Should teachers start a lesson by listing the Learning Objectives?

[S.R Thomas]

I was teaching my grade seven Visual Arts class and incorporated all of my learning activities. This was done using the questions I wrote using the guidance of Blooms Taxonomy, my question is really simple, should I informed the class before all the objectives that will be covered in the lesson? I usually don't, sometimes I project the information, sometimes I write them on the whiteboard. Mostly I just let them flow throughout the Learning process.
