This is an OK introduction, but with a few changes it could be better. I'll bold the sentences that I think need revising.
My name is Ali, and I am in your COM-111-015 course on Monday and Wednesday at 1 pm. I am a freshman elementary education major. I have some experience in public speaking, as I have taught in an elementary school classroom and have done a few speeches in high school. On I scale of 1-10 I rate my public speaking competency at a 6, I am not extremely confident speaking around others and I sometimes get nervous. Throughout high school, I was involved in Girl Scouts and worked as a nanny and babysitter. I am also a member at ........ catholic campus ministry. Overall I hope that this course will make me a more confident public speaker. My dream job is to become a teacher in a 3rd through 5th grade classroom teaching math and science.
I think you should add an ending sentence that goes something like this:
Hopefully by taking your course, I am able to achieve it. (It being your dream job)
The figurative language is “like a ball”. It’s an simile since he’s comparing the fall to a rolling ball. Well he’s comparing the way he fell like an ball rolling down the stairs.
A literary movement is used to describe a trend in literature that is characterised by the shared assumptions, beliefs and practices of an influential group of writers. A literary movement consists of pieces of literary work from different authors but usually in the same era. They are all considered as a part of one literary movement because of similarity in ideas.
