Questions About Using IDAS for Teaching

I'm interested in using IDAS for teaching my course. How do I start?

We are glad you are interested in using IDAS for your course! Please read our Interactive Data Analytics Service Documentation in order to find answers to common questions. We are also more than happy to meet and talk through any questions you might have. Please reach out to research-computing@uiowa.edu to ask your questions or schedule a meeting.

If you decide to request IDAS for your course, please fill out the following Workflow form: https://workflow.uiowa.edu/form/idas-class-request.

I've requested to use IDAS for teaching my course. Do my students have to request their individual IDAS accounts?

No, students enrolled in your course will automatically be given access to your course instance on IDAS. Access to the course instance will be automatically adjusted for students who add or drop the course after the semester has started.

However, if you would like to give access to your TA'syour TAs, additional instructors, or students who unofficially audit the course, you need to add them to your Workflow form using the steps herein this article - Add a user to an IDAS class use environment.

I've requested to use IDAS for teaching two separate courses. Will I have separate IDAS instances for those courses?

Yes, each course will have a separate IDAS instance. That means students enrolled only in one course will not be able to see the class materials posted in the IDAS instance for the other course.

I've requested to use IDAS for teaching my course. How long does it take for my request to be approved?

This depends on the complexity of your request. Our Systems Administrator team will build an instance specifically for your course and grant access to students who are enrolled in the course. In general, if you are interested in using IDAS to teach a course, please let us know as soon as possible by filling out this Workflow form: https://workflow.uiowa.edu/form/idas-class-request.

Can I request a shared storage space for my IDAS course instance?

Yes, course instructors can request a shared storage space when they fill out the classroom request form in Workflow. Each course can have a 1TB free shared storage space of 1TB. Please see this article for more information about accessing the class share from IDAS.

Class shares are typically set up using our default permission setting, which allows 1 user to be the owner of the share and have both Read and Write access. The owner of the share will be able to upload and modify files in the class share. Everyone else in the class has Read Only access, so they can read and copy files but can’t upload or modify files.

As an alternative setting, instructors can also request to give everyone in the class both Read and Write access to the class share. That means both the instructor and the students will be able to upload and modify files in the shared class folder. 

At this point we are unable to make more than one user the owner of the share.

charge. 

The class share can be accessed by the instructor, students who are enrolled in the class, and any additional users specified in the classroom request form in Workflow. The instructor can upload class materials to the class share. The materials will then be available to the students and additional users to view and copy to their individual IDAS home directories.

When instructors fill out the Workflow form, they can request one of the following permissions for students:

  • Read/Write: students can view, edit, create, and delete files in the class share. If you choose this option, students can end up removing files from the class share, making those files unavailable for other students in the class. Please make sure this is what you want before you choose this option in the Workflow form.

  • Read Only: students can view and copy the files from the class share to their IDAS home directories. They can't edit, create, or delete files in the class share. They can still edit, create, and delete files in their individual IDAS home directories. This is the option that most instructors choose.

The instructor is the owner of the class share and has Read/Write access. Each share can only have 1 owner.

Please see Accessing the Shared Class Folder for more information about accessing the class share from IDAS.

How long will instructors and students have access to IDAS after the course ends?

We deprovision all course instances on IDAS the week after grades for the semester-length courses are due. To determine when grades are due, please see these Grading Schedules from the Office of the Registrar. Please download any data, codes, and files from your classroom account before access to your IDAS course instance ends.

For more information, please see Class Accounts at the End of the Semester.

Can I continue using IDAS after my course ends?

Instructors and students are welcome to request an individual IDAS research account if they want to continue using IDAS for their own research after the course ends. Note that files in your classroom account will not transfer to your research account. Please download any data, codes, and files from your classroom account before access to your IDAS course instance ends.

For more information, please see Class Accounts at the End of the Semester.

Whom should students contact if they run into issues using IDAS?

Please contact research-computing@uiowa.edu. Students should mention that they are enrolled in a course that uses IDAS, the provide:

  • The full name of the course,
