 You know I was thinking about that. I was thinking it is it is resource-intensive, but it is Outcome rich, and I think that I mean there is no doubt about it. We have tons of tons of evidence that our teachers are motivated our teachers are are Taking initiative to do things beyond just the one lesson. They're taking initiative to do all kinds of things They're recruiting their peers into the program. They're recruiting principals into their classroom to come observe They're seeing students differently, and that's we really need to talk about that the impact on students is you know with a teacher Is bringing in something interesting and that works and then the students respond positively and demonstrate Skills and abilities that the teacher didn't know they had and so then it's this whole iterative process where You know the teachers are motivated by their kids So when their kids are doing better than the teachers want to do more and We've heard that from more than one teacher. They say wow my kids always want to do this now now. They're asking me Can we do something else like that? So there's all of that, but then there's the CST scores, which are our state scores, you know We have Assessments we've done with our evaluator that to show student achievement goes up and we can demonstrate that in several different ways student engagement goes up teacher The abilities the ability of teachers to apply the historical thinking skills Increases, and I think there's there's really two separate things going on. We have all of this evidence based on feedback from teachers and and Everybody wants to call that anecdotal But pretty soon there's a pattern and pretty soon There's a message that's coming very clearly from teachers that teachers are actually demanding calling their administrators and sending emails to their Administrators saying you know unless you do lesson study. I don't want to do professional development I mean, I really believe that the professional development is Is profound and the leaders in Placer County in the coming years Will be people who say you know that that lesson study thing that because it provided Networking opportunities it provided a clear content focus and a clear focus on Student the student experience student achievements student engagement Examining student evidence all these great things that you want educators to do
