For me a teacher shouldn't need to be a entertainers. IA better teacher should understand and know how to make his/her topic more interesting and friendly to it's listener. To make a lesson to be more interesting is to show what's the relevance and its application to the topic. And toTo make a lesson more friendlyto be lively is to use some visual toolsaids to be easily understood and make some interaction to help picture the purpose of the topic in that way listeners to keep conversation livelyare not bored and help there imagination guided.
