In 1974, I wrote a program that produced whole paragraphs consisting of grammatically correct education jargon ("Jargon generator offers a reality check on language", 31 December). This "exposition" was followed by questions requiring long answers. The program randomly decided whether student responses were correct or incorrect and then provided additional comments expanding or "correcting" their replies. I was asked to remove the program when students started quoting it in their assignments.
