The Effect Of Instructional Materials On The Learning And Teaching Of Economics In Senior Secondary Schools In Isolo LGA
The study aimed at examining the effects of economics instructional materials on the learning and teaching of economics as well the effects of these instructional materials on the academic performance of some secondary school students in some selected secondary schools in Isolo Local Government Area of Lagos state. A well designed and simple questionnaire was distributed to economics teachers in these selected schools to accurately evaluate the effect of instructional materials on the application of learning economics in secondary schools in Nigeria.
Concerning methodology used for the study, the researcher adopted the survey research design with a sample size of twenty (20) teachers and eighty (80) students selected using a stratified sampling technique. Both primary and secondary data was used for the study. Questionnaires formed the basis for primary data for the study, while text books, internet, journals and magazines were the secondary sources of data for the study.
The finding after testing hypothesis three indicates that there will be a significant positive difference in the performance of secondary school students in Economics language when they are taught the subject with instructional materials. The use of instructional materials in the teaching and learning of Economics obviously improves the performance of students.
Schools should provide enough instructional materials to enable teachers clarify their lesson. Adequate infrastructure facilities and conclusive atmosphere are Sine Qua Non for effective learning and retention of what is learnt. Schools should send their Economics teachers to seminars and workshops in order to up date their knowledge.
1.1 Background Of The Study
The influence of instructional materials in promoting students’ academic performance and teaching and learning in educational development is indisputable. The teaching of Economics in Nigerian secondary schools needs to be properly handled. The materials used by teachers to teach and drive home their subject points at the primary and secondary school levels of our education system is incontrovertibly a paramount important issue in practical classroom interaction and successful transfer of knowledge from the teacher to the learners.
Instructional materials are materials which assist teachers to make their lessons explicit to learners. They are also used to transmit information, ideas and notes to learners (Ijaduola (1997). Instructional materials include both visuals and audiovisuals such as pictures, flashcards, posters, charts, tape recorder, radio, video, television, computers among others. These materials serve as supplement to the normal processes of instruction.
Economics as a subject came into existence in 1776 via the publication of Adam Smith – the protagonist of the classical school of thought; and since then, it has assumed many roles especially in both political and educational circles. The study of Economics is dichotomised into two major parts, namely microeconomics and macroeconomics. While microeconomics studies the behaviour and operations of the individual units (households, firms and government agencies) in the economy, macroeconomics studies the entire economy in aggregates and averages (Umoh, 2007). According to Aromolaran (2006), three major languages are used in teaching and communicating Economic ideas. These languages include theory or verbal, geometric or graphical, and algebraic or mathematical language.
Economics is an important subject that must be credited by students before gaining admission into any tertiary institution especially the university to study relevant courses like Accountancy, Business Administration, Insurance, etc. The importance and technicality of this subject makes it necessary that relevant instructional materials should be used to teach it to the learners. This fact is supported by Macaulay (1989) who asserts that visual aids make lesson come alive and help students to learn better.
It is against this background that this study attempts to examine the extent to which the utilization of instructional materials could advance senior secondary school students performance in Economics.
Poor academic achievement in Economics could be attributed to many factors among which teacher’s strategy itself was considered as an important factor. This implies that the mastery of Economics concepts might not be fully achieved without the use of instructional materials. The teaching of Economics without instructional materials may certainly result in poor academic achievement. Franzer , Okebukola and Jegede (1992) stressed that a professionally qualified science teacher no matter how well trained, would unable to put his ideas into practice if the school setting lacks the equipment and materials necessary for him or her to translate his competence into reality.
Bassey (2002) opined that Science is resource intensive, and in a period of economic recession, it may be very difficult to find some of the electronic gadgets and equipment for the teaching of Economics in schools adequately. A situation that is further compounded by the galloping inflation in the country and many at times, some of the imported sophisticated materials and equipment are found expensive and irrelevant; hence the need to produce materials locally.
Researchers such as Obioha (2006) and Ogunleye (2002) reported that there were inadequate resources for teaching Science subjects in secondary schools in Nigeria. They further stated that the available ones are not usually in good conditions. There is the need therefore, for improvisation. Adebimpe (1997) and Daramola, (2008) however noted that improvisation demands adventure, creativity, curiosity and perseverance on the part of the teacher, such skills are only realizable through well-planned training programme on improvisation.
1.2 Statement Of The Problem
The act of teaching is fundamentally concerned with passing ideas, skills and attitude from the teacher to the learner. In Nigeria, for example experience has shown that spoken words alone in the communication of ideas are grossly ineffective and inefficient in producing desired learning outcomes. Every year, when the results of public examination are released, there has always been mass failure in Economics.
The reason for this could be ascribed to the fact that there are topics in Economics that pose serious problem of comprehension to students. These topics cannot be taught effectively without the use of relevant instructional materials to make the learning practical. On the foregoing, scholars like Mutebi and Matora (1994) have emphasized the effect of instructional materials utilisation on teaching and learning. According to them, we learn and remember 10% of what we hear, 40% of what we discuss with others and as high as 80% of what we experience directly or practice. However, the questions here are: does the use of instructional materials really influence students’ academic performance? Is teaching effectiveness enhanced by the use of instructional materials?
