The importance of the mother tongue

This page for parents explains why it is so important for their child to use and develop the mother tongue.

Introduction

There is a lot of advice to parents of ESL students elsewhere on these pages. However, the most important message can be summarized in one sentence:

ESL students in international schools learn English more quickly and effectively if they maintain and develop their proficiency in the mother tongue.

How the mother tongue helps the learning of English

Research* has shown that many skills acquired in the first language can be transferred to the second language. So, for example, if your child has developed good reading skills in Korean, she is likely to be able to apply these skills when reading English.

One useful reading skill is the ability to guess the meaning of unfamiliar words from context. Another one is the ability to decide which new words in a text are important to look up in the dictionary and which words can safely be ignored. For this reason it helps if you can encourage your child to read good fiction and non-fiction in her own language.

Similarly, the skills of being able to plan out a piece of writing or develop an argument in a persuasive essay can be applied in the second language once they have been learned in the first language.

Krashen has researched extensively in the field of second language acquisition. He states:

"In early stages [reading in the first language] can profoundly accelerate the development of reading ability in the second language."

This is true because:

  • reading skills transfer from language one to language two
  • reading provides knowledge of the world that makes second-language texts more comprehensible
  • the pleasure of the reading habit itself transfers to the second language

Other reasons for developing mother tongue proficiency

Firstly, many children in international schools plan to return to their home country at some point to continue their education there. This is a strong reason to make sure they do not have gaps in mother tongue language or cognitive development.

And secondly, ESL students who turn against or otherwise neglect their mother tongue can often suffer from problems of identity loss or alienation from their parents, and from their grandparents or other family members in their home country.

Ways to develop the mother tongue proficiency

For some students, developing mother tongue proficiency is easier because they have lessons each week in their native language. For students who are not in this fortunate position, there is still much that can be done to maintain the mother tongue.

For example, parents can make sure that they have good reference books or textbooks at home - in the native language. Students should be encouraged to read good literature and to discuss school work. Some of the long summer vacation could be devoted to mother-tongue learning and reading.

With one big and one small wheel (one good and one not so good language) you can go farther and faster.

With two equal-sized wheels (two strong languages) you can comfortably go anywhere you want!
