EVALUATION OF EXAMINATION BOARDS WEBSITE IN NIGERIA
CHAPTER ONE
INTRODUCTION
1.1 Background of the study
A user interface (UI) is the intersection of a product and a user. The commands in a computer application, the steering wheel, gas pedal and brake pedal in a car are all examples of user interfaces. The term 'user interface'is often used in relation to a computer interface. In this context, a user interface is characterized as, "the parts of a computer system or program which can be seen (or heard or otherwise perceived) by the human end-user, and the commands and mechanisms the user uses to control its operation and information." (Galitz, 2013). The ideal website would be perfectly clear to new users, quickly provide them with the information they need, easy to use even after a long period of time, error free, and provide the user a very pleasant experience. Unfortunately, few interfaces are as such. Websites are often poorly laid-out, making navigation uneasy. Applications often have poorly labeled buttons or unclear prompts. New users often get confused by unclear layout, and returning users often get frustrated by awkward ways of entering data. To prevent these problems, interfaces need to be designed for usability.
To measure and improve usability, usability evaluations are mostly done. A usability study is an essential tool for evaluating a user interface in which the effectiveness of the user interface is judged. Based on the results, changes would be made to improve the interface. However, "Usability is the degree to which individuals (users) can perform a set of obliged tasks. It is the result of a few some of the time clashing design objectives." (Brinck, Gergle, & Wood, 2002) Usability has been characterized by diverse individuals who claim it makes out of distinctive segments.
1.2 Statement of the Problem
In a research study on user's satisfaction with examination board's websites, users cited issues such as redirecting to another website to solve errors, wrong allocation of information, double registration for a student who was registered once as a source of difficulty while registering students. It was additionally noted that while most users pointed out the strengths, just a couple analyzed its important restrictions and problems.
The requirement for giving reliable direction for instructional online registration can be gotten from a few wellsprings of dissatisfaction. Contrasts between web designers and users have as of now been recognized as lessening fulfillment in light of the fact that web site design has not concentrated basically on user needs. Sometimes the users of examinational websites are not pleased with the website and this result in less usage of the website which leads to not achieving goals of the websites.
There is a need to look at the nature of instructional websites from the points of view of both adherence to acknowledged design standards and the viewpoint of users who definitely, after enlisting students, have contrasting levels of former information, computer experience and mastery.
1.3 Aim and Objectives of the Study
The general purpose of this study is to evaluate the usability of websites of examination bodies in Nigeria. The objectives are as follows
1.4 Significance of the Study
The importance of registration as well as result checking on line is very vital to the examination boards in Nigeria. It is expected that the results from the findings of this study will be used to evaluate the usability level of the websites (NABTEB, WAEC and NECO) correctly. Hence, areas where improvements are needed as well various design issues and violations will be pointed out. The result obtained will be used to build a better, usable and accessible website which will make the navigation and other user activities easier. Based on the testing results, the original sites will be improved and tested again.
1.5 Scope of Study
This study is based mainly on the usability evaluation of examination board's website. The three examination boards used in this study are: National Business and Technical Examination Board (NABTEB), West African Examination Council (WAEC) and National Examination Council (NECO).
1.6 Limitations of the Study
This study due to a few factors, some of which are; limited time, financial restraints, have been limited to three usability evaluation methods, which are; questionnaire based method, interview and accessibility testing not including heuristic evaluation
