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)

Oh! These are different because, one is about justice while on the other hand, 12 Angry Men is all about 12 white men who want to get a black boy killed.
