And a new one (new as in it happened to me for the first time earlier today):
Student does not appreciate that there are two distinct phases: the round-out where you transition from descent to straight+level, and the hold-off where you maintain straight+level as the aircraft slows down. Student therefore merges the two phases into one and applies a continuous pull on the controls.
(However, as well as lack of understanding, which is easilly fixed, this is also symptomatic of what HFD says about looking further away.)
