THE EXTENT OF AVAILABILITY OF COMPUTER SYSTEM AND THEIR ACCESSORIES FOR EFFECTIVE TEACHING AND LEARNING OF COMPUTER SCIENCE IN SENIOR SECONDARY IN ENUGU NORTH LOCAL GOVERNMENT AREA
ABSTRACT
The study was conducted to investigate the extent of availability of computer systems and accessories for effective teaching and learning in senior secondary schools in Enugu North Local Government Area. The population of the study consisted of two hundred and forty teachers and students in senior secondary school in Enugu North L.G.A simple Survey research was used for the research design and simple random sampling techniques were used to select the subject for the study which is one hundred and forty (140) were administered,( 120) were returned duly completed while twenty (20) were not returned. Four (4) research questions guided the study. The questionnaire was used in data analysis. A mean of 2.50 and above was adopted as a cut of mark for the acceptance of items. The result findings showed that the computer systems and accessories for teaching and learning computer science in schools, are largely unavailable. Based on this, some implications of the study and recommendations were made.

CHAPTER ONE
Background of study.
The best approach to effect study of computer on the extent of the practical aspevt of teaching computer. The aspect of this study has to do with tha availability of vomputer system an thir accessories. Aneke I.C (2005). Computer sstem is a programmable machine which respond to a specific set of instruction in a well defined manner.  It can execute a rerecorded list of instruction (a program). The pace of computer in education, like in any fields of human endeavor has assumed an unimaginable dimension. Today computers are used in various ways for  taching and learning in schools at various levels.  Computers can now guide a learner through a course of instructions at a video disply unit such a manner thet will facilitate the understanding of subject matter. This process helps to speed up the students learning process. This practice unlike the case of human teacher gives the opportunity to re-learn any aspect of the subject matter as many times as he/she cleans it necessary. This process of learning is called computer – assisted learning (CAL). Computer can also provide instruction to students, ask them question (usually multiple choice question) Mark the students to take the students to nect level of the study or repeat the previous portion of the lecture just concluded based on the students performance. This process of learning is called computer aided instruction (CAI). Apart from instructional programme computer also make a lot of impact in provision of educational materials. Computer transform school libraries into new formation unit. Through virtual library one does not need to go from one library to another in search of library materials. With just a pres of button (keys on the computer keyboard) a click on the mouse the information will be at the disposal of the intended user. According to Aneke, accessories are those devices which are useful, helpful to the operation of computer for example, Keyboard, scanner, printers, mouse, monitors etc.
        Extent through which the accessories are seen in the tab is the major aim of these studies. Unavailability of computer accessories are of the problem facing Nigerian students at the North in particular. In this sense that the hardly make use of the system due to non- installation of these accessories in he computer. In other to maintain the of 32nd ministerial council meeting of the national council of education in 1987, which is to set-up computer study at the secondary school level. These accessories most be available to some extent that is to say that the installation of accessories will enhance the smooth running of programs for the betterment of the students learning.  This research work will provide necessary steps to the secondary schools and steps for maintenance of the available compute system and accessories.
Statement of problem
        The researcher wishes to find the extent of availability of computer system in secondary school, in Enugu north by finding out of the number of computer system in the school will be enough for the student at the course of practical and the availability of the computer accessories in other to enhance effective program running in the system for the purpose of this work. The researche has put some questions to enable them set information at the course of the investigation. Computer system is the best approach to the studding of practical in computer education, why are there less computer system in the computer lab of the school?
        Accessories are those which are useful, helpful to the operation of computer, why is it that the accessories are not available in the computer lab?
Purpose of the study
The study designed to find out the extent o availability of computer system and their accessories for effective teaching and learning in senior secondary schools under Enugu local government Area. The major aim of this research work was to find out:
1.    The extent of availability of computer and their accessories effective teaching and learning of computer science.
2.     The methods used by the teachers in their teaching
3.     How often are the learners exposed to practical knowledge of computer?
4.    The extent of maintenance of available computer system and their accessories in schools.
Significance of the study
    The study expected to bring out result and good information on the extent of availability of computer system and their accessories for the effective teaching and learning of computer science in senior secondary schools under Enugu north education zone. The findings of this study will be of benefits to students, teachers and educational administrators. The students may stand to benefit when the computer system and their accessories are available in the lab for practical in order to enhance effective teaching and learning. The teachers work will be made easier when instructional material are adequate and upgrade following stored information in the computer. This material is benefits to educational adminisators to achieve their objective which is to set up computer study at the secondary school level as to well as devising clear strategies and technologies to be used by the federal and state government in introducting computer education in Nigeria. This strategy includes:
Training teachers and associate personnel
Hardware facilities
Curriculum development
Software development and evaluation
Maintenance of hardware and peripherals
Scope of the study
    This study is meant to discover the extent of availability of computer system and their accessories in senior secondary schools within Enugu North Local Government Area. The accessories expected to be seen in the schools include:
Input devices such as keyboard, mouse etc
Output devices such as monitors, scanner etc
Installation of software including system and
Application software
Equipped computer lab.
Research Questions
For the purpose of this study, the researcher has proposed the following research questions.
1.    To what extent are computer system and accessories available in schools?
2.    What teaching methods are used for teaching computer science?
3.    To what extent are the learners exposed to practical computer packages?
4.    To what extent are the computer systems maintained for effective teaching and learning?
