Most tips here are very good, suggesting books ("Clean Code", etc.), team huddles and showing them the way. But you seem to be implying that they could be great coders - if they wanted to. I can't help but feel like these programmers aren't very passionate about their code, and that's what you need to help them with. If they're naming variables wrong and hardcoding strings, but understand the asymptotic running times of what they're doing, I'd go on a hunch and say they're bored or unmotivated. I say this because I recognize myself in some of these behaviors - when I want to get rid of something and don't care much about the project. "What's the fastest shortcut I could take to get me out of here?".
