Though Dillon mentions value - added modeling, he says that the Gates researchers use it «as a starting
point,» and spends most of the rest of the piece discussing their use of cameras to capture teachers
in action
in the classroom — they hope to have 64,000 hours of classroom video by the end of the project and have already begun the process of looking for «correlations between
certain teaching practices and high student achievement» and «scoring» the
lessons.
I spend an inordinate amount of time with them and I take them everywhere I go: when I am on a date, they will be there too; they are with me all day when I go from house to house to give
lessons; they are my «business card» when I give a seminar or need to show a customer how to do a
certain exercise; they are my advertising when I want to show people my skills and knowledge; they often will sleep on my bed; they will climb
in my lap when I am typing away at my computer; they will go on every vacation I take (at 2 years of age, Dillon, my Doberman, had over 50,000 miles on him, going everywhere, from Seattle to Mt Rushmore, Yellowstone, British Columbia, Banff and Jasper, Los Angeles, and all
points in between... and about 200,000 miles on him when he passed away at 6 years of age).
