Almost 650 schools across Northern Ireland are to explore the impact of cyber bullying this week.
It is part of this year's anti-bullying week which begins on Monday.
According to Department of Education research in Northern Ireland, 15.5% of Year 6 pupils and 17% of Year 9 pupils surveyed have experienced cyber bullying in recent months.
Three-quarters of teachers in post-primary schools surveyed said cyber bullying was more prevalent.
Lee Kane, regional anti-bullying co-ordinator, said anti-bullying week provided a channel for teachers and parents to challenge all bullying methods:
"We are overwhelmed by the interest from both schools and parents in this year's anti-bullying week," he said.
"It is a clear indication of the concerns that exist in relation to cyber bullying.
"Anti-bullying week is a great opportunity to reinforce key anti-bullying messages for all of those involved in schools - pupils, teachers, support staff and parents."
Cyber bullying can be exhibited through the use of mobile phones, online gaming, email and social networking.
Anti-bullying week will run until Friday 18 November.
