How do you use math in psychology?

This question is on teacher psychology for my information: What could be the possible reasons for a teacher believing in the concept of beating students if given a chance? What could be the possible psychology behind?

When it is said that math is difficult subject, is it psychological or actual?

"Marks don't matter." Doesn’t this phrase make students put their efforts on studies lesser? They proudly say this nowadays. What are your thoughts on this ?

I think education quality is very important because the learning methods of all the children in our class are different, so I will give the opportunity to participate in the activity by bringing all the children of our class to seventy!

According to me, good quality education is one that provides all learners with capabilities they require to become economically productive, develop sustainable livelihoods, contribute to peaceful and democratic societies and enhance individual well-being.
