He would always explain things in terms that the students were able to relate to and would be able to give back feed back. We all know that most teacher do try to get your attention and the good ones are those that keep asking questions and keep the interest of the students. So in many ways being an entertainer is part of being a teacher, you want kids to want to come to your class as they want to go to a concert of a party. A place that is not all about trying to figure out what the teacher is saying but a place to develop your knowledge. A teacher is an entertainer in a sense.
Good teachers have to find a way to motivate students to learn the material.
Entertaining the class does not mean that the teacher has to have a five minute stand up act at the beginning then role into a few skits that tie into the unit. The teachers have to find a way to make what the students are supposed to be learning interesting. Cheryl, your view of the teacher as an entertainer seems to be somebody on stage making people laugh and inspiring the students to no end. Ideally that would be nice, but a teacher as an entertainer in my opinion is presenting the material in such a way that it is interesting to the students. Granted, grammar is not the most exciting material to cover, but using a wide variety of activities will help ease the monotony of all the varying verb conjugations, prepositional rules and so on.
