A student should be told what they need to work on if they fail although some people might say that's spoon feeding.
How so? Why would an instructor telling the student what they needed to work on ever be considered 'spoon feeding'? How would a student know what to work on if the instructor didn't tell them? Are students supposed to have crystal balls? "Well you failed your test but I'm not going to tell you why, you have to guess!" No, don't think so.
