Don't dive multiple enemy champs by yourself. Bring backup to the fight. Don't hang around enemy champs at low health. Watch for when enemies are trying to bait you. In other words, don't get yourself killed, play carefully.
Work on last hitting a lot. You need gold to become stronger, the more the better.
Don't push your lane unless you have a good reason, (like you can take down their tower reasonably quickly) keep the waves in the middle or closer to your tower otherwise so you don't overextend yourself.
Work at being aware of what's going on in the game. Check up on the positions of enemy champs on your minimap frequently, note any you can't see. Buy wards and use them to cover spots that somebody might try to catch you by surprise from. Use wards all game long, the more of the map you have vision of, the better.
You don't have to blow all your skills just because they're off cooldown, often you are better off if you wait until the right time to use certain skills instead of spamming them. Mana costs also add up, and nothing is worse than being empty when you need to use a skill.
If you can do those 5 things, it will already make you better than probably half the players out there

I'll play with you every once in awhile on a smurf if you have skype. Maybe a couple games here and there. Try to teach you some of the mechanics of the game. I'm far from a pro, but I'll help you out as much as I can

Most important thing to do at low level is to concentrate on not feeding.
Things like improving your cs, learning when to tower dive, ward spots, item knowledge etc will all come time.
I admit to being fairly new myself, but on the subject of not dying, in general the closer you are to your tower, the safer you are. Just be careful that your opponent isn't trying to push your tower, as once it goes down, it gets more difficult to turn the game around in general.
Likewise, if you start trying to advance into enemy territory, the further in you go the better your chance of being killed just like that. One good ambush from two or three champs when you're on your own is basically death without chance for any sort of resistance. Wards in general are a nice way to keep from being killed, as they will give you early warning when an enemy approaches. Make sure to put them into bushes leading into the jungle when you start moving into lane or retreating back on your own lane.
