This casebook offers middle and secondary school teachers an appealing framework for "observing" how practicing teachers address the need to teach students in Grades 6-12 content literacy (the ability to learn effectively through reading, writing, and discussion) along with content itself. Through engaging personal narratives, seven content-area teachers from various grades explain how they use reading, writing, and oral language instruction to meet the needs of students in a variety of subject-area classes. Each case is accompanied by a thought-provoking question and a description of the content literacy strategy it addresses; and bolstered by photographs, samples of students' work, and/or teachers' interviews. The final chapter explores ways to observe teachers and compare observations using knowledge gleaned from this volume.
