When I started teaching twenty years ago, I used a piece of white chalk and a felt eraser on a blackboard.  Now when someone uses the term blackboard, they automatically think of the computer postings for assignments!  Technology has changed the classroom for the better.  There is a program in the Merrick school district called READ 180, which is geared to improve remedial reading students performance.  The students wear headphones and have microphones that they use to listen to a story and answer questions.  Studies have shown student progress to be amazing with this new program.  I have now replaced my old blackboard with a new smart board that does not leave a white chalk residue on all of my clothing.  Thank you technology.
