Should teachers use more games to teach students?

Yes, Yes, Yes and YES!

Experimental learning is a very effective method to use when learning. The learner learns more effectively because you relate the ionfomration to something that is fun and that they understand and can relate to.

Real learning happens when the learners are involved in their own learnings and this can be done through games, role-plays etc.

Try it with a child . Explain to them how to brush their teeth. Would a 2 year old be able to unerstand what to do from the start? No, they wont.

But show them how to do it. They will grasp it must better!
