Online Spaces

  • OpenLab: This website will be the online home for our class. The site contains important information about the course, and will be used in various ways throughout the semester.
  • WeBWorK:  Much of the homework for this class will be completed on the WeBWorK system.  The link to our WeBWorK section and login instructions will be posted on our OpenLab site.
  • Zoom: We will use Zoom for all live sessions. Zoom links will be posted on our OpenLab site.
    • Students who participate in this class with their camera on or use a profile image are agreeing to have their video or image recorded solely for the purpose of creating a record for students enrolled in the class to refer to, including those enrolled students who are unable to attend live. If you are unwilling to consent to have your profile or video image recorded, be sure to keep your camera off and do not use a profile image. Likewise, students who un-mute during class and participate orally are agreeing to have their voices recorded. If you are not willing to consent to have your voice recorded during class, you will need to keep your mute button activated and communicate exclusively using the “chat” feature, which allows students to type questions and comments live.
  • Dropbox: CUNY has provided all students with Dropbox accounts with large storage limits. Information and a login link are posted here.
  • Blackboard:
    • Grades will be posted in Blackboard’s gradebook
    • In case of a Zoom outage or connection problem, our backup for meetings is Blackboard Collaborate Ultra. Log into Blackboard and navigate to our class; the BCU link is on the left. We will use BCO only if we can’t use Zoom.
