1.0 Introduction
1.1 Background of Study
Over the years, numerous teaching methods have been proposed and implemented to enhance students' learning experiences and outcomes in mathematics. Traditional methods, such as direct instruction, emphasize a teacher-centered approach where the teacher imparts knowledge through lectures and demonstrations. While this method has been effective in some contexts, it has also been criticized for not engaging students actively in the learning process (Good & Brophy, 2008).
The effectiveness of various teaching methods on students' academic outcomes has been a topic of considerable interest and debate within educational research. This meta-analysis targets to synthesize existing studies to evaluate the impact of different instructional strategies on students' achievement, interest, and retention in mathematics. The teaching of mathematics has long been recognized as a critical component of education, essential for the development of logical reasoning, and the ability to understand and manipulate quantitative information. Despite its importance, mathematics education faces persistent challenges, including varying levels of student achievement, waning interest, and difficulties in retention of knowledge.
In the field of mathematics education, early meta-analyses primarily focused on comparing traditional and innovative teaching methods. For instance, researchers began to systematically examine the effects of direct instruction versus discovery learning in the late 20th century. A seminal meta-analysis by Hattie (2009) consolidated findings from over 800 meta-analyses on various educational influences, including teaching methods, revealing that certain interactive approaches had a more substantial impact on student achievement than traditional lecture-based methods.
The advent of technology in education has further expanded the range of teaching methods available. Tools such as computer-assisted instruction, online tutorials, and interactive simulations offer new ways to present mathematical concepts and engage students. Research has suggested that technology-enhanced learning can be particularly effective in catering to diverse learning styles and needs (Roschelle et al., 2000). Despite the proliferation of research on different teaching methods, there remains a need for a comprehensive analysis that synthesizes these findings to provide clear guidance on which methods are most effective. This meta-analysis addresses this gap by systematically reviewing and analyzing studies on the impact of various teaching methods on students' achievement, interest, and retention in mathematics.
More recently, meta-analyses have started to explore the differential effects of teaching methods across various demographic groups, recognizing that factors such as socioeconomic status, gender, and cultural background can influence the efficacy of instructional strategies. This nuanced approach aims to identify which teaching methods are most effective for diverse student populations, contributing to more equitable educational practices. The continuous development of meta-analytic techniques, along with the increasing availability of research data, has enabled more sophisticated and comprehensive analyses. Today, meta-analyses in mathematics education not only compare the overall effectiveness of teaching methods but also examine specific components and contextual factors that contribute to their success.
Therefore, in Nigeria Study where the research was carried out, the activities that was conducted is to know the effect of teaching methods on students' achievement, interest and retention in mathematics.
1.2 Statement of the Problem
Investigation revealed that the numerous studies have investigated the impact of different teaching methods on students' mathematical outcomes, but the findings are often inconsistent and contradictory. For instance, while some research suggests that inquiry-based learning significantly improves student achievement, other studies indicate minimal or no impact (Alfieri et al., 2011; Hattie, 2009). This inconsistency complicates efforts to draw definitive conclusions about the efficacy of various instructional approaches.
Additionally, many studies focus narrowly on student achievement, often measured by test scores, without considering other important outcomes such as interest in mathematics and long-term retention of knowledge. This narrow focus overlooks the broader goals of education, which include fostering a sustained interest in the subject and ensuring that students retain what they have learned over time (National Research Council, 2000). Also, educators and policymakers require clear, evidence-based recommendations to implement the most effective teaching strategies in mathematics education. The current fragmented state of research makes it challenging to provide such guidance. A comprehensive meta-analysis can consolidate findings across studies, offering more reliable and actionable insights (Slavin, 2008).
Furthermore, teaching methods may vary in effectiveness depending on contextual factors such as classroom environment, student demographics, and available resources. However, there has been insufficient synthesis of how these factors influence the success of different instructional strategies (Darling-Hammond, 2000). Hence, it is against this backdrop that this study aims to investigate the effect of teaching methods on students’ achievement, interest and retention in mathematics.
1.3 Aim and Objectives of Study

- To identify which teaching methods are most effective in improving students' mathematical skills and knowledge;
- To determine how the quality of the research affects the reliability and validity of the findings on mathematics teaching methods; and
- To identify any differential effects of instructional strategies across diverse educational settings and student populations.
1.4 Research Questions
The study came up with research questions so as to be able to ascertain the above stated objectives. The specific research questions for the study are stated below as follows:
