The 3 Layers of Environmental Education in Schools
Environmental education in schools can be understood through three important dimensions.
- Curriculum (What Students Learn)
- Practice (What Students Do)
- School Culture (What Students Experience)
Layer 1: Curriculum
What Do Students Learn?
The first layer of environmental education is the school curriculum. This includes the environmental topics that students learn through formal classroom teaching. These topics may appear in subjects such as science, geography or agriculture where students may learn about ecosystems and biodiversity, climate change, pollution and waste management, conservation of natural resources, sustainable farming and land use
Through curriculum-based learning, students develop knowledge and understanding of environmental issues. However, theoretical knowledge alone is not always enough to change behavior. Students may understand environmental problems but still feel disconnected from them if they do not have opportunities to apply what they learn.
For this reason, environmental education must extend beyond the curriculum.
Layer 2: Practice
What Do Students Do?
The second layer of environmental education is practice. Practice refers to the activities and experiences that allow students to apply environmental knowledge in real situations.
Examples include:
- tree planting activities
- school gardens or farms
- environmental clubs
- recycling programs
- school clean-up campaigns
Through these activities, students develop skills and responsibility. They begin to see that environmental protection is something they can actively participate in. For example, students who learn about plant growth in science may also participate in planting crops or trees in the school environment. This helps them connect theoretical knowledge with real-world experience.
Practice transforms environmental education from information into action.
Layer 3: School Culture
What Do Students Experience?
The third layer of environmental education is school culture. School culture refers to the values, behaviors, and environment that shape students’ daily experiences within the school. Students learn not only from lessons and activities, but also from the messages communicated by the school environment.
For example, students observe:
- whether the school environment is clean
- whether trees and green spaces are valued
- whether waste is managed responsibly
- whether teachers model environmental responsibility
- whether sustainability is encouraged in school activities
When environmental values are reflected in school culture, students begin to see environmental responsibility as a normal and expected part of community life.
School culture helps transform environmental education into a shared value within the school community.
Why Environmental Knowledge Does Not Always Lead to Environmental Action
In many schools, environmental topics are already part of the curriculum. Students learn about climate change, pollution, conservation, and the importance of protecting natural resources.
However, Learning about the environment does not always lead to caring for the environment.
Students may successfully pass examinations on environmental topics, yet their daily behaviors may not reflect environmental responsibility.
This raises an important question for educators:
Why does environmental knowledge sometimes fail to translate into environmental action?
To understand this, it is important to explore the difference between curriculum learning and practical experience.
Curriculum-Based Environmental Education
Curriculum-based environmental education refers to the structured teaching of environmental topics within formal lessons. This learning typically takes place in classrooms through teacher instruction, textbooks, class discussions, assignments and tests.
Through these lessons, students gain knowledge and theoretical understanding of environmental issues. However, this form of learning often remains abstract. Students understand environmental problems intellectually, but they may not yet see how those issues connect to their own daily actions.
Practice-Based Environmental Education
Practice-based environmental education focuses on learning through action and participation. Instead of only hearing about environmental issues, students become actively involved in environmental activities. These activities allow students to experience environmental responsibility directly. Students begin to see that their actions can influence the environment around them.
The Knowledge-Action Gap
The difference between curriculum learning and practice-based learning often creates what educators call the Knowledge-Action gap.
This gap occurs when students understand environmental problems but do not develop habits or behaviors that protect the environment.
For example, students may learn in class that plastic pollution harms ecosystems, yet they may continue to litter within the school compound.
This happens because behavior is not shaped by knowledge alone.
Behavior develops through repeated experiences, participation, and social influence.
Why Practice Matters in Environmental Education
Practice-based environmental education helps bridge the knowledge-action gap in several ways.
1. It Makes Learning Concrete
Environmental concepts become easier to understand when students experience them directly.
For example, when students plant crops or trees, they begin to understand how plants grow, how soil supports life and why water and care are necessary for survival.
These experiences help transform abstract ideas into real understanding.
2. It Builds Responsibility
When students participate in environmental activities, they begin to feel a sense of ownership and responsibility.
When a student or a group of students plant some trees, they also take on the responsibility of protecting, growing and pruning the tree through out their school years, as a result they become active contributors to environmental wellbeing.
3. It Develops Habits
Environmental responsibility is often shaped through daily habits. Activities such as separating waste, caring for plants, and maintaining clean surroundings help students develop habits that support sustainability. Over time, these habits become part of students’ everyday behavior.
