INTRODUCTION
1.1   BACKGROUND OF THE STUDY
The present study is undertaken to determine the various strategies to enhance teaching and learning of computer science in secondary schools. The major findings were that employing qualified and professional teachers and the creation of a conducive academic environment and PTA body could enhance the teaching and learning of computer science. The need for the provision of financial support by some philanthropists and communities will also enhance the teaching and learning of computer science in secondary schools.         
 Computer science, is science subjects who are concerned with gaining knowledge about man’s contained search for a toll that will enable him meet his computation and data processing requirement with a minimal, manual and mental effort.Consequently, the educational implication of this finding has a for reaching effect on both the society and the general economy. Thus, a society without a computer literate workforce will definitely lack behind in an age that is variously regarded as a digital age information age and millennium era and computer age.

1.3 IMPORTANCE OF COMPUTER
The importance of computer cannot be over-emphasized considering its assistance to mankind in terms of business, industry, Government and law enforcement, banks, in biological, physical and social sciences, chemistry and physics, fine art, education and in home etc.          
For instance, the computer is playing an increasingly important role in society, particularly in industrially developed countries. Its usage can be seen in various ways, which includes: --        
-It helps to find a move in a game of chess-        
-It helps to transfer finds from one bank to another-        
-It helps to calculate their employee’s wages and print pay roll cheque.-        
-It helps record the amount of money deposited and withdrawn by customers for type setting books, magazine and documents.-        
-It stores a vast amount of data.-        
-It checks tax returns each year-        
-To finger print daily-        
-To store even crime statistics, license numbers of store cars in the computer database.-       
-To plan troop man over.-        
-To analyze experiment data used to guide telescope and other objects in space.-        
-To find out various major illness (e.g. in diagnosing brain turners and certain other disorders.-        
-It is also used for lectures through a step-by-step lesson.Used to play the music stored in our CD-ROM used to scan picture into document for publishing used for sending mail to a friend across the globe.
