Which one of the following statements is correct?

Correct statement: Mother tongue must be made the medium of instruction at the primary stage as children come to school with an existing vocabulary and it helps the quality of their learning.

Why this is correct:

• Facilitates comprehension and concept formation because children understand instruction in a familiar language.

• Supports participation and confidence in early schooling, improving overall learning outcomes.

• Provides a strong foundation for later learning of additional languages and subject matter.

Why the other statements are not the best choice:

• Saying the three-language formula will necessarily create complex problems is too general; while implementation can be challenging, it is a policy aimed at promoting multilingual competence and can work well with adequate planning and resources.

• Noting difficulty in finding teachers who can use multilingual approaches highlights a real operational challenge, but this is a practical constraint rather than the primary principle governing medium of instruction.

• The claim that children cannot learn two or more languages at a time is incorrect; young children are capable of acquiring multiple languages concurrently when exposed appropriately.

Overall, mother-tongue instruction at the primary stage is supported because it enhances understanding and learning, while other statements either overgeneralize challenges or state misconceptions.
