Project – The Impact of Peer Group Influence on Students’ Academic Performance and Social Behaviour in Selected Secondary Schools in Dekina LGA

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Education is widely recognised as a major instrument for individual development, social integration and national transformation. Through formal education, individuals acquire knowledge, skills, values, attitudes and competencies required for productive participation in society. Secondary education occupies a particularly important position because it serves as a bridge between basic education and tertiary education, vocational training or entry into the world of work. At this level, students are passing through adolescence, a developmental period characterised by significant physical, psychological, emotional and social changes. These changes make the secondary school years particularly important for understanding the factors that influence students’ academic performance and social behaviour.

Academic performance is one of the major indicators of educational success. It refers to the level of achievement demonstrated by students in school subjects, examinations, tests, assignments and other forms of academic assessment. Good academic performance is usually associated with effective learning, persistence, motivation and the ability to achieve specified educational objectives. Poor academic performance, on the other hand, may be manifested through low test and examination scores, poor classroom participation, failure in subjects, truancy and lack of commitment to schoolwork. Although academic performance is influenced by intellectual ability and individual characteristics, it is also affected by family, school and social factors.

One of the social factors that has attracted considerable attention in adolescent development and education is peer group influence. A peer group refers broadly to a group of individuals who are relatively similar in age or social status and who interact regularly. During adolescence, relationships with peers become increasingly important. Adolescents often spend substantial amounts of time with classmates, friends and other young people, and these relationships can influence their attitudes, aspirations, behaviour and decision-making. Brown and Larson (2009) explain that peer relationships become increasingly significant during adolescence because young people develop greater autonomy from parents while simultaneously seeking acceptance and belonging among their peers.

Peer influence can be either positive or negative. Positive peer influence may encourage students to attend school regularly, study diligently, participate in group discussions, assist classmates, obey school rules and develop constructive social relationships. A student surrounded by academically motivated peers may be encouraged to develop similar academic aspirations and study habits. Peer groups can therefore constitute an important informal learning environment in which students exchange knowledge, explain difficult concepts, share learning materials and motivate one another.

Peer influence can also take negative forms. Students may be encouraged by peers to engage in truancy, examination malpractice, bullying, disobedience, substance use, fighting, excessive use of social media, sexual risk-taking or other forms of antisocial behaviour. Where a peer group places greater value on entertainment, risky behaviour or opposition to school authority than on academic achievement, individual members may experience pressure to conform to those expectations. This can reduce the time and attention devoted to schoolwork and potentially affect academic outcomes.

The significance of peer relationships can be explained through social learning perspectives. Bandura (1977) argues that individuals learn many behaviours through observing and interacting with others. People may imitate behaviours exhibited by individuals whom they regard as models, particularly when those behaviours appear to receive approval or reward. In a school context, students may observe the behaviour of their friends and subsequently adopt similar academic, social or behavioural patterns. Consequently, peer groups can become important sources of behavioural modelling.

Peer influence is not necessarily based on direct pressure. Students may voluntarily select friends with similar interests and characteristics, while the resulting relationships can subsequently reinforce particular behaviours. This means that peer selection and peer influence may operate together. Rambaran et al. (2017), in a longitudinal study of adolescents, found evidence of both peer selection and peer influence in academic functioning and truancy. Their findings illustrate that friendships and academic behaviour can influence each other over time rather than operating as completely separate processes.

The relationship between peer relationships and academic engagement has also been demonstrated in empirical research. Mikami et al. (2017) studied 1,084 adolescents across 65 middle and high school classrooms and found that students’ perceived relatedness with classroom peers predicted subsequent behavioural engagement, while engagement was associated with higher end-of-year objective achievement after controlling for prior achievement. This finding suggests that supportive relationships with classmates can contribute to students’ willingness to participate actively in learning.

Peer relationships may therefore influence academic performance through several mechanisms. First, peers can influence academic motivation. Students who associate with peers who value education may develop stronger educational aspirations. Second, peers can influence study habits, as students may organise group study sessions, exchange notes and assist one another with assignments. Third, peers may influence school attendance, since students may encourage one another either to attend or avoid school. Fourth, peer relationships may affect educational expectations, because adolescents often compare their academic abilities and future aspirations with those of their friends.

Recent empirical research has provided further support for the relationship between peer relationships and academic achievement. A 2024 study published in BMC Psychology examined 717 junior high school students and found that peer relationships were directly and significantly associated with academic achievement. The study further reported that learning motivation and learning engagement helped explain the relationship between peer relationships and achievement. This indicates that peer relationships may influence academic outcomes not only directly but also through students’ motivation and engagement in learning.

