Improving Quality of Education by Evaluating the Capacity of Lecturers Using a Web Based System

Evaluating the capacity of lecturer is the key to improve quality of education by improving lecturer capacity in higher education institution. Lecturer’s capacity has been evaluated using different parameters in Assosa University, Ethiopia. Mandatorily, lecturers are evaluated using printed check list. For the last few years we observed that, the lecturer efficiency score is found on the shelf and not checked by anyone to know the gaps and to establish fol-low-up system. The use of intranet based web system is better to use lecturer’s efficiency result to monitor their performance and to establish follow-up mechanism. In this study, a prototype of web based yearbook efficiency management system for evaluating and monitoring the performance of lecturers was designed and developed. The evaluation process in the system was presented according to the university evaluation format. The output gener-ated by the proposed system can be used by lecturers, HoD, HRM and academic managers to monitor teaching performance.


Background
Today, advancement of technologies changes almost all our day to day activities all over the world. This is because technology is considerably changing the entire way of human life and their activities. Educational system is the most relatively benefited systems from the technologies which gradually change the techniques of teaching, learning and evaluation process and the key to improving education [1] [2]. With this, in countries educational system, the educators have a lion role to produce academically top ranked, skillful, innovative and disciplined citizen. In this regard in addition to other factors, higher education institutions' lecturers are the key for the success of students [3] [4] [5]. Without question, the performance of lecturers has greater impact on quality of education, student's academic skillfulness and innovativeness. Therefore, the performance of lecturers' must be continuously evaluated and improved by establishing follow up system [6] [7].
In Ethiopian higher education institutions, lecturers are evaluated by students, colleagues and head of departments (HoD). The evaluation is conducted at the end of each semester and the lecturers have semester efficiency as well as yearly efficiency which is average efficiency of the two semesters.
In this technological era, there must be a way of evaluating lecturers using simple process. In this study, intranet based follow up mechanism is proposed.
In this way, the performance of lecturers' using web based system is recorded, evaluated and submitted to the department. Using the proposed system, the lecturer's evaluation result is used not only to get just a score as a measure of efficiency but also to improve performance. Also it saves staff time and energy as well as university resources because the processes of manually preparing, packaging, distributing, collecting, analyzing and reporting results are replaced by the proposed system. In the following sections problem of statement, objectives, methods and materials, results and discussions as well as conclusions are discussed.

Statement of the Problem
At present, all Universities in Ethiopia uses paper based evaluation system to measure lecturers' efficiency. The process of this manual system requires high labor, significant timing and resources from preparation to reporting the results.
In addition, there is no consistent and constant lecturer's record keeping system in the university. Moreover, it has no significance rather than getting some number as a score. This is because no one is going back to the score to check the efficiency of the lecturer to provide feedback and to establish follow-up system of lecturers. Even the lecturers themselves could not see the individual student's feedback, every score in each measurement parameters, overall strength and weakness, etc. Due to this, the lecturers have no mechanism to know themselves professionally, to improve their work, to upgrade themselves, to increase their readiness. Also the head of the department as well as other concerned bodies have no mechanism to get gaps in the lecturers and to provide continuous professional development in the university to achieve quality of education. This shows that, in the current lecturer evaluation, there is lack of suitable implementation and following up processes. The real purpose of lecturer's in strengthening the teaching profession is declined by the condition of inadequate implementation [2].

General Objective
The main objective of this study is to examine the use of yearbook efficiency management system to monitor lecturer's performance.

Specific Objectives
The specific objectives of this study are: • To conduct the challenges and potential uses of lecturer's performance evaluation and monitoring.
• To identify the specification of intranet based lecturer's performance evaluation system • To design the system including the backend and frontend • To develop, test and implement the prototype of the system

Significance of the Study
The output of this study is very necessary and important because of the following reasons.
• Every semester's lecturer overall performance will be monitored.
• Evaluating, calculating, reporting and accessing lecturer's performance will be easy.
• The resources and efforts required to generate report, keeping records and analysing lecturer performance will be easy.
• It will allow all the learners to participate in the evaluation process.

