PROBLEM SOLVING IN BIOLOGY TEACHING ON STUDENTS ACTIVITIES AND THEIR PERFORMANCE IN NIGERIA ( A CASE STUDY OF EKITI STATE)

ABSTRACT

The integration of problem-solving activities in Biology teaching plays a crucial role in enhancing students' academic performance, retention of biological concepts, and attitudes toward the subject. This study examined the extent to which problem-solving activities are incorporated into Biology teaching in secondary schools in Ekiti State, Nigeria, and their impact on students' learning outcomes. A cross-sectional survey research design was adopted, with data collected from 300 students Biology teachers across 10 secondary schools using a structured questionnaire. The findings revealed a significant relationship between the integration of problem-solving activities and students' academic performance, retention, and attitudes toward Biology. Additionally, teachers faced significant challenges in implementing problem-solving strategies, including a lack of instructional materials, time constraints, and inadequate training. These findings align with previous studies emphasizing the importance of interactive teaching methods in science education. The study recommends increased teacher training, provision of adequate resources, and curriculum adjustments to facilitate the effective integration of problem-solving activities. Addressing these challenges will enhance students' understanding of Biology and improve their overall academic performance.

CHAPTER ONE

INTRODUCTION

1. Background of the Study

Problem-solving is a fundamental skill in science education, particularly in Biology, where students must develop analytical abilities to comprehend biological concepts and apply them to real-life scenarios. The ability to solve problems effectively in Biology requires students to engage in critical thinking, experimentation, and inquiry-based learning (Owolabi & Oginni, 2020). However, in Nigeria, and particularly in Ekiti State, concerns have been raised over students’ declining performance in Biology. This has been largely attributed to the predominant use of traditional teaching methods, which emphasize rote memorization rather than practical applications of scientific knowledge (Aina & Ayodele, 2019). Consequently, students struggle to internalize key biological concepts, leading to poor problem-solving skills and an overall decline in academic achievement in the subject.

The Nigerian educational system underscores the importance of science subjects, including Biology, in preparing students for careers in health, environmental science, and biotechnology. Despite this emphasis, secondary school students in Ekiti State often face difficulties in applying problem-solving techniques to Biology-related tasks, which significantly impacts their academic performance (Adeyemo, 2021). Research has shown that students who engage in active learning activities—such as laboratory experiments, case studies, and collaborative discussions—tend to perform better in science subjects because these activities enhance critical thinking and knowledge retention (Ibrahim & Jimoh, 2022). Unfortunately, many Biology classrooms in Ekiti State lack the necessary resources, such as well-equipped laboratories and trained teachers proficient in inquiry-based teaching. This lack of facilities and instructional support limits students' opportunities to engage in problem-solving activities, thereby affecting their overall comprehension of Biology (Okeke & Abimbola, 2020).

Moreover, the effectiveness of problem-solving approaches in Biology teaching is closely tied to the instructional strategies employed by teachers. Studies have demonstrated that a student-centered approach, which encourages active participation through brainstorming sessions, experiments, and real-life problem analysis, improves students’ ability to understand and apply biological concepts (Obi & Afolabi, 2018). However, in Ekiti State, Biology instruction is often dominated by teacher-centered methodologies, where students are passive recipients of knowledge rather than active participants in the learning process. This teaching style has been identified as a major obstacle to the development of problem-solving skills among students, leading to widespread difficulties in grasping complex biological topics such as genetics, evolution, and ecology (Nwachukwu & Uche, 2019).

Another critical issue is the students' attitudes and motivation towards Biology, which are significantly influenced by the nature of the teaching and learning process. When students are not engaged in interactive and practical activities, they often develop a negative perception of the subject, seeing it as abstract and difficult (Ajayi & Oladipo, 2020). In contrast, students who are actively involved in Biology lessons through inquiry-based learning tend to exhibit higher interest and enthusiasm, which translates to better performance in assessments and examinations (Eze & Onuoha, 2021). However, due to the heavy reliance on traditional teaching methods in Ekiti State, many students lack the necessary exposure to hands-on problem-solving activities, thereby reinforcing the cycle of poor performance in Biology.

Additionally, socio-economic factors play a crucial role in shaping students’ engagement with problem-solving activities in Biology. Many schools in Ekiti State, particularly those in rural areas, suffer from inadequate funding, which affects the availability of instructional materials, laboratory equipment, and professional development programs for teachers (Ogunleye & Adeleke, 2019). As a result, teachers often resort to theoretical instruction rather than practical-based learning, which is essential for developing students’ problem-solving competencies. The disparity in educational resources between urban and rural schools further exacerbates the challenges, as students in underprivileged areas are less likely to have access to quality Biology education that incorporates problem-solving methodologies (Bamidele & Okon, 2020).

