Aaron Brakoniecki
Program Director, Mathematics Education
Senior Lecturer
Dr. Aaron Brakoniecki is a senior lecturer and program director for the Mathematics Education program at Boston University Wheelock College of Education & Human Development. He currently teaches mathematics education courses to prospective and practicing middle and high school mathematics teachers. His research focuses on preservice teachers’ mathematics knowledge for teaching and the impacts of technology on that knowledge. Other areas of professional interest include supporting teachers’ uses of technology in their classrooms, the use of concept maps as a formative assessment tool, preservice teachers’ understanding of trigonometry and proportional reasoning, and the reading of geometric diagrams in mathematics texts.
Dr. Brakoniecki’s teaching primarily focuses on content courses for teachers (both secondary and elementary). These courses focus on the big ideas of content domains, exploring the content in deep, connected ways, along with implications of manipulatives, technology, standards, and curriculum in the teaching and learning of this content. Additionally, these courses investigate the ways in which different curricular approaches support the mathematical development of diverse learners.
