In 2009, the Department of Education (DepEd) recognized the benefits of teaching children using their mother tongue or first language. Local and international research has found that children learn to speak, read, and write more quickly in their first language, and can pick up a second and third language more easily if taught in their first language. In the same way, they acquire other academic competencies more quickly, particularly in science and math.
