Presentation Technique

Do you know how to make a presentation or not?

I used that sentence a lot today.

I suppose I did expect a high expectation for the class. BUT they couldn't give their best.

A presentation should be important in delivering their research result, but most of them failed to impress me. A simple one, they didn't finish their assignment.

I plan to give their result next week, and hopefully they will know where-when-how-what kind of things they fail on.

Anyway..
