How does Gradescope use AI to assist in grading?
TEP has been told by Gradescope that its "AI" is just applied optical character recognition (OCR). OCR scans text in an image or a PDF and turns it into digital text. Gradescope then matches short text phrase between students to form groups of answers.
For example, your quiz has a hand-written, fill-in the blank question to name the first US President. After you upload a scan of your students quizzes and you let Gradescope group students answers on this question for you. Gradescope's "AI" would be able to match text and identify that
- 11 students wrote "Washington",
- 6 students wrote "George Washington",
- 2 students wrote "G Washington",
- 1 student wrote "George W. Washington",
- 1 student wrote "George Wasington",
- 1 student wrote "Ben Franklin", and
- there are 3 answers that Gradescope did not understand (so you will need to figure out what it says).
That is all the "AI" does. It does not appear to do any other analysis of answers. You must double check the grouping done by Gradescope (you can reassign answers to different groups, create new groups, combine existing groups, etc. as needed), and then you must assign a grade and feedback to that group. All Gradescope's "AI" does is form the original groups by matching short phrases, words, letters, or numbers.
This is helpful because's Gradescope's OCR is robust. It does a very good job turning short hand-written answers into digital text. It struggles, just like you might, if student handwriting is not clear. Gradescope has had this ability for many years before "AI" became a thing. It's now called "AI" because that is what is currently marketable in the tech-world.
Should I allow regrade requests in Gradescope?
It is good practice and can be useful to you. Students will probably email you anyway if you've made a mistake in grading them. Using the regrade requests in Gradescope keeps a record of student requests (and your replies to them) in Gradescope, rather than spreading individual student emails about it throughout your inbox.
If you allow for regrade requests, you should let students know about them. Leaving them for students to discover on their own may unfairly benefit students who do happen to know about them. Students who don't know about them may not have the same access to fixing their grade if you've made a mistake while grading.
When communicating with students about regrade requests, you should be clear that they are for fixing mistakes in grading they've found. For example, maybe you overlooked a section of their answer that had key information, just clicked the scoring option when grading, or you didn't notice their answer continued on a second page. The regrade requests should not be used for students to argue their answer is better than you think it is and they should get get points. If students want to discuss the quality of their work with you, doing so in person during office hours or a meeting is a better route than using a regrade request.
Can I use Gradescope if I don’t use a rubric to grade my student’s work?
You certainly have some rules you use for grading, even if it’s not a “traditional” rubric arranged in a grid. Gradescope calls all grading rules a “rubric.” All of these examples are possible grading strategies and how you could use of Gradescope's rubric for them.
- If you ask students to solve problems, your rubric in Gradescope for each problem may just be a list of common errors students make and the number of points they’ll lose for making that mistake. As you grade, you just select what errors students made (or select a “-0 points, excellent work!” option).
- If you have students answer multiple questions choice questions, your rubric in Gradescope maybe have one entry for each answer choice that describes why that answer is right/wrong along with a score. As you grade, you just select the matching rubric entry to a student's answer. When students review their grade, they’ll see that their answer of D earned 0/1 points and see your note for why D was incorrect.
- If you have students complete short answer questions, you rubric in Gradescope may be a list of the key ideas students need to reference along with a point for each one. As you grade, you just check off which ideas appeared in the answer.
- If you use a traditional rubric to grade essays, projects, etc, you can build your rubric in Gradescope as a grid or as a list of rating descriptions grouped by the criteria they evaluate. As you grade, you can select items in the rubric just as you would on paper or in Canvas's SpeedGrader.
Even though most of these are not "traditional" rubrics, all of them can be set up to grade using Gradescope's "rubric" structure.
Can I copy work that students submit in Canvas into Gradescope?
No, there is no "import student work from Canvas" feature. If you've set up an assignment in Canvas to use Gradescope, there shouldn't be a way for students to submit anything to that assignment in Canvas.
A student could, though, accidentally upload a Gradescope assignment to a different Canvas assignment. To fix that, you could manually fix it for them by downloading their assignment from Canvas and re-uploading it to Gradescope. You could also reach out to the student and ask them to correct their mistake themselves. If the deadline for the assignment has passed, you can give them an extension to resubmit the work.
Does Gradescope check if students copied work from other students?
In general, no. Gradescope doesn't "read" student work except for identifying short phrases for fill-in-the-blank questions. However, for programming assignments only, Gradescope does offer a code similarity check tool.
Does Gradescope check if students used AI, copied answers from somewhere, or otherwise plagiarized?
It does not.
