Reading and writing instruction has moved into every classroom. Changes in the standard course of study require that students read much greater amounts of non-fiction and construct viable written arguments using reason and evidence. Literacy instruction at the secondary level is a challenge even to those who were trained to do it; it can be downright terrifying to anyone else. This seminar will help secondary level teachers support their students’ reading comprehension. Techniques for using writing as a formative and summative assessment—and how to grade it—also will be included. This session is intended primarily for science and math teachers at the secondary level and also would be appropriate for other STEM subjects that incorporate non-fiction texts and writing as a part of the curriculum.
