There are so many uses for PhotoStory!! The teacher can use it for every topic! (If they have the time to create them!) The story can be used over again for homework assignments, discussion starters, review before tests etc. With that being said, I much prefer Windows Movie Maker. I found that Windows Movie Maker had the choices listed in bars to the left that were much easier to scroll through to see what your options were. I also feel that it will be easier for my third graders to use.
