DESIGN AND IMPLEMENTATION OF A WEB ENABLED ON-LINE TUTORIALABSTRACT
This project was centered on web enabled visual basic online
tutorial. The current process of teaching and learning is being done
manually and due to this procedure the learning process is slow and not
encouraging. A design was taken to computerized the manual process in
order to check this problem. The problems were identified after series
of interviews and examination of documents after which analysis was
made and a computerized procedure recommended. This project will also
suggest how to successfully implement the computerized procedure and to
overcome the obstacle that would hinder the successful implementation
of the system. The new system was designed using Hypertext markup
its easy syntax and features for developing online based applications.
Visual basic (VB) is the third generation event-driven programming language and integrated development environment (IDE) from Microsoft for its programming model. Visual basic is also considered as a relative easy to learn and use programming language, because of its graphic development features and basic heritage. Visual basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications access to database using Data Access objects, Data objects, or active data objects and creation of active X controls and objects.
With every little effort, the programmer can design a screen that holds standard windows elements such as command buttons, check boxes, option buttons, text boxes and list boxes. Each of these windows objects operators as expected, producing a “standard” windows user interface.
Visual basic is easy to learn, which makes it an excellent tool for understanding elementary programming concepts. In addition, it has evolved into such a powerful and popular product that skilled visual basic programmers are in demand in the job market.
The purpose of this project topic on design and implementation of a web enabled visual basic tutorial is to present to student with a big picture on visual basic online teaching or tutorial so that students of Federal College Agric can be able to go the website and learn the application of VB and its importance to human existence. It enables the students to learn at their own pace.
In this chapter, we begin with a discussion of how the design of website on visual basic tutorial has traditionally been driven by the role they play and the services they provide. The problem of designing this website in order to provide services like learning and teaching are also considered. The general discussion of the designation of website on visual basic tutorial and the essential function they provide must be presented in this project.
Visual basic enables an individual to program easily. It is an object oriented programming language. It has tool bars, properties and other main menu that helps to create a beautiful project outlook.
Here is an example of the language: code snippet that displays a message box “hello world” as the window forms load.
Private sub form load ()
‘Execute a simple message box that will say “Hello world”
Msgbox “hello world”
1.2 BACKGROUND OF THE STUDY
BACKGROUND HISTORY OF FEDERAL COLLEGE OF AGRICULTURE, ISHIAGU
The federal college of agriculture, Umudike now at Ishiagu as the training wing of national root crop research institute situated at Umudike, in Abia State. She still trains staff of NRCRI in Advance Certificate, National and Higher Diplomas.
The relocation of the college to Ishiagu in1993 made way for the establishment of federal university of Agriculture now Micheal Opera university of Agriculture, Umudike.
Ishiagu being the new location is quite suitable for academic and agricultural work. Presently, the college occupies an area of 200 hectares.
Aims and Objectives
The college will aims at excelling in every aspect of Agriculture and capacity building of middle level manpower (ND and HND) in practical and theoretical Agriculture. It has the under listed objectives for efficient performance and achievement of the target.
To develop and run training programmed that can produce self-reliant agriculture technologies and technicians for the agricultural industry. M To meet NBTE accreditation standards, expand and diversify programmed that are cost effectives.
To maintain a close link industries related to agriculture and ensure that our products meet their needs. This will provide adequate SIWES places and opportunities for some employment to our student in the private sector.
1.3 STATEMENT OF THE PROBLEM
In an institution like this, Federal College of Agric the method of admission is very alarming for instance, in a department like computer science Tech., the number of intake of ND student are 80.
In a situation like this, you find out that learning programming language generally poses a big problem. This I turn forms constraints that will slow down the peace of growing versatile in area of academic.
Even in my course of research, I found out that there are other departments who ought to do the course, for instance computer sc. Tech but owing to the constraints involved, I therefore drew out some problems that could be the course
1. DEPARTMENT COMPUTERS
Since the learning of visual basic requires practical, the students are limited from knowing how the program works because of some computers activities in the lab. Sometimes, the students are made to stay 3 people each on one system, you know what that means, and concentration will be lost.
Like as I said earlier, over population can hinder a student from learning. This is because, the atmosphere will be stuffy owing to the heat exerted from the bodies or skin of students. The environment will be unconductive and sometimes seats are occupied and others.
1.4 PURPOSE OF THE STUDY
The purpose or aim of the study is to provide a website on visual basic online teaching where the students of federal college , will go and learn, make research, and gather facts on any information they want on VB. This will help to improve student’s attitude and make them to become good programmers despite their area of discipline in the institution.
Another point is also to enable student become versatile in all area of academic work. Since we are in the computer age, information and communication technology has cropped in every nook and cranny of this world. Even the illiterate ones have realized the applications of computers.
Learning visual basic in a big institution like this makes the students to understand all about object-oriented language. You can imagine students from the department of mass communication, political science, public administration etc writing a program on VB. This generally means that this website will enable the student to learn at ease, in a more conducive atmosphere without any obstruction or disturbance. As a matter of fact, the project is going to be hosted on the internet to allow students to browse through and thus enhance their intellectual capabilities and learn beyond the traditional classroom lecture.
1.5 SCOPE OF THE STUDY
The scope of this study will be strictly on COMPUTER SCIENCE precisely. Though schools can still have access to the teaching but in order to reduce the compellability of the science. This will be done to enable the students to be fully baked and grinded on this wonderful area of learning. So that when they enter the labour market, they will be expert on the field.
All computer students from ND to HND are free to go to the internet and browse, make research, practice what they have learnt inside the classroom teaching and still expanciate their knowledge on programming concept. This in turn will generally increase their skills, knowledge, vision and intelligence on the aspect of VB language.
1.6 SIGNIFICANCE OF STUDY
Since the purpose of this project is to design a website on visual basic tutorial, students will therefore benefit from this study as it serves so many goals or importance.
This site will provide to the students, the preliminary concept of programming and its importance.
It will enable students to design a project on their own like employee payroll of a company and writing codes.
It will make the students to be an expert in visual basic program and become a demand in the job market.
The learning of VB via the online lecture can enable one become a tutor, a consultant in firms like banks, schools because with the employment of a VB programmer, complex work is now lessen in the organization.
With the knowledge of visual basic, the student can program visual basic, Net, C+, and Pascal. C++ and other promising programming languages.
The knowledge of VB can make an individual to be a software developer.
1.7 LIMITATION OF THE STUDY
In a big project like this, so many limitations was encountered. Financial problem was a very big hitch to this project in the sense that some foreign textbooks needed to properly build this project was not bought.
Another limitation was the limited time embarked to carry out the research work as the research was combined with welfare and other academic work which was tedious.
The researcher was limited to some vital information in the library due to some security reasons from the librarian. The time spent in understanding the vast function of visual basic and the complexity of the program constituted a lot of worries during program development. Visual basic is too vast and very complex in designing but very interesting in analyzing the applications and functions.
Moreso, the HTML program gave me a big problem and concern as it is very difficult to code, making it look much complex.
