"This study builds upon the AIR Eisenhower evaluation. We have adopted the six quality features of professional development activities as well as the measurement scheme of comparing Year 3 to Year 1 instructional practices, utilizing Year 2 professional development features as the linchpin for change. We go further, however, to obtain estimates of the effects of the full portfolio of teachers' professional development on teaching practice by examining a comprehensive and complete description of each respondent's set of professional development experiences in secondary mathematics and science. To these ends, we developed an innovative approach using teacher logs to capture the full scope of professional development activities that teachers experience over an extended period of time."
