German德國 Table tennis 乒乓球 trainer 教練 just 只是 taught from book 從(from)書本(book)教學(taught) - word order in Chinese is different from English If you tell him that 德國乒乓球教練只是從書本教學, he probably understands what you mean. I guess your another hidden meaning is the german trainer seldom shares his/her practical experience in table tennis skill or uses active, hands-on teaching and learning activities.

I think you meant to say 德国教练照本宣科，是吗？

教书的is a none, means" teacher" in Chinese. I cannot understand clear what you mean. If you want to say somebody learn sth from book, we say "从书上学的“

教书的可以做名词 如 我就是个教书的 还有就是做形容词 比如 教书的人都有职业病
