Narrative:

A piper PA-28 was on the downwind sequence number 4 to follow an aircraft on a 4 mile final for runway 9R. The pilot was confused and he turned base to follow an aircraft on a 2 mile final in front of a cessna 172 IFR on a 4 mile final. We issue traffic call to the PA-28 many times. We told the PA-28 to turn south to avoid conflict. Training was in process. It is my view that the developmental used all necessary tools to fix a situation that was developing. At no time I feel that I needed it to take the frequency; he saw the conflict and he fixed it. After listening to the type; we realized the read back was blocked because another pilot was calling inbound. I personally think we did fix the situation the best way possible. This is a training airport; we provide excellent service to the pilots. I think student pilots are rushed to solo flight without proper training; even if the read back was unreadable; it is the pilot's responsibility to maintain VFR and a safe operation. Language barriers are a big problem in this airport. This situation happens everyday and we need something towards fixing this unsafely events. These types of events also happen when instructors are on board and take no action to fix a problem.
