Together with the students, we created the criteria for their trailers, which we would make using iMovie. We decided that about half of the illustrations in the trailer should be their own. The trailers had to include the author's and illustrator's names, and we discussed the Fair Dealings copyright laws of Canada, which states that "short excerpts" of printed material can be reproduced for educational or review purposes. Because we wanted to upload the trailers to YouTube, we also discussed parental permission for putting their work online. Parents were asked to indicate exactly what their children could put online, including their work, their first name and their image. If permission was not granted, that child's trailer would only be viewed in class and not uploaded. If no name was to be used, the students used an alias. And if no image was to be included, we just made sure that no photos included the child's face. We really hoped that we could upload to YouTube, as we wanted to create QR codes for the trailers, as discussed below.
Lastly, once the trailers were completely finished, we uploaded to YouTube, and then used the share code to create a QR Code on goqr.me. We printed out the code and attached them to the inside cover of the books. Now, when students want to check out a book from the school or classroom library, they can use i-nigma or another QR Code Scanner app to easily view the trailers. (I wrote about using QR Codes in the classroom here.) I should mention that when we uploaded the trailers, we decided to make them unlisted. That means that if someone searches for the trailers, they can't be found. The only way someone can watch them online is if they have the link (or the QR Code).
