There is a lot of literature out there for Certified Flight Instructors about positive reinforcement. It sure is an important part of the teaching process. When your student is struggling, it’s often best to keep reinforcing the ultimate objective rather than pointing out the negatives. From my own experiences I can honestly say it’s not the easiest technique (pointing out all your students mistakes is just so easy to do) but the most effective.
I don’t know all too much about puppies, but it seems Julio does and the system might work almost the same way. I guess I consider myself lucky (or successful?) that I have not been swatted by a mechanic with a newspaper (yet).
On another note: It’s been 20 years since Chuck and Julio were born. What do you guys think of posting a few additional strips to celebrate?
