The first pilot session of the Homeschooling 2.0 project has been completed today.

The educational possibilities are truly exciting: group instruction, observational learning, and meaningful interactions among participating children, all of whom are on the Autism spectrum.

Together with a group of parents who have become skilled ABA Technicians, we addressed and solved the first challenges and began establishing **group instructional control** through targeted, live, synchronised activities involving all the children.

I ended the session with immense enthusiasm and look forward to sharing further developments!

1. Today’s lesson was especially interesting. The topics covered, which are relevant to many of us, prompted deep reflection on how educational this course is and how much more aware it has made me of how we function. Michael is always at the top of his game: composed, calm, precise, extremely clear in his explanations, and professional in addressing every topic.

2. Today’s exercise with an adult was really, really powerful for me. Michael, you are truly one of a kind in the way you approach, solve, work through, and explain things to us. Thank you, Michael.

3. Honestly, I’m struggling. I can no longer find any compliments for the instructor that I haven’t already given. Simply one of a kind.

4. What an amazing lesson!

5. We are now nearing the end of the course, but Michael’s lessons are still as interesting and rich as the first ones. Watching our classmate’s exercise today was fantastic. Thank you, Michael, because every one of your lessons is a life lesson. 💯❣️

6. Since I do not intend to work as an ABA technician, I had somewhat underestimated the lesson on ethics, even though it is important, because I had already read about it. The live exercise with an adult was extraordinary!!! What a precious gift you gave us, Michael! A whole new world opened up for me! It may have been the most meaningful exercise for me of all those we have done so far. Despite the organizational complexity caused by the lessons being rescheduled during this summer period, I am sure I will miss our Wednesdays and your scoldings.

7. Today’s exercise was wonderful! It showed us how adult problems can be addressed and how broad ABA is.

8. Our Michael! What can I say? Today I did the live exercise with you and opened up so much in front of a virtual audience, but an audience nonetheless. I liked how you managed to guide me and help me analyze my eating behaviors. The possible intervention you proposed was wonderful. I believe I was very useful to the class, and I am convinced it will be useful to me as well. I will miss your lessons, your input, your seriousness, and your ethics so much... What else can I say? Nothing, or I risk sounding overly flattering! See you next Wednesday.

9. Fantastic lesson! Thank you from the bottom of my heart, and many thanks also to the participant in the practical exercise involving an adult.

10. The best part of this fantastic course is certainly the professor, with his expertise and passion, but also the practical exercises, which make every lesson engaging, concrete, and truly educational. Congratulations to everyone!

11. The live adult exercise was exceptional, with extremely rich analysis, assessments, and guidance that thoroughly examined and laid bare all the variables and dynamics driving our behavior. Michael Nicolosi was outstanding.

12. Wonderful lesson. Every lesson is nourishment for the mind: you do not simply listen; you truly grow. Thank you, Professor. ❤️

13. I continue to think that taking a course with Michael Nicolosi is truly a great privilege! Today we covered a topic that does not affect just one person but is shared by many people, and once again you enlightened us with all your knowledge, the result of your study and experience! I am increasingly fascinated by the clarity and precision with which you address every issue we bring up. Regarding today’s lesson, I think no one else in the field will ever talk to us about ETHICS! Thank you! 🤩

14. An extremely interesting lesson. Planning an intervention for a problem many of us may have was incredibly useful. A lesson on ethics that might sound boring from the title was instead made interesting by Michael’s many examples.

15. Enlightening as always. Thank you.

16. Today’s exercise was fantastic. Thanks to Michael and my classmate. 🥰

17. The lesson was rich and interesting as always. Michael Nicolosi, you are the absolute best!!!

18. A truly interesting lesson. We apply behavior analysis to problems that involve all of us to some extent. Michael is always our super professor. ❤️

1. A great, very educational lesson.

2. Thank you for teaching us useful things every time so that we can learn how behavior analysis works. Maybe I do not always apply them correctly, but I keep trying to use them with my child so that I can gradually learn how to put them into practice. And I know I can ask you about anything. Thank you, Professor.

3. A lesson rich in content. Michael’s explanations are always thorough and comprehensive. Top-notch course!

4. I hate suck-ups who, on top of that, do not understand a damn thing.

5. You are one of a kind, Michael. Thank you for guiding us.

6. Today, too, we gained so much clarity about situations related to autism that had been presented to us as impossible to overcome... What can I say! Study, study, and just keep studying—a lot... THANK YOU, PROFESSOR!

