1.2 Background of Study

E-education is the process of learning online. Whether you’re a high school student or a graduate college student, a person looking to expand technical skills or a retiree who simply wants to learn more, electronic learning provides a boundary-free way to broaden your horizons that allows the teacher to be able to communicate with its students across the web either through receiving lectures or assessment (electronic tutoring and electronic assessment) and also delivering any other information that is necessary for the student’s progress .This application is developed on the web which comprises of three tiers which are the client, the server and the database, the server and the database are the part of the system that would be used by the teacher to hold the resources to be displayed as well as editing of such resources .The server and the database can be said to work hand in hand and used by the same person, while the client tier is used by the student to view the resources as well as interacting with the lecture. These three tiers can be interacting with one another to create an online and real time application. These tiers can all work hand in hand to create an effective communication between the teacher and the student.

These have been an increased interest in the area of computer technology in Nigeria through the introduction of the internet. This has aided communication between two distant parties in the country, there by enlarging the interest of electronic learning in Nigeria. The e-learning system comprises of two main section, the electronics tutoring (e-learning) and the electronics assessment (e-assessment) .The e-tutoring aspect is concerned with the learning part where student come on line to receive lectures, take review questions and also view summary and the note key of lecture received. The e-assessment section is just where the student take tests, exercise, quiz to know how far they have learnt since the commencement of the lectures.

An Electronic Learning framework carries education nearer to the individuals and evacuates the pressure and imperatives, which characterize the conventional classroom learning system. The hallmarks of Electronic Learning are the separation of teacher and learner in space and/or time, the control of learning by the student rather than the distant instructor, and non-adjacent communication between student and teacher, mediated by print or other forms of technology. At its most essential level, distance education is a procedure where number of teachings is conducted by remotely located lecturers. Two categories of Electronic Learning systems exist; namely On-line and Off-line Electronic Learning. On-line Electronic Learning, also known as virtual classroom is a type of learning system in which students work on their own at home or at the office and communicate with personnel and different studies by means of email, electronic discussions, videoconferencing and different types of PC based correspondence.. Off-line Electronic Learning on its own is a multi-campus system where a University or Polytechnic establishes many campuses and each of these campuses may be centrally controlled or decentralized.
