6.3 Internet Safety
Because of the amount of online content being generated and the safety issues surrounding students and teachers on line, many lead teacher workshops and Principals meetings were held in 2009 to discuss these issues.

School policies, systems and procedures were updated and teachers, parents and students were made aware of these issues. All lead teachers ensured that each blog was identified as a school site for specific school content.

“With the increased understanding of their voices being heard around the world and that we and others, as an audience, have a choice of what is viewed or read, students are becoming much more aware of what it is to be online –the safety issues and the need to make effective posts”

During interviews with students it was evident that many of the older students were very aware of the need for appropriate posts on a school blog and also the need for teacher censorship. Some were also aware of plagiarism and the responsibility of ownership of one’s work.

In 2010 one teacher commented that after an unfortunate incident where a student was able to get into another child’s files, how important it was to have individual logins to protect student work. The incident was dealt with quickly and highlighted the importance of keeping passwords safe.
