I hear your frustration. I guess the real question is do you have a choice? It was mandated to us, and I felt very similarly to you. I was a successful teacher with great scores, and I felt if it wasn't broke, why fix it? But I like my job, my school, and my district, so I dug in and tried to learn all I can. I cannot say enough how much training helped. It has been a lot of work over the past two years but I'm really happy with it now (we started with writing) so much so that I asked to help pilot the Reading UOS.
So what do I like:
Specifically, I like the logic of the units, and how the reading and writing fit together and reinforce each other. Like BRONX said, you've got to make it your own - the units really aren't a script to read, they're more like an observation of how someone successfully taught this lesson. They are a framework. I like knowing that the lesson framework has been extensively tried out and tested with thousands of students.
I like the focus more on student work and less on teacher talk - on of the most powerful parts of my training was watching a "true" mini-lesson of only six minutes to make more time for independent reading or writing and conferences/small group. (In my district, we have 45 minutes each for reading and writing workshop so time is an issue)
I like that students are invited to a grade level experience in th mini-lesson, but that the real teaching takes place in conferences and groups, which allows you to differentiate up or down according to your needs. It just feels respectful to me.
I like that it's about teaching the reader versus the reading and the writer versus the writing - it's a small but powerful switch to focus on the transferability of strategies. Beers and Probst talk about this transferability in Notice and Note as well.
Like BRONX, I find the passion of everyone at the reading and writing project radiates through their work.
Regarding the jotting: we keep a reading notebook, and I model the teaching point for the day. We go through their jots once a week and the students write a notebook entry based off of them - the teaching points correlate to standards, and the jots are their evidence. If your students have never done this before it takes a lot of modeling and conferencing at the start. They do get better!
Regarding the charts: I have a few laminated poster boards, and some big ol post it's (6 x 9). I write the teaching points on the post it's and up they go on the poster - this is my anchor chart. My handwriting is not beautiful and I cannot draw well at all, but it holds our thinking and that's all that matters to me. I feel about "pretty" anchor charts the way some folks feel about "Pinterest" classrooms.
I take grades from the work they are doing in workshop - one a week, because that's my schools requirement. The units/lessons are correlated to standards.
