BIOLOGY PROJECT: FACTORS THAT MILLITATING AGAINST EFFECTIVE TEACHING OF BIOLOGY IN SECONDARY SCHOOLS
CHAPTER ONE
BACKGROUND
TO THE STUDY
The
term science has to do with nature; it is derived from the latin word scientia
which means knowledge.
It is a systematic enterprise that builds and organizes
knowledge in the form of testable explanation and predictions about the
universe. It can equally be defined as the field of study which tries to
describe and understand the nature of the universe in whole or part. According
to Hyacinth (2004) science in its broadest scene refers to all human activities
involving organized knowledge of natural phenomena. It also refers to a system
of acquiring knowledge here system uses observation and experimentation to
describe and explain natural phenomena.
According
to hornby (2002) science is the knowledge about the structure and behavior of
natural and physical world based on facts that can be proved. Science is the
study of natural phenomena and is distinguished from other fields because it
relies on the hypothetical, deductive and experimental approach. Webster’s New
collegisted Dictionary defined science as the knowledge attained through study
or practice, in order word it is a knowledge covering general truths of the
operation of general laws, especially as obtained and tested through scientific
method and concerned with the physical world.Mbajorgu (2003),Ali(2000)perceives
that science is concerned with regards to developing, acquiring and controlling
knowledge, skills, capacity and attitude about natural factors of the
environment. Science according to Onah (2003)
is the bedrock upon which any nation can be built. It is said to be a very
important of man’s life so much that its role in societal development has been
revealed by various civilizations world-wide. Science increasingly associated
with the scientific method itself as a disciplined way to study the natural
world including physics, chemistry, geology and biology.
No country can be
globally recognized without talking about its scientific advancements. This can
be seen in all aspects of life such as medicine, engineering, industries, education
etc.
Science
education has been recognized world-wide as a pre-requisite in science and
technological development. It is that education intended to make every
individual scientifically literate enough to like in this age of science and
technology, and to have those with the intellectual ability productive and
functional members of the society, through training in science based
professions or vocations, Hyacienth(2004). Science education encourages
students to think and act as responsible scientist by providing opportunities
for them to acquire knowledge and understanding of relevant concepts.
According to Hyacienth(2004),science education is
field of study specifically concerned with two basic aims which are as follows
1. The production of a
scientifically interaction society.
2. The development of potential
scientific and technological manpower.
Maduabum
and Azuezuilo(1980), reveals that education through study of science produces
economic benefits and contributes to a country’s future wealth by increasing
the productive capacity of its people.
Science is a great enterprise which
technologically science therefore is receiving much emphasis in education
because of its significant and relevance to life and society.
The
term biology is derived from two Greek words “bios” and “logos” which mean life
and study respectively. Biology therefore means the study of life or study of
living things. According to stone etal (1985), biology as a science is defined
as a scientific study of living organisms. It is therefore a natural science
concerned with the study of life and living organisms, including their
structure, function, growth, origin, evolution and taxonomy. It have several
branches; including the two big branches of biology which are botany (the study
of plants) and zoology (the study of animals), morphology (the study if
external structure of living things) physiology (the study of how living things
function), Ecology (the study of relationship between living things and their
environments), Genetics (the study of how living things inherits characters
from their parents) Cell biology (the study of cell structure and functions).
According
to Okeke (2000). Students who did well in biology could have prospects of becoming:
Doctors, Nurses, Pharmacists, Dentists, Biology teachers, Medical technologist,
Food technologists, Genetic Engineers, Microbiologists, Biochemists, and other
science subject.
Biology
has its origin from Europe but today all the nations of the world accord
priority attention to science and technology in development efforts. The reason
for according such priority attention to science and technology being that it
carries the promises of great economic improvement and equally serve as a gateway
to national development in the age of fast developing technology, has become
necessary for all countries of the world especially the developing ones to
organize and improve the teaching of science throughout the school stage. It is
through science that we get the fundamental bases to develop technology.
Biology
often overlaps with other sciences, for example biochemistry with biology and
chemistry, Astrobiology with biology and astronomy. Social science such as
geography, philosophy, psychology and sociology can also interact with biology,
for example in administration of biological resources, developmental biology
etc. it is a vast subject containing many subdivisions topics which are five
unifying principle that can be said to be fundamental of modern biology.
1. Cells
are the basic unit of life
2. Living
Organisms consumes and transforms energy
3.
Organisms regulate the internal environment to maintain a suitable and constant
condition.
4. Genes
and the basic unit of heredity
5. New
species and inherited characters are the product of evolution.
Sub-discipline
of biology are recognized on the basis of the scale at which organisms are
studied and methods used to study them, Biochemistry examines the rudimentary
chemistry of life, molecular biology studies the complex interactions systems
of biological molecules; then cellular biology examines the basic building
block of all life, which is the cell, physiology examines the physical and
chemical functions of the tissue, organs, organ of facts and presentation of
information about the natural world. The pace of the development of a given
country is always determined by the type of education which operates in that
country. What is needed in biology is students involvement in the exploration
of important ideas of biology.
Effective
teaching of biology is a process by which a biology teacher adopt all the
possible method used in teaching in the classroom to make sure that students
understand biology and be able to respond positively during assessment or to
produce a good result.
Teachers’ effectiveness is exhibited in the teaching
method, classroom managements, the material as well as the way students are
being handled, a good teacher always bear in mind the individual differences of
the students while presenting the lesson and frequently check the student’s
understanding of his or her points to make sure that they are getting of
understanding his lesson. This also includes the ability of the teacher to
answer question asked by the students, having knowledge about his or her
subject matter and ability to show students how to conduct appropriate
research.
