Making a photostory or a movie is my favorite tool. As I described earlier here are the ways I would use it:
1. A photostory can be used in many teaching ways starting with lecture, giving examples,creating a project or assessment and finishing with comparasion and discussion of one theme based photostories products created by different students (groups)and combined as one as a conclusion made of the best pieces.
I would personally have my students to create a photostory project given a particular physics assignment. Let's say solving one complicated multiple-steps physics problem by diffenet ways, presenting the ways by the groups ,discussing them and picking out the best one.
2.Given technology and mastering the tools would make a total difference in my classroom which would make learning environment more fun and give the chance to my students to explore the topic from different resourses,makng it more understandable and more sense!
3. I am not sure if I understand of what is being asked. The program took me MUCH MORE time than I expected probably because all these tools were new for me.
