How can I use knowledge of the learner to be a better teacher?

I can use knowledge of the learner to be a better teacher by using that knowledge in assignments. I feel that it is very important to ask students about what is the best way for them to retain information. Each student learns differently and because of this I will have to adjust assignments. I will also be aware of students who are not as proficient in the English language because it will make class harder for them.
