A conversation on implementations of inquiry-based learning techniques (Panel) | |

Org: Camelia Karimianpour and Stan Yoshinobu (University of Toronto) | |

Inquiry-based learning (or IBL) methods have been implemented in many different forms, from small proof-based undergraduate or graduate courses, to large first-year courses, and in K-12 math classes across North America. In this panel, we will hear from faculty with a diverse set of experiences about how they implement IBL during the first hour, and then break into smaller “round-table” conversations for the second hour. All math instructors interested in IBL are welcome to attend.
Panelists: Deborah Hughes Hallett, University of Arizona and Harvard Kennedy School How to get students started Gavin LaRose (virtual), University of Michigan Student Buy-in Cindy Blos, University of Toronto Identity and Ownership Stan Yoshinobu, University of Toronto, Identity and Ownership Camelia Karimianpour, University of Toronto IBL for proof-based courses The purpose of this panel is to initiate a conversation among those of us who have been practicing IBL in our classes and those who are interested in doing so or are on the fence to exchange ideas, and concerns and explore solutions that may be applied in a variety of settings. We would like to know more about the background and interest of our audience, so that we can tailor the session to your needs. If you are planning to attend our panel, and/or the round table discussions, please take a minute to fill out this form. (https://forms.office.com/r/M2LtjKmFuE) | |

This session will examine aspects of Combinatorial Game Theory and Pursuit-Evasion Games research.
Combinatorial Game Theory is the study of two-player games with perfect information and no chance. It is an active research area intersecting combinatorics, algebra, and theoretical computer science. A pursuit-evasion game is about how to guide one or a group of pursuers to catch one or a group of moving evaders. The geometric formulation of the pursuit-evasion game is called continuous pursuit-evasion, while the graph formulation is called discrete pursuit-evasion or graph searching. One of the goals of their study is to find the winning strategies of the players as well as the optimal number of players to win the game. The main goal of this session is to bring together researchers in combinatorial game theory and continuous and discrete versions of pursuit-evasion games to disseminate their latest work. Applications to speak by all researchers welcome. This session may be accessible to undergraduate students. | |

Design theory and graph decomposition | |

Org: Andrea Burgess (University of New Brunswick), Peter Danziger (Toronto Metropolitan University) and Alice Lacaze-Masmonteil (University of Ottawa) | |

In 1850, Reverend Kirkman proposed the following problem. Fif- teen children are to walk to school three abreast and once a day for seven days. Can they be arranged so that no two shall walk abreast twice? Known as the Kirkman’s schoolgirl problem, this problem is one of the first scheduling problem solved as a design theoretic problem and as a cycle decomposition problem. Since Reverend Kirkman proposed this famous problem, design theory and cycle decomposition have grown into rich and vibrant areas of combinatorics. The purpose of this session is to showcase recent results on topics such as games on designs, cycle decomposition of graphs and directed graphs, path decomposition of graphs and directed graphs, coloring of cycle systems, triple systems, covering arrays, latin squares and other topics in design theory and graph decomposition. | |

Interplay Between Analysis and Convexity | |

Org: Michael Roysdon (ICERM, Brown), Deping Ye (Memorial University) and Yiming Zhao (Syracuse) | |

The field of Convex Geometric Analysis is one which has become very rich in recent years owing to its unique blend of the fields of Convex Geometry, Functional Analysis, Harmonic Analysis, PDEs and Probability. Convex Geometric Analysis concerns the study of convex bodies in finite dimensional normed spaces and linear invariants associated to them. Many problems of isoperimetric type (Busemann-Petty Problem, Mahler's conjecture, affine isoperimetric problems, and Brunn-Minkowski type inequalities) and PDEs of Monge-Ampère (Minkowski problems) are actively studied. This session will include reseachers employing methods from functional analysis, PDEs, calculus of variations, optimal transport theory and probability to solve these naturally occurring geometry problems. | |

This session will invite researchers to speak on applications of set theory to a wide variety of different areas such as combinatorics, Banach spaces, operator algebra, topology, dynamics, and ergodic theory, as well as on topics in pure set theory. | |

Skills Coaching in the Mathematics Classroom | |

Org: Tyler Pattenden (King's University College) and Andrew Skelton (York University) | |

In many post-secondary mathematics courses, the focus is squarely on mathematical content, but we know there are far more intangible skills a student develops in the mathematics classroom. The aim of this session is to make those intangible skills more tangible.
The Conference Board of Canada’s Employability Skills brochure lists 16 skills that are needed to improve ability and thrive in the workplace and beyond. Problem-solving and numeracy, typically the highest priorities in most post-secondary mathematical classrooms, are just two of these 16 skills, so how do we explicitly teach and evaluate progress in other skills? Studies have shown that focusing simultaneously on mathematical and other academic skills is invaluable in helping students with the high school to university mathematics transition (Lake et al 2017) . In this session, we want to learn from instructors who have developed tools that help with the explicit, intentional, and targeted teaching and learning of a skill, rather than a mathematical concept. This skill could be, but is certainly not limited to, communication, group work, learning skills, peer evaluation, reflection, goal setting, using multiple representations, or research skills. We are interested in hearing about the development of your tool, any obstacles you faced and how you have or might evaluate the success of your intervention. | |

Sophisticated Stories from the High School Classroom | |

Org: Chris Suurtamm (University of Ottawa) and Peter Taylor (Queen's University) | |

Much has been written about the need to bring more rich, engaging and authentic mathematics into the school classroom. We will invite high school teachers to work with one or two sophisticated math activities in the 2023 winter-spring term, write a report about it—the experience of both teacher and students—and discuss their findings in this session. A collection of suggested problems will be made available to these teachers. We invite faculty and graduate students in mathematics and math education to interact with the teachers and discuss with them the question of what kinds of experience prepare students for success at university. We will be able to give some travel and registration support to any teacher who is interested in presenting or simply attending. | |
