How to join the Mathematics Department Internal Communication (“the MIC”) site

Hi everyone,

Here you will find instructions for joining the Mathematics Department Internal Communication site. Note that there are two different sites, one for adjunct faculty and one for full-time faculty (instructions for both are below). These sites are private and intended for Math Department Faculty and Staff only. You will need access to your City Tech email to complete these steps.

Step 1. Create an account on the OpenLab.

If you have a City Tech email, you can claim your account by visiting and clicking “Sign Up” (located in the orange box near the top of the screen). For more detailed instructions, check out the help page Signing Up On the OpenLab.

Step 2. Accept the invitation to join the “Math Faculty” or “Math Adjunct Faculty” (Math Dept Internal Communications) site.

You should have received an email with subject line:
[City Tech OpenLab] You have an invitation to the group: “Math Faculty”
[City Tech OpenLab] You have an invitation to the group: “Math Adjunct Faculty”.
Click the link in the email to join the site.

If you did not receive an invitation, please let the department ( know and we will re-send it.

Congratulations and welcome! You are now be a member of the Mathematics Department Internal Communication site / Mathematics Department Adjunct Internal Communication site.

WeBWorK at City Tech (Fall 2021)

This semester WeBWorK will be hosted in-house at City Tech (“traditional WeBWorK”) rather than by an external provider as in Spring 2021 (Rederly).

WeBWorK Faculty Resources

WeBWorK has been at City Tech since 2011, and the faculty-oriented WeBWorK Working Group has many resources including step-by-step tutorials and video walkthroughs for common tasks, whether you are just getting started or already an expert user.

Some of the resources you will find:

Rederly questions and feature requests Spring 2021

We are collecting questions for the Rederly team and providing answers here – this page will be updated over time.

Question: How can I assign only some of the problems in a problem set?

Answer: There are several ways to do this, depending on your needs:

Option 1: Delete the problems you don’t want (note: the remaining problems will be renumbered).

Option 2: Mark the problems as “Optional” and set the point value to 0. The problems will still appear to students, but they will be italicized and will not count count (if you set a positive point value for an optional problem, the points will be counted as extra credit). You can set problems to Optional and adjust their point value in the “Problem Settings” area (see this tutorial on creating problem sets).

Feature Requests: These are things our faculty would like to be able to do on the Rederly system.

  1. Ability to see all the problems in an assignment rendered on a single screen. NOTE: You can view problems one at a time in the Problem Preview Pane or within the Problem Browser.
  2. Fake student account (or “student view” option), so we can see what the site looks like from the student perspective.
    Rederly 1/28: We are adding in a student view for all profs in our next release (likely next week)
  3. When browsing the OPL, it would be great to be able to select multiple problems and add them to a homework set all at once.
    Rederly 1/28: We have some ideas for this in future releases.
  4. Ability to make past homework sets temporarily invisible, e.g. hide access to past homework sets during exams. NOTE: Currently past homework sets are available throughout the remainder of the semester.
    Rederly 1/28: We have a preliminary idea on how to hide / unhide for this purpose and will incorporate in the next couple releases.
  5. Allow the “Show me another” option even before students have completed a problem successfully (e.g. after one or more incorrect attempts).  NOTE: Show me another is currently enabled after a student successfully completes a problem.
    Rederly 1/28: This will likely be further in the future as we want to eventually add a lot of configurability around show me another that will take a lot of time.
