LSC Teacher Questionnaire Study: Indicators of Systemic Change - A Longitudinal Analysis of Data Collected Between 1997 and 2003 (183 K)
Authors: Heck, Daniel J.; Crawford, Rebecca A.
Date: June 2004
This study uses questionnaire data to investigate both the systemic impact of the LSC projects and the impact of teacher participation in LSC professional development on teachers' use of the district-designated instructional materials. For projects targeting science in the elementary grades, the amount of time spent on science instruction was also an outcome of interest. A series of two- and three-level hierarchical generalized linear models were used to examine the relationship between teacher participation in LSC professional development, project age, and each outcome variable.