Evidence from Nigeria also indicates that peer groups are relevant to students’ academic outcomes. Akinbode and Olasunkanmi (2021), in a study of public secondary school students in Ogun State, examined socioeconomic background, peer group and academic achievement among 617 respondents. The researchers reported a positive and significant relationship between peer group and academic achievement. This finding is particularly relevant to the Nigerian educational context because it demonstrates that peer relationships can be associated with differences in students’ academic outcomes within public secondary schools.

Similarly, Oladeji (2021) investigated family size, peer influence and school environment as predictors of academic performance among secondary school students in Ibadan North Local Government Area of Oyo State. The study used 100 respondents and reported a significant relationship between peer influence and students’ academic performance. The finding suggests that peer influence is an educational factor worthy of consideration alongside family and school characteristics.

Ukpabi and Akinyemi (2021) also examined peer group influence and academic performance among secondary school students in Akinyele Local Government Area of Oyo State. Their study reported that peer groups could positively affect students’ academic performance through financial, emotional and social support, while also noting that negative peer influence may require preventive counselling interventions. This demonstrates that peer groups should not automatically be regarded as harmful; rather, their effect depends substantially on the nature and values of the group.

More recent Nigerian evidence continues to demonstrate the importance of peer pressure. Agbajeola (2024) examined internet addiction and peer pressure as determinants of senior secondary school students’ academic performance in Ijebu-Ode Local Government Area of Ogun State. Using 560 students from eleven schools, the study reported that peer pressure significantly determined academic performance. Similarly, research published in 2025 on secondary school students in Ijebu East Local Government Area of Ogun State examined peer pressure and school environment and further highlighted the importance of peer-related factors in understanding academic performance.

The influence of peer groups extends beyond academic performance to students’ social behaviour. Social behaviour refers to the manner in which individuals interact with others and respond to social situations. In secondary schools, it may be reflected in cooperation, respect for teachers and classmates, friendship formation, communication, leadership, discipline, aggression, bullying, conformity and compliance with school rules. Because adolescents spend considerable time with peers, their social behaviour may be shaped by the norms and expectations of their peer groups.

A peer group can provide an environment in which positive social behaviours are developed. Students may learn cooperation by working together on assignments and extracurricular activities. They may develop leadership skills by participating in group activities and learn empathy by supporting friends who experience difficulties. Positive peer relationships can also provide emotional support, a sense of belonging and social acceptance. Such relationships can contribute to students’ adjustment to school and enhance their confidence in participating in classroom and social activities.

However, peer groups may also reinforce undesirable social behaviours. Students may adopt behaviours that are rewarded or accepted within their friendship groups, even when those behaviours conflict with school rules or broader social expectations. For example, if aggression, bullying, disrespect for teachers or truancy is regarded as acceptable within a peer group, individual students may be more likely to imitate or tolerate such behaviour. The desire to maintain group membership can create pressure to conform.

The relationship between peer behaviour and academic outcomes can also be reciprocal. Students who perform poorly or frequently engage in misconduct may seek out peers with similar characteristics, while their subsequent relationships may reinforce those behaviours. Rambaran et al. (2017) found evidence of reciprocal dynamics between friendship networks and academic functioning, including achievement and truancy. Thus, it is inappropriate to assume that peer influence always moves in one direction.

The concept of peer influence is especially important during adolescence because young people increasingly develop identities and social networks outside the immediate family. Brown and Larson (2009) note that peer relationships provide adolescents with opportunities for social comparison, identity development and the acquisition of interpersonal skills. As students become more independent, the opinions and behaviours of friends may become increasingly influential in shaping their choices.

The school itself provides an important setting for peer interaction. Students are grouped together in classrooms, clubs, sporting activities and other school programmes. These repeated interactions provide opportunities for friendships and informal social networks to develop. In such circumstances, students can influence one another’s academic expectations, behaviour and attitudes toward school. Therefore, the school environment cannot be understood solely in terms of teachers, curriculum and physical facilities; peer relationships constitute an important component of students’ everyday educational experiences.

In Nigeria, concerns about students’ academic performance and social behaviour remain important. Schools are expected not only to produce students who perform well academically but also young people who demonstrate discipline, responsibility, cooperation and respect for others. When negative peer influence contributes to truancy, indiscipline, bullying or other antisocial behaviour, it can undermine the educational objectives of the school. Indeed, research specifically conducted in Dekina Local Government Area has identified indiscipline as a concern in relation to students’ academic performance. Enefu et al. examined indiscipline and academic performance among secondary school students in Dekina LGA and reported a study population comprising 42 secondary schools, 2,503 students and 300 teachers.