Overview
Performance evaluation is the ongoing process used to identify, assess and improve the performance of individual educator in line with the institution's main objectives [8]. Lecturer's performance evaluation is a process in which higher education institutions use to review and rate lecturer's performance and effectiveness. The results are used to indicate lecturer's performance and to provide feedback for area of improvement and support as well as to recognize and reward lecturers [9]. Therefore, improving the evaluation process itself is required for educational success [10].

Impacts of Performance Evaluation in Professional
Development of Lecturers Inappropriate efficiency results of lecturers greatly impact the learners and educators by influencing both to have fake personality. This is because sometimes the evaluation is conducted for the sake reporting [8]. However, it must be for identifying, measuring and developing an individual's performance.
Real implementation of performance evaluation is the best way of improving professional development of lecturers [11]. To achieve quality education through well performed lecturers, technology based evaluation is the top and effective form of lecturer's performance appraisal to reward and recognize the best lecturer. Therefore, the technology based performance evaluation is very important for professional development and quality of education so that area of improvement for lecturers can be easily identified.

Intranet Based Web System to Monitor Lecturer's Performance (IBWS-MLP)
Appraising performance of lecturers will be interesting and easily accessible if it is supported by web based system. It provides a number of benefits like elimination of printed evaluation forms, keeping of accuracy, confidentiality and integrity of evaluation data, generating timely and accurate report, increasing participation of students in the evaluation process, saving costs and others [12]. The process of evaluating lecturers involves three parties: students, colleagues and the head of department. The head of department is at the center of managing lecturers' evaluation. In the context of Assosa University, Ethiopia, web based tool is required for its effectiveness, to create easy communication among all parties and to establish follow up mechanism. Therefore, there is need for a system to manage lecturers' evaluation process and to help lecturers to use the evaluation result for performance improvement. In this study, yearbook efficiency management system is proposed and implemented to monitor the performance of lecturers.

Modules in IBWS-MLP
The following seven important modules are examined for the proposed system. Additional modules can easily be integrated into the system so that system functionalities are decomposed according to modules which are recommended approach to handle design and implementation tasks [13]. The modules are: • User module (HoD, student and colleagues or lecturers in the same depart-

Design of the IBWS-MLP
Designing of a system is the process of defining the system element and it can be expressed using different techniques. In this work context diagram is used to show the design of Yearbook Efficiency Management System. This is because it can easily demonstrate the overall system and its interaction with the external entities which is a level 0 data flow diagram. Four entities are involved in the design of the prototype system shown in Figure 1 below. The first entity is HoD or administrator who represents the department office and plays a central role to manage the system, the second entity is the lecturer that will be evaluated, the third and fourth entities are the students and colleagues who plays a role of evaluator.

Design of Algorithm for Selected Process of Performance Evaluation
Description of Problem: improving lectures performance evaluation process and result keeping using intranet based web system. Objective: to develop intranet based lecturer evaluation system to monitor their performance. Process of performance evaluation 1: Name: Head of department (HoD) Input: the HoD enters the URL of lecturer's evaluation system Output: it displays a page for userID and password Description: this interface is used by the HoD and is used to display the login page

