What technology skills should be acquired by students at the grade level that you teach?
What are the essential elements that should be addressed by an effective classroom technology policy guide for the grade level that you teach?
What Internet safety issues should students and parents, at your grade level, be informed of?
Review and respond to the blogs of at least two other people in our class.

I teach adult education and mainly courses that involve students being able to use the computer proficiently. Students who sign up for my courses need to have experience using computers and have to understand how to manage their work on the computer.
The main elements that need to be addressed in a classroom policy guide with my students have to do with expectations when students are using the computers. Since our students are older and some are more experienced we have to make policy in regards to changing settings on the computers they use. We have many classes that use the computer and if students are changing the settings then when the next students come into use the computers they are not working the same as other computers. We have addressed this issue with students but we need to be make sure that they understand the need for the computers to all stay on the same settings. No matter what we do to try and prevent students from changing settings they somehow find a way to do it.
I think that the Internet safety issues that my students need to be aware of is that information that you have on the Internet is viewable to everyone and you need to be mindful of that when you use the Internet. Since my students are adults and many are using the Internet for job searching I warn them to be aware of scams. If anyone asks them to send money in order to secure a job I tell them that this most likely is fraud.
