Hi, Jessica. Honey, I believe you have a good reason to be concerned, even disturbed, by what your child is telling you. #1, any child who feels yelled at by the teacher is not going to be comfortable in the learning environment. If the teacher is, truly, yelling at the kids, this is bad. It's unprofessional, and it's cruel.
I never heard of a first grade classroom where there were so many tests. Aren't they still learning how to read and write in first grade? I would definitely get some answers.
I think you're absolutely right to be in favor of teaching to children's different learning styles. In fact, this is the modern way of thinking, and teachers are being taught to use a variety of teaching methods and appeal to all the senses and all the different ways of learning, all the time.
I don't think it's wrong to be testing kids frequently, but the stress that's put into getting ready for these tests seems wrong. These kids are not in boot camp, and they're not being trained to fight in Iraq, but it sounds like the teacher has this mindset. Definitely get to the bottom of this. Even if the teacher is introducing them to testing to get them ready for FCAT conditions, for crying out loud,the FCAT doesn't come until third grade!
I hope you can get a better teacher for your little one.
Peace,
Syl
