SUBJECT: ILAS Education Committee (ILAS-ED) Monthly Linear Algebra Education Seminar

The ILAS Education Committee (ILAS-ED) is hosting a linear algebra education seminar. We meet virtually on the first Tuesday of every month at 8am Pacific Time. Each event will feature a 45-minute presentation followed by a social half-hour where participants can ask the speaker(s) questions and visit with other participants. Join us for the opportunity to network and discuss best practices for teaching linear algebra. To suggest a speaker or request a topic, or for more information, please email Judi McDonald at
Our first speaker will be Tuesday, September 7, at 8am Pacific Daylight Time. Our inaugural speaker is Guershon Harel, who will be speaking on
On the Complexity of “Simple” Linear-Algebraic Concepts

Why do students encounter major difficulties grasping seemingly simple concepts, such as “span”, “linear independence”, “basis”, “matrix representation of a linear transformation”, etc.? and what instructional approaches found to be effective in helping students reason linear algebraically? The talk will be organized around two themes: (1) Sources of students’ difficulties, such as inadequate attention to conceptual understanding; hodgepodge of concepts, ideas, and symbolism disconnected from students’ prior knowledge; and lack of concrete algebraic models from which students can abstract concepts and ideas. (2) An instructional approach that puts the students’ intellectual need at the center of the instructional effort.
