There are some interesting debates on US edutwitter right now. Similar in structure and tone to a lot of the debates that English edutwitter had in 2014-2019.
There are things we got wrong at that time, and I can see them going wrong for the US too.
One is fixating on interesting ideas that are unlikely to work at scale. For example, E-edutwitter got really excited about some strategies like the use of knowledge organisers. They went big, but probably didn't affect all that much and weren't executed well outside of a handful of adherents. I suspect similar is the case for "scripted lessons" and formal Direct Instruction, which is US-edutwitter's current big thing.
The second is harder and it relates to interlocutors. It's really easy to fall into a camp or tribe. Some people are bad faith interlocutors, and need to have their arguments dismissed. But others aren't. They are people who broadly agree with you, but have issues with some of the recommendations, positions amd positionings. We didn't always disagree agreeably with those people, and I can already see some of that happening in the US. Not everyone who disagrees with you is an idiot or evil or whatever. If you sit too securely in your camp, you end up losing quite a lot of valuable insight.
I personally am a lot more chill on here than I was back then, and I really regret that style of debate. I've worked hard on this vice of mine, because I could have learnt more and developed faster. My advice to US-edutwitter: not everyone who disagrees with you is doing it in bad faith. Try and listen and learn. You don't need to agree, but it's worth paying attention.
