because means "weil" in German and it is used pretty much like because in the English language. You put it before... for instance if you would say... I learn alone BECAUSE I learn better, would be in german... ich lerne WEIL ich alleine bin, dann kann ich besser lernen.
I hope this helped you a little, sometimes it's hard to put it exactly from English into German. It's a tough language but you can do it, I know...
