CHAPTER ONE

INTRODUCTION

Background to the Study

Formal Education was introduced into our country (Nigeria), by the white Missionaries in 1842 Baja in Omiko (1987). At this period, the curriculum emphasized three main things; Reading, writing and Arithmetic. Survey studies carried out by Taiwo (1975), Abdullahi (1982) and Ukpai (1985), showed that teaching and learning of science in Nigerian schools started as far back as 1878. According to them, science was taught as general science to classes one and two in the secondary schools and as biology, chemistry and physics to upper classes of three, four and five. However, according to the Science Teachers Association of Nigeria (STAN 1970) in Omiko (2015), this general science continued until 1970 when Integrated Science, now Basic Science, was introduced as a base to express the fundamental unity of scientific thought. The teaching and learning of integrated science replaced the general science and was taught in Nigerian schools up to 1980 when the Federal Government restructured the 5-years secondary school system into 6-3-3-4 system. That is 6 years primary Education, 3-years junior secondary school (JSS) Education, 3-years Senior Secondary School (SSS) Education and 4-years tertiary education (FRN, 1981). The teaching and learning of integrated science in Nigerian schools especially at the Junior Secondary school level continued till 2009 when the Federal Government of Nigeria restructured the 6-year secondary school system into 9-3-4 system. The reform Agenda in Education in Nigeria brought a change in integrated science both in content and name. The content was broadened and the name changed from integrated science to basic science. Oka (2015) and Nwafor (2012) observed that basic science formally known as integrated science is a subject taught at both public and private schools at the Junior Secondary school level. Basic Science is an introductory course to the study of the sciences in the senior secondary school. The definition of integrated science (Basic Science) as was given by UNESCO (1973), and Omiko (2005) is a science in which concepts and principles are presented so as to express the fundamental unit of scientific taught and avoiding premature or undue stress on the distinction between various scientific fields. Ukpabi (1985) in Omiko (2005) defined Basic Science as a science in undifferentiated form which stresses the fundamental unity of science. Basic science involves the study of elementary biology, anatomy, earth/solar system, ecology, genetics, chemistry and physics as a single science subject in the Junior Secondary school. It offers the basic training in scientific skills required for human survival, sustainable development and societal transformation. Basic science studies also involve bringing together traditionally separate science subjects so that students grasp a more authentic understanding of science.

The alarming rate of poor performance in science subjects coupled with the low educational standard in the country are parts of the major reasons why most students shy away from the study of science. This negative attitude has encouraged poor performance and low participation of students in the higher science subjects like physics, chemistry and biology. All these problems mentioned above have been conclusively blamed on basic science and its teaching. Basic science serves as foundation for meaningful understanding of advanced scientific theories and principles because the bulk of content of the basic science curricular is descriptive, where the student is meant to learn many basic concepts like energy, matter, force and measurement. Previous studies have revealed that science teaching has been facing problems from different angles ranging from the learner, the teacher, the school, the government and even the parents.

The study of Basic science (Integrated science) is a new way of studying science, according to Omiko (2012) and Anaekwe et al (2010), Basic Science was introduced into this country Nigeria a few decades ago. It started with few schools, and now all the junior secondary schools in the country have adopted it. According to the National Policy on Education (FRN, 2004) the aims of Basic Science (Formerly Integrated Science) should be directed at enabling students who are exposed in it, to acquire the following skills:

1.     Observe carefully and thoroughly

2.    Report completely and accurately what is observed.

3.     Organise information acquired

4.    Generalizing on the basis of the acquired information

5.    Predicting as a result of the generalization

6.    Designing experiments (including control where necessary) to check predictions.

7.    Using models to explain phenomena where appropriate; and

8.    Continuing the process of inquiry when new data do not conform to predictions.

To achieve these objectives, it is suggested that the teaching and learning of Basic science should involve the use of innovative methods of teaching like discovery, problem-solving, open-ended field trips and laboratory methods and among others. Omebe and Omiko (2015) observed that these suggested methods of teaching Basic science have been utilized for several years by the integrated science teachers and yet the results of the students in the Junior Secondary School Certificate Examination (JSSCE) has not been encouraging. This status may be attributed to lack of trained teachers, lack of proper teaching materials, absence of conducive teaching and learning environment, inadequate evaluation or probably, inadequate teaching methods.

