From my experience in EU school, a class is given a book (often fiction) to read and everyone should have read it for a specific date and everyone got a test about that book. So we are "forced" to finish the book as the test is usually including question to be sure that the student actually read the book. So by doing so, the school indirectly told the student that not finishing a book is not appropriate. I think (IMHO) this is just an effect of the evaluation process but not really a good effect to improve reading or thinking about your own reading process.
