Could someone correct this?

To control the students who are ill-mannered (who are having bad habits) has bad habit, I think we, the teachers, should try to build a healthy rapport with all the students right from our first lecture with open-minded conversation with them. can start from a lecture to have fairness with their entire student because Firstly, while treating the students, we shouldn't be baised as such discrimination will have bad impact on them. The ill-mannered students won't get any better with such treatment. They will continue if the student already feel differentiated the will be a with their bad habits student. Secondly, we can should try to make get closer ourselves with to them to know what is happening with them. Maybe, getting closer with to them can make them feel comfortable to share their behavioral problems with us and tell us what is on their minds.
