Delinda van Garderen, PhD, is a Professor of special education. Her research interests focus on students with learning disabilities, struggling learners, visual representations in mathematics word problem solving, STEM literacy, argumentation, quantitative reasoning, and teacher practice and development. Recent or current research projects include teacher professional development to integrate STEM literacy in instruction, how students and teachers use representations to solve mathematics word problems, student development and intervention in number (e.g., conservation of quantity, numerical magnitude), and use of scaffolding to plan instruction to meet the needs of diverse learners in science. She has mentored doctoral graduate students in educational research training and has prepared many graduate and undergraduate students to be teachers in both general and special education. She has written approximately 50 peer-reviewed articles, one co-authored book, and ten book chapters and has received over $6.5 million dollars on federally funded grants.
