Learning a foreign language aids brain development by engaging both sides of the brain and supporting cognitive development, especially when learned early in life. A study of 67 sixth-graders learning French found that those who studied the language longest performed best on cognitive tasks. Teaching foreign languages fosters cultural competence by helping students understand and communicate with diverse cultures, which is important for reducing issues like misunderstandings due to differing cultural beliefs and communication styles. Being proficient in another language also provides professional advantages and prepares students for an increasingly global workforce and multicultural society.