Effective
teaching is crucial, in order for students to reach educational success in and
outside classroom setting, therefore, there has been some factors militating
against effective teaching of biology in senior secondary school in Nsukka
Local Government Area, which some of them are as follows:
1.
Unqualified biology teacher: Inappropriate training background of science
teachers especially biology teachers and qualification of biology teachers are
the major factor that militate against effective teaching of biology because
some biology teachers in some senior secondary school did not undergo enough
training to enable them get skills, qualities and enough knowledge of the
subject matter and how to impact the knowledge to the students.
2. Poor
method of teaching biology in senior secondary school: For teaching to be
effectives one must use different methods of teaching. According to Eke (2001),
teaching is effective if only it produces or yields the desired results, the
ability of the teacher to adapt to different situations and produce a desired
result in the classroom is a mark of teaching effectiveness. Vennier and Faith
(2001) are of the opinion that all the teaching activities are supposed to
produce learning, so that test of effective teaching will be amount of learning
that occurs.
When
the following methods are used, teaching of biology can be effective. According
to Bigmen (1999), activity method, inquiry method, and discovery method which
elicit student’s interests and enhance their level of attainment or
comprehension of biology. Activity method the methods that encourage students
to participate actively during the lesion while teaching at the same time.
Oforkansi (2008) defined activity method as a method whereby the students learn
through active involvement rather than being passive or being at the receiving
end.
According
to Ofokansi (2008), discovery means finding out. Exploration, manipulation and
experimentation are components scientific enquiry that help one to discover.
This approach demand that the teacher create the problem and allow the
pupil/students to find answer for themselves. The author also said that enquiry
involve active participation by the student/pupil rather than transmit a
preconceived notion about situations.
3.Inadequte
supply of biology equipment: In some schools, many laboratories equipments like
microscope, glass tube, Beaker, slide, Bones of vertebrates etc. charts of
different animals development, systems, organs, etc, work book for practical
and textbooks are not adequate for the students in learning of biology. Biology
is a science subject which is all about practical and also when combined with
other science subject one will be able to study courses like medicine, nursing,
pharmacy etc in higher institution. Beaty and Woolnough (1990) are of the
opinion that the obsolete and insufficient teaching of biology in senior secondary
schools. They stressed that the teacher may be competent enough and have all
the qualities to impact the knowledge to the students but to the obsolete and
insufficient availability of biological equipment the aim is defeated.
Teachers
attitude towards the teaching of biology: the teachers personalities such as
the way the teacher walks, talks, reacts to issues, his/her code of conduct and
dressing code has become the major factors which leads to the ineffective
teaching of biology. It goes with the saying that the personality of such
teacher affect the effective teaching of biology in a great way. Enwieme(2001)
continuous to stressed that teachers personality invariably affect the
effectiveness of teaching of biology. Oforkansi(2008)opinion that personal
qualities do not only enhance teaching and learning but also promotes the tone
of the school as well as the profession.
In
summary, ineffective of teaching of biology in Nuskka Local Government Area
could be due to the several reasons such as classroom management,
communication, teachers qualification, supply of biology equipment, teachers
personality, negligence of seminars, and workshop by the teachers of biology,
inadequate illustration and practical aspect of biology is another factors,
infrastructural facilities and absences of laboratories etc.
1.2 STATEMENT OF THE PROBLEM
Biology
is one of the core science subjects, which is supposed to be the most
interesting subject to students in senior secondary schools. It has been
discovered that the effective teaching of biology has been very important. But
the rate at which students fails biology in result time’s shows that effective
learning has not been attained by these students. Aganga (2000) observed that
“Many secondary schools, especially the public schools have insufficient
competent teachers as well as biological equipment in their different schools”.
Therefore, there is the need to answer certain questions to re-enforce their
effectiveness in teaching.
1.3 PURPOSE OF STUDY

secondary schools in Nsukka Local Government Area have qualified biology
teachers.
2. The method of teaching adopted by
teachers in teaching biology in Nsukka Local Government Area.
3. The extent to which senior
secondary schools in Nsukka Local Government have adequate supply of biology
equipment.
4. The extent to which teachers
attitude affect the teaching of biology in Nsukka Local Government Area.
1.4 RESEARCH QUESTIONS

According
to PPSMB, there are thirty (30) secondary schools in Nsukka Local Government
Area and the study will cover all the biology teachers in senior secondary
schools in Nsukka Local Government Area.
1.7 DEFINITION OF THE BASIC CONCEPTS
Factors:
Are one of the element contributing to a particular result or situation.
Militate
against: This is a process of making something less likely to happen or
succeed. According to Oxford Advanced Learner’s dictionary militate against is
to prevent something or to make it difficult for something to happen or exist.
Teaching:
this means to impart knowledge to or to instruct someone as to do something.
Okonkwo (2005) in Oforkansi (2008) defined teaching as a deliberate effort by a
mature or experienced person to impart information, knowledge, values skills,
norms (standard behavior) more (moral values) attitude language and so on to an
immature or less experienced person through the process that is morally and
pedagogically acceptable.
Effective
teaching: is a process by which a teacher adopt all the possible skills or
method used in teaching in the classroom to make sure that students understand
the lesson and be able to respond positively during evaluation and produce a
good result.
Biology:
Biology is the study of life and living things. It is also a natural science
concerned with the study of life and living organisms including their
structure, function, growth, evolution distribution and taxonomy.
Senior
secondary school: This is a period of study from senior secondary school one to
senior secondary school three.
