## Understanding Change in Mathematical Thinking: A Perception-Action Perspective

The Illinos STEM Education Colloquium will have featured guest, Dr. Martha W. Alibali, Vilas Distinguished Achievement Professor at the University of Wisconsin-Madison, on Friday, February 2, 2018. The Colloquium events will be held in the College of Education, Room 22, 1310 S. Sixth St, Champaign, IL.

From 10:15 - 11:15AM, Dr. Perry will lead a book discussion of *Why Gesture?*, co-edited by Dr. Alibali. Then, from 12:30-1:30PM, Dr. Alibali will present, **Understanding Change in Mathematical Thinking: A Perception-Action Perspective**. Light lunch will be provided.

This event is co-sponsored by the Mathematics, Science, and Engineering Education program in the Department of Curriculum and Instruction, the Office for Mathematics, Science, and Technology Education (MSTE), and the University Library.

### About Dr. Alibali's lecture

Mathematical thinking involves perceiving mathematical problems and taking actions—both mental and physical—to solve them. Dr. Alibali studies students’ perceptions and actions to better understand mathematical thinking and learning. In her talk, she will illustrate three aspects of her work. First, how learners’ perceptions guides problem-solving actions. Second, that physical actions affect mathematical thinking because mathematical ideas are grounded in physical actions. Finally, how teachers’ instruction guides learners’ perceptions of mathematics problems and their actions. Dr. Alibali’s work helps us understand how perception and action affect mathematical thinking, while highlighting new questions about mathematics learning and instruction.
