aristotle on the concept of teaching

Hi all. I read in Nel Noddings _Philosophy of Education_ that Aristotle analyses the concept 'teaching' by way of someting akin to a task/achievement-distinction (p.74 in my Norwegian edition, chapter 3, 2). Further she claim that Aristotle argues that the task (teaching) and the achievement (learning) are located in different spaces/persons, viz. the teacher and the student/learner. Anyone knows where Aristotle makes this argument? Assessment of Noddings claim? Thank you in advance and best regards.
