This is not right. Your intention is to make him admit his mistake, but in front of many people, the child feels that you have hurt his self-esteem. Now the child's self-esteem is still very strong, which may make the child rebellious. It will be a bit difficult to educate him in the future. You can find him privately, tell him what he did wrong, how to correct it, teach him patiently, and then praise him, saying that he is really a sensible boy.
