Mother Tongue and L2 English Learners

I remember the time when I was told that in an English class the use of the mother tongue cannot be acceptable because it is not beneficial for students to learn a foreign language. So I asked to myself, why? Because I knew that you cannot speak in Spanish all the time, but “never”? In my classes I accept it for some activities and for others I do not. According to Davis Carless “Students use of the mother tongue in the task-based classroom”, the use of the native language or mother tongue (MT) is quite complex because it could be beneficial for learners but, at the same time, it could not. In general, the use of MT is stigmatized by some methods, and teachers who cannot handle a class in the target language (TL) feel frustrated by the overuse of the students’ first language. However, as the writer claims, by taking into account the type of tasks we give to our students we can analize which are the ones that imply a positive effect on the second language acquisition and the ones that imply negative effects. Thus, teachers will be able to handle a task-based class with both languages in interaction.

Firstly, Carless argues that the use of MT may have positive and negative effects on second language acquisition. Positive effects seem to “serve social and cognitive functions, including the construction of scaffolded assistance and create through collaborative dialogue the opportunity for language acquisition to take place.” In fact, through group works, in which students do not need to speak in English all the time, they can elaborate hypothesis or predictions about the TL in their own language, serving as a base to produce a significative output. On the other hand, negative effects seem to “undermine the psycholinguistic rationale for task-based interaction as stretching student interlanguage through the process of engaging
