Answer :
The relationship between a student's first-and second language acquisitions is not about discontinuing or limiting cognitive development in L1, but rather, students who received formal schooling in L1 do better at acquiring L2 than students with no schooling in L1.
The acquisition of a second language for students who already have a first language is a complex process.
However, research shows that cognitive development in L1 does not need to be discontinued or limited for academic success in L2.
Instead, students who received formal schooling in L1 have an advantage when acquiring L2. This advantage is due to the transfer of certain cognitive skills like problem-solving, critical thinking, and meta-linguistic awareness from L1 to L2.
Additionally, students who learn to read and write in L1 have an easier time learning to read and write in L2, as they possess a basic understanding of how written language works.
Therefore, rather than limiting L1, educators should focus on building upon a student's L1 skills to support their acquisition of L2 at an academic level.
