1.1 Introduction
Instructional materials are defined as teaching and learning resources that support teachers in delivering lessons more effectively and help learners to understand abstract concepts through visual, audio, and practical experiences. According to Ogunyemi (2019), instructional materials include charts, models, real objects, textbooks, and ICT tools that make teaching more meaningful and learner-centered. Business Education is an academic programme designed to equip learners with knowledge and practical skills in areas such as accounting, office practice, marketing, and entrepreneurship for personal and national development (Aina & Adewale, 2020).
In the context of junior secondary schools, Business Education plays a critical role in preparing students with foundational business skills needed for future academic and career advancement. Teaching and learning, as described by Okeke (2018), is a systematic process through which knowledge, skills, and values are transmitted from teachers to learners through interaction, guidance, and instructional support. Therefore, the integration of instructional materials in Business Education is essential for improving comprehension, motivation, and academic performance among students in junior secondary schools in Nigeria.
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, limitation of the study and definition of terms.
1.2 Background of Study
The use of instructional materials in education has evolved from traditional teaching aids such as chalkboards, charts, and real objects to modern digital and multimedia resources that support interactive learning. According to Ogunyemi (2019), instructional materials have long been recognized as essential tools that enhance teaching effectiveness by making learning more concrete and understandable. In the early stages of education development, teaching in Nigerian schools was largely teacher-centered, relying mainly on verbal instruction and rote memorization, which limited students' understanding of practical concepts in subjects like Business Education.
Aina and Adewale (2020) stated that, Business Education is a skill-oriented discipline that requires practical demonstration and application for effective learning outcomes. Students perform better when instructional materials are adequately used during teaching, as it allows them to relate classroom knowledge to real-life business situations. According to Okeke (2018), teaching and learning effectiveness depends largely on the availability and utilization of appropriate instructional resources. Okeke contended that teachers who use instructional materials regularly tend to achieve better classroom outcomes compared to those who rely solely on verbal instruction. He also stated that learner engagement increases when students are exposed to visual and practical learning aids.
Federal Government of Nigeria (FGN, 2014) articulated that, the National Policy on Education emphasizes the use of instructional materials as a key requirement for effective curriculum implementation at all levels of education. The policy affirmed that adequate provision and utilization of teaching resources improve the quality of education delivery and promote skill acquisition among learners. However, despite this policy direction, many junior secondary schools in Nigeria still face challenges such as inadequate instructional materials, poor funding, and lack of trained teachers.
Eze (2021) reported that poor academic performance in Business Education is often linked to insufficient instructional materials and ineffective teaching strategies. On the other hand, schools that invest in teaching aids and practical demonstrations tend to record higher student achievement and better learning outcomes. According to Nwosu (2022), the integration of instructional materials in classroom instruction promotes critical thinking and skill development among students. Nwosu stated that learners are more likely to retain knowledge when they are actively involved in learning through the use of teaching aids. The author further affirmed that instructional materials serve as a motivational tool that enhances students' interest in Business Education.
This study is set against the backdrop of the persistent decline in students' performance in Business Education and the growing concern over inadequate use of instructional materials in junior secondary schools in Nigeria.
1.3 Statement of Problems
Investigation revealed that the use of instructional materials for effective teaching and learning of Business Education in junior secondary schools is inadequate and poorly implemented, leading to low student engagement and weak academic performance in the subject. Teachers often rely heavily on verbal instruction due to shortage of teaching aids, inadequate training, and lack of institutional support, which reduces students' ability to understand practical business concepts. On the other hand, where instructional materials are available, they are often not properly utilized due to large class sizes and insufficient time for practical demonstrations.
Furthermore, many schools is experiencing challenges related to poor funding, making it difficult to procure modern instructional materials such as ICT tools and business simulation resources. Students is also being denied practical exposure that is essential for skill development in Business Education, thereby affecting their preparedness for real-life business environments. It is against this backdrop that this study seeks to examine the use of instructional materials for effective teaching and learning of Business Education in junior secondary schools.
