Teaching Materials in EVS
Charts, Models, Multimedia and Field-Based Resources
---
Overview
Teaching materials are the bridge between abstract environmental concepts and a child's concrete understanding. In Environmental Studies, where learning is rooted in observation, exploration and real-life experience, the choice and use of teaching materials directly determines whether children merely memorise facts or truly comprehend their surroundings.
For GTET Paper-1, questions on teaching materials appear regularly under EVS Pedagogy. You must understand not just what materials exist, but why specific materials suit specific topics, how to use them effectively, and their limitations. The syllabus emphasises hands-on, activity-based learning aligned with NCF-2005 principles—so expect questions testing your ability to match materials to learning objectives.
Mastery here requires knowing the four main categories—charts, models, multimedia and field-based resources—and understanding when each is most appropriate for primary-level EVS instruction.

Key Concepts
- **Concrete to Abstract Progression**: Young children (ages 6-11) learn best when instruction moves from real objects to pictures to symbols. Teaching materials must follow this sequence—real plants before plant diagrams.
- **Multi-sensory Learning**: Effective EVS materials engage multiple senses. A model of the water cycle that children can touch and manipulate creates stronger memory traces than a chart alone.
- **Local Relevance**: NCF-2005 emphasises that EVS materials should reflect the child's immediate environment. A chart showing coconut trees is appropriate in coastal Gujarat; one showing apple orchards suits Kashmir.
- **Activity-Based Approach**: Materials should enable doing, not just viewing. Charts are passive; models children assemble, field visits where they collect specimens—these are active.
- **Low-Cost and Improvised Materials**: GTET often asks about teacher-made or locally available materials. Knowing how to create effective teaching aids from everyday items is valued.
- **Integration Principle**: EVS integrates science and social studies. Materials should reflect this—a market visit teaches both economics (prices, trade) and science (food sources, preservation).
- **Age-Appropriateness**: Materials for Class 1-2 should be simpler, more colourful and tactile. Classes 3-5 can handle more detailed charts and complex models.
