What´s motivation? well, it is the internal process that activates, guides and mantains behavior over time. Without motivation, is morre difficult to learn, beacuase it determines how much the student will learn.
this motivation is produced by curiosity or interest, or external influences like other people.
using energy in for doing things, invest time and maybe if they like the activity, spend a good time by learning. There are many factors that motivate or dismotivate the student. Some of them are: age, personality, abilities, the method they use for learning, or even a reward, a prize, also pressure, fear. There are a lot, but the best thing is that this interest must come from the student, something internal. To learn, not because he or she will receive something in exchange, but of the simple reason to learn and to know.
