My gym professor in high school told us that after a hard running session, your pulse calms better if you walk for a bit after running, rather than stopping completely for a rest. Is there any truth to this?

Sorry if my question is poorly worded, English isn't my first language.

While you are running, the contracting muscles in your legs help the heart circulate blood through your body. Once you stop, that assistance is no longer available. That makes the blood pressure drop as blood begins to pool in the legs and feet.  That's why some people get dizzy after an abrupt stop. Unless you keep moving to help the heart circulate the blood, blood pressure may get so low you can actually pass out.  Although there doesn't seem to be any medical evidence that a cool-down walk will help your heart rate recover faster, it's still a good idea to do so to keep from passing out.
