DESIGN AND IMPLEMENTATION
OF AN
SYSTEM
PRESENTED BY
LAWANI TOMILAYO IKPONMWOSA

INTRODUCTION
 Education is usually perceived as the method whereby we have students in a classroom receiving
lessons from a Teacher but with the help of information technology through the internet,
learning can now be achieved without necessarily having a teacher right in front of a student.
 E-learning is one of the tools that emerged from information technology and has been integrated
in many universities education programs, shifting from the traditional way of education to
electronic environment in which a student can access and make use of information anywhere
and at any convenient time.

PROBLEM STATEMENT
 Students' inability to grasp key ideas and concepts.
 Too much focus on presentation, little time left for practice.
 Lack of motivational push.
NOTE: This method of education is therefore a danger to the student as this will only make the
student unqualified for the career industry.

AIM AND OBJECTIVES
AIM
The aim of this project is to develop an e-learning system that will improvise on the manual, large
class learning techniques used in teaching Computer Science
OBJECTIVES
The objectives of this project are as follows;
 To design an e-learning system with various multimedia features.
 To integrate concurrent access features in the system
 To create a database for easy retrieval, storage and maintenance of student records as well as
sharing of data between users.
 To make the training process easier for the trainer as well.

LITERATURE REVIEW
 Origin
The origins of the term e-learning is not certain, although it is suggested
that the term most likely originated during the 1980's but the term “e-
learning” has been in existence since 1999 where it was first used at a CBT
systems seminar.
 Types of E-learning
Source: (Hrastinski, 2008)
There are four major categories
of users of an e-learning system
which includes;
 Students
 Instructors
 Authors
 System developers

LITERATURE REVIEW
 The tools includes chat rooms, discussion groups, online bulletin boards, and e-mail support access to
instructors, but they all essentially pertain to asynchronous mode of learning. The most sophisticated and
the most interactive environments provide tools for synchronous mode of training and learning, with
instructor(s) organizing and guiding learning/training sessions in real time.
 In addition to Internet Web sites, supporting tools include audio and/or video-conferencing, Internet
telephony, or even two-way live broadcasts to students in a classroom (Devedzic, 2015)

REVIEW OF RELATED WORK
 W3Schools is optimized for learning, testing, and training. Examples might be
simplified to improve reading and basic understanding. Tutorials, references, and
examples are constantly reviewed to avoid errors.
 Coursera provides universal access to the world’s best education, partnering with
top universities and organizations to offer courses for anyone to take, for free.
 Code. Org is based on the idea that every student in every school should have the
opportunity to learn computer science
 Tutorialspoint makes available an Online Lab where you can create your programs
in more than 80 programming languages, compile, execute and share them over
the web, which provides you remarkable learning experience at a cost of just an
internet connection.

METHODOLOGY
 It makes use of a CMS
(Content Management
System) technologies to
store course contents,
test results and student
records.
 The server side technology to
be adopted is PHP which is a
scripting language in which a
user generates a request to a
server (SQL Server), the server
analyses this request and
generates a response back as
HTML code through the web
browser to the client. This
scripting language is used so as
to ease integration within
mark-up language and because
of its capability to generate
dynamic HTML.
 The client-side
technology to integrate
is JavaScript which will
generate the events
directly on the web
browser. This is adopted
so as to reduce the time
needed for the server’s
interrogation and
response delay and to
create visual a functional
effect similar to desktop
applications.
 The interface design will
be a core, integrated
component of the
overall design of on-line
units and it will also be
determined by how
people learn and the
tasks they need to
perform.
