What and Why
Bullying, pornography, ethical issues, legal issues all fall into what I'm calling "e-safety." While you may be comfortable cruising the internet, not all families are equally comfortable. Not all students practice safe technology use. Depending upon the grade and content you teach, you will have differing responsibilities for teaching e-safety issues. All teachers will need to teach and enforce copyright and fair use rules. PE teachers are increasingly being asked to teach about internet safety including bullying. Music teachers as well as cheering/dance team coaches need to know what the rules are governing the use of music in public performances. All teachers need to be aware of what movies they can show. Just because you have seen it done doesn't mean it's legal.

Site for info on public domain status for music: http://www.pdinfo.com/proof.htm
Site for Australian Copyright Organization that does a very good job of describing the law as it applies to music and public performance: http://www.copyright.org.au/pdf/acc/infosheets_pdf/G059.pdf
I like these sites because it talks about the fair use of music. Physical education teachers like to have music playing in the gymnasium however, they might not be doing it legally. These websites can tell teachers how they can use the music in their classroom.

Some other websites I learned from Dr. Cramer's class about e-safety I think are important for teachers are:
