Mother Tongue Multilingual Education , The Research Is Clear — Teach Children in Their Home Language First, Then Add the Others

Imagine a classroom in Sindh, Pakistan, where a group of seven-year-olds who speak Sindhi at home and have no exposure to any other language outside of their immediate family are being taught mathematics in English by the teacher. The kids are seated in silence. They’re not studying math. They are attempting to decipher the teacher’s noises, and the two tasks—mathematics and language acquisition—are vying for the same cognitive bandwidth in a brain that hasn’t yet fully developed either ability.

The instructor, who has received training in a second language herself, is following instructions. Because the medium of education expected a familiarity that didn’t there, the kids are falling behind on material that will be important for years without their fault. Mother tongue-based multilingual education was created to avoid this situation in a variety of contexts and places.

The framework, known as MTB-MLE and constantly supported by UNESCO in all of its educational projects, is based on the surprisingly straightforward idea that children learn best when they begin in a language they are already familiar with. Children who are also navigating a new instructional language fall furthest behind during the early years of formal schooling, when core literacy and numeracy skills are built.

Students taught in their native tongue in the early grades comprehend science, arithmetic, and reading ideas much more quickly than their classmates taught in a dominant national or international language from the first day of school, according to research conducted in a variety of nations and linguistic circumstances. If nothing is done, the gap tends to expand and opens early.

This shift is purposefully structured by the “language ladder” approach that the majority of instructors advocate. The mother tongue—Punjabi, Saraiki, Tagalog, Amharic, or whatever the home language is for a particular community—is used as the primary language of teaching in grades Pre-K through Three. Alongside the mother tongue, national and regional languages are introduced in grades four through seven, with the balance gradually shifting.

Students should be proficient in the predominant national or international language by the time they reach Grade Eight. Because the basic cognitive architecture is already established, literacy and conceptual skills acquired in the first language transfer effectively to succeeding languages, providing pretty solid evidence for this sequence. The idea does not begin anew, but the language does.

It makes sense that parents in many areas are opposed to this concept, and it is important to consider this rather than brush it off. Every year spent on Punjabi or Sindhi instruction can feel like a year’s worth of English that was not given in places where English is seen as the key to economic opportunity. That computation is not illogical; rather, it is a genuine structural pressure about the language that leads to career opportunities.

The long-term costs of students who enter Grade Four or Five with weak reading foundations in any language because their early education was provided in a language they didn’t comprehend are often underestimated. Some of the most well-documented evidence on this topic comes from the countrywide implementation of MTB-MLE in the Philippines in 2012: early Grade Three outcomes in reading and mathematics increased where the program was administered faithfully.

Considering the body of evidence supporting this model, it seems more difficult to determine whether the systems needed to put it into practice—trained teachers, suitable textbooks, and political will across linguistically diverse regions—can be put together and maintained. For decades, UNESCO has maintained this position. The discrepancy between what most educational systems offer and what the data suggests is not primarily a knowledge issue.