Dekina Local Government Area of Kogi State provides a meaningful context for examining peer group influence because secondary school students interact within a range of social, family and school environments. Students in the area may belong to different peer networks with different attitudes toward education, social relationships and school rules. Some groups may encourage academic commitment, while others may encourage behaviours that compete with educational objectives.

The local context is important because findings from another geographical area may not necessarily apply directly to Dekina. Peer relationships are shaped by culture, community norms, family expectations, school organisation and the characteristics of the students involved. For this reason, empirical evidence specific to the study area is necessary.

Although existing Nigerian studies have established relationships between peer influence and academic outcomes in locations such as Ogun, Oyo and other states, relatively limited empirical attention has been directed specifically toward the combined influence of peer groups on both academic performance and social behaviour among secondary school students in selected schools in Dekina LGA. Recent studies continue to examine peer dynamics in other Nigerian locations, including Awka Urban in Anambra State, where researchers investigated peer academic support, peer pressure and academic performance among students in public secondary schools.

The distinction between positive and negative peer influence is particularly important. It would be misleading to regard peer groups exclusively as a source of problems. Positive peer connections can support learning, motivation, social adjustment and achievement, while negative peer pressure may contribute to undesirable behaviour and poorer academic outcomes. A 2025 study of secondary school students in Lagos State, for example, examined peer relationships and group study and found the issue sufficiently important to investigate in relation to students’ socio-psychological adjustment and academic performance.

It is therefore necessary to investigate the nature of peer group influence among students in selected secondary schools in Dekina LGA. Understanding whether peer influence predominantly supports or hinders academic performance and social behaviour can assist teachers, parents, school administrators, counsellors and education authorities in developing appropriate interventions. Such interventions may include peer mentoring, counselling programmes, cooperative learning, positive peer leadership and strategies for reducing harmful peer pressure.

Against this background, this study examines the impact of peer group influence on students’ academic performance and social behaviour in selected secondary schools in Dekina Local Government Area of Kogi State.

1.2 Statement of the Problem

Academic performance and social behaviour are two major indicators of students’ success in secondary education. Schools are expected to provide an environment in which students develop academically while also acquiring appropriate social values, interpersonal skills, discipline and responsible behaviour. However, concerns continue to arise about poor academic performance, truancy, bullying, indiscipline, disrespect for school authorities, poor study habits and other behavioural challenges among some secondary school students.

One possible explanation for these challenges is the influence of peer groups. Adolescents spend a considerable amount of time with classmates and friends, and the attitudes, values and behaviours of these peers may influence their own choices. Students may adopt the study habits, language, attitudes and behavioural patterns of their friends. Where the dominant peer culture encourages academic commitment, students may become more motivated to study and achieve good grades. Conversely, where peers encourage truancy, excessive entertainment, examination malpractice, disobedience or other negative behaviours, students may experience difficulties in maintaining academic commitment and appropriate social conduct.

The problem is complicated by the fact that peer influence is not always visible or easily measured. A student may not be directly forced by friends to behave in a particular way but may change his or her behaviour because of the desire for acceptance or fear of rejection. Students may conform to group expectations in order to maintain friendships. Consequently, some forms of peer pressure may operate indirectly through imitation, social comparison and the desire to belong.

Another dimension of the problem is that peer influence can produce both positive and negative outcomes. Students may form study groups, share educational materials, assist one another with difficult subjects and encourage good attendance. At the same time, students may be influenced to engage in behaviours that interfere with learning. Existing Nigerian evidence supports this dual nature of peer influence. Ukpabi and Akinyemi (2021), for example, reported positive academic, emotional and social benefits associated with peer groups while also identifying the need for counselling where negative peer influence occurs.

There is also evidence that peer influence is associated with academic performance among Nigerian secondary school students. Akinbode and Olasunkanmi (2021) found a significant positive relationship between peer group and academic achievement in their study of public secondary school students in Ogun State. Oladeji (2021) similarly reported a significant relationship between peer influence and academic performance among secondary school students in Ibadan North. These findings indicate that peer relationships deserve attention when explaining differences in students’ academic outcomes.

However, evidence from other locations cannot automatically be generalised to students in Dekina Local Government Area. The social environment, family structures, school conditions, community expectations and patterns of peer interaction may differ considerably across locations. There is therefore a need for local evidence on the nature and extent of peer group influence among students in Dekina.

