Praise be to Allah.
CDs that contain lesson plans for teachers, with different materials for teaching, are undoubtedly the result of a great deal of effort, as is clear to anyone who examines them, and therefore come under the copyright of the authors, programmers and publishers. It is not permissible for anyone to obtain them without the permission of the authors. This issue comes under the heading of “the rights of authors and inventors” (copyrights and patents), which is an established right of the author and is protected according to sharee‘ah. Therefore it is haraam to transgress against it by making copies of the CDs and trading in them. But it is permissible for the one who has purchased the original CD to lend it or give it to someone else, because he owns it.
Simply clicking on the oath button does not count as an oath, because it was not uttered out loud and it was not written down.
To sum up: it is permissible for you to give the disc to your colleague so that he can make use of it.
And Allah knows best.
