​What is necessary to remove learning related mistakes and lacunae?​

Correct option is D

Correct answer is (D) Remedial teaching.

Explanation:
To remove learning-related mistakes and lacunae, remedial teaching is necessary. Remedial teaching focuses on addressing individual learning gaps, providing extra support and tailored instruction to help students overcome difficulties and master concepts they may have missed or not fully understood. It is specifically designed to help students who are struggling and provides them with the opportunity to catch up with the rest of the class.

Other options:

• (A) Achievement testing: While achievement tests help assess students' learning, they don't directly address the mistakes or lacunae in learning. Tests are evaluative rather than corrective.

• (B) Micro teaching: Micro teaching involves teaching in a controlled, small-scale setting to improve teaching skills, but it doesn't specifically target the learning gaps of students.

• (C) Revision: Revision helps reinforce what has already been learned, but it may not be sufficient on its own to address specific learning difficulties or mistakes.

Examination booster:
When preparing for questions about improving student learning, remember that remedial teaching is the most direct approach to helping students overcome difficulties, as it focuses on personalized, corrective instruction.

Additional knowledge:
Remedial teaching often involves identifying the root causes of mistakes (such as misunderstanding a concept) and providing targeted exercises or strategies to correct them. It can take place in one-on-one settings or in small groups.
