Ok - so another one of my favorite peeps, @Angela Mahoney and I did this crazy session at #df15 and I can tell you that, because I just re-watched it. If you want to learn ways to understand these coding concepts and have fun doing it, then check out the video (and let me know what you think). 

In our session we take you through the seven building blocks of force.com coding, all based around a tacky tourist theme. Classes, Objects, Variables, Methods, SOQL, DML and Triggers. I know it sounds nuts, but hey, consider the source.
