Question

........... are used to help the child to comprehend the self-error without seeking any help from adults.

Hint:

Self-correcting materials = independent error checking.

Answer 1

The correct term here is Self-correcting materials.
Self-correcting materials are specially designed learning aids that allow children to check and correct their own work independently.
These materials promote self-learning, responsibility, and problem-solving skills.
Examples include puzzles with matching pieces, Montessori materials like knobbed cylinders, or cards with answers on the reverse side.
When using these, children get immediate feedback and learn through trial and error, building confidence in their abilities.
They help reduce over-reliance on teachers or adults for correction, encouraging autonomy and deeper understanding.
