process of students’ exams in most universities in Nigeria, make it not only desirable but imperative that computerized approach be used to the full in measuring students’ academic progress. The manual methods being employed suffer a number of set-back. They make the process to be time-consuming and prone to errors even as they lead to late publication of exam marked results. Worst still, sometimes wrong scores are calculated for and entered for the. Consequently, the cumulative errors being generated are ultimately linked to awarding of erroneous class of degree. Some students could end up with undeserved good classes of degree, while others could be unfairly victimized, bringing about frustration. In this case, the image of the department(s) concerned and the whole University alike could become tarnished. The problem, therefore, that arises is to find a method of marking examination scripts that would be sufficiently accurate and reasonably timely.


1.3 Statement of Problem

The problems posed by manual methods of marking exam script are enormous. Manual marking slows the process of exam script processing as it has to be done by hand. This has result to procrastinating the results of academic students hence, delay in leaving in student time of graduation and possible for the National Youth Service when they ought to have gone. This problem has dominated the academic.

To arrest this problem, there is a need to step up the use of electronic marking system that is accurate, error free, and that can if possible run on the web (using real time) in order to give students access to their score as at when needed. This will also help reduce the time wait for exam script score.


1.4 Aim and Objectives of the Study

The aim of the study is to Design and Implement an Electronic Marking of Exam Scripts. In achieving this aim, the following specific objectives were laid out as follows to design and develop an application software that will:

  1. Mark exam script automatically and grade the score based on student answers corresponding to the correct one trained into the system data set.
  2. Find a sufficiently fast and accurate method of carrying out this marking process of exam scripts
  3. Eliminate the manual marking process of exam script processing as it has to be done by hand.
  4. Detect missing examination scripts during marking and notify the appropriate course authority.
  5. Take the advantage of time that would have been spent on marking examination and preparing results to enable them do their research work.

1.5 Significance of Study

This research relevance will be an efficient and effective electronic examination script marking system developed, where examinations will be taken online, and results computed and released immediately, as well as stored in a central database for documentation and future planning and evaluation purposes, there shall be relative balance and harmony within the University System.

This study will be of immense benefit to other researchers who intend to know more on this study and can also be used by non-researchers to build more on their research work. This study contributes to knowledge and could serve as a guide for other study.


1.6 Scope of Study

The study focuses on the Design and Implementation of Electronic Marking of Exam Scripts using University of Nigeria (UNN) as a case study.


1.7 Limitations of the Study

During the course of this study, many things militated against its completion, some of which are:

  1. Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
  2. Research material: availability of research material is a major setback to the scope of the study.
  3. Frequent power failure: This made the researcher append more money on fuel to ensure sustainable power.
  4. Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).

1.8 Definition of Terms
