Researchers like Grenfell and Harris (1994) observed that older students use more effective learning strategies than younger students. In particular, older students have better memory capacity, more efficient ways of organizing information, greater ability to concentrate and attention, more systematic study and preparation habits, and the ability to make complex cognitive processes – skills that all related to language learning strategies.
