And get very annoyed at some ATCO who thinks he knows better!
Clearly what you say is going to be right in some situations ... but there are other ATCOs who can manage rather better, for example suggesting "extend downwind" to some students and "right hand orbit" to others and "go around from base leg" to others and "can you reposition for the (parallel to the main) grass runway" to yet others depending on the ability of the student, perhaps in consultation with the student's instructor if s/he's hanging around the tower. Seems like horses for courses to me.
