MODELS UTILIZATION AND ACADEMIC PERFORMANCE OF BIOLOGY STUDENTS IN SECONDARY SCHOOLS IN NSIT ATAI LOCAL GOVERNMENT AREA
This study was carried out to investigate Models Utilization and Academic Performance of Biology Students in Secondary Schools in Nsit Atai Local Government Area. Two researcher hypotheses were formulated to guide the study. Quasi experimental research design was used for the study with the population of one thousand and nine (1009) Biology students from all the six public secondary schools in the study area. Data was obtained from one hundred (100) Biology study students from two schools using intact classes which formed the sample size of the study, while the two schools were selected using simple random sampling technique.
The instrument for data collection was Biology Achievement test, while the data collected were analyzed using independent t-test statistical tool. The findings revealed that students taught Biology with the used of models performed better than those taught without the use of models. It was also revealed that no significant difference exist between the academic performance of male and female students taught Biology with the used of model. Based on the findings of the study, it was recommended among others that Biology teachers should always utilized models when teaching topics in Biology in order to promote the academic performance of students.
Models Utilization and Academic Performance of Biology Students in Secondary Schools
1.1 Background to the Study
Teaching and learning processes are very crucial at all levels of educational development. If well planned and directed they are the keys to success and progress of individual materials have best methods couple with the right instructional materials have to be used in order to enhance effective teaching and learning models according to Dike (2009) do not only increase the motivation of the teachers and learners; they add clarity to the topic taught and make learning more interesting.
Permanent learning is the goal of education in that the learners should be able to retain what is taught and make learning more permanent since they appeal to more than one sense. Ode and Omokoro (2012) revealed that learners retain most of what they hear, see and feel than what they merely hear. This concept bears credence to the old chins adage which says ‘what I hear I forget what I see I remember and what I do I know (Arnett as cited in Claiborne and Drewery, 2013).
A visual instruction encourages the use of models to make abstract ideas more concrete to the learners. Therefore, the teacher’s duty is to make learning live, not just something to remember but put part of living experience. This can be done effectively by employing the use of models in teaching and learning of biology as a means of imparting knowledge to learners. Educators have come to realize that the most effective teaching and learning take place when an individual has direct experience with the subject under study, in order word, learners learn best by doing Agibe (2010).
A models is a representation of a system (for instance, the human respiratory system, thyroid, cardiovascular etc) or a phenomenon (such as the changing seasons, the oxidation of body, or human’s maintaining their body temperature etc). there representations can be the form of drawings, diagrams, simulation pr even physical replicas.
According to Okobia (2011), teachers frequently use models in the classroom, in fact, textbook are full of these representation: unfortunately, most teachers rarely make use of models. Models are used as props to show, point out, or provide examples of a system or phenomenon. Visual resources are books, charts, motion pictures, posters, diagrams, and photographs.
Models play a great role in clarifying nonverbal symbols and promote interaction among our students and their subject teachers. Mavida (2008) stated that, the utilization of models in the classroom make students participate effectively in the teaching process hence enhancing quality education that enables them to suit in the current society in relation to technological changes. Models used enhanced visual imagery, stimulates learning and assists the teacher to properly convey the topic content to the learner, to achieve better understanding and to perform well.
According to Mabel (2009) models are categorized into different types. Based on the degree of abstraction, models are grouped into symbolic and analogue symbolic models is the representation of the entities of a system through symbols. This model includes Biological and conceptual models. Symbolic models is the most abstract among the three categories of models. Some examples of symbolic models include, cyclical model, rainfall-runoff relationship model and regression model.
Analogue models is the next category of model which is the representation of entities of a system by analogue entities pertaining to the model. Analogue model can be built though two dimension visualization. For example, charts, graphs, maps and diagrams. It can also be built through three dimension visualization, for example, the flow of water in pipe to represent flow of blood in vein. The third category of model is the iconic model.
The importance of instructional resources to the successful implementation of the new Biology curriculum cannot be overemphasized. This is because the use of instructional resources such as model is a sineguanon for effective behavioural change in learners (Jimon, 2009). This is why Adekunle (2008) in Okibia (2011), noted that when students are given one opportunity to learn through more sense, they learn faster and easier.
