The speaker of the speech ,Do Schools Kill Creativity, by Ken Robinson, a University professor contends that schools kill creativity. He brings about his own perspective towards the topic using real life examples he has witnessed and experienced. He speaks to an audience with the intention of convincing them that students loose creativity as they continue through today school system. Robinson proves that schools kill creativity by explaining the school system and using real life examples. He argues that all schools have the same hierarchy of subjects with language and mathematics at the the top and that the education system is based on academic ability, pretty much nothing else. He says that people are kept away from things they enjoy or things they are talented at.
Robinson speaks directly to an audience. The speech is also targeted towards people of the education system such as teachers, principles, university professors, etc. It is also targeted towards all people in general. Robinson is serious as he speaks about this argument however he does joke a little to lighten the audience. He uses a bit of sarcasm which I found pretty funny. He also uses things like metaphors and he has a subtle tone.
