I love it! Another great reminder. Or, perhaps, an exemplary primer for many young teachers.
The first paragraph on page 192 lays it all out and is some of the best instruction that can ever be given to a "teacher" (though, big brothers and sisters, parents, grandparents, leaders, coaches, co-workers, etc., could all benefit from this wonderful advice!): "The learning environment might want to keep the learner confused (i.e., in a state of cognitive disequilibrium) and leave it to the learner to actively deliberate and reflect on how to restore equilibrium . . . learners need to experience cognitive disequilibrium for a sufficient amount of time before they adequately deliberate and reflect via self-regulation (Lehman, 2012)."
I've watched many "teachers" jump to answer a student's question as soon as it is put forth by the student. This does two very negative things, in my opinion.
First, the student gets "no-cost" information immediately and effortlessly. The lack of "payment" or the student's own hard searching for the answer to the question (even if it is only a Google search) discounts the value of the given answer to the student's problem. We all know how much value we put on something that is free of charge. "一分钱一分货 or Yi fen qian, yi fen huo." (Did I get that right? One of my very favorite Chinese sayings.) The student, in my experience, is less likely to value the knowledge gained (if it is even considered "knowledge" in the student's mind) and less likely to value the source of that "knowledge" - our dear teacher - if information comes that quick and easy.
Second, the student is robbed of the feelings of self-efficacy, achievement, pride, and the subsequent dopamine that comes with discovering the answer on his or her own. It is that whole "Don't tell me! I got this. Just give me a minute." feeling that one gets in mental pursuit of an tricky answer. I believe that when that light bulb goes off, and you see it on the student's face, they have cemented a concept or bit of knowledge, purely because they have come to it all on their own. And, it is a beautiful thing!
I also love the digital attractiveness of our dear AutoTutor. I assume it may be individualized a bit depending on the student user. I used to ask my Saudi boys to download the mobile app Assistant (2014) as an English tutor & oral practice buddy:

They absolutely loved it! A pretty girl with a soothing voice is a great study buddy, digital or not.
When asked whether or not teachers will be replaced by machines, Sir Arthur C. Clarke once said, "Any teacher that can be replaced by a machine should be." Ominous words in light of AutoTutor. However, we are not yet to the point of strong AI that can sense a user's emotion to the degree a teacher should be able to. But that time will come, as certain as Gordon Moore's Law will keep predicting technological advancement. We'd better make darn sure that we're able to allow "puzzlement" emotions ("confusion" just has negative connotations for me) and be able to spot it when it happens.
Cheers!
