Microevolution is usually the term for short term evolution, which is proven, and macroevolution is the long term use, which is not.
Microevolution- the change of one trait
Macroevolution- the change of enough traits where two once the same species can not mate and produce healthy children with eachother.
I agree that micro and macro evolution are essentially the same thing but the definitions are there to describe the time involved so it is easier to grasp as a concept since you can not make a new species when a change of one trait occurs.
