but also open a serious question: What is a textbook?
Just as an example why a cookbook is not a textbook? In many school
cookbook are used as a textbook. Morover they are used in some small
lecture course about cooking. What should be consider as a textbook?
Just what is normally used in American High school?
A joke book could be a text book for a writing course or a drama course
about stand-up comedy
And should the subject only be limited to normal
subject textbook are
written about?
For instance there exist a lot of book about chess (and many of them
not only dealt about chess, but are even organized in lesson). Anyway
I have never seen a textbook about chess (because chess is not taught
at school).
There have beenany number of self-teaching books about chess. One type
has you following a game, and rates you on the move that you would make
in any given position. Chess may not be a part of the standard
curriculum in American high-schools, but there are private schools and
schools in other countries which consider chess an important tool for
developping critical thinking.
