Narrative:

I was flying the visual approach in a distracting sunset while trying to keep visual spacing from the heavy aircraft we were following to the field. As we configured and slowed to flaps 15; we got a stick shaker alert. As I increased thrust; the shaker immediately ceased; but the captain stated the flaps never tracked from the up position to match the flap lever. I immediately executed a go-around and the captain coordinated for straight ahead climbing vectors to further access the situation. After checking circuit breakers and reviewing the QRH; I informed the captain that a check airman was riding on duty in the back and suggested he come forward as he might have more insight into what caused this problem. We then informed the flight attendants of our issue and asked them to have the check airman enter the flight deck and take the jumpseat. Together the three of us discussed the situation and decided to run the alternate flap extension checklist. This attempt was unsuccessful as the leading edge flaps extended; but the trailing edge flaps only moved a few degrees. We then decided to declare an emergency as it became evident we would be flying a flaps up approach and landing. We informed the flight attendants of the emergency; and we expected a safe landing and taxi back to the gate. I ran the QRH checklist and spoke to the passengers explaining the situation. The captain flew the approach and landing to a full stop. Upon landing; we terminated further fire truck assistance after we verified brake energy limits. Maintenance met us at the gate and informed us the airplane was grounded after they too could not get the flaps extended. We coordinated with dispatch and scheduling; informed them of our situation; and coordinated our flight home.

Title: B737-300 flight crew experiences a stick shaker during approach which alerts them to the fact that the trailing edge flaps have not moved to the selected position of 15 degrees. A go around is initiated and an emergency is declared when it is determined that the trailing edge flaps cannot be moved by the alternate flap switches. A landing with full leading edge flaps and zero trailing edge flaps ensues.
