Curriculum construction plays a vital role in shaping how students gradually acquire knowledge. Over time, educators have developed different approaches to designing a curriculum so that learning becomes meaningful, structured, and progressive.

The following are the key methods most commonly used:

Concentric Method

The word concentric means “sharing a common centre.” In this approach, a subject is built around a central theme, with related subtopics gradually introduced in increasing depth and complexity.

• Learning progresses step by step: from simple to complex, known to unknown, and easy to difficult.
• Each new stage builds upon previous knowledge, making learning continuous and interconnected.
• The teaching approach changes according to the learner’s maturity and comprehension level.

Examples:

• Natural Vegetation taught in Classes V, IX, and X at progressively deeper levels.
• Rocks studied in Classes V, VII, and VIII.
• Population covered in Classes V and X.
• Water resources explored from Class V to IX.

Regional Method

This method focuses on studying the world region by region. Students begin with smaller areas and expand their understanding to larger geographical units.

• Progression: State → Country → Neighbouring Countries → Natural Regions → Continents.
• Each region is studied in terms of its location, boundaries, climate, vegetation, resources, human life, culture, trade, and economy.
• Use of maps, charts, models, and other teaching aids makes the study more engaging and memorable.

Examples:
In Class VII, learners may study regions such as Japan, Italy, South Africa, Tanzania, or the USA.

Unit or Topical Method

This approach combines features of both concentric and regional methods. The syllabus is broken into topics or units, each of which is assigned to a particular class level.

• Broad subjects are split into smaller, manageable units.
• Learners focus on one topic at a time, encouraging deeper understanding and stronger retention.
• The method follows a natural progression from the familiar to the unfamiliar.

Example:
While studying Water Bodies, the sequence may move from pond → lake → river → sea → bay → strait → gulf → ocean, with each studied as a distinct unit.

Mixed or Eclectic Method

The term eclectic means “drawing from diverse sources.” This method is comprehensive and flexible, combining the strengths of various approaches.

• It is free in nature and not bound to one rigid style.
• Elements of concentric, regional, and topical methods are integrated to provide a balanced curriculum.
• Students are exposed to multiple perspectives, making learning broader and more adaptable.

Example:
The Class X syllabus often reflects an eclectic structure, blending different methods for effective coverage.

Each curriculum construction method has its own strengths. While the concentric method builds knowledge step by step, the regional method expands global awareness. The unit method ensures focused study, and the eclectic method provides a holistic blend. Together, these approaches help design a curriculum that caters to diverse learning needs and prepares students for higher levels of understanding.
