I think that student engagement and overall experience are paramount to maximizing the learning environment. If the student is generally disconnected from the institution, staff or content then it is not likely they will apply themselves or demonstrate commitment. Education is a personal endeavor that requires constant application of discipline and it seems most students require an external motivator to remain successful. Having quality instructors, solid peers and supportive family are critical. So many external pressures and factors can influence student retention and a good instructor will work to create an education environment that is supportive and relevant to each student. This can be challenging in classes where the student to teacher ratio is tilted.