Could students’ learning be advanced by the use of instructional materials? Finding answers to these questions and more summarizes the entire problem of this study.
1.3 Objectives Of The Study
The objectives of this study are:
- To examine the influence of instructional material utilisation on the teaching of Economics in Senior Secondary Schools in Lagos State;
- To ascertain the extent to which Senior Secondary School student’s learning of Economics can be influenced by the use of instructional materials
- To determine whether there will be any difference in the academic performance of secondary schools students in Economics due to the use of instructional materials.
1.4 Research Questions
In order to achieve the objectives of this study, the following research questions were raised to guide the investigation:
- Will the use of instructional materials influence the teaching and application of Economics in senior secondary schools?
- To what extent can senior secondary school students’ learning of Economics be influenced by the use of instructional materials?
- Will there be any difference in the academic performance of senior secondary school students in Economics due to the use of instructional materials?
1.5 Research Hypotheses
The following null hypotheses were stated for the study.
- The use of instructional materials will not have significant influence on the teaching of Economics in senior secondary schools.
- The use of instructional material will not have significant influence on secondary school students’ learning of Economics.
- There will be no significant difference in the performance of students in Economics due to the use of instructional materials.
1.6 Significance Of The Study
The use of instructional materials gives the learner opportunity to touch, smell or taste objects in the teaching and learning process. Consequently, knowledge passed unto the students at different levels of educational instructions should be well planned and properly allied with relevant instructional materials for clarity and comprehensibility. Hence the significance of this study to the students, teachers, curriculum planners, educational system and the society at large.
To the students, the effective use of instructional materials would enable them to effectively learn and retain what they have learnt and thereby advancing their performance in the subject in question. This is because according to Nwadinigwe (2000), learning is a process through which knowledge, skills, habits, facts, ideas and principles are acquired, retained and utilized; and the only means of achieving this is through the use of instructional materials.
The study would help enhance teachers’ teaching effectiveness and productivity. This is in line with assertion of Ekwueme and Igwe (2001) who noted that it is only the teachers who will guarantee effective and adequate usage of instructional materials and thereby facilitate success. Consequently a teacher who makes use of appropriate instructional materials to supplement his teaching will help enhance students’ innovative and creative thinking as well as help them become plausibly spontaneous and enthusiastic. Oremeji (2002) supportively asserts that any teacher who takes advantage of these resources and learns to use them correctly will find that they make almost an incalculable contribution to instruction. He further says that instructional materials are of high value in importing information, clarifying difficult and abstract concepts, stimulating thought, sharpening observation, creating interest and satisfying individual difference.
The study is also significant to the educational system and society at large. This is because when teachers solidify their teaching with instructional materials and the learners learn effectively, the knowledge acquired will reflect in the society positively. Students will be able to understand the functioning of the economy, interpret government’s economic policies and activity and perform economically better in the choice of life and work.
1.7 Scope Of The Study
This study is focused on investigating the effect of instructional material utilisation on advancing senior secondary school students’ performance in Economics in Lagos State. Due to time and financial constraints, the study is limited to Kosofe Local Government Area of Lagos. This is because the researcher resides in this local government area and as such had the opportunity of having a comprehensive knowledge of the area and its environs. Besides, the study involves only the S.S-2 students of the senior secondary schools in Kosofe Local Government Area of Lagos State.
1.8 Limitations Of Study
The only limitation faced by the researcher in the course of carrying out this study was the delay in getting data from the various respondents. Most respondents were reluctant in filling questionnaires administered to them due to their busy schedules and nature of their work. The researcher found it difficult to collect responses from the various respondents, and this almost hampered the success of this study.
1.8 Definition Of Terms
The relevant terms below were operationally defined relative to their usage in this study.
This is the change (outcome) that is brought about in a person (s) or something by another person (s) or thing; that is the way in which an event, action or person changes someone or something.
This is regarded as the display of knowledge attained or skills, shown in the school subjects such achievements are indicated by test scores or by marks assigned by teachers. It is the school evaluation of students’ classroom work as quantified on the basis of marks or grades.

Summary, Conclusion, And Recommendations
This chapter discusses the finding of this study in relation to the hypotheses formulated and tested. The conclusions are drawn based on the results.
The discussions of the findings are based on the variables which formed the basic of the hypotheses tested in chapter four.
The purpose of the study includes:
- To examine the influence of the use of instructional materials in the teaching of Economics in secondary schools;
- To ascertain the extend to which secondary school students’ learning of Economics can be influenced by the use of instructional materials; and
- To determine whether there will be any difference in the performance of secondary school students in Economics due to the use of instructional materials.