7. A course in behavior analysis is definitely something all parents should take. So many mistakes are made without realizing it. Meeting you was enlightening. Thank you!

Anonymous participants’ comments

1. Michael, today you once again demonstrated through science how much our unicorns can work against us and how necessary it is to intervene using evidence, even though it may be complicated at first, and how effective it is... THANK YOU... ❤️

2. There is only one word to say: THANK YOU FOR YOUR LESSONS, THANK YOU FOR YOUR EXPLANATIONS, THANK YOU FOR YOUR STUDIES, WHICH IMPROVE OUR CHILDREN’S LIVES.

3. Hi, Professor!! Another great lesson today; I learned so many things, both practical and theoretical!! I could listen to you forever!! Thank you so much ❤️

4. A crucial point in today’s lesson was extinction. I would suggest, if possible, spending more time on or going into greater depth on this topic and on problem behaviors. Otherwise, I would like you to tell us which advanced courses to take to address problem behaviors, academic skills, and language in greater detail. I am very confused about which advanced courses I could take after this one in relation to the areas that interest me most. Thank you, and congratulations as always.

5. Michael, you’re fantastic!

6. I love watching the practical videos of the children you have helped.

7. An absolutely fantastic lesson. I especially appreciated the attention devoted to the prerequisites needed to apply the extinction procedure correctly and to the importance of using it ethically. The videos shown were extremely helpful in making the procedure easier to understand, while also showing the mistakes to avoid. It was a useful, concrete lesson that can easily be applied in practice.

8. Today’s lesson was truly wonderful and interesting, with practical tools to use right away. It seems that at times you get frustrated when people ask questions that may seem obvious to you, or perhaps because we still do not express ourselves correctly without unicorns... We are right in the middle of the course, so give us time and we will surprise you.

9. I will never stop thanking you. Another thank-you for your constant, attentive availability outside course hours, because we keep the lesson going since you always answer everyone’s questions. Thank you so much.

10. Michael, you are a beacon as well as a great professional. I hope I can also take part in future courses so I can continue learning more and more about behavior analysis and help my son reach goals that, until recently, I had been told were impossible. Thank you for your work and your passion ❤️‍🔥

11. A beautiful lesson. Watching the videos is a huge reinforcer; seeing everything we study become reality is important. Meeting you was enlightening.

12. I found today’s lesson well balanced between lectures and discussion.

13. Excellent lesson. The idea of having the discussion at the end was great; the explanation was intense.

14. Every lesson is a ray of light for me! Another very practical lesson today. Thank you for correcting me when I say something incorrectly; it helps me so much in learning how my child functions. Listening to you in every lesson gives me an incredible boost. At least once in my life, I have been fortunate enough to choose the right path for my son. I also wanted to ask whether, in the next lesson, we could see some cases in which the diagnosis was removed, if possible. Thank you, thank you.

15. This was a very good lesson. It was not interrupted by a thousand questions, so the instructor was able to cover all the content without interruption, with his usual clarity of presentation and memorable examples from everyday life that help us remember what we learned.

Anonymous participants’ comments

1. Every one of your lessons is always extraordinary.

2. The lesson was packed with instructive content on interventions to change problem behavior and, once again, on how to focus on behavior in practical terms and describe it concretely without using expressions such as “he wants,” “he didn’t understand,” or “he intends to,” so that it can be changed.

3. A rich and comprehensive lesson on problem behavior. Michael is fantastic at explaining how to reach the solution. Thank you!!!

4. A very interesting lesson full of insights, especially the section on self-monitoring and intervention procedures for stereotypy.

5. An extremely important lesson on a very delicate topic: problem behavior. We learned that even the most difficult behaviors can be treated with the right training and, above all, with the guidance of an expert behavior analyst. Sometimes a few unicorns still pop up in our verbal behavior because, unfortunately, our learning history is long, very long, but we are putting all our effort into eliminating them for good. Michael, endless thanks for the patience you put into your explanations, because every time we fall into the error—the unicorn—you immediately put us back on the right track. This is what makes a teacher a true teacher: even if we make mistakes a thousand times, your MO always stays high. So much admiration for you!!

