One of the mistakes that many make is the belief that the Calvinism/Arminianism debate is about free will vs determinism. In reality, the two positions are soteriologies, and the debate is really about the process of salvation.
That said, the reason for that mistake is that the issues of free will and determinism constitute and essential different between those two soteriologies. Therefore, understanding the nature of the will and its relationship with divine sovereignty is a necessary component of the discussion. SEA has many articles about the issue. Here is a brief set:
