How can i optimize the use of my convection oven?

Is there a resource i can use to learn how to bake in my convection oven? I know that it can improve the results greatly and i am just not understanding it. I know that you are supposed to bake at 25 degrees lower temp but it seems like all my baked goods seem to dry out or brown too quickly. I thought it was supposed to just bake things more evenly.
