This module we talked about internet safely and may issue in the internet. One is the cyber-bullying, the other is teachers use social media communicate with students are right or wrong?The cyber bullying I think it need stop, this issue is not only in the USA but also in my country. I had some nieces they are using the internet everyday. The iPhone with they are all day. I do not think this is a god thing in their life, they are still teens, but do not have Tina. This is so terrible thing. I have a fond useful website which is talk about cyberbullying by government. I feel this website is helpful for parents and teachers to define if their students or children have cyberbullying.The second problem is about social media. I this the social media have a double side apple with students and teachers. I think the teachers need have students' social media account if the students want, but don't need to connect to them. So after this week studying I realized we need follow some suggestion from this module:

Never give out personal information online, whether in instant message profiles, chat rooms, blogs, or personal websites. Never tell friends or anyone other than your parents your password. Don't respond to mean or threatening messages. Save or print them and show them to an adult. Never open emails from someone you don't know or from someone you know to be a bully. Don't bully anyone. Don't put anything online or in an email that you wouldn't want your classmates to see. Don't send messages when you're angry. Before clicking "send," ask yourself how you would feel if you received the message. Don't join in when other people are bullied online. Show bullying messages to an adult.  Always be as polite online as you are in person.

And I highly recommend the parents and teacher pay attention their children and students did they have issues on the internet.This model also gives some cyber-bully methods include:

• Sending malicious email and text messages.

• Sending someone's personal or embarrassing information to others.

• Breaking into accounts and sending inappropriate messages as if the messages were from the account owner.

• Posting or sending images of people without their permission.

• Excluding someone from social networking groups or blocking their email or text message without cause.
