Yes as I wrote above and as elaborated on by TLIK. In short, there definitely was place for this in the past but today’s generation needs to be reached with love. Now this does not mean no discipline. The Rebbe worked hand in hand with hanhola and bochurim had to listen to the rules. However they werent enforced with hitting as the Rebbe held it isn’t effective long term in discipline today.
you might be interested to know that regarding chinuch the Rebbe had a pretty revolutionary approach that we should get the kids to learn for the sake of learning, not for prizes etc. There is a beautiful article by Rabbi Levi Goldstein on how he implemented this with a first grade class. I have implemented this myself in several situations. But I guess this is a sub topic so I’ll only elaborate if you’d like.
