2015 CMS Winter Meeting

McGill University, December 4 - 7, 2015

# Schedule - by Session

Detailed session schedules will be posted on the web site beginning in late October. Once the schedules are made available to us by the organizers, we will post them as quickly as possible. Please note that schedules are subject to change without notice. All scientific sessions will be held at the Hyatt Regency Montreal.

 Active Learning in Post-Secondary Mathematics Classroom Org: France Caron (Montreal) and Veselin Jungic (SFU) Faust and Paulson define active learning as "any learning activity engaged in by students in a classroom other than listening passively to an instructor’s lecture." In a growing number of Canadian post-secondary math classrooms active learning is becoming a norm. Flipped classrooms, clickers, games, applets and computer exploration, course projects, problem-based learning, in-class group activities, peer evaluations, are just some of the active learning techniques that have become part of the contemporary learning environment. The main goal of this session is to give an opportunity to its participants to share their own attempts, strategies, successes, failures and conditions for active learning. We will start our discussion with short presentations by France Caron from Université de Montréal and Veselin Jungic from Simon Fraser University.

(undergraduate and graduate) to present a talk on a topic of their choice on December 7th at the Student Research Presentations Session during the 2015 CMS Winter Meeting in Montreal, QC. These presentations should introduce the student’s research to a general mathematical audience. If requested by the presenter, an experienced mentor will be available to provide feedback on the talk. Any questions about the student sessions should be directed to the student session organizers, Svenja Huntemann and Muhammad Khan, at studc-winter15-sessions@cms.math.ca. To register for the session, contact the organizers of the session with a draft abstract by September 25th. Notice of acceptance will be given by September 28th. Abstracts submitted after this deadline will be considered if space remains.
