I’ve been working with a small group of people on a coding project for fun. It’s an organized and fairly cohesive group. The people I work with all have various skill sets related to programming, but some of them use older or outright wrong methods, such as excessive global variables, poor naming conventions, and other things. While things work, the implementation is poor. What’s a good way to politely ask or introduce them to use better methodology, without it coming across as questioning (or insulting) their experience and/or education?

Introduce questions to make them realise that what they are doing is wrong. For example, ask these sort of questions:
I think the ideal way of going about this is subtly asking them why they code a certain way. You may find that they believe that there are benefits to other methods. Unless I knew the reason for their coding style was due to misinformation I would never judge my way as better without good reason. The best way to go about this is to just ask them why they chose that way; be sure to sound interested in their reasoning, because that is what you need to attack, not their ability.
A coding standard will definitely help, but if it were the answer to every software project then we’d all be sipping cocktails on our private islands in paradise. In reality, we’re all prone to problems and software projects still have a low success rate. I think the problem would mostly stem from individual ability rather than a problem with convention, which is why I’d suggest working through the problems as a group when a problem rears its ugly head.
Most importantly, do NOT immediately assume that your way is better. In reality, it probably is, but we’re dealing with another person’s opinion and to them there is only one solution. Never say that your way is the better way of doing it unless you want them to see you as a smug loser.
