CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Biology is one of the foundational science subjects in the Nigerian secondary school curriculum. It provides learners with essential knowledge about living organisms, their environments, and the interactions that sustain life. The importance of Biology extends beyond classroom learning—it serves as a critical gateway to careers in medicine, pharmacy, nursing, agriculture, biotechnology, and environmental science. In today’s world, where global health and environmental issues are pressing concerns, understanding biological principles has become even more essential. Hence, the teaching and learning of Biology should be engaging and effective to meet the academic and career aspirations of students.

Despite the critical role Biology plays, the academic performance of students in this subject has continued to decline in many secondary schools across Nigeria. Specifically, in Ojo Local Government Area of Lagos State, poor performance in Biology has been consistently highlighted in both internal and external examinations. According to Okebukola (2012), many students fail to achieve satisfactory grades due to several factors, among which the teaching method remains prominent. Instructional strategies that rely heavily on rote memorization and teacher-centered lectures do not support deep learning or skill development. This problem has persisted, limiting students’ potential and reducing their competitiveness for science-related opportunities.

In contrast, activity-based instruction (ABI) is gaining global recognition as an innovative method that can improve students’ engagement and achievement, particularly in science subjects. This method emphasizes the learner’s active involvement through experiments, observations, group projects, and real-life problem-solving tasks. ABI is rooted in the constructivist learning theory, as proposed by Bruner (1961) and Piaget (1973), which posits that learners build new knowledge through meaningful interactions with their environment and prior experiences. Instead of being passive recipients of information, students under ABI participate actively, reflect on their experiences, and collaborate with peers, thus fostering a deeper understanding of scientific concepts.

The use of ABI in teaching Biology promotes the development of both cognitive and psychomotor skills, which are crucial for scientific literacy. For instance, when students are allowed to dissect organisms, use microscopes, or model biological systems, they become more engaged and interested in learning. Adesoji and Olatunbosun (2008) assert that such involvement makes abstract biological concepts more concrete and memorable. Furthermore, Akinbobola (2009) and Oloruntegbe (2010) report that students taught with ABI methods tend to perform significantly better than those taught with traditional approaches. They also demonstrate improved retention, problem-solving ability, and interest in science-based careers.

Despite the potential benefits, activity-based instruction is still underutilized in many Nigerian classrooms. Several factors may contribute to this, including limited resources, overcrowded classrooms, lack of teacher training, and rigid curriculum structures. In regions like Ojo, where many public secondary schools face infrastructural and instructional challenges, the adoption of ABI remains inconsistent. Many Biology teachers still depend on conventional lectures, chalk-and-talk methods, and textbook recitations, which do not sufficiently support experiential learning. Consequently, students miss out on the rich, interactive learning experiences that can make Biology more accessible and enjoyable.

It is within this context that the present study seeks to explore the effect of activity-based instruction on students’ academic achievement in Biology in selected secondary schools in Ojo Local Government of Lagos State. By comparing students taught with ABI to those taught using traditional methods, the study aims to determine the effectiveness of this instructional approach and its potential to improve performance and interest in Biology. The findings are expected to provide useful insights for educators, curriculum developers, and policymakers in their quest to improve science education outcomes in Nigeria.

1.2 Statement of the Problem

The persistent underperformance of students in Biology at the secondary school level has become a major concern for educators, parents, and educational stakeholders across Nigeria. In national examinations such as the West African Senior School Certificate Examination (WASSCE) and the National Examination Council (NECO), a significant number of students record poor results in Biology. According to the WAEC Chief Examiners’ Reports (2020), many students exhibit limited understanding of fundamental biological concepts, struggle with scientific reasoning, and demonstrate weak practical and analytical skills. This trend not only hinders students’ academic progress but also restricts access to science-based courses and professional careers.

One of the major contributors to this problem is the method of instruction adopted in the teaching of Biology. In many public schools, including those in Ojo Local Government Area of Lagos State, teachers predominantly use traditional lecture methods. These teacher-centered approaches often involve dictation of notes, rote memorization, and minimal classroom interaction. While these methods may facilitate syllabus coverage, they do little to stimulate students’ interest, creativity, or critical thinking. Consequently, students tend to become disengaged, and the learning experience becomes mechanical rather than meaningful.

In contrast, activity-based instruction (ABI) has been widely recognized as a more effective and student-centered approach to science education. It emphasizes active participation, experimentation, group work, and discovery learning, which align well with the practical and exploratory nature of Biology. However, despite the growing global advocacy for ABI, its actual implementation in Nigerian public secondary schools remains minimal. In Ojo Local Government, many schools lack the facilities, training, and instructional resources necessary to effectively incorporate ABI into classroom practice. As a result, Biology lessons continue to be delivered in abstract and uninspiring ways that do not promote deep understanding or academic success.

Moreover, while several studies have shown the benefits of ABI in enhancing student achievement in other subjects and regions, there is limited empirical data specifically addressing its effectiveness within the context of public schools in Ojo. Without such localized evidence, it becomes difficult for teachers, school administrators, and policymakers to make informed decisions about instructional reforms or resource allocation. This gap in knowledge and practice continues to widen the achievement gap in Biology, leaving many students underprepared for higher education and scientific careers.

