There are three basic parts of a landing, the approach, the flare, and the touchdown.
1. The approach should be stable, at a constant recommended airspeed and on glideslope (the correct and wrong perspectives should all have been demonstrated to you by your instructor). A good approach leads to a good landing. Remember that power controls height (ie low, add power, raise nose to maintain airspeed) and pitch controls speed (ie too slow, lower nose to get required airspeed).
2. As you get closer to your aiming point (most probably the numbers), you start to round out (the flare). To avoid ballooning, your airspeed should be at the recommended speed. Close the throttle (or as instructed) and look at the end of the runway. This achieves two things. Firstly you can keep straight using your feet by looking ahead. Secondly, by looking ahead, you don't get a ground rush and try to avoid the ground by pulling up briskly (a common fault). Ground rush and excess speed are the two major contributors to ballooning, or getting too slow and bouncing.
3. The touchdown or landing is done from the flare. Simply keep looking straight ahead, close the throttle (if not already) and try to hold the aeroplane a few feet off the runway (estimate this by feel, don't look or you'll defeat the purpose of looking straight ahead). This should allow you to land in a slightly nose-high attitude and a smooth touch-down.
Landing can be difficult in conditions out of your control (ie wind), but good basic understanding and practice will give a good platform from which to improve.
All the best, hope this wasn't too long winded for you and hope it helps.
