Copyright in the Classroom

I had not known that copyright was such an issue in the classroom prior to this class. I had always used images in my powerpoints and projects not even considering whether or not they were copyrighted. I always gave credit to the source but was never cognizant that my actions could be deemed illegal. Now as a student and future teacher I know that I have to check the copyright of images in order to use them in a lesson. I always knew that written information needs to be cited otherwise it is plagarism but I never truly considered that an image should be held in the same regard. Copyright is extremely important to bring into the classroom so students know that they need to give credit where credit is due.
