OneClass plugin for Chrome is malware

Canvas issued the following security alert on 12/19/16:

When a user installs the OneClass Chrome extension, it asks for permission to “read and change all your data on websites you visit.” If a user grants this permission, the plugin places a button in Canvas labeled “Invite your classmates to OneClass.” If the user clicks this button, OneClass sends messages to all of the other users enrolled in the course via Canvas Conversations. Each message says:

Hey guys, I just found some really helpful notes for the upcoming exams for Emerson courses at [link redacted]. I highly recommend signing up for an account now that way your first download is free!

We strongly encourage you not to install or use the OneClass Chrome extension and to remove it if they’ve already installed it. OneClass is not affiliated with Canvas in any way. The invitation feature spams your classmates, and the permission the extension requires opens you up to a lot of security risks.

To remove an extension from Google Chrome:

  1. Open Chrome
  2. Click More.
  3. Select More tools > Extensions.
  4. Next to the extension you want to remove, click Remove Remove.
  5. Click Remove.

If an extension has an icon in your Chrome toolbar, you can right-click the icon and select Remove from Chrome.

Median Search Updates

We’re upgrading to a new video hosting platform! Please help us by taking our survey:

Faculty survey

Student survey

The surveys will be active until December 22nd at 12pm. We will share results of the survey right here in the spring semester.

Why get rid of Median?

We debuted Median in 2008 because there were no products available that did exactly what Emerson needed. At this point, the market for educational video streaming has matured and there are many good solutions available.

When is this happening?

ITG is contacting vendors now, and we’ll share their responses in Spring 2017.
Also in Spring 2017, ITG will hold beta testing sessions on campus where faculty, students, and staff can explore and evaluate each video hosting platform (and eat pizza).
Median will still be up and running through Summer 2017. We hope to have new uploads using the new system at that point while still keeping Median running.

When are you turning Median off?

No decisions have been made about that yet.

What happens to all my stuff?

We don’t yet know what the exact process will be for migrating content – it will depend on the system the community chooses. We will make information available as soon as we can!

Who will help me, and when?

ITG and IT will be running all sorts of trainings, as well as helping faculty one on one. Again, stay tuned for details!

What will I like about a new system?

Our hopes for a new system include:

  • Easier and more reliable uploads from anywhere
  • In-depth analytics that include how and from where your audience is engaging with your content
  • Ability to record screencasts
  • Improved branding, like the ability to choose your own thumbnail
  • Integration with Canvas

Excused Assignment Feature

This Saturday, June 27th, Instructure will be bringing a new feature to the Canvas Gradebook that we’ve been hearing faculty request for quite some time. Now, instructors will be able to excuse individual assignments without having to worry about altering a student’s grade. Here is what Instructure says of the new feature:

To excuse an assignment for a student, enter the value of EX in the corresponding Gradebook cell. The Gradebook will reflect that the assignment is excused for the student. Excused assignments are not included in the calculation for a student’s total grade.

Students can also be excused from a Group Assignment; the other members of the group will still be able to view and submit the assignment.

Note: Currently, the Gradebook only accepts a standard Canvas-wide value of EX for assignment exemptions. In phase two of this feature, instructors will be able to choose from a list of statuses for the excused assignment or for a graded assignment, such as latemissingabsent, etc.

When students have been excused from an assignment, they can view the excused status on the assignment submission page, or when they view the grades page. Students who are excused from an assignment will not be able to submit the assignment, though they can still view the assignment details.

In Modules, assignments are still shown as a module item. If submitting the assignment is a module requirement, students can progress through the Module as if he or she had submitted the assignment.

We hope that this makes managing your grades just a little bit easier, and as always, feel free to contact us if you have any additional questions or requests. ITG can be reached via email at or by phoning 617-824-8090.
