Project – Influence of Computer-Assisted Instruction on Students’ Performance in Geometry

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Mathematics is a fundamental subject in the educational system, providing students with essential analytical, problem-solving, and logical reasoning skills (Aina & Ogunsanya, 2018). Geometry, a branch of mathematics concerned with the properties and relationships of points, lines, surfaces, and solids, plays a critical role in developing spatial reasoning, visualization, and higher-order thinking among students (Owolabi, 2019). Despite its importance, students in junior secondary schools often perform poorly in geometry due to its abstract nature and the challenges in visualizing geometric concepts.

The use of Computer-Assisted Instruction (CAI) has emerged as a powerful strategy to enhance learning outcomes in mathematics (Onyeka & Nwafor, 2020). CAI refers to the use of computers to deliver instructional content, provide interactive exercises, and offer immediate feedback, enabling students to learn at their own pace and engage actively with the learning material (Igwe, 2017). In geometry, CAI can help students visualize shapes, manipulate geometric figures, and explore mathematical relationships dynamically, which may improve understanding and retention (Adeyemi & Olaniyan, 2021).

Studies have shown that technology-enhanced instruction, including CAI, can improve students’ academic performance and motivation in mathematics (Ajuwon & Falade, 2018). However, in many Nigerian junior secondary schools, traditional teaching methods—primarily lecture-based with chalkboard illustrations—remain dominant, limiting students’ interaction with abstract geometric concepts (Akpan & Effiom, 2017). This gap highlights the need to investigate the extent to which CAI can influence students’ performance in geometry and provide evidence-based recommendations for effective integration of technology in mathematics education.

1.2 Statement of the Problem

Geometry is a vital component of the mathematics curriculum, yet many students exhibit poor performance at the junior secondary school level. National and regional examinations often reveal low scores in geometry, suggesting that traditional teaching methods may not adequately address students’ learning needs (WAEC, 2022).

One major factor contributing to poor performance is the limited use of Computer-Assisted Instruction in teaching geometry. Many teachers rely heavily on lecture and chalkboard methods without leveraging the interactive and visual benefits of CAI (Igwe, 2017). As a result, students struggle to understand spatial relationships, geometric properties, and problem-solving techniques, leading to low achievement and diminished interest in mathematics (Onyeka & Nwafor, 2020).

Despite increasing global advocacy for technology integration in education, empirical research on the effectiveness of CAI in improving students’ performance in geometry, particularly in the Nigerian junior secondary school context, remains limited. Therefore, this study seeks to examine the influence of CAI on students’ performance in geometry, with a view to providing practical strategies for enhancing mathematics instruction.

1.3 Objectives of the Study

The general objective of this study is to examine the influence of Computer-Assisted Instruction on students’ performance in geometry in junior secondary schools. The specific objectives are to:

1. Determine the extent to which Computer-Assisted Instruction is used in teaching geometry.

2. Assess the relationship between the use of Computer-Assisted Instruction and students’ performance in geometry.

3. Identify challenges faced by teachers in implementing Computer-Assisted Instruction.

4. Suggest strategies to enhance the effective use of Computer-Assisted Instruction in geometry teaching.

1.4 Research Questions

This study seeks to answer the following research questions:

1. To what extent is Computer-Assisted Instruction used in teaching geometry in junior secondary schools?

2. What is the relationship between the use of Computer-Assisted Instruction and students’ performance in geometry?

3. What challenges do teachers face in implementing Computer-Assisted Instruction in geometry lessons?

4. What strategies can be employed to enhance the effective use of Computer-Assisted Instruction in geometry teaching?

1.5 Research Hypothesis

The study will test the following hypothesis at a 0.05 level of significance:

H₀: Computer-Assisted Instruction has no significant influence on students’ performance in geometry in junior secondary schools.
H₁: Computer-Assisted Instruction has a significant influence on students’ performance in geometry in junior secondary schools.

1.6 Significance of the Study

The findings of this study are significant in several ways:

• For teachers: It will provide insights into effective teaching strategies that incorporate technology to improve students’ understanding of geometry.

• For students: The study will enhance engagement, understanding, and performance in geometry through interactive learning approaches.

• For curriculum planners and policymakers: The results will inform policies on the integration of computer-assisted tools in mathematics teaching and teacher training programs.

• For researchers: The study will contribute to the body of knowledge on the effectiveness of technology-based instruction in mathematics education.

1.7 Scope of the Study

The study focuses on the influence of Computer-Assisted Instruction on students’ performance in geometry in selected junior secondary schools. It covers students in the first and second years to capture foundational learning experiences. The research is limited to schools with access to computer facilities to examine the practical implementation of CAI.

1.8 Operational Definition of Terms

• Computer-Assisted Instruction (CAI): The use of computers to deliver lessons, provide interactive exercises, and offer feedback to students (Igwe, 2017).
