You can't fool the students
I taught six grade 11 classes with an average of 45 students per class. That's 270 students and a total of 1,620 pages copied into their notebooks. I asked my students (the ones who understood my questions and were able to answer me) if (a) they honestly thought that their teacher would sit down and read 1,620 pages of hand-copied notes to make sure they had been copied correctly and (b) if they thought they had learnt anything from this exercise at all.
They were honest enough to tell me that they did not even read what they were copying, merely transcribing letters and words and that they hated the exercise and had no respect for their teacher. The teacher had copied the text from the internet, printed it off and given the resultant 6 pages to each of her students.
