Yeah, well, I'll try to keep it succinct. But I've been in this profession, 49 years, and I have a checkered career in the sense of I've had eight jobs in education, and only one of them existed before I got it. So I've had an characteristically odd career path, but I'm trying to summarize. So I started teaching in 1971, I decided to teach upper elementary grades for two reasons. One, there were lots of jobs available for men in elementary ed, but I didn't have the patience to work with very, very young kids. I mean, there's a special place of heaven for primary grade teachers. Yes, there is I wanted to teach the oldest kids I could teach without having to specialize in a single subject. Because I liked different subjects. I liked making connections among subjects. And I just couldn't see myself teaching six periods of the same thing. Day after day. Early in my career, I got involved in quote, gifted education, and our school district at the time, was picked as one of five sites in the nation to develop model programs for Gifted and Talented Students. This was an early 70s. And I was selected as one of five teachers to work on that. So I got a chance and very young age to work with national leaders, like Jim Gallagher, Paul Torrance, Sandra Kaplan, the top these are the top people in the field at the time, and it was an emerging field make a long story short, my my time and gifted education, we were doing things that today would be called Project based learning, authentic learning, independent passion, project type things. We did Socratic seminars around Junior great books, and so forth. And a lot of higher order thinking and critical and creative thinking was sort of the norm program coordinator in which I worked with 85 schools developing and implementing gifted programs, did this month long Summer Residential Governor's School program in the summer, and then became a program administrator. So now I'm, you know, mid career, I became increasingly of the position that the things that were happening in gifted education, really were important and needed to be spread beyond just the top 3%. Because at the time that this is in the in the mid 80s, that kind of the general mantra was higher order thinking for the very bright and basic skills for the rest. And there was a lot of back to basics, you know, worksheet, low level stuff going on, in general, mainstream education. So I had an opportunity, or somebody actually reached out to me from State Department in Maryland, and asked me, if I would come meet with him for lunch, she said, I have an idea I want to put forth for you. And his idea was, he said to me, the things you're doing in gifted education need to spread. And I have a position at State Ed Department. And I'd like to reserve it for someone who would come in and try to promote that. And it was a perfect timing in terms of where I was philosophically. So I went to state ed in Maryland not to be a bureaucrat, but to work on what was called a thinking Improvement Program. It was tied into the emerging shift from behavioral psychology to a more cognitive constructivist view of learning. So it all fit together. So I worked in the State Department on thinking skill work, broadly speaking. And then when our state like many states, in the early 90s, started on the first generation of standards, I was picked to be on a team of five people to implement Maryland standards based reforms, which involves coordinating the development of Maryland state standards at the time. But the more unique part of that job was we decided that we wanted to to really break the mold on state assessments. So in Maryland for nine years, during the 90s, we had only performance based state assessments. We had no multiple choice items on Maryland state tests for nine years. Now, back to I would say, the pendulum went a little bit too far. Nothing wrong with multiple choice. It just that it Candice has everything. But we had nine years of performance based assessments. My own two children went through Maryland schools during that era. And I saw the impact of those assessments on what they did in school, what they brought home. They were doing a lot more writing. They were doing true reasoning and problem solving and math. They were doing hands on science, because the state was assessing these things. So it helped me understand the power of assessment. If the if they're good assessments, they can drive good teaching and meaningful learning. During that era. I met Grant Wiggins, we had him as a consultant into Maryland because he was working at the time with a coalition of essential schools until It sizer. And grant was one of the people that popularized the term authentic assessment. So we had him in as a consultant, he and I are the same age, just hit it off right away, and got to be friends. And then over a couple of years, I would start seeing grant at conferences, and I was doing some consulting then. And as was he and somebody from the group ASCD, the Association for Supervision and Curriculum Development at the time, got us together for dinner meeting and basically proposed that we collaborate on a book, they thought it was going to be a book on assessment, because that's what we were both concentrating, right? When I met with grant for breakfast the next day and said, What do you think he said, why I'd be open to a book, but I certainly want it to be more than just assessment. And Grant told me that his doctoral work at Harvard was on curriculum. And I said, and I want to focus on on teaching and the kind of, you know, engaging kids in higher order thinking and more, you know, apply the learning instructionally. So, it was at that breakfast meeting that the ideas of UbD were born alone. So it's a long answer, but that was
