I like this description! And I think it's important to consider that some types of thinking and learning are enhanced by walking more than others might be.
(I'm sure you have considered what I'm going to say. I'm not trying to tell you anything - just pondering here.)
Learning while multi-tasking is complicated. I have only my personal experience of this subject, but have found, for example, that I cannot do language lessons while driving. It would not be safe.
I sometimes do interactive Spanish drills while walking. They are exactly at the right level for me, with enough challenge but not too much. I find that I can do only about 30 minutes of this, before my interest and focus drop. Maybe I can do another session after another hour or so if I am on a long walk. I can do perhaps an hour at a time when my participation is only passive (listening to a lecture). Even so, when a difficult or complex concept is being addressed, I find that my w alking pace slows significantly while I concentrate on the audio. If the subject is boring or too complicated, the distractions of the walk are too great to learn much.
On the other hand, I can walk and think my own creative thoughts (well, they seem creative to me
) for hours.
I am guessing that remote-and-walking learning would be quite complex, and would depend on the subject, and the person, and the walking environment.
I am curious about this, as I'm not sure of my own experience. Is listening to a remote lecture retained in the same way as listening to a companion's speech or a bird call?
