IMPACT OF LESSON PLAN ON THE TEACHING AND LEARNING OF BIOLOGY IN SECONDARY SCHOOLS

1.1 Introduction

A lesson plan can be regarded as a well thought-out, orderly and sequential arrangement of the lesson on paper (National Teachers’ Institute, 2006). It is the guideline by which the teacher teaches his lesson. To teach successfully, the teacher must begin to plan days, weeks, or even months ahead of the time for teaching the lesson. These plans vary widely in the style and degree of specificity. Some teachers prefer to construct elaborate detailed lesson plans while others construct a sketchy form of lesson plan. In whatever way it may be written, it should be designed in such a way that it contains adequate information for the teacher to remind him of all the aspects that must be treated in any lesson. When lesson plan is transcribed into a note-book it becomes a lesson note (NTI 2006).

As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitations of the Study and Definition of technical terms.

1.2 Background of Study

The teaching of science in general and Biology, in particular, required the active participation of students in the teaching-learning process, to enable students to connect scientific concepts and theories to real purposes and practices in the world in which they live (Dumela,.& Bree, 2016). Unfortunately, the majority of the teachers teach Biology without engaging the learner actively during the teaching-learning process. (Okoli & Azubuike, 2012: Ibe, 2015). Students’ poor performance in external examinations could be as a result of poor teaching strategies and neglecting of students’ learning styles. However, different teaching strategies have been introduced but could not improve the achievement of students in Biology.

Teaching and planning are different ways employed by a teacher to impart knowledge to the learners. It is also disheartening to note that, in spite of the much focus on teaching strategies in science, students’ performance in science subjects particularly Biology have continued to record a persistent and depressing downward trend ((Ikitde, & Edet, 2013: Okoli &Azubuike, 2012). Several factors have been identified as affecting students’ achievement, these factors include inadequate laboratory equipment, inadequate science teachers, lack of science textbooks, poor teaching strategies amongst others but the neglected variables is learning the style. It is believed that effective learning takes place when the interactive process is one that is best suited to the individual students in terms of learning styles (Ikitde, & Edet, (2013).

Biology as one of the science subject is defined as the study of life and structure of living things. Biology is the study of living things and concerns itself with the study of the structure, behaviour, distribution, the origin of plants and animals and their relationship with their environments. Abugu (2007) stated that biology is a natural science in which we study living organisms – plants and animals. Furthermore Iloeje (1981) viewed Biology as the science in which we study living things. Based on the above statement, man lives in a novel world, there are animals, plants, rivers, oceans, deserts, mountains, and so on, all round him. Being a curious being, man takes delight in exploring his world, the seeks to have a world view of the universe, the strives to investigate all matter around him – their origin, nature, characteristics and other features, the inquires in his inquiry, he asks a lot of questions and in his search for answers to such questions, he needs to be systematic and unbiased. To achieve his goal, he engages in experimentation and observation, which are fundamental to science. Like other science subjects, biology in secondary schools is composed of practical activities. In all the sciences, biology geared towards simplifying theoretical content, so as to enhance effective instruction and learning of the subject. Allan, Rob and Jonathan (2000), stated the reason for emphasizing practical activities in biology like a realization of practical; work to be predecessor to real science knowledge. Practical work stimulates learner interest in the science subject they are studying, when they are made to personally engage in useful activities; knowledge obtained through practical; work and experience, promote long term memory that theory alone cannot do, from this reason, it becomes obvious that a learner acquired more in any science lesson, if giving the opportunity to do activities, ranging from manipulating apparatus, classifying, designing, experimenting, hypothesizing to maker inferences and verifying results. Hence, there is an urgent and serious need to justify the exposition of the students biology practical activates as well as studying its effect on student’s achievement in biology. Unfortunately, the ugly situation observed in the majority of our secondary school and students in lack of exposure of the students to practical activities. This contributes to persistent poor performances in biology.

In this study, the effect of individual students learning styles on achievement in Biology was investigated. However, theory of multiple intelligence suggests that there are a number of distinct forms of intelligence that each individual possesses in varying degrees. According to Howard Gardner (1995), the implication of theory is that teaching and learning should focus on the particular intelligence of each learner. For example, if an individual has strong spatial or musical intelligence, they should be encouraged to develop these abilities. Gardner (1995) points out that the different intelligence represents not only different content domains but also learning modalities/learning styles.

Therefore, in Ado-Ekiti, Ekiti State Nigeria where the research was carried out, the activities that was conducted is to know the Impact of Lesson Plan on the Teaching and Learning of Biology in Secondary Schools.

1.3 Statement of Problem

Investigation revealed that not much attention has been giving to the performance of the students in senior secondary school subjects most especially in biology and biology practical aspect of biology in schools has been blamed on such factors as the inability of the school authorities to provide materials and equipment for practical work, teachers failure to recognize the importance of practical work in science teaching.

According to Anidodoh (2001) in his study noted that a sound theoretical and practical knowledge of biology is needed for the management of our natural resources, provision of good health facilities, adequate food supply and favourable life environment. Thus, the teaching and learning of biology has to be encouraged in the schools. Moreover, this neglect, no doubt has relegated these subjects to the background in our senior secondary certificate examination. A close look at the 2008 – 2010 SSCE result records confirms that student’s performance has been very poor generally and particularly in biology practical, failure is a great problem as it will affect the students performances in science senior secondary school; that is why the researchers have decided to look into the cause and effects of biology practical;. This increasing number of dropouts in the area of the study is a clear pointer to theme.

In the light of the above, it should be a general concern of every Nigerian including the researchers to view this backwardness with some seriousness. There is great need to look into the issue of teaching and learning of the science subjects – biology etc. Biologists usually study are forms of life including ourselves, other animals, plants and microscopic living things such bacteria which is too small to see with our naked eyes. Biology is needed in medicine, nursing, pharmacy food technology etc
