Schoolwide literacy--the teaching of reading, writing, speaking, and thinking practices in all content areas--is generally considered an effective, even necessary, approach to addressing the learning needs of adolescents. In early college high schools, which blend high school and college for students who are underserved in higher education, the need to identify and implement effective schoolwide literacy practices is perhaps most urgent. With seed funding from the W.K. Kellogg Foundation, 14 early college high schools have led the Early College High School (ECHS) Literacy Network by piloting schoolwide literacy action plans since 2004. The three science teachers highlighted in this document teach in ECHS Literacy Network schools. Each of them, through a mix of individual research, innovation, and the support of colleagues, has crafted an approach to addressing literacy in a science classroom. Each classroom practice featured has been honed to a point where it is ripe for sharing, and is easily transferable to other content areas. The author encourages readers to use these strategies in their own classrooms and pass them along to colleagues. (Contains 1 footnote and 7 resources.)
