'Homing' is where you
would continue to keep the nose of the aircraft pointed at the beacon,
regardless of wind drift. This will result in you flying a curved approach to
the beacon as you constantly change heading towards the wind, eventually
finishing up pointing directly into wind.
'Tracking' is where you make a calculated adjustment for wind and fly a
constant course towards the beacon, with the nose of the aircraft pointing into
wind at the calculated heading.
