Dr. Carrie Simpson has made a career of understanding, researching, and utilizing differentiated instruction as part of the foundation for teaching. Her work in the field of gifted education, followed by curriculum development and teacher training in the field of special needs brought her to one steadfast understanding: differentiation is paramount to student success. Currently, Dr. Simpson continues to hone her skills in the craft of differentiation by teaching Humanities courses for Austin Community College, working with the ACC ECHS programs, and through online instruction for the University of Texas at Dallas’ Teacher Development Center, teaching courses on Differentiation for Diverse Student Populations. The Depth and Complexity Framework is a significant part of her work and reinforces her beliefs that potent bursts of excellent instruction help us meet student needs.  She is the author of two J Taylor Education products, CAP and the Depth & Complexity Icons: Empowering Critical Thinking for All Students, and D & C and the 2e: Using the Depth and Complexity Icons to Create Appropriately Challenging Learning Opportunities for the Twice-Exceptional Learner.
