So recently, I have noticed that all my classes are loud and some are quiet. I decided to observe all my teachers except for my 6th period (Lunch betch) and see what i can conclude. Period 1: Ah, first period science, how fun :3. My first period teacher is a female and is very short. I notice that many people are willing to talk back and whisper in the middle of a lecture. Although she tries to manage the class, she doesn't seem to do much. Period 2: Oh boy, Spanish for this period. My Spanish teacher is very tall (HORY SHET 6 FEET?) and particularly skinny. His personality is funny and friendly, but serious at times. While people do talk sometimes, most of the time the class is rather quiet and very outgoing and willing to answer. Period 3: NO ONE LITTERALLY TALKS IN THIS CLASS. Why you must ask? Well, here's the thing. My 3rd period teacher (Mr. Vorhauer, ahah. language arts though) is matched in height with my 8th period teacher. He's also taller than my 2nd period teacher, actually even taller. He's also really fat, and his facial features are intimidating. Period 4: Physical education is rather fun, except for cardio days. Anyway, class is pretty cool, none get in trouble. The teacher is tall and is masculine (With a beautiful orange colored moustache hesagingerifyoucouldn'ttell) Period 5: Design teacher can't manage the class at all, the class is super rowdy. It always takes 5-7 minutes to get started. Seriously, super duper stupid. No one turns in their work except for some and me. This teacher is old and is a female, plus not as tall. Period 7: Class is still rather loud in this class, but not as loud. Teacher is short and is friendly, but can be very stern at times. Otherwise, it's an okay class Period 8: Exactly like period 3 for me. No one talks at all, and the teacher is super tall and fat. No one, and I mean no one has ever gotten on his bad side. Probably because they know that he won't spare them if they dare to talk back or do anything worthy of such suspension. So my conclusion is... To manage a class, you must have certain features in my opinion. You need features like height and size to intimidate a class into the state of being managable. You also need - Ability to be stern at students - Maybe a serious look on your face - Friendly personality to tame thirsty kids into obedience And other stuff. However, this was observed from my perspective, so yours could be different.
