Project – Teachers’ Role in Promoting Environmental Sustainability through Classroom Instruction in Public Secondary Schools in Kaduna State

CHAPTER ONE
INTRODUCTION

1.1 Background of the Study

Environmental sustainability has become one of the most urgent global concerns of the 21st century. The increasing rate of environmental degradation—manifested in deforestation, desertification, pollution, loss of biodiversity, and climate change—poses a major threat to the survival and development of humanity (UNESCO, 2021). These challenges are particularly severe in developing nations such as Nigeria, where rapid urbanization, poor waste management, overexploitation of natural resources, and inadequate environmental awareness have intensified ecological problems (Akinbode, 2002; Nwafor, 2006).

Education has long been recognized as a powerful tool for fostering environmental awareness and promoting sustainable practices. According to UNESCO (1977), environmental education is the process of recognizing values and clarifying concepts to develop skills and attitudes necessary to understand and appreciate the interrelatedness between humans, their culture, and their biophysical surroundings. In this regard, teachers play a vital role as agents of change, equipping students with the knowledge, attitudes, and skills necessary to make informed decisions and take responsible actions toward environmental sustainability (Tilbury, 1995; Palmer, 1998).

In Nigeria, the National Policy on Education (Federal Ministry of Education, 2013) acknowledges the role of education in achieving national development goals, including environmental sustainability. The policy emphasizes the integration of environmental concepts across subjects at all levels of education. Consequently, environmental education is expected to be infused into subjects such as Geography, Integrated Science, Agricultural Science, Civic Education, and Social Studies in secondary schools. However, the extent to which this integration has translated into practical teaching and student behavioral change remains uncertain (Okebukola, 2001; Ajiboye & Olatundun, 2010).

Teachers, as the primary implementers of the curriculum, occupy a central position in advancing the goals of environmental sustainability. Their knowledge, pedagogical approaches, and attitudes toward environmental issues significantly influence how students understand and respond to such issues (Ogunyemi & Akinbode, 2011). Effective environmental instruction goes beyond imparting theoretical knowledge; it involves engaging students in problem-solving activities, field experiences, and community-based environmental projects that nurture a sense of responsibility and stewardship for the environment (Sterling, 2001).

In Kaduna State, like many other parts of Northern Nigeria, environmental problems such as soil erosion, desert encroachment, deforestation, flooding, and poor waste disposal are common (Jatau, 2018). These problems have adverse effects on agriculture, health, and livelihoods. Public secondary schools, being critical institutions for shaping young minds, present a unique platform for instilling sustainable environmental values and practices. However, the success of such efforts depends largely on teachers’ competence, motivation, and commitment to integrating sustainability principles into their classroom instruction (Buba, 2019).

Despite several policy initiatives such as the National Environmental Standards and Regulations Enforcement Agency (NESREA) Act of 2007 and the National Environmental Education Policy Framework, implementation at the grassroots level remains weak, especially in public schools (Adara, 2015). Teachers often face challenges such as inadequate instructional materials, limited professional development, overcrowded classrooms, and insufficient institutional support, all of which hinder their ability to promote environmental sustainability effectively (Nwagbo & Uzoegwu, 2011).

Therefore, there is a pressing need to examine teachers’ role in promoting environmental sustainability through classroom instruction in public secondary schools in Kaduna State. Understanding teachers’ knowledge, attitudes, and instructional practices can provide valuable insights into how education can be leveraged to address environmental challenges and promote sustainable development in Nigeria.

1.2 Statement of the Problem

Environmental degradation continues to worsen in Nigeria despite the inclusion of environmental education in school curricula and government efforts to promote sustainability. In Kaduna State, the effects of desertification, deforestation, flooding, and waste mismanagement are increasingly evident (Jatau, 2018). These issues highlight a persistent gap between environmental awareness and actual sustainable behavior among citizens, particularly young learners who are expected to be future environmental stewards.

Public secondary schools are strategically positioned to influence students’ environmental consciousness through classroom instruction. However, observations and existing literature suggest that environmental education is often treated superficially or confined to theoretical discussions without corresponding experiential learning or community engagement (Okebukola, 2001; Omoogun & Odok, 2013). Many teachers lack adequate training in environmental education, leading to a weak integration of sustainability themes into teaching practices (Ogunyemi & Akinbode, 2011).

Furthermore, the emphasis on examination-oriented learning, overcrowded curricula, and limited instructional resources often prevents teachers from exploring environmental issues in depth (Ajiboye & Olatundun, 2010). As a result, students may graduate with limited understanding of how their actions impact the environment and with little motivation to adopt sustainable lifestyles.

The problem, therefore, lies not in the absence of environmental education policies, but in the effectiveness of teachers’ instructional roles in translating these policies into meaningful learning experiences. It becomes crucial to investigate how teachers in Kaduna State’s public secondary schools promote environmental sustainability through classroom instruction, what teaching strategies they employ, and what challenges they face in implementing these practices.

This study seeks to bridge this gap by assessing the extent to which teachers contribute to promoting environmental sustainability through classroom instruction and by identifying factors that enhance or hinder effective environmental teaching in public secondary schools in Kaduna State.

1.3 Objectives of the Study

The main objective of this study is to investigate the role of teachers in promoting environmental sustainability through classroom instruction in public secondary schools in Kaduna State. Specifically, the study aims to:

1. Examine teachers’ level of awareness and knowledge of environmental sustainability concepts.

2. Identify the instructional strategies used by teachers to promote environmental sustainability in the classroom.

3. Determine the extent to which teachers integrate environmental sustainability topics into their teaching practices.

4. Investigate the challenges faced by teachers in implementing environmental education in public secondary schools.

1.4 Research Questions

1. What is the level of teachers’ awareness and knowledge of environmental sustainability concepts in public secondary schools in Kaduna State?

2. What instructional strategies do teachers employ to promote environmental sustainability through classroom instruction?

3. To what extent do teachers integrate environmental sustainability concepts into their classroom teaching?

4. What challenges do teachers face in promoting environmental sustainability in public secondary schools in Kaduna State?

1.5 Research Hypothesis

H₀: Teachers’ classroom instruction has no significant influence on the promotion of environmental sustainability among students in public secondary schools in Kaduna State.

1.6 Significance of the Study

This study is significant for several reasons. It contributes to the growing discourse on environmental sustainability and education in Nigeria by emphasizing the central role of teachers in shaping environmentally conscious citizens. The findings will provide useful insights for educational policymakers in reviewing the implementation of environmental education within the national curriculum.

For teachers, the study highlights effective pedagogical strategies that can enhance environmental teaching and foster sustainable behaviors among students. Teacher training institutions and curriculum developers can also benefit from the findings by incorporating environmental sustainability into teacher education programs.

Additionally, the study will assist school administrators in developing initiatives and extracurricular programs that support environmental learning. Ultimately, the research supports the realization of Sustainable Development Goal 4 (Quality Education) and Goal 13 (Climate Action) by fostering education that promotes sustainable lifestyles and responsible environmental behavior.
