Thank you for reaching out to us. As you know, online education has not been quite effective for students, especially young children. At this age, a child is prone to dislike studying and just wish to have fun.
Spitting on the teacher is quite a behaviour, and the child must be confronted about the same. However, being physical with the child is not the solution. Slapping is extreme and might be a mode of punishment, but it is not a desired one. Being physical with the child may make her angry and not necessarily bring change. For change to occur, the child must be made to understand the difference between good and bad behaviour.
In your case, you can first apologise to the tuition teacher and ask her to not be physical with the child, and how that makes you uncomfortable. Despite you communicating your needs, if the pattern continues, you can choose the appropriate action to be taken.
Healthy Ways of Communicating to your child about an unacceptable behaviour:
1. Time-Out
Tell your child that the following behaviour is unacceptable and give a warning for the first time. When it happens again, give a timeout, meaning, choose a spot (a chair or a corner), and make them sit there with no toys or anything for them to entertain themselves. Keep the child within your eyesight but do not engage with them. Set a timer (5 minutes or so) and then take them out of the zone. Do not sound angry or frustrated with them.
2. Reward for good behaviour
Set up a calendar and make a note of the good and bad actions done by the child. For every good behaviour give a point, and for every bad behaviour deduct a point. If the good points outnumber the bad ones by 5 or so, reward your child. Choose the rewards carefully - like either an ice cream night, or the child gets to pick his favourite dish for dinner that week. Do not go huge or the child might spoil.
