This is a user's manual for the externally validated Version 2.0 of the Discourse in Science Inquiry Classrooms (DiISC) instrument. The instrument is best suited for use in conducting research in secondary (grades 6-12) science classrooms that focuses on teachers' instructional practices, but can also be used as a professional development tool for teacher self-reflection and identifying goals for instructional change. The DiISC Version 2.0 is aligned with a model of a scientific classroom discourse community and articulated characteristics of social constructivist lessons in the categories of inquiry, oral and written discourse, and academic language development and essential learning principles.
