Using stop motion to teach, just like using music in lessons, creates lasting memories. With all of the different processes you go through to make a stop motion film, not to mention the finished animation itself, it promotes truly meaningful learning.
When I was a teacher I got my class to make stop motion animations of the water cycle, as a lot of children can find the concepts tricky to get to grips with. After a couple of weeks planning and making their films it was joyful to see how much it helped their understanding, not to mention the great teamwork and how proud they were of their creations.
