Linguistic structure and educational achievement in second language acquisition

The distinction between basic interpersonal communication skills (BICS) and cognitive-academic language proficiency (CALP) highlights the challenges students face in educational contexts. CALP requires advanced vocabulary, coherence, and the ability to navigate complex language structures, which are crucial for academic success. Research involving Turkish-German and Russian-German students reveals a significant link between their ability to articulate mathematical problems and their success in solving them, emphasizing the importance of CALP in educational achievement.