Therefore, this study seeks to investigate whether the use of activity-based instructional methods can lead to a significant improvement in students’ academic achievement in Biology in selected secondary schools in Ojo Local Government Area, Lagos State. By comparing the performance of students taught using ABI to those taught through conventional methods, the study aims to provide evidence-based insights that can inform teaching practices and educational policy decisions.

1.3 Objectives of the Study

H₀: There is no significant difference in the academic achievement of students taught Biology using activity-based instruction and those taught using conventional methods.

H1: There is a significant difference in the academic achievement of students taught Biology using activity-based instruction and those taught using conventional methods.

1.6 Significance of the Study

This study is significant as it aims to provide empirical evidence on the effectiveness of activity-based instruction in enhancing students’ academic performance in Biology. By focusing on secondary schools in Ojo Local Government Area of Lagos State, the study addresses a specific educational context where the traditional lecture method still dominates classroom instruction. The findings will help to assess whether adopting a more interactive, student-centered instructional approach can yield measurable improvements in students’ academic outcomes in Biology.

Teachers, as key implementers of curriculum content, will greatly benefit from the findings of this study. The research will highlight the instructional value of activity-based methods and how they can be practically integrated into Biology lessons to promote active engagement and critical thinking. With increased awareness and understanding of ABI, teachers may be motivated to shift away from purely didactic methods and adopt more innovative practices that cater to different learning styles and abilities, thereby improving teaching effectiveness and student performance.

Students are at the center of this study, and its outcomes are intended to positively impact their learning experience. Activity-based instruction fosters hands-on learning, exploration, and collaboration, which have been shown to improve knowledge retention and conceptual understanding. By promoting active participation, the approach may also increase students’ interest and motivation in Biology. Ultimately, enhanced learning experiences can lead to better academic performance and a stronger foundation for science-related careers, particularly in the 21st-century knowledge economy.

School administrators and policymakers stand to benefit from the policy implications of the study. With empirical data on the effectiveness of ABI, school leaders and education authorities can make informed decisions about resource allocation, professional development, and curriculum enhancement. The study could support initiatives aimed at improving teacher training programs, updating the science curriculum to include more experiential learning, and equipping schools with necessary laboratory and instructional materials. Such reforms would help to bridge the gap between policy and practice in science education.

Additionally, curriculum planners and educational consultants will find the study useful in designing content that supports learner-centered strategies. By aligning curriculum objectives with instructional methodologies that promote deep learning, planners can help create a more engaging and relevant science education framework. This, in turn, may improve students’ learning outcomes and prepare them better for national and international assessments, as well as for lifelong learning.

Lastly, researchers and academic scholars will benefit from the study as it contributes to the existing literature on effective teaching methodologies in science education. It provides a contextual analysis of how ABI affects learning outcomes in a Nigerian setting, thereby filling a gap in localized research. The findings may stimulate further studies on similar instructional approaches across different subjects and regions. This will help in building a robust evidence base to support continuous improvement in the quality of teaching and learning in Nigerian schools.

1.7 Scope of the Study

This study is limited to selected public secondary schools within Ojo Local Government Area of Lagos State. It focuses on senior secondary school students (SS2) offering Biology. The research will examine the impact of activity-based instruction on their academic performance, interest, and participation. The study will also investigate the perceptions of Biology teachers regarding ABI and explore gender-related differences in performance.

1.8 Operational Definition of Terms

Activity-Based Instruction : Activity-Based Instruction refers to a student-centered teaching approach that emphasizes active participation in the learning process through hands-on activities, practical experiments, fieldwork, role-playing, and group discussions. This instructional method enables learners to construct knowledge by interacting with real-life materials and engaging in inquiry-based tasks. Unlike conventional teaching, which focuses on passive listening and note-taking, activity-based instruction encourages exploration, collaboration, critical thinking, and problem-solving, which are crucial for effective science learning, especially in subjects like Biology.

Academic Achievement: Academic Achievement in the context of this study denotes the measurable performance of students in Biology, as reflected in their test scores, examination results, or assessments. It is used as an indicator of the students’ understanding and mastery of biological concepts. Academic achievement is a key outcome variable in this study, as it helps to determine the effectiveness of different instructional methods—specifically, the impact of activity-based instruction versus conventional teaching on student learning outcomes in Biology.

Conventional Method: Conventional Method, also known as the traditional method of teaching, is a teacher-centered instructional strategy that relies primarily on lectures, verbal explanations, textbook reading, and note dictation. In this method, the teacher serves as the sole source of knowledge, while students play a passive role in the learning process. This approach is often criticized for limiting students’ critical thinking, creativity, and engagement, especially in science subjects that require practical demonstration and experiential learning.

Biology: Biology is defined as a branch of natural science that deals with the study of living organisms and life processes. It encompasses a wide range of topics including cell biology, genetics, ecology, evolution, anatomy, and physiology. As a subject in the secondary school curriculum, Biology provides foundational knowledge that is essential for careers in medicine, agriculture, biotechnology, and environmental science. Given its empirical nature, Biology is best taught using instructional strategies that promote observation, experimentation, and real-world application.

Student Interest: Student Interest refers to the degree of curiosity, enthusiasm, and attention that learners exhibit toward the study of Biology. It plays a critical role in influencing students’ engagement, participation, and academic achievement. When students are interested in a subject, they are more likely to invest effort, ask questions, and retain information. Activity-based instruction is believed to have a positive effect on student interest by making learning more interactive, relatable, and enjoyable.
