CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Science, from its linguistic origin was derived from the Latin word "Scientia"
which means "Knowledge" (Eneh, 2000). Science as a branch of knowledge is the
systematic study of things around us. The totality of Knowledge obtained from such
studies constitutes scientific knowledge. In addition, science deals with nature, by
observing it and later to experimental investigation (Agbo, 2007 & Kalu, 2007).
In science education, students are exposed to several methods and strategies of
teaching and learning of science. These include lecture method, demonstration method,
discovery method, discussion method, laboratory activities, co-operative learning etc.,
depending on the aspect one wants to teach.
Biology as a branch of the general body of knowledge (science), has been defined
by different scientists according to perception and understanding of the subject. (Okwo,
2008 and Tawtiyas, 2009) define biology as a science which involves systematic study of
living things interaction with each other and their environment. Biology deals with the
study of life (Uchenna and Okafor, 2012). Hence it is one of the courses of study in
science education curriculum and a core subject in senior secondary schools in Nigeria.
Biology as a science of life is concerned with the characteristics of living things, their
forms, functions and relationship with one another and with their environment among
others.
However, for effective biology teaching, the use of method/strategy which would
make the use of the environment would achieve more and bring home the actual meaning
of the concepts. Among science subjects (chemistry, physics and biology), biology is the
most popular (Ibrahim, 2008). It is a core (compulsory) subject for almost all Senior
Secondary Schools Students in Nigeria. Also, the basic knowledge of biology is a
prerequisite for studying a number of disciplines such as Medicine, Agriculture,
Pharmacy, Microbiology, Biochemistry and Psychology among others (Bichi, 2003, Kalu
& Ndokwo, 2006). So, the use of strategy that will improve the achievements and
interests of the students in biology should be used. Biology plays a vital role in the
economic development of a nation. This is because Ajaja, (2008) said that recent
advances recorded in the field of biochemistry, physiology, ecology, genetics and
molecular biology, have made the subject a central focus in most human activities
including solutions to the problem of food scarcity, pollution, population explosion,
radiation, disease, health, hygiene, family life, poverty eradication, management and
conservation of natural resources as well as biotechnology and ethics.
Due to immense benefits of the subject (Biology) to both individual and societal
development, the Federal Government of Nigeria, in the National policy on education,
(FME, 2013). The objectives of biology include;
a. Adequate laboratory and field skills in Biology;
b. Meaningful and relevant knowledge in biology;
c. Ability to apply scientific knowledge to everyday life in matters of personal and
community health and Agriculture;
d. Reasonable functional scientific attitudes and
e. Emphasis of content and context of the syllabus is placed on: field studies,
guided- discovery/Biology as inquiry (FME, 2013).
Thus, from the objectives, an outdoor strategy such as field-trip has been
recommended by FME for its implementation for the accomplishment of biology
objectives in the secondary schools in Nigeria. However, despite the recommendation on
field-trip as a strategy for teaching biology, many biology teachers in the various
secondary schools still teach biology concepts using only the traditional method i.e.
lecture method (Usman, 2000).
There are different concepts of biology and there are different ways of dealing with
them effectively. For instance, there is anatomy and physiology, genetics, evolution,
nervous co-ordination, among others, much of which can be taught effectively by
demonstration, discovery, lecture method, activities based in the class room and/or indoor
laboratory. There is an aspect in biology that is referred to as ecology that requires
students to be taken out to see living organisms in their natural habitats. This strategy is
called field-trip.
A field-trip is taking students outside the classroom for the purpose of making
relevant observations and also obtaining some specific information. It could be in a
nearby school farm, national park, zoo, forest, industry or game reserve. It is an
important component of science teaching Bajah, (2008). According to Obeka, (2009);
Field-trip is an outdoor type of laboratory activity or field work or learning exercise
undertaken by teachers and students in certain aspects of a subject, to give students the
opportunity to acquire knowledge.
However, field-trip is not the only method/strategy for effective teaching and
learning of concepts in biology which can gear towards the training of the individual
through child-centered learning for maximum self and societal development. There are
some strategies like problem solving, inquiry, questioning teaching strategy, discovery
approach, concept mapping etc. All these approaches could be used for teaching different
concepts to make learning more effective, meaningful and relevant in biology. However,
these approaches cannot be effectively used in the teaching and learning of ecology
concept.
However, some biology teachers do not discriminate, in the method they use in
teaching. They teach all aspects of biology by lecture method (Okafor, 2008), this may be
one reason for poor performance of students in this subject (Biology), It is high time
teachers of science began to vary in the methods/strategies they use to teach the different
aspects of science for effective measures, so that students would be able to learn more,
retain more, and apply what is learnt by engaging in significant activities. It is on the
basis of improving students learning in biology, that the study focuses on field-trip
teaching strategy particularly for ecology concept which may help the students to partake
fully in set out activities.
Lecture method is the teacher-centered method, which is seen as the traditional
chalk and talk method of teaching where the teacher does the talking while students serve
as receivers only by listening and taking down notes. Obeka, (2009) described lecture
method as a teacher-centered method. It further said that the method comprises the
acquisition of subject matter usually by memorization and close supervision of the
students by the teacher. However, lecture method does not require the use of basic
science skills (observation, identification, classification and manipulation of substances
in their natural environment). Therefore, it cannot be used effectively in teaching and
learning of ecology concept in biology. Instead, field-trip teaching strategy alongside
lecture method of teaching may serve to improve students’ academic achievement.
