Your poast speaks to the issues. Administrations (and society in general) are too damn scared to publicly identify the problem. If there are kids that cause problems in class, they should be removed from class. We should spend less time on those that are not interested in learning so that those that are interested in learning can learn. But to do that, we'd have to get down to real talk. And administrations - mostly white administrators - are too scared to do that.
One of my staff members just had two kids graduate from high school in the last 3 years. Her daughter was a high achiever that was in all AP courses. That is until the school administration felt that the AP courses were not diverse enough. So they proceeded to lower the requirements for AP courses so that the classroom is more diverse. And those kids that were allowed into the class were not high achievers and not interested in performing at a high level. They were disruptive and caused my staff member's daughter to voluntarily leave the AP courses. She was able to get into the college prep courses where that element didn't exist. But there were other high achievers that weren't able to get into the college prep courses and they had to be stuck in the dumbed down AP courses. This is a large part of the problem.
We've become afraid to excel. Because naturally excelling makes those that don't or can't excel look bad. And for some reason, we don't want that. Instead of setting the bar high and attempting to raise up the bottom, we simply move the top down to close the gap. This is one of the biggest problems with public education and one of the biggest reasons my kids will never be publicly educated.
As to your point about Spanish speaking students - think about this. We have to spend money on extra resources for kids that don't speak English instead of just requiring all students in this country to speak English. Think about that.
For the record, just so everyone knows I'm not on a witch hunt, my mom was a public special ed teacher for 40 years and my sister is a public special ed teacher that works with kids with severe and multiple disabilities. She's been in teaching for 20 years. I love teachers. I understand they're in a bad spot. And I feel for them.
@ticket2ride04 asks why we pay so little for teachers. I can't answer that. Should we pay more? Absolutely. But until society is ready to address the real problems - no matter how uncomfortable it may be - those teachers could make millions and little will change with regard to our results.
