Concept:The spiral approach in curriculum design, as promoted by NCF 2005, means that topics are revisited at different grades with increasing depth and difficulty. This helps students build on prior knowledge and master complex ideas gradually.
Explanation:- The spiral approach is not about teaching all concepts at once or introducing completely new topics each year.
- It is also not simply repeating the same content without any progression.
- The best example is where concepts are arranged in increasing order of difficulty, and previously taught concepts are briefly revisited before moving ahead.
- For instance, in early grades, students learn basic fractions; later they learn operations with fractions; finally, they apply fractions in real-life problems.
- This method ensures continuous reinforcement and logical progression of learning.
- Option B correctly describes this approach: including concepts in increasing order of difficulty by briefly revisiting concepts taught previously.
Answer:Option B: including concepts in the increasing order of difficulty by briefly revisiting concepts taught previously.
