One of my tutoring student's parent advised they will be testing their child to see whether or not there is some type of learning disability. This made me wonder why, I mean, whenever we met she seemed to be doing great! So I inquired a little further. To no surprise I was told that their child had a notoriously known "bad" teacher. But what is a "bad" teacher? If there are several parents complaining that their child isn't learning anything - there's a problem, I your child is suddenly dropping those A's for C's, there's a problem...Parents be on the look out for these teachers!
The rumor mill may actually be true, you might have found yourself with a teacher who isn't interested in making sure each and every child is understanding his/her methods of teaching. Every child is different and learn through different methods. Some teachers just don't feel they have the time to engage each one of them. If your child is suffering in a certain subject or throughout an entire grade year, then the chances are that he/she will not have the ability to keep up the next year. For example, if he/she was unable to truly learn multiplication because of an uninterested teacher, then the next year when they are doing fractions, they will not understand it as easily. Your child will begin to disengage in the new class immediately regardless of who is teaching now because they don't understand from the prior year.
This is not a learning disability so don't make them think they have one. Hear what they are telling you and take action. Take the time to find out about your child's teacher, make parent-teacher conferences, make sure that the teacher cares about your individual child! And if not, you can hire a tutor or if that's not an option, you have the right to request that your child be put into another class. Do not let your child suffer - there are such things as bad teachers out there, so beware!
