Teachers get better as they teach. As discussed earlier the teacher learns from their students. Can you imagine a teacher that didn’t consider the students point of view. That would be a boring class and you would not learn a thing. I hate when the teacher is not motivated and bored with their life. It can really harm a students attitude and make them hate school. https://www.teacherspayteachers.com/ is a resource for teachers looking to get materials and ideas on teaching.