Idoko (2008) revealed that unprofessional and inexperienced basic science teachers using inappropriate teaching methods in conveying practical skills to students are responsible for lack of interest and poor performance of students in basic science practical. This indicates that teacher qualification and nature of skills in conveying practical skills among the factors affecting performance of students in basic science.

Instructional materials are essential and significant tools needed for teaching and learning of basic science to promote teacher’s efficiency and improve students’ performance in basic science. Instructional materials make learning more interesting, practical, realistic and appealing. They also enable both the teachers and students participate actively and effectively in lesson sessions. Ibeneme (2000) defined teaching aids as those materials used for practical demonstration in the classroom situation by students and teachers. However, this study will assess the effect of teachers’ qualification and instructional materials on Basic science students’ academic performance in Ukwuani LGA of Delta State.

Statement of the Problem

It is surprising that despite the efforts of Delta  State  government,  to  improve the  standard  of  education  by providing the required human and material resources for the implementation of education at all levels, students’ performance  in  basic science in  internal  and external examination  is very poor in recent years. This situation makes one to wonder what could be the causes of this persistent failure of students in basic science examination. Some scholars attributed this  high  failure  rate  in  science and  basic  science  to  various  factors  which could  be institutional  and  non-  institutional.  In support Okolie, Elom and Inyiagu (2014), observed that poor performance of students in basic science has been so high in many Nigerian public schools in the recent years due to the unavailability of qualified basic science teachers. If this is not checkmated, our Science and Technology related subject graduates from the post-primary schools may not be employable and those who may further in their University Education may experience difficulties because of their background. Consequently, our educational system will not attain its objective of producing qualified and competent product in science education.

The problem which this study intends to solve: what then is the effect of teachers’ qualification and instructional materials on Basic science students’ academic performance in Ukwuani LGA of Delta State?

Research Questions

The following research questions have been raised to guide the study;

1.    Is there any relationship between teachers’ qualification/experience and students’ performance in basic Science?

2.    Is there any relationship between laboratory facilities and the effective teaching and learning of basic science?

3.    Is there a relationship between teacher’s method of teaching Basic Science and students’ performance?

4.    Is there any relationship between teachers’ gender in teaching Basic Science?

Research Hypotheses

1.    There is no significant relationship between teachers’ qualification/experience and students’ performance in basic science.

2.    There is no significant relationship between laboratory facilities and the effective teaching and learning of basic science.

3.    There is no significant relationship between teachers’ teaching method and students’ performance in basic science.

4.    There is no significant relationship between teachers’ gender in the teaching of basic science and students’ performance.

Purpose of the study

The main purpose of this study is the effect of teachers’ qualification and instructional materials on Basic science students’ academic performance in Ukwuani LGA of Delta State. However, the specific purpose of this study is stated as follows;

1.    To investigate the relationship between teachers’ qualification/experience and students’ performance in Basic Science.

2.    To find out the relationship between laboratory facilities and the effective teaching and learning of basic science.

3.    To ascertain the relationship between teacher’s style of teaching Basic Science and students’ performance.

4.    To identify the relationship between teachers’ gender in teaching Basic Science and students’ performance in the subject.

Significance of the study

The result of this research will be beneficial to the following; students, teachers, educational administrators, curriculum planners and future researchers.

The outcome of this study will enable the students to understand the influence of teachers’ qualification, experience, techniques, and method of teaching and equipment for teaching and learning of basic science.

However, basic science teachers will be armed with the requisite information about the various factors that influence students’ academic performance and foster ways to enhance students’ interest in the teaching and learning process. Also to improvised adequate teaching and learning equipment for the effective teaching and learning of basic science.

Again, findings from this study maybe of uttermost importance to educational and curriculum planners because it would act as a feedback or evaluation to the curriculum implemented, to ascertain if the required experience, expertise, qualification stated for entry into secondary teaching, meets the educational needs of the learners, to make further prescription or better analyze the effects of teachers attitudes on students’ academic performance.

Lastly, it will be of great importance to future researchers who would seek reference on recent literature review and to give an up to date analysis on the basic science teacher qualification and equipment for teaching and learning of basic science.

Scopes and Delimitation of the study

The study will cover the effect of teachers’ qualification and instructional materials on Basic science student’s academic performance in Ukwuani LGA of Delta State. The study is limited to five (5) selected secondary schools in Local Government Area of Delta State.
