As a teacher you cannot assume anything about your students. Each student comes in with a different background, a different history than any other student. It is the educators job to find out about each student and what will make the education provided to them relevant. Learners are similar in that they all can learn however learners have many differences. They come from different places in life so what they consider relevant varies by individual.
Learners have many different intelligences.
Some may excel in math, but not reading, while others may learn orally and others learn visually. It is the teacher's responsibility to recognize these differences and work with them. Learning is to gain knowledge, understanding, or skill by study or experience. Learning occurs by experience. When a student learns something they possess what the learned and can apply it in life.