The finding after testing hypothesis one indicates that the use of instructional materials will significantly influence Economics teaching in secondary schools. This result cconlurs with Ajelabi (2000) where he says that instructional materials lend support and authenticity to whatever the teacher says. This enables the learner to confirm or refute the teacher’s assertion. Sharing the above view is Kay (1981) who says that instructional materials help the teacher to teach more effectively.
The finding after testing hypothesis two indicates that the use of instructional materials will have significant positive influence on secondary school students learning of Economics.
This result agrees with the assertion of Aina (1982) where he says that the use of instructional materials for teaching enriches the classroom work and contributes directly and indirectly to effective teaching and learning. Ajelabi (2000) supports Aina (1982) when he says that instructional materials help in focusing attention and motivating learners. He further says that when appropriate instructional materials are used to introduce, develop or conclude a teaching – learning session, learner’s interest are aroused and developed throughout the lesson.
The finding after testing hypothesis three indicates that there will be a significant positive difference in the performance of secondary school students in Economics when they are taught the subject with instructional materials. The use of instructional materials in the teaching and learning of Economics obviously improves the performance of students. Onyejemezi (1984) supports positive performance when instructional materials are used for teaching and learning more permanent.
Maduekwe (2000) supports Onyejemezi (1984) when he says that the use of instructional materials discourage not learning. Further more Oremeji (2002) asserts that instructional information materials are of high value in imparting information, clarifying difficult and abstract concepts, stimulating thoughts, sharpening observation, creating interest and satisfying individual difference. All in all, the use of instructional cannot be over –emphasized as it forms the integral component of classroom teaching.
As a result of evidence gathered from the analysis of data, interpretation of result and discussion of findings of this study, the following conclusions are reached.
The use of appropriate instructional materials helps teachers to make their lession clarifying.
The use of instructional materials helps the students to understand their lesson very well and also retain what is taught. It also discourages rote learning.
There is difference between lesson taught with instructional materials and those taught without instructional materials. There are positive and improved results when students are taught with instructional materials.
Most school do not provide adequate instructional materials for use in the school, thus making the teachers handicapped.
Most teachers find it very tasking improvising instructional materials.
In conclusion, the researcher strongly believes that the best way to drive home teachers point during teaching and learning encounter is through the use of appropriate instructional materials.
5.3 Implication of the Findings for Curriculum Planning and Education Administration
Economics plays on important role in the social, political, economic, educational, industrial and technological development of Nigeria. The development of the country in all ramifications revolves upon a pivot. It is central to every developmental process and it is a potent instrument for national development. The importance and centrality of Economics is not only recognizable by national policy on education but also the constitution of the federal republic of Nigeria.
This pride of place enjoyed by Economics makes it a must that students should be grounded in Economics right from an early stage of life. The teachers have roles to play by making their lessons explicit, understandable and interesting. This could be achieved through the use of appropriate instructional materials. This connotes therefore, that in curriculum planning and Education Administration, students should be encouraged while a more practical and result oriented Economics teaching and learning process be evolved. The language should be given deserved position and attention in school curriculum and timetable.
In line with the findings of this study, the researcher recommends the following:
- Schools should provide enough instructional materials to enable teachers clarify their lesson. Adequate infrastructure facilities and conclusive atmosphere are Sine Qua Non for effective learning and retention of what is learnt.
- Schools should send their Economics language teachers to seminars and workshops in order to up date their knowledge.
- Teachers should be encouraged by the school by paying incentives. They should be upgraded when necessary. This will enable them to improvise instructional materials for teaching.
- Economics teachers should conduct the teaching and learning of the subject effectively, efficiently and interestingly. Their teachers should be resourceful, knowledgeable and vary his teaching method at all times. The teacher should ensure appropriate use of instructional materials during their lesson.
- Teachers should try to improvise instructional materials so that the students will benefit-maximally.
- Parents should provide adequate and necessary learning materials in Economics. This will encourage their wards to read.
- Students should read extensively worth while publications, journals, newspapers, listen to radio and television news in Economics, in addition to their recommended books. This will widen their knowledge to be able to agree and refute what the teacher teaches them. This extensive reading will make them avid readers and fluent speakers of Economics Maduekwe (1998). This will drastically reduce the mass failure in Economics.
In conclusion, teachers are at the centre of educational instruction. They should strive hard to make their teaching very effective. Akande (1989) asserts “the medical doctor buries his mistake, the engineer dies with his mistake but the whole society perishes with the mistake of the teacher. This shows how valuable a teacher is in the growth of an individual and the society at large. Then the teachers of Economics and all other teacher should make imperative to use instructional materials during teaching so that the learners will be influenced positively.
Limitations of Study
The major factor that constituted a limitation to this study was the insincerity of the respondents in supplying appropriate information required of them in relation to their personal data, socio-economic and educational background. Besides, insufficient fund to take the researcher to vast areas like Lekki and Ikorodu areas limited the wider coverage of the study. Time constraint also posed a limitation to the study.
Finally, incessant power failure circumspect the researcher’s ability to get adequate necessary information from the internet, which in turn cushioned the volume of the literature reviewed during the study.
