Several factors affect language learners' use of language learning strategies (LLS), including: 1) Younger learners tend to use more LLS than older beginners, and motivation is the most significant factor influencing LLS choice. 2) Females generally use more LLS than males, especially social and metacognitive strategies. 3) More proficient learners apply a wider variety of LLS more frequently than lower proficiency learners. 4) Students from wealthier families deploy more LLS outside of class and for exams due to greater resources to support language learning.
