AN
ASSESSMENT OF METHODS OF TEACHING COMPUTER COURSES TO COMPUTER SCIENCE STUDENTS
IN SELECTED NIGERIAN POLYTECHNICS
ABSTRACT
The study
focuses on the methods of teaching computer courses to computer science major
in selected Nigeria polytechnics.
It examines
the background, methods of teaching, tools and equipments use in teaching
computer courses to computer science major. The primary data for the study were
generated from well structured question broadcasted to random samples of 70 out
of 200 NDII students from federal polytechnic Nekede and Abia State Polytechnic
and supported with interviews. Frequency labels, simple proportion percentage
ratios, average, ranking, and chi-square (test for goodness of fit) for
validation of the some of the some of the findings as distributed.
From the
data presented and analyzed textbook is the mostly used tool for teaching computer courses to computer science
major.
Followed by
the computer but 20% students said that textbooks, chalkboard and computer are
the tools used.
It was also
established from the study that lecture method, lecture with discussion
practical assignment, and class
discussions are the methods of teaching
computer courses to computer science major.
Therefore
the researcher summarized and recommend that the NBTE (National Biand for
Technical Education) should improve on the
teaching tools by providing enough computers for teaching and learning
and the methods of teaching computer
courses to computer science major should be maintained and if possible across other departments.
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.
1.3 STATEMENT OF PROBLEMS
The objective of teaching computer
courses in Nigeria Polytechnics include to equip students with the necessary
knowledge that will aid them to identify those problems that can be solved by
means of computer system, and to design and implement effectively.
Another objective of the study is to
provide the intellectual foundation for future professional development. A
cornerstone in this study is ability fro student to reason logical. It is
essential that student should be familiar with basic concepts in many computer
courses.
Although, there are some other
problems such as:
- Lack of lecturers to teach
computer courses.
- Lack of teaching tools
- Lack of application of
computer to real world situation in their programme of study.
- Extreme abnormal dislike or fear
and dread of mathematics (one of the
credit required for one to study
computer science).
1.4 PURPOSE OF THE STUDY
The purpose
of the study is to the methods of
teaching computer courses to computer science major.
Also to
educate student to succeed in his/her professional career, which takes place in
the context of rapidly changing technology. In order to succeed in this area,
the student must have certain knowledge, skills and attitudes.
1.5 RESEARCH QUESTION
The
objective of the research is to determine those tools/ methods that are used in
teaching computer science major in Federal Polytechnic Nekede and Abia
State Polytechnic.
In order to
conduct an effective study on the central theme of this work, the following
critical questions have been addressed namely:
(a) What are the tools used in
teaching computer courses?
(b) Is your polytechnic connected via
Internet?
(c) How effective is the use of
computer on the teaching and
(d) What are the most common teaching
methods of computer courses e.g. Introduction to computer, computer packages,
Computer Programming, and, Computer Hardware maintenance.
1.6 SIGNIFICANCE OF THE STUDY
Information
technology (IT) is providing for the use of computer aided (CAL) systems to
assist in the Education and training of students.
This study
will assist computer science students to know teaching methods both old and
new. It will help them to understand that developments in computer science will
make new applications profitable and new method viable.
1.7 SCOPE OF THE STUDY
The study is targeted at Federal
polytechnic Nekede Owerri, Imo State and Abia State Polytechnic it covers all
phases used in teaching computer courses. The wing topics will be addressed:
- Introduction to computer
- Computer packages
- Computer Programming
- Computer Hardware
Maintenance
1.8 LIMITATIONS OF THE STUDY
The
researcher encountered a lot of problems such as limited time provided for this
study.
Furthermore,
the researcher encountered the problem of limited number of respondents since
some of the respondents have not filled questionnaire of this type
before.