System Prototype
The lecturer's performance evaluation system is designed to be easy to navigate, simple to look at, easy to access the evaluation form and frequently used data, user friendly and easy for students, colleagues and HoD to evaluate the lecturers on the web. We tried to adopt human computer interaction (HCI) principles in the process of designing user interface [14]. Also user guide is provided as a reference to the users of the system. The technologies that were used for development of the prototype are: HTML5, CSS and bootstrap open source framework for designing the web interface of the prototype, JavaScript and JQuery to write client side logic like validation and form submit, PHP language to write backend side or server side business logic of the prototype, MySQL to store all the evaluation data or as a database system and phpMyAdmin as PHP and MySQL administration tool. Figure 2 below shows the login interface for all users. Currently, three system users such as HoD, students and colleagues has been implemented. Each user have different navigation in their interface, however the overall graphical user interfaces are consistent and similar for all functionalities. Figure 3 shows the page for HoD to manage lecturer performance evaluation. It list down all the lecturers in the department with assigned courses and sections of students as well as semester points of the lecturer given by students. Also the HoD can add new lecturer in the system by assigning course and section of students. The HoD can follow up lecturer performance progress by selecting individual lecturer from the list based on students' evaluation. The status is displayed using different background and text color based on its progress. The color used are white to show that the evaluation is not began, yellow to show that the progress is good, blue to show that the progress is very good, green to show that the progress is excellent and red to show that the progress is poor. Yet, this feature can be improved by designing more in-built symbols.  Figure 4 below shows the page for students to evaluate lecturers. The students can select the lecturer to evaluate based on the listed criteria and the course he/she teach in that semester. After that they can submit the result to the department by clicking on finish and submit button.
Another important feature of the lecturer's evaluation system is its ability to calculate and generate semester and yearly result of lecturers. The process of evaluating lecturers involves three parties: students, colleagues and the head of department. At the beginning of each semester, the head of department assign a lecturer to teach a specific course in one or more sections. After that it is lecturer's responsibility to handle the given course or to teach and assess students (up to recording the students' grades into the university student information management  At end of the semester, the head of department activates lecturer's evaluation questionnaires form for students to evaluate their lecturer for specific course. After the students fulfil the form, course and lecturer information, they submitted to the head of department. Similarly, the head of department activates lecturer's evaluation questionnaires form for colleagues (other lecturers in the same department) and the colleagues resubmit the evaluation form to the department after evaluating their staffs. It is then the head of department evaluates each lecturer using the HoD evaluation criteria using the proposed system. Lastly, the efficiency of the lecturer is calculated by the system. This is by analyzing the lecturer's result given by each student, colleagues and HoD itself separately and the average point is recorded as a semester efficiency of the lecturer. In the same way, the second semester efficiency is calculated and recorded. Finally, yearly efficiency of the lecturer, which is average efficiency of the two semesters' is calculated and recorded.

Evaluation
The yearbook efficiency management system was evaluated by expertize from the area of computer science, information Technology, education and software engineering at the early stage of the design to check its functionality and usefulness of appraising and monitoring lecturer's performance. To check the workability of the developed solution, system test was performed through unit testing, integration and usability testing. The evaluation was done by taking sample test cases and by observing and checking expected outputs which is discussed below.

1) Unit Testing

2) Integration Testing This system was integration of different components and tested based on unit module, completeness of module and by creating integrated test condition for all modules. As shown in Table 2, the following integration test conditions were used.
• Efficiency result and comment storing and retrieving test, file processing test and search test were checked. Each module are validated based on providing input and using output • Integration was done for evaluating lecturer, analysing and calculating efficiency score, generating efficiency report and monitoring lecturer's performance 3) Usability Testing Usability test was done on the perspectives of head of departments, students and colleagues. This test was performed on how all the above users use the system and attractiveness of the interface to use. They used the designed user interface and other features of the developed system. Finally, they suggest different additional issues that are to be included in the system. Therefore, usability testing was done with 45 students, 3 head of departments and 30 colleagues from three different departments in the university. To test the system, each group of the above users uses their own pages that created for them. And evaluate the result in terms of usability of the system on the university local internet. The result analysis of the system uses Likert scale in rating. The ratings are 1 (poor), 2 (fair), 3 (good), 4 (very good) and 5 (excellent).

Research Design
Research design is the main part of any research work and there are a number of approaches based on the nature of the study. Design science research methodology is one of the design approaches in the area of computer science and software engineering [15] [16]. It creates an artifact by artificial object and its basic objective is to produce new knowledge during this process. It is mostly focus on knowledge flows and process steps that is problem awareness, suggestion, development, evaluation and conclusion; eventually aims to get result or output [17].
To show the usefulness of the yearbook efficiency management system for monitoring the performance of lecturers, design-oriented research methodology was used. Design science research method is basically a problem solving model [18]. The five steps of design science method followed in this study are identification of problem, suggestion of solutions, application development, evaluation and conclusion.
1) Identification of Problem In this study, the first step was to identify the problem by examining the current practices of lecturer evaluation and by reviewing the available literatures to acquire understanding and to get its problem domain. Currently, all Universities in Ethiopia uses paper based lecturer's evaluation technique in which the filled data can be lost at any time and only 15% -25% of learners are participated in the evaluation process. Moreover, the process is resource, time and effort intensive to prepare, pack, distribute, collect, record, analyze, store and report the result.
2) Suggestion of Solution The second step was to identify various solutions that can solve the problems of lecturer's performance evaluation and monitoring process. In this regard, intranet based web system is proposed as a solution to monitor lecturer's performance.
3) Development of Solution The third step was the development of the selected solution. Here, yearbook efficiency management system was designed and implemented which is intranet based web system to evaluate and monitor lecturer's performance.

