请帮我修改我写的英文简短介绍信 谢谢你

i'm from .college student这句不要student.
in order to learn more about how to be a professional educator, and to get a new experience as well中，learn应该是learning,get应该是getting.
i will be watching and doint my observation with your children in this semester改成I'll watch and doing my observation with your babies in this semester.
thank you for understanding改成thanks for your nice understanding and big support in advance.
