Most students and parents do not look at the copyright dates of textbooks being used. The textbooks are accepted as a tool that is not to be questioned.
It is important to note that by the time textbooks are published and receive a copyright date the information can be as old as three years. In certain subjects, the age of the information doesn’t matter. What does matter is including current material for students to learn. That is why teachers are constantly supplementing textbook information with hand-outs. Teachers may tell their students that they are not using the textbook because of the age of the information published in it.
Schools have a difficult time keeping up with the advancements of new publications of textbooks because of the cost. Most textbook prices are quite high. Many textbooks cost over $100.00 if they are purchased new.
