I use the idea of the five principles of proper shading to explain how form differs from shape.
Whether you are using pencil, pastel, charcoal etc. the idea is the same. As for hatching and smudging or pressure sensitivity, these are tools for making a gradation of values and should be experimented with in order to promote the best procedure for all students.

Subject: [teacherartexchange] Shaded Still-lifes
Hello All....Does anyone have any tips on how I should explain how to use
charcoal for shading and adding value to a still life?
I have been struggling a little..we are will be working on a value scale in
pencil where they practice all of the 4 techniques of shading (stippling,
blending, cross-hatching, and hatching) it has been going pretty well. But then
when they go and apply it to their objects they all get confused including
myself on what I really am asking them to do?
