Dr. Smith teaches economics at the local senior high school. During his class, he copies examples from the book onto the blackboard and works through them with the class. Does this violate the amended Copyright Act?

Yes, because he is using parts of the book without permission

No, because educational purposes was always part of the fair dealing exception

No, because the fair dealing exception has been expanded to include classroom uses

Maybe, but only if the author formally registered a copyright for the textbook

Yes, because the author of the book intended to protect his work
