Hi - Yes - we use classic notebook for teaching a lot. The idea in some ways is specifically to not give a first-time user a view that looks like and IDE but a view that looks like a written page - so that the familiarity and lack of options will focus them on some simple learning outcomes. In some ways our view is about giving novice users exposure to datascience in the least intimidating way - not even mentioning much background just dropping them into a notebook and have them clicking and learning one command at a time.
