racket-autograder-gradescope

Yet another Racket autograder for Gradescope.

Background

Forthcoming.

Basic Setup

1. Create a Racket test/grade file. (See the example below for guidance.) It need not be in this directory.

2. Create any additional files you might need. Once again, they need not be in this directory.

3. Run make-zip GRADE_FILE.rkt [other-files]

4. You should now have a zip file named autograder-NAME.zip.

5. Go to the page for the assignment on Gradescope or create a new programming assignment (see below for details on creating a programming assignment).

6. The second checkbox should be "Configure Autograder". Select that.

7. Upload your autograder. Then click "Update Autograder" (or "Replace Autograder"). It should take a few minutes. Ideally, you'll see a bunch of stuff under "Build Output" and nothing under "Build Errors".

   The "post-installing collections" step in Racket seems to take the longest.

   At some point, it should say "Successfully built ....".

8. Click "Test Autograder".

9. Upload a Racket file and any other files the student might upload.

10. Wait for the Autograder to finish.

11. If things don't go as expected, you may have to debug via SSH. The documentation is at https://gradescope-autograders.readthedocs.io/en/latest/ssh/.

Creating Assignments

Assignment creation in Gradescope is supposed to be obvious. These notes are just to remind us of some common steps.

1. Click on "Assignments" on the left.

2. Click on "Create Assignment" (or "Duplicate Assignment" on the lower right.

3. Click on "Programming Assignment"

4. Click "Next" (duh)

5. Assign one (1) Autograder point.

6. Enable Manual Grading.

7. Fill in the remainder as appropriate. DO NOT enable a leaderboard.

8. We usually end up on a the Outline screen. Add a new question for the human grader. (I usually call it "Human Grader".) It's worth three points for MPs and 0 points for labs. Unfortunately, we can't add the rubric here.

9. Click on "Configure Autograder" and follow the steps above.

10. When the sample grading finishes, you may want to update the rubric under the "Manage Submissions" bubble. We usually use.

    • 1 Some Issues/Needs Revision (R)
    • 2 Meets Expectations (M)
    • 3 Excellent (E)
    • 4 Incomplete, incorrect, or no submissions (I)