Therionwn (2010) referred to models as objects or devices which help the teacher to make learning meaningful to the learner. They are materials used to assist the transference of information from one person to the another. In other words, models are learning materials. It offers a variety of learning experiences individually or in combination with different teaching and learning experiences as well as encourages learners to become skilled technicians with an endless passion for learning.
Okobia (2011) summarized the importance of using model on the classroom to include: making the subject matter more real; explicating difficult concepts, making the learners and preventing misconceptions. It is against this background that the study sought to find out the utilization of models and academic performance in Biology in Nsit Atai Local Government Area.
Models Utilization and Academic Performance of Biology Students in Secondary Schools
1.2 Statement of Problem
In spite of the accompanying gains and the clarion call for the provision and utilization of models facilities in the school system, in Nsit Atai Local Government Area of Akwa Ibom State there are still serous inhibiting factors encountered in the attempt to revolution Nigeria education. The current educational situation in Nigeria only portrays models in science related subjects and therefore not beneficial to other educational units. There are many challenges that hinder the process of using models in the classroom.
However, when effectively, used, models have a dramatic effect on teachers and learners. But, where models are not used effectively, they do not add value to teaching and learning. The problem of this study therefore is to find out how the prevision of models and utilization influence academic performance of students in Secondary Schools in Nsit Atai Local Government Area.
1.3 Purpose of the Study
The main purpose of this study was to examine models utilization and academic performance of Biology students in Secondary School in Nsit Atai Local Government Area.
Specially, the study aimed at;
- Examine the difference between the academic performance of Biology students taught with the use of models and those taught without the use of models in Secondary Schools in Nsit Atai Local Government Area.
- Examine the difference between the academic performance of male and female Biology students taught Biology with the use of models in Secondary Schools in Nist Atai Local Government Area.
1.4 Significance of the Study
The result of this study will be immense benefits to students, teachers, schools authorizes, educational stakeholders in the following ways.
- It will enhance the learning processes of the students and thereby improve on their overall academic achievement.
- It will increase the motivation of the students, add clarity to the topics taught and make learning more interesting.
- The study will help to sensitize teacher and staff of Secondary Schools who teach biology of the important roles in promoting the application of models in teaching and learning. This is because it will provide a basis for them to understand the need for their complimentary roles in encouraging and supporting the application of models aids.
- The will further help to reveal and create awareness among the school authorities of the importance or otherwise of the use of models in teaching and learning. This is because the findings from this study may require taking a decision by the secondary school authorities whether to refuse models use in learning curriculum or to modify expunge or discontinue with the existing teaching methods.
- It will help to create awareness for state and federal ministry of education as policy makers in secondary schools of the need to infuse the use of models as a core teaching instructional aid in the curricula of secondary schools and impress upon them to provide explicit strategy for enforcing the use of models materials in teaching and learning.
1.4 Research Hypotheses
The study was guided by the following research hypotheses
- There is no significant difference between the academic performance of students taught Biology with the use of models and those taught without the use of models in Secondary Schools in Nsit Atai Local Government Area.
- There is no significant difference between the academic performance of male and female students taught Biology with the use of models in Secondary schools in Nsit Atai Local Government Area.
1.5 Delimitation of Study
The study was restricted to selected secondary schools in Nsit Atai Local Government Area and it involved only Public Senior Secondary Schools two (SS2) students offering Biology as a subject in all the six public secondary schools in the study area.
1.6 Limitation of the Study
The researcher encountered some limitation to the scope of the study
Availability of Research Materials: The research material available to the researcher was insufficient, thereby limiting the study.
Time: the time frame allocated for the study could not enhance wider courage as the researcher has to combine other academic activities and examinations with the study.
1.7 Operational Definition of Terms
Model: This is the physical structure use in teaching to represent realia materials. Models is a man made materials.
Utilization: It is the process of putting things to use.
Biology: Is the study of living and non-living component of the environment.
Gender: This is either sexes (Male and Female), especially when considered with reference to social and cultural differences rather than biological one.
