Comparing and Contrasting First and Second Language Acquisition: Implications for Language Teachers

In an attempt to understand and explain first language (L1) acquisition and second language (L2) acquisition scholars have put forward many theories. These theories can aid language teachers to understand language learning and to assist their students in their language learning process. The current paper will first look at the similarities between the L1 and L2 acquisition. Then, the differences will be outlined. In the last part of the paper the implications of these findings for foreign language teachers will be discussed.
