Answer 2

Evaluation of what?
You need different techniques for different things. I assume that because you have placed your question in teaching then you mean teacher or lesson evaluation in which case you need to look at your lesson objective and decide how effective the lesson was at reaching those objectives. Simple to do but not easy to be really objective about it,you need to look at yourself and ask did I do it in the best way possible or is there something I could do better
