At least in my Texas history class, we weren't taught that the Alamo was a battle of strategic importance. And obviously, the Texans lost, so it didn't help us in that way. It was though an important cultural moment that became a rallying cry and unifying force (ie 'those evil Mexican bastards massacred us at the Alamo, we need revenge!'). And its hard to argue with the result the Texans got.
