CHAPTER ONE
1.0              INTRODUCTION
1.1       BACKGROUND OF THE STUDY
            Education is an important sector which cannot be fun with any serious country, state, organization or individual and that is why an individual, organization or government uses every means to make sure a good education is provided for her citizens (Adibe, 2001).
            One of the means of this provision is the introduction of computer science in polytechnics, as a course of study.
            Computer science is the study of the design and use of computer systems. One goal of the computer science department is to provide  the student with the tools to identify those problem that are best solved by means of a computer and to design and implement effective, economical, and creative solutions.
            Computer science as an academic discipline systematically includes three domains: Theory, and abstraction, and design.
            The curriculum’s required courses give the  students a strong foundation in both the software and hardware aspects of computing, as well as the mathematics and science that underline the discipline. The electives in the later years allow the student to study more deeply some particular area of computer science. The department courses and programmes  continue to respond to changing g requirements for professional employment in computer science.
            It is the responsibility of the student to understand and fulfill polytechnic, and  Department requirements. These requirements are described is the polytechnic has gone a ling way to keep those individuals (computer operators) in various way:
            i.          To acquire formal education in computer                               science
            ii          To register fully as members in Nigeria                                              computer society.  
Iii         to reduce non-professionals in the field.
            Computer is an electronic device, which is capable of receiving, sorting and retrieving information with tremendous speed, if computer is effectively used, it can help teachers teach computer science students visually in all the computer courses.
            This study based  on the  assessment of the methods of teaching computer courses to computer science major in selected Nigerian Polytechnics is trying  to find out those teaching methods use in teaching computers courses.
            According to McCathy (1989) common teaching methods are lecture method, lecture with Discussion, panel of experts, Brainstorming, video tapes, class Discussion, case studies, Role playing, Report-Back sessions, worksheets/surveys, index card exercise, Guest speaker, values clarification exercise.
            IPSJ Journal (2001), state that the method of teaching computer science in a department of liberal Art is from technique (concretion) to theory (abstraction), of from practices to lecture.
            In a physical classroom these is a standard, set of equipment and tools, this usually includes audio-visual equipment such as textbook, a chalkboard, video-visual  video player and tape recorder.
1.2              AIMS AND OBJECTIVES OF THE STUDY
            The aims and objectives of the study are to assess the methods of teaching computer courses to computer science major in selected Nigeria polytechnics.
1.         It investigated whether textbooks and chalkboard the          only teaching and learning tools in teaching computer         courses.
2.         It investigated whether multimedia instructional aids            are used for both teaching and learning in computer         science courses.
3.         It investigated whether E-learning is used in teaching           introduction to computers.
4.         To investigate the most common teaching methods   for computer courses to computer science majors.