6. There are only two lessons left, and I will miss Michael’s Wednesday showers of wisdom. There are no words to describe the expertise he offers. I know I keep repeating myself, but every lesson surpasses the previous one. Now, when my older daughter sees her little brother struggling, she tells me, “Mom, ask Michael. He will definitely know what to do!” :)

7. Another wonderful lesson today, well balanced between theory and video analysis, which definitely left a mark on us! The results achieved by the children were incredible and, above all, encouraging for those of us who have just begun this new journey, thanks solely to the teachings of our great Professor Michael Nicolosi 🤗

8. Today’s lesson was truly outstanding and very interesting, Michael. Thank you for everything you share and for opening our eyes!

9. A few months ago, my son engaged in stereotyped behavior involving water, and today I can confirm that he now does it very rarely. It was truly interesting to understand these mechanisms better.

10. Michael explains complex terms simply. He manages to engage you from the beginning to the end of the lesson. What more could you ask of a teacher? One of a kind.

11. We’re nearing the end, and I already know I’ll miss this class and our regular Wednesday appointment, which has accompanied us since October. I’ll miss Michael’s spectacular lessons and his scoldings. Today, too, the testimonials about the progress achieved by the clients Michael works with were incredibly valuable, along with a brief dive into advanced topics as an extra bonus. Thank you!!!

12. Another super-intense and fantastic lesson today. So many interesting concepts and an always stimulating discussion. Today I was there and not there because my son was home with me, so I’m sorry I couldn’t participate fully, but I really loved what I was able to follow, as usual. Michael never disappoints.

13. Time best spent, as always... Thank you, Professor ♡

14. Super lesson... Michael Nicolosi, what will we do without you? 😢😞

15. I found today’s topics very interesting, as always, and today’s explanation gave me useful ideas to study and apply at work. Michael’s passion and the simplicity with which he addresses such complex and difficult topics are fascinating and captivating... Thank you for the patience you always show.

1. A very useful exercise. Everything was necessary. There were no human rights violations, although it can be extremely challenging for a parent because, for developmental reasons, when faced with certain statements from a child, the parent must follow behavioral rules that feel “unnatural” in order to stand firm for a greater long-term benefit. It is tough.

2. An exceptional exercise, with excellent clarification during the discussion. It is also not so different from what they do at school every day, except that at school we are not given the opportunity to manage situations this way. In this case, they would have considered us incapable of calming the child.

3. Excellent!

4. Great exercise!

5. The exercise was grueling but extremely thorough. It taught me many things, and I saw how to intervene practically when my son says no. He does not have a diagnosis, but he is very persistent. Thank you.

6. Today’s exercise and lesson were the most practical yet and clearly demonstrated the control our children have over us. Holding firm makes the difference and allows us to turn the situation around. Thank you, Professor Michael.

7. A wonderful lesson.

1. Thank you for teaching me to look at human beings from a new perspective. Everything makes sense when you observe. Little by little, motivating operations and discriminative stimuli are also finding their place. Thank you!

2. Thank you for the wonderful lesson and the countless practical examples. I found the topic particularly interesting. Every lesson gives us practical tools that we can use in our daily lives.

3. Hi Michael, this was an extremely intense lesson! The exercise allowed us to get into the field and put ourselves to the test. What a workout! Thank you so much for everything you are teaching us. The theoretical section was a little complex today, but your diagram made everything very clear. Thank you, and see you tomorrow!

4. A great, content-rich, and motivating lesson. Little by little, I am finally starting to put the pieces together and, above all, bring order to the chaos I have experienced over the past year and a half because I did not understand how to interpret my son’s behavior and other behaviors as well.

5. Your content is becoming increasingly clear, concrete, and truly applicable to everyday life. Thank you, Michael. With your contribution, my work—and perhaps my life as well—will become more productive and full of new opportunities.

6. The lesson covered some content that was a little difficult to absorb, but thanks to you, Michael, we will manage. The final visual map you created to help us understand the distinction between motivating operations and discriminative stimuli was very useful. Could you create similar maps to explain other concepts? They help me a great deal. Thank you again.

7. I could not wait to reach this point so that I could better understand the distinction between discriminative stimuli and motivating operations. I tend to get confused, but today the distinction became very clear. I will try to come up with some examples. Thank you very much for your professionalism and clarity.