4) Evaluation
Evaluating the designed and implemented solution was the fourth step in this study. The developed yearbook efficiency management system was evaluated using the different stages of software development testing techniques. So, unit testing, integration testing and usability testing was done accordingly.

5) Conclusion
The final step of this study was to put concluding remarks based on the results and discussion of the study and the evaluation of the proposed solution for the specified problem.

Results and Discussion
The current practice of appraising lecturer's performance is through paper based method where the evaluation questionnaires are prepared, printed, packed, distributed, collected, recorded, analyzed and reported manually by the head of departments and other facilitators.
The paper based evaluation process had many problems during its implementation [12]. The first problem is related with the required time to record, analyze and generate report which takes a long time. The second problem is regarding to the number of students participated to evaluate their lecturers. In this regard, because of the manual evaluation process is resource and time intensive to prepare, record and analyze the result, only 15% -25% of the students were participated in the evaluation process. So, all the students had no chance to evaluate their lecturers. The third challenge of paper based evaluation is connected with inappropriate result given to lecturers. This is because of the lecturer is being there during evaluation time and the students fear of facing challenges by connecting the issue with grade mark, they may gave high score even if he/she deserves the lowest score. The forth problem is the cost of printing and recording points for each evaluation parameter. The fifth problem is regarding to the limitation to share the efficiency results of lecturers when needed. Because the result is printed and putted on the shelf, academic managers can't access the information when they need. The last but not the list challenge of paper based evaluation process is related with confidentiality, data accuracy and integrity which is under question. Because of more than one person is participated in the conduct and data encoding process, it may not be confidential. Also, error may happen intentionally or unintentionally when evaluation score is entered in to computer for processing. As a solution of solving the above discussed and other related issues of the evaluation, intranet based lecturer's evaluation system was designed and implemented in Assosa University, Ethiopia. So, the use of intranet based lecturer's evaluation system in current context is due to the problems faced by universities to appraise and monitor the actual lecturer's performance to establish follow up system and professional development program. As known, technologies have a potential to achieve radical change in many sectors including education and training [12] [19]. This is because, technology based lecturer performance evaluation have a lot of potential uses from preparation of evaluation to result reporting and improvement of lecturer's profession to achieve quality of education [2]. Compared with the manual way of lecturer evaluation, it is effective in evaluating and monitoring, accessible when needed, it saves cost and eliminates printing of papers, allows participation of all students in the evaluation process with the absence of any lecturer or facilitators during the evaluation, confidentiality, integrity and accuracy can be easily maintained, timely and accurate re-port which allows retrieval of specific and detail information from digital media. Therefore, there will be monitoring of lecturer's teaching performance with in-depth analysis of lecturer performance report to provide feedback and recommendation, to assign the right teaching load, to prepare training and professional development by allocating budget as well as to recognize and reward the best performer. However, there is security issue which requires specific and serious protocol that must be enforced during the evaluation period.

Conclusion and Future Directions
In higher education institutions of Ethiopia, lecturer's efficiency result has not been produced noticeable contribution for the improvement of lecturer's performance and to establish professional development method. This is because of the lack of technologies to evaluate the performance of lecturers, to establish monitoring mechanism and to find professional gaps. In this study, we proposed web based lecturer's yearbook efficiency management system as a tool of performance improvement for lecturers. Different modules of the prototype of the system have successfully been developed and integrated into the final version.
The developed intranet based web system is used to monitor lecturer's performance and to establish professional development and follow up system.
In the future, we planned to automatically analyze the comments given by students, colleagues and HoD to generate report. This is by integrating the concept of NLP and AI to categorize and summarize comments as strength and weakness. Also we planned to integrate the yearbook efficiency management system with the university registrar, academic program development and human resource management system to cluster lecturer information for later use.
