No, you have to keep pedaling. "Changing gears" means that the chain will be moved from one cog to another. On your rear hub, you'll have a spring loaded mechanism with two small jockey wheels called a derailleur. See how the chain is threaded around the cogs on the hub and through the jockey wheels? The lever in your picture above is attached to a cable, the other end of which is attacehd to the derailleur. When you push or pull the lever in the picture, you'll move the derailleur in or out, thus "derailling" the chain from one cog to another.
