Frequently Asked Questions
We'll be using research-based teaching and learning methods in this course, including inquiry-based learning. Many of the course activities will aim to guide you through the process of discovering content, which is known to lead to deeper understanding and retention of course material than the traditional lecture-based model.
You are welcome to work on your own during lecture activities if you prefer. We suggest you at least try working with your classmates for the first couple weeks to see if you find the discussion helpful. You will be expected to collaborate with your groups during tutorial activities.
Makeup work or extensions on assignments will generally not be allowed in this course. There is flexibility built into the course to account for any absences. Please see the "Assessment and Grading" section on our course syllabus for details. To catchup on missed lectures, you may refer to the lesson plan from the day you missed (linked at the top of this page), read the lecture notes, and/or watch the associated lecture recordings available on our Quercus page.
You are welcome and encouraged to attend any of the office hours posted on the office hour calendar above, even instructor office hours that you are not enrolled with. You may also consider posting a question on our course Piazza (available on our Quercus page), or using the resources at the Math Learning Centre.
We ask that you first carefully read the course syllabus before sending any emails. If you have a question about your grade in the course, please reach out to your course instructor. All other logistics related questions that cannot be answered by carefully reviewing the course syllabus should email the administrative inbox listed on the course syllabus.