Despite these challenges, research has suggested that implementing problem-solving strategies in Biology teaching can significantly improve students' academic outcomes. Educational interventions, such as project-based learning, peer-led discussions, and the use of digital tools for virtual simulations, have been shown to enhance students’ engagement and problem-solving abilities (Adeyemi & Yusuf, 2022). Schools that have adopted these approaches have reported improved performance in Biology examinations, as students are better able to analyze, interpret, and apply biological concepts to real-world situations. However, for such approaches to be effective in Ekiti State, there is a need for policy reforms that emphasize training teachers in modern pedagogical methods and equipping schools with adequate learning resources (Olatunji & Fagbohun, 2021).

Given the crucial role of problem-solving in Biology education, it is imperative to investigate the extent to which students’ activities influence their academic performance in the subject. This study seeks to examine the relationship between problem-solving approaches and student performance in Biology within Ekiti State secondary schools. By analyzing the effectiveness of various teaching methodologies, the study aims to provide insights into how educators can enhance student engagement and achievement in Biology. The findings will contribute to ongoing discussions on educational reform, with the goal of improving Biology teaching and learning outcomes through the adoption of problem-solving strategies.

1. Statement of the Problem

Biology is a core science subject in the Nigerian secondary school curriculum and plays a crucial role in shaping students' understanding of life sciences and their applications. However, despite its importance, students’ performance in Biology has been consistently poor, particularly in Ekiti State (Ajayi & Oladipo, 2020). Studies have linked this poor performance to a lack of problem-solving activities in Biology teaching, where students are often taught using traditional lecture-based methods that emphasize memorization rather than practical application (Adeyemo, 2021). This approach hinders students’ ability to analyze biological concepts critically, solve real-world problems, and develop scientific inquiry skills, ultimately affecting their academic achievement in the subject.

A key issue contributing to this problem is the limited use of student-centered learning activities, such as laboratory experiments, collaborative projects, and inquiry-based instruction, which have been shown to enhance problem-solving skills and knowledge retention (Ibrahim & Jimoh, 2022). Many teachers in Ekiti State still rely on teacher-centered approaches, where students passively receive information without actively engaging in the learning process (Nwachukwu & Uche, 2019). This teaching style discourages creativity and independent thinking, making it difficult for students to apply biological principles to solve complex problems. Research has shown that when students are actively involved in hands-on learning experiences, their comprehension of Biology improves significantly, leading to better performance in examinations and practical assessments (Eze & Onuoha, 2021).

Furthermore, the inadequate provision of instructional resources, such as well-equipped laboratories, teaching aids, and digital learning tools, exacerbates the challenges faced by students in developing problem-solving skills in Biology (Bamidele & Okon, 2020). Many secondary schools in Ekiti State, particularly those in rural areas, lack the necessary infrastructure to support practical-based learning, forcing teachers to resort to theoretical instruction (Ogunleye & Adeleke, 2019). The absence of hands-on learning opportunities means that students are not exposed to critical thinking exercises and real-life applications of biological concepts, which are essential for academic success in science-related disciplines.

Another major concern is the attitude of students towards Biology, which is significantly influenced by the teaching methodologies employed in the classroom. Research has indicated that when students find Biology lessons engaging, interactive, and problem-solving oriented, they develop a positive attitude towards the subject and perform better academically (Obi & Afolabi, 2018). However, in cases where learning is monotonous and lacks interactive elements, students tend to lose interest, leading to low motivation and poor academic performance (Ajayi & Oladipo, 2020). This trend is particularly evident in Ekiti State, where a large percentage of students struggle with Biology due to a lack of stimulating and problem-based learning experiences.

Given these challenges, it is essential to investigate the impact of problem-solving activities on students' academic performance in Biology. Understanding the extent to which problem-solving strategies enhance students' comprehension and application of biological concepts will provide valuable insights into improving Biology teaching methods in Ekiti State (Adeyemi & Yusuf, 2022). This study seeks to explore the relationship between students’ engagement in problem-solving activities and their performance in Biology, with the aim of identifying effective strategies that can enhance learning outcomes. By addressing this gap, the study will contribute to ongoing efforts to improve science education in Nigeria, ensuring that students develop the critical thinking and problem-solving skills necessary for academic and professional success.
