Copy-Right

I learned so much things about copy-right and I was surprised. I learned these rules before I am a teacher, I think why don't the other teachers apply these rules in their classes. Because I witnessed these rights being broken. However, I think some rules are very strict. Internet is easy way to use pictures,music and videos despite of copy-right and these materials encourage students to participate in class.In my opinion, these materials can be used more conveniently in education.
