There are no short solutions for students who don't get it yet. It's rooted in weak parenting, and to some degree in individual personality, and you don't have any control over that. It is sad indeed, but it's important not to focus on that. Anyone can wake up at any point in their lifetimes and overcome whatever was preventing them from succeeding before then. Your part of it is to plant seeds so that students know where to go and how to approach a transformation when they wake up. As for how to get through your day or make a little progress with these students:
- Keep preaching. They are listening even if they don't act like it.
- Keep seeking tips, strategies, techniques that work even if only for a short time. Observe successful teachers.
- Go with the flow when you can. You can still get something done with talking in the room, or late arrivals, or missing players. It's not perfect, but some days it's all you've got.
How do you deal with students who just don't "get it"? Simple things like be quiet or get to class on time. Showing up.
I feel sad for these kids, their lives are not headed in the right direction.
