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 space of the school (walls, floor, corridor, windows, doors, etc.) is designed as a learning resource. In this setup, learners interact independently with the environment at their own pace, exploring and learning without continuous direct instruction from a teacher.

Let us analyze the given options:

1. Teaching Aid: These are tools used primarily by teachers to facilitate teaching (e.g., charts, chalkboards, models), putting the teacher in the active role.

2. Building as a Learning Aid: This environment acts as a self-directed learning space where children can explore, observe, and learn autonomously, making the role of the learner that of an independent learner.

3. Teaching learning materials: These are resources used in the instructional process, which can be teacher-driven or student-driven depending on usage, but do not inherently define an independent learning environment like BALA does.

4. Integrated materials: These are combined resources across subjects/topics to provide holistic learning, but they still usually require instructional guidance.

Therefore, Building as a Learning Aid best promotes and supports the role of an independent learner.
