THE EXTENT OF AVAILABILITY OF COMPUTER SYSTEM AND THEIR ACCESSORIES FOR EFFECTIVE TEACHING AND LEARNING OF BIOLOGY IN SENIOR SECONDARY SCHOOL

ABSTRACT

The study was conducted to investigate the extent of availability of computer systems and accessories for effective teaching and learning of biology 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 biology in schools, are largely unavailable. Based on this, some implications of the study and recommendations were made.

CHAPTER ONE

INTRODUCTION

BACKGROUND OF THE STUDY

The best approach to effect study of computer depends on the extent of the practical aspect of teaching computer. The aspect of this study has to do with the availability of computer system and their accessories. Aneke I.C. (2005). Computer system is a programmable machine which responds to a specific set of instruction in a well defined manner. It can execute a pre – recorded list of instruction ( a program). The place of computer in education, like in any fields of human endeavor, has assumed an unimaginable dimension. Today, computers are used in various ways for teaching and learning in schools at various levels. Computes can now guide a learner through a course of instructions at a video display unit in such a manner that 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 instructions to students, ask them questions (usually multiple choice question) mark the students responses, grade their performance and determine by itself whether to take the students to take the students to next level of 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 programs, computers also make a lot of impacts I provision of educational materials. Computer transform school libraries into new information service unit. Through virtual library one oleos not need to go from one library to another in search of library materials. With just a press of button (keys on computer keyboard) or 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. E.g. keyboard, scanner, printers, mouse, monitors etc. Extent through which these 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 Enugu North in particular. In this sense that the hardly make use of the system due to non installation of these accessories in the 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 must be available to an extent that is to say that 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 maintance of the available computer system and accessories.

Statement of the 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 researcher has put some question to enable them set information at the course of the investigation. Computer system is the best approach to the studding of practical’s in computer education, why are there less computer system in the computer system in the computer lab of the school?Accessories are those devices 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 was designed to find out the extent of availability of computer system and their accessories for effective teaching and learning in senior secondary schools under Enugu north local Government Area. The major aim of this research work was to find out:

1. The extent of availability of computer systems and their accessories for effective teaching and learning of biology.

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 maintance of available computer system and their accessories in schools.

Significance of the study

The study is expected to bring out results and good information on the extent of availability of computer system and their accessories for effective teaching and learning of biology 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 materials is of benefits to educational administrators to achieve their objectives 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 introducing computer education in Nigeria. This strategy includes: 

Training teachers and associate personnel.

Hardware facilities 

Curriculum development 

Software development and evaluation 

Maintance of hardware and peripherals

Scope of the study

This study is meant to discover the extent of availability of computer systems 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, 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 systems and accessories available in schools?

2.  What teaching method are used for teaching biology?

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?