Teaching strategy, therefore, is simply defined as a process-oriented model that
allows teachers to present ideas and concepts at many different levels to meet the needs
of a variety of learners (Bloom, 2007), stated that field-trip falls under the category of
teaching strategy because of the high potential for hands-on learning for the participants.
It is also seen as a fun day away from school. The students are able to see the concepts
learned in class work in the real world through direct observation of organisms in their
natural environment by the process known as field-trip. This study investigated the effect
of field-trip teaching strategy on students’ academic achievement in biology.
Academic achievement is based on the degree of intellectual stimulation that a child
could receive from a learning situation, (Obeka, 2009). According to Blaiv, (2010), to
achieve is to accomplish or gain by effort or do something successful with an effort and
skill.' Okafor, (2011) on the other hand maintained that academic achievement concerns
with mental health care. According to him, mental health has its basis, physical health,
and intellectual skills which lead to satisfactory means of adjustment, social sensitivity
and adequate self-concept. Scientist such as Okafor, (2011) and Kalu (2013); are
therefore, concerned with how to improve the students’ academic achievement and
interest level in science particularly biology.
Another variable which can be affected by teaching method is the students’ interest
in ecology concepts. An interest is a subjective attitude motivating a person to perform a
certain task. It affords pleasure and satisfaction. It results in curiosity towards the object
of interest, enthusiasm to be attached to the object, strength of will to face difficulties
while engaged in the task of one’s interest, a definite change in behavior in the presence
of the object characterized by attention and concentration.
Interest is a powerful motivational process that energizes learning, guides academic
and career trajectories, and is essential to academic success. Promoting interest can
contribute to a more engaged, motivated, learning experience for students (Renninger &
Hidi, 2016). Student interest is essential to academic success.
Jones states, “Interest is a feeling of likening associated with a reaction, either actual or
imagined to a specific thing or situation.
Jones, (2010), mentions two distinct types of interests which are extrinsic and intrinsic.
The former are pleasurable emotions connected with a purpose or goal of an activity. It
may involve fame, name, money, victory or such external motives of conduct.
1.2 Statement of the Problem
The performance of students in biology at the senior secondary school level of
education in Nigeria has been persistently poor over the years (West Africa Examination
Council WAEC, 2011; 2012; 2013; 2014 & 2015). The problem has been linked to poor
teaching strategies (Nwagbo, 2010; Abiodun, 2012). The poor teaching strategies
employed by educators may have caused students to lose interest in the subject (Ogbonna
& Odike, 2014). If this problem persists, students’ interest in biology will deteriorate
further and the country’s standard in science education as well as the economy will be
immensely affected. This is because biology is a pre-requisite subject for many fields of
development including medicine, surgery, pharmacy, forestry, biochemistry, among
others. The country will therefore not be able to produce sufficient number of doctors,
dentists, pharmacists, and other scientists to meet the demand of the country’s skilled
manpower needed for scientific and technological development.
Whereas, the search for more effective approach for the teaching and learning of
biology that will enhance students’ interest and improve their performance has been on for
some time now, that search is yet to end. Needful to say that for a nation to advance,
appropriate measures have to be put in place to improve students’ level of interest and
achievement in science subjects, especially biology. Therefore, this study investigated the
effects of field-trip teaching strategy on academic achievement and interest among SS1
biology students in Ecology.
1.3 Aim and Objectives of the Study
The main purpose of the study was to determine the effects of field-trip teaching
strategy on the interests and achievements of SS1 (One) biology students in ecology in Jos
North Local Government Area, Plateau State.
Specifically, the study intends to:
1. To determine the significant difference in the mean interest score between students taught
using field trip and those taught using lecture method.
2. To determine the significant difference in the mean achievement score of ecological concepts
between those taught using field trip and those taught using lecture method.
3. To determine the significant difference between the treatment and control of male and female
students’ interest in ecology.
1.4 Research Questions
The following research questions are set to guide the study;
1. What is the general interest of students in biology?
2. What is the achievement profile of students in ecological concepts?
3. What are the mean interest scores of students taught ecology using field trip instructional
strategy and the conventional method?
1.5 Hypotheses
This study has the following null hypotheses and will be tested at 0.05 level of
significance.
1. There is no significant difference in the mean interest score between students taught using
field trip and those taught using lecture method.
2. There is no significant difference in the mean achievement score of ecological concepts
between the ss1 (one) students taught using field trip and those taught using lecture method.
3. The mean deferential between the treatment and control of male and female students’
interest in ecology is not significant.
1.6 Significance of the Study,
The study will be beneficial to, Students, Teachers, School management, Curriculum
planners, and researchers.
It will also encourage active participation of the students which will help in meaningful
teaching and learning, help in minimizing the high failure rate of secondary school
students in biology. Serve, as a foundation for further research studies on field-trip,
particularly in teaching other science courses. Help the teacher to effectively teach
ecology concept in senior secondary school so as to minimize the failure rate of final year
Biology students.
It also helps the curriculum planners in designing ecological concept toward field work
and also help serve as an encouragement for teachers to use field-trip for difficult concepts
in science. Encourage parents to pay for their children & wards to go on field-trips. The
research findings will be used to make some improvements on the way students interact
among themselves and their understanding of ecology, Meaningful interactive skills and
learning concepts will promote creativity, scientific literacy, and advancement in scientific
knowledge in students. The result of field-trip teaching strategy will provide purposeful,
efficient, and effective teaching and learning.
1.8 Scope of the Study
