hi everyone, new teacher here. This is my first year teaching and I currently teach all high school levels but my problem is with my freshmen. We've been in school for two weeks, they know me pretty well. I've been really nice and approachable. I've also made an effort to get to know them and their interests. So the first couple of weeks I didn't mind spending some class time talking about things not related to school, I wanted them to see that I was interested in them and not just in their test grades. This has had two effects. #1, they walk into my class and exclaim how happy they are to see me, how happy they are to be in my class, how much they love my class and love the way I teach, that I'm the only teacher that really pays attention to them and helps them learn material and etc. All of those comments obviously make me feel warm and fuzzy inside. #2. They don't seem to respect me. I think they see me more as a friend than a teacher (I'm 25 btw). One student says "hey girl" whenever she sees me, which I don't mind but I'm guessing my administrators would. Today, students were looking me up on social media before class and looking at my pictures and commenting on them throughout class even though I kept telling them to put their phones away. They are soooo loud, I have to quiet them repeatedly throughout class, there's always side conversations, it takes me at least ten minutes to actually get class started, they always ask questions that don't relate to the content to try and get me off track, I could go on and on. These are sweet kids and I've never been the mean type that can discipline someone but they just don't seem to care if I tell them to be quiet. Any advice?? Particularly from teachers who are also known as the "sweet/nice" ones. I don't have the personality to be strict or mean. I've been considering giving them detentions next week if they don't settle down but id like for there to be a step before that.
