one of my classes involves teaching beginner and elementary learners in the same classroom. Naturally, there's a large difference between the elementary learner and the beginner students. The elementary learner considers that his ability to communicate is stronger than his other peers, and he's right. However, this elementary learner's weakness is his reading and writing ability, unlike the other learners being able to read and write but unable to communicate. Unfortunately, he initially didn't see the benefit of improving his reading and writing until I explained to him why this was.
Then I realised. Sometimes, it is better to speak with students rather than telling them what is best for them. In that way, you can work with the student.
