Aperture is not the only factor to consider when we're talking DOF. It also is greatly effected by your focus point. Remember, 1/3 in front of focus, 2/3 behind. Logically if your focus is ten feet from you, zone of sharpness will be around 7 ft >around 20ft.

You might be shooting subjects where the depth of field isn't that noticeable. For example, if you'll only start to see a difference at 12 feet, and you're only shooting something where the background is at 7 feet, you're not going to notice the difference. Have you been shooting the same subject with the different f-stops to see the results?

DOF is also influenced by the lens you're using. If its a wide angle, say 12mm (equivalent to a 20mm +/- on a 35mm film camera, and your subject is 3' away, you won't see much change from f2.8 to f5.6.
Your sensor size also plays a role - the smaller it is the more DOF.
