1) There are two different learning styles, one is the relational learning style and the other one is the analytical learning style. In the relational learning style people learn the whole first and then little parts, whereby in the analytical learning style people learn first the smaller fundamental parts of something before they learn the whole. The analytical style is more often used in western schools but I think that schools could also work in a relational style. Even though the relational style is not that common it would work in schools in which students are doing a lot of experiments or games to learn. A student has to understand the whole purpose first before he or she can start an experiment or game. In some cases analytical learning is necessary, because the little parts have to get learned first. An example for analytical learning is the learning of golf, because it is not possible that somebody who does not know how to hit a golf ball is able to play a 18 hole golf course.
2) When I would be a social worker I would give an advice to parents that violent media and video games can cause aggression by their children. When children are playing these violent video games or watch violent media they get used to the violence and learn to think that the world is violent. After they get used to the violence they start to act aggressive, because they think it is normal to act aggressive like the characters in the violent video games or the media do. Because children learn a lot by imitation they try to copy the characters from the movies and the games, which are usually aggressive and use violence. Certainly it is hard for parents to control what movies their children are watching and what games they are playing, but it is important that they keep to look at it because it can have serious affects on their children.
