I am currently teaching my students how to use movie maker. I showed them various videos I found on Google video on movie production and editing. The following link will demonstrate how to edit clips in order to create a publication. 
Under google video there are other movie basic resources that a teacher can use in the area of video productions to assist in teaching the lesson. I found Google video very helpful. My friends at AICT, from work, recommended Video Production-shotlists and Storyboards and Kids in Action-the rule of thirds by Nortel LearniT. Also, through my search I found other videos created from Nortel that you can view.
