In which of the following the role of the learner is that of an independent learner ?

The correct option is Building as a Learning Aid.

Explanation:

Building as a Learning Aid (BaLA) is an educational concept where the physical environment of a school (such as walls, floors, doors, staircases, and corridors) is designed and used as a self-learning resource for children.

In this approach:

1. The environment contains built-in learning elements (e.g., measuring scales on pillars, geometrical patterns on floors, interactive wall puzzles).

2. Learners can explore, observe, and engage with these features at their own pace without needing continuous teacher intervention.

3. Thus, the role of the child transitions from a passive listener to an independent learner who actively constructs knowledge through self-guided exploration.

In contrast, standard teaching aids and teaching-learning materials are generally selected and mediated by the teacher during instruction.
