Usually this problem stems from inaccuracies in oven temperatures. Gas ovens in particular are notorious for cooking at temperatures slightly higher or lower than the actual temperature setting, or for having hot spots. To combat this problem in my own gas oven, I lay a very flat, single layer of aluminum foil in the bottom of the oven (be sure that the foil does not cover any vent holes). I also place a Pizza stone on the rack just below the rack where I actually do my baking. Both the foil and the stone help the oven to bake more consistently, but tends to cause the the oven to run a little hotter than without them.
The problem could also be the type of cookie sheet you use. Dark, non-stick sheets are very popular because of easy cleanup, but they tend to overheat while being used at temperatures designed for standard cookie sheets. You may need to adjust the baking temperature of your particular recipe to allow for the temperature difference.
Regardless of the type of cookie sheet you use, I highly recommend parchment paper for all cookie baking and personally won't bake cookies without it. While it will not prevent the cookies from burning, it will improve your ability to easily remove cookies even from standard stainless steel or aluminum pans. It does prevent any unnecesssary cleanup or damage to your sheets that may result from burnt cookies. This is always a good thing.
Usually when I try a new cookie recipe, I will bake only one sheet of twelve at the time and temperature the recipe suggests as a test run. That way I can get a feel for how my oven will bake that particular recipe and can then make adjustments for the next sheet. Generally, if the cookies burn on the edges, but don't bake through, I will reduce the baking temperature by 25 degrees and bake about 3 - 7 minutes longer. Just keep an eye on them and remove once the tops of the cookies are no longer glossy.
The edge of a cake if baked properly does not have burnt edges, it has carmelized edges caused by the contact with the high temperature of the cake pans.
You can tell when chocolate chip cookies are done baking by looking for golden brown edges and a slightly set center. The cookies should be firm around the edges but still slightly soft in the middle.
when you put cookies in the oven on a baking pan, the heat begins at the edge of the pan and works its way to the middle. By the time the heat is transported to the middle the edges of the cookies are really already done. So really you have to take the cookies out when you see the edges brown, even though it may not look or feel like its done, when you give it time to cool off the cookies will be soft and warm in the inside.
You can tell if cookies are done baking by checking if the edges are slightly golden brown and the center is set.

You can tell if sugar cookies are done baking by checking if the edges are slightly golden brown and the center is set.
Crisp cookies are baked to a crisp, meaning they have crispy edges and bottoms, rather than removing them from the oven while they are soft and chewy.
Hydrangea leaves may look burnt due to exposure to excessive sunlight, heat stress, or dehydration. This can cause the edges of the leaves to turn brown and appear scorched.
Peace lily leaves may turn brown and burnt at the edges due to overexposure to direct sunlight, underwatering, or buildup of minerals in the soil. Adjusting the plant's light exposure, watering schedule, and using distilled water can help prevent further damage.
To determine if cookies are done baking, look for the edges to be golden brown and the center to be slightly soft. You can also gently touch the top of a cookie to see if it springs back slightly.
Because heat spreads from the outter edges of the pan and then into the middle so there you go!
