Open Source Replacement for Borland Delphi

As a student of Mathematics Department in State University of Malang, I must confront with Borland Delphi programe for the Basic Computer Programming lecture. It's not my way, because I know that Delphi is a proprietary software, and it isn't free. So, I decide to see other alternatives that Open Source World offer.
Then, I came with Lazarus. A free pascal IDE and RAD tools. Everyone that used to play with Delphi before, will feel comfortable using this software. It's truly a better replacement for Delphi.

But, I think it's still lack of Help and Documentation. And for beginner like me, it's hard to learn something from only the IDE itself. I must collect many source from other place to complete my knowledge about Object Pascal. More over, It's harder to find pascal and delphi documentations compared with Perl and Python.
