This is a HyFlex (in-person and online) taught course. Your registration is for one teaching platform only: in-person or online. Please be prepared to attend all days either in-person or online. Contact us if you have any questions or if you need to make a change. 

Registration confirmation will guide students through accessing the Canvas course site.

Students will create and log in to the Canvas course site with a NetID. Course assets such as instructional materials, participation certificates, and course evaluations will be available to all students through the Canvas course site.

The course materials are all digital and only available on the Canvas course website. 

Online attendees will access sessions via the Zoom web conferencing platform. The Zoom link will be provided a few days before the course.

Please watch the email address that you provide during registration for release dates and pre-course information.
