I have a student who posts his ideas innocently, and is ridiculed by someone posting rude comments. They are Cyber Bullies. Recently in the news, cyber bullies have been pushing around teenagers and little kids who discover the fun in posting their opinions on the internet. The internet can be a powerful resource, a fun tool used in schools for research and learning.
One of the strategies teachers can employ to teach students to protect themselves against cyber bullies, is how to read with a critical eye. They should try to see what the motives could be for someone who is rude, and mean, and posts hurtful things. Everyone has to deal with these kind of people in the "real" world as well. Helping students to develop a critical eye and skills at inferring, are valuable tools that are needed in every job.
