1.1 Introduction
An examination is a systematic process of evaluating a learner's knowledge, skills, and competence in a particular subject area. According to Olatunji (2019), examination serves as an assessment tool designed to measure learning outcomes and ensure that educational objectives are achieved. Grading, on the other hand, is the interpretation of examination scores into symbols or letters that reflect the academic performance of students. Traditionally, examination marking and grading have been handled manually by teachers and examiners, but this method is often characterized by stress, time consumption, errors, and subjectivity (Adebayo et al., 2018).
The advent of technology has transformed the way educational institutions manage examinations. Automated examination marking and grading systems refer to computer-based solutions designed to evaluate, score, and assign grades to students' examination responses with minimal human intervention. These systems are developed to enhance accuracy, efficiency, and fairness in the assessment process (Nwankwo, 2020).
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, Limitation of the study and Definition of technical terms.
1.2 Background of Study
Examinations remain a critical tool in evaluating students' knowledge, skills, and competencies in formal education systems. According to Olatunji (2019), examinations provide a structured method of assessing learning outcomes and ensuring that educational objectives are met. Adebayo and Abdulhamid (2018) reported that manual examination marking and grading, which is still widely practiced in many institutions, is often plagued by challenges such as delays, human errors, inconsistency, and examiner fatigue. These challenges not only affect the credibility of the assessment process but also reduce students' confidence in the fairness of their academic evaluation (Adebayo and Abdulhamid, 2018).
Okeke (2019) asserted that the continuous rise in student enrollment in higher institutions has placed immense pressure on examiners, making manual grading increasingly inefficient. The manual process involves tedious tasks such as script collation, score recording, and grade computation, all of which are prone to mistakes. Furthermore, Nwankwo (2020) stated that such methods create room for bias and subjectivity, as examiners' judgments may be influenced by fatigue or other external factors (Nwankwo, 2020).
Ogunlade and Alade (2021) affirmed that automated examination marking and grading systems have the potential to provide more efficient, accurate, and unbiased assessments. They contended that such systems also facilitate faster processing of results, eliminate redundancy, and promote transparency in the educational system. On the other hand, existing automated systems are sometimes limited in scope, as many are restricted to objective question types like multiple-choice questions and struggle to adapt to more complex question formats such as short answers or essays (Ogunlade and Alade, 2021).
Audu (2017) stated that security remains another pressing issue in examination processes. Manual scripts are vulnerable to loss, manipulation, or destruction, while poorly designed automated systems may be susceptible to unauthorized access or data breaches. These problems highlight the urgent need for a more secure and improved system that safeguards examination data, maintains confidentiality, and upholds trust in academic assessments.
The importance of an improved automated examination system cannot be overstated. In a rapidly growing educational landscape, the volume of students has increased significantly, thereby putting more pressure on lecturers and institutions to process results in a timely and accurate manner. Delays or errors in grading may negatively affect students' academic progression, scholarship opportunities, and even their morale (Okeke, 2019).
The proposed study on the design and implementation of an improved automated examination marking and grading system aims to provide a solution that ensures accuracy, promotes fairness, reduces workload, enhances efficiency, and integrates seamlessly with existing institutional processes. This study is set against the backdrop of the need to design and implement an improved automated examination marking and grading system that addresses inefficiencies, enhances security, ensures fairness, and promotes the integrity of academic assessments in line with technological advancements.
1.3 Statement of Problem
Investigation revealed the problems identified in existing examination marking and grading systems include:
- In the existing system, exam scripts are often marked manually by lecturers or examiners. This creates room for human errors such as miscalculation of scores, and inconsistencies in awarding marks, which reduces the accuracy and reliability of the grading process.
- Manual marking of examination scripts requires a considerable amount of time, especially when handling a large population of students.
- The existing system is prone to examiner subjectivity, favoritism, or fatigue, which can influence how marks are awarded.
- Traditional marking and grading methods rely heavily on paper-based systems. Over time, student records may be misplaced, damaged, or poorly stored, making it difficult to retrieve or verify results when needed.
- The paper-based system is vulnerable to malpractice, such as unauthorized alteration of scripts, leakage of examination scores, and manipulation of student results.
- As student enrollment continues to increase, the manual system struggles to keep up with the workload. The existing method lacks scalability, leading to inefficiency in managing examinations across large institutions.
1.4 Aim and Objectives of the Study
The aim of the study is to develop and implement an improved automated examination marking and grading system that ensures accuracy, transparency, and efficiency in students' assessment. In achieving this aim, the following specific objectives were laid out as follows:
- To create an efficient and reliable platform that automates the process of marking examination scripts with high accuracy and reduced human errors.
- To develop a grading system that ensures fairness, consistency, and transparency in student performance evaluation.
- To design a user-friendly interface that allows examiners, administrators, and students to easily interact with the system for marking, result checking, and record management.
- To implement a secure database system for storing, retrieving, and managing students' examination records without the risk of data loss or manipulation.
- To create and implement a scalable solution capable of handling large student populations efficiently, reducing delays in result processing and dissemination.
1.5 Significance of Study
It is believed that at the completion of the study, the proposed system will enhance the efficiency of examination marking and grading processes. The system will also reduce human errors, minimize subjectivity, and promote fairness in assessment.
Additionally, students will benefit greatly from this system as it will facilitate timely release of examination results. It will also promote efficiency in the management of examination records, making it easier to store, retrieve, and secure students' academic data.
Furthermore, this research will provide timely results for students, improve institutional credibility, and secure examination data against manipulation or loss. The system will also promote fairness and transparency, as grading will be based on standardized procedures, thereby eliminating biases that may arise from manual evaluation.
Lastly, the study will serve as a valuable resource for researchers, software developers, and policymakers interested in advancing technology-driven solutions in the education sector.
1.6 Scope of Study
The scope of this research is focused on the design and implementation of an improved automated examination marking and grading system using University of Ibadan, Oyo State, Nigeria 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:
- 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.
- 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).
