In this webinar, held April 3, 2018, Drs. Amelia Malone and Lynn Fuchs introduce the Taxonomy of Intervention Intensity as a method for systematically selecting an intensive intervention and guide teachers through modifying the intervention based on student need. They provide an overview of the dimensions for evaluating and building intervention intensity and a detailed case study illustrating how a teacher uses the taxonomy to provide data-based individualized instruction in mathematics.