The problem is particularly significant because evidence from Dekina has already identified student indiscipline as an issue related to academic performance. Enefu et al. investigated the effect of indiscipline on academic performance among secondary school students in Dekina LGA, involving a reported population of 42 secondary schools, 2,503 students and 300 teachers. While indiscipline can result from several factors, peer influence is one possible social mechanism through which students may acquire or reinforce inappropriate behaviour.

Furthermore, insufficient empirical attention to the combined relationship between peer influence, academic performance and social behaviour creates a knowledge gap. Much of the existing literature has concentrated on peer influence and academic achievement, while fewer studies have simultaneously considered academic performance and social behaviour within a specific local government area. The present study therefore seeks to provide evidence on whether and how peer group influence affects students’ academic performance and social behaviour in selected secondary schools in Dekina LGA.

The central problem of this study is therefore that, despite the importance of peer relationships in adolescent development and the evidence that peer influence can affect academic and behavioural outcomes, the extent and direction of this influence among secondary school students in selected schools in Dekina Local Government Area remain insufficiently established. This study is designed to address this problem by examining the impact of peer group influence on students’ academic performance and social behaviour.

1.3 Purpose of the Study

The main purpose of this study is to examine the impact of peer group influence on students’ academic performance and social behaviour in selected secondary schools in Dekina Local Government Area of Kogi State.

Specifically, the study seeks to:

1. examine the extent to which peer group influence affects students’ academic performance in selected secondary schools in Dekina LGA;
2. determine the influence of positive peer relationships on students’ academic performance;
3. examine the influence of negative peer pressure on students’ academic performance;
4. determine the influence of peer groups on students’ social behaviour; and

1.4 Research Questions

The following research questions will guide the study:

1. To what extent does peer group influence affect students’ academic performance in selected secondary schools in Dekina LGA?
2. What influence do positive peer relationships have on students’ academic performance?
3. What influence does negative peer pressure have on students’ academic performance?
4. To what extent do peer groups influence students’ social behaviour?

1.5 Research Hypothesis

The following null hypothesis will be tested at 0.05 level of significance:

H₀: There is no significant relationship between peer group influence and students’ academic performance and social behaviour in selected secondary schools in Dekina Local Government Area of Kogi State.

1.6 Significance of the Study

The study will be useful to students, parents, teachers, school administrators, guidance counsellors, government agencies, policymakers and researchers.

Students: The study will help students understand how friendship networks and peer pressure can affect their academic and social lives. It may encourage students to develop relationships with peers who support positive academic and behavioural development.

Parents and Guardians: The findings may help parents understand the importance of monitoring their children’s friendships without unnecessarily restricting healthy social relationships. Parents may also become more aware of behavioural changes that could indicate negative peer influence.

Teachers: Teachers may gain a better understanding of the role of peer relationships in students’ classroom behaviour and academic engagement. This may enable them to identify students who require additional academic, social or behavioural support.

Guidance Counsellors: The findings may provide useful information for designing counselling programmes aimed at preventing negative peer pressure. Counsellors may use peer mentoring, group counselling and social-skills programmes to encourage healthy peer relationships.

School Administrators: School administrators may use the findings to develop policies and programmes that promote positive peer interaction. Peer leadership schemes, academic clubs, mentoring programmes and cooperative learning activities may be strengthened where appropriate.

Government and Educational Authorities: The study may provide evidence that can assist education authorities in designing programmes addressing student discipline, academic performance and adolescent social development in secondary schools.

Researchers: The study will add to the existing body of literature on peer influence, academic performance and social behaviour in Nigeria. It may also serve as a reference point for researchers who wish to conduct related studies in other local government areas or states.

1.7 Scope of the Study

The study focuses on the impact of peer group influence on students’ academic performance and social behaviour in selected secondary schools in Dekina Local Government Area of Kogi State.

The study covers students enrolled in the selected secondary schools within the study area. The independent variable is peer group influence, which will be examined in terms of positive peer influence, negative peer pressure, peer academic support, conformity and peer behavioural modelling. The dependent variables are students’ academic performance and social behaviour.

Academic performance will be considered in terms of students’ achievement in school-related assessments, while social behaviour will include interpersonal relationships, cooperation, respect for school rules, discipline, communication, bullying, aggression and other relevant behavioural characteristics.

The study is limited to selected secondary schools in Dekina LGA and does not seek to generalise its findings automatically to all secondary schools in Kogi State or Nigeria.
