The Adolescent Literacy Collaboratory is one model for sharing literacy leadership responsibility at the secondary school level. With the help of computer technology (PCs), it brings teachers and literacy leaders from multiple departments and multiple schools together to learn from and with one another in overlapping professional learning communities (PLCs). The Collaboratory was developed in 2003 at The Education Alliance at Brown University to help middle and high school teachers of math, science, social studies, and English language arts improve their students' learning through the use of research-based literacy instruction strategies. Since it was piloted in 2003-2004, the Collaboratory model has been refined each year based on participant feedback and evaluation results. Several findings from these sources--including preliminary findings from a study of the program's impact on student reading skills--have more general implications for the structure and process of literacy coaching at the secondary school level. These are shared in this paper. (Contains 1 figure and 1 table.)
