Using Instructional Websites to Differentiate When I started co-teaching with general ed science teacher Jamin Mckenzie, our curricular tools were a textbook, spiral notebooks, an overhead and the rare video. Now, going into our fifth year, we have incorporated reflective, deliberate use of multi-modal strategies, frequent formative assessment and a variety of instructional technology into our teaching. But beyond the smart board, document camera and the Flip video, the single most comprehensive differentiation tool we use is our instructional website. in Public bookmarkswith assessmentdifferentiationformativeinstructional_websitesspecial_ed
