2 tips that would apply to effectively presenting in a classroom situation

When presenting anything in any situation I think that originality is very important. Everyone expects the expected which usually translates into something mudain instead of something spontaneous. It is fun, in my opinion, to be creative and think of new ideas/ways to present a topic. When I am being presented to, I look for something that jumped out at me and something that caught me off guard.

The second thing that is effective in any presentation is creating something along the way in accordance to the way your audience is responding. This does not mean that a presentation shouldn't be planned out and executed accordingly but if what you have planned and presented isn't getting a positive response from the audience then nothing is going to resonate after the presentation is over. It makes sense to me to play off of what your audience gives you. If they are not responding at all then something impromptu would be appropriate.
