creating good objectives

This is an important topic to me.Objectives are the base of teaching i knew that i have to begin to do something thinking what do you want that students reach at the end of a class or course.But i wrote my objective so general. So, now i know that objectives should be specific i never notice that my objectives start sometime for the harder part to the easier.My coordinator checked it out and he says that the objectives are correct but now i can improve my classes objectives and the activities. It is wonderful and interesting how teachers can get many things with a clear objective.
