AI is changing how learning happens.Universities still have to prove who learned what.

Students should be able to use AI throughout their work. The university still needs moments where the student explains it, defends it and demonstrates it themselves.

Question one

Can the work still prove the student knows it?

HST 340  /  Water in the WestSubmission 04

The Colorado River Compact allocated more water than the river reliably carries, a shortfall masked for decades by unusually wet years and by states declining to draw their full entitlement. Arizona's junior priority under the 1968 authorization means it absorbs shortages first, which is why the state's groundwater has quietly become a buffer rather than a reserve. Any durable settlement has to price that buffer, not simply reallocate the surface flow.

The paragraph on the left does not change in any of the three cases.

The university sees the same artifact in every case

Nothing in the submission distinguishes the three. The grade book records the same A, and the university has no way to tell which student it just credentialed.

The work can no longer prove who did the learning.

The artifact stopped being evidence.

For a century, captured work was evidence that something happened. That assumption is gone, and it went quietly, inside every course at once.

The assessment problemNot a detection problem

What is at stake

Universities do two things.

01Educate students
02Vouch for what those students know

They educate students, and they vouch for what those students know and can do.

For decades the second job rested on the first. Essays, problem sets, code and exams stood in as evidence of learning, and the evidence was good enough because producing it required the learning. Generative AI severs that link. It does not make students dishonest, and most are not. It makes the artifact silent about its own origin.

Employers have already started reporting the gap between the degree a recent graduate holds and how that graduate performs. The claim is being tested in public, by the people who relied on it.

Question two

So what actually needs to be proven?

Do not ask
Did AI touch this?
Ask
Can this student demonstrate that they understand it?

Move what is being assessed.

A finished document, assessed on its own. It is the same document whoever made it.

"Why did you make this argument?"Two minutes

This is an assessment problem, not a detection problem.

Detection does not solve it. Detectors learn the fingerprints of the models that exist today, and OriginStory's own researchers published the argument for why that does not generalize. Even a perfect detector would only tell you a machine was involved, never what the student knows.

Removing AI does not solve it either. Students will use these tools in every field the university prepares them for, and enforcement moves the work off campus and out of view.

Question three

What does OriginStory actually do?

The student answers

Not yet asked.

"Because the shortfall was never a modelling error. It was priced in politically. If you treat groundwater as a reserve you get the accounting wrong, so I argued the settlement has to price the buffer instead of reallocating the flow."

Does the demonstration show mastery?

Faculty decides

OriginStory does not grade, and it does not detect whether AI was used. It establishes that the enrolled student is the person making the demonstration. Faculty define mastery and design the assessment.

How the proof works

  1. 01

    Present

    Voice and a second signal from the device establish that a live human is present.

  2. 02

    Verify

    The signals are matched locally. The underlying biometric data does not travel to a central database.

  3. 03

    Record

    A cryptographically verifiable record of that moment is created.

  4. 04

    Attach

    The record stays with the interaction or the work, through a recording, a transcript or a file.

Faculty decide where AI is permitted and where a demonstration is required. OriginStory has no view on either.

What it strengthens

A credential is a chain. It is only worth the weakest link.

Every claim a university makes about a graduate rests on the link at the top, and that link is the one AI just weakened.

Link 01
This is the student.
Link 02
This is what the student demonstrated.
Link 03
This is the credential ASU awarded.

OriginStory strengthens the first link, so the claims underneath the credential stay attached to an actual person. Held as a chain rather than a line on a transcript, that record travels with the graduate and the institution keeps the meaning of what it awarded.

The opportunity

Why this matters at ASU.

01

ASU chose to embrace AI early, and that was the right call. Students will use it throughout their learning and throughout the working lives the university is preparing them for.

02

Learning is becoming more digital, more personalized and more distributed. That is the direction ASU chose a long time ago.

03

Traditional identity and assessment methods rely on a controlled testing room or paid remote proctoring. Both are expensive, both are hard to scale, and neither fits that future.

ASU can embrace AI without giving up confidence in what an ASU degree represents.

The check moves inside the learning instead of sitting outside it in a locked room. Students use AI throughout, and the university keeps secure moments to verify individual understanding along the way.

At ASU's scale, online learners included, that makes it possible to widen access to programs while demonstrating exactly what the credential still represents.

After graduation

The same question follows the student.

Is this the person? Can they do what their record says they can do? Résumés, portfolios, coding exercises and interviews can all now be generated or mediated by AI, and employers are facing their own version of this problem about your graduates.

A connection established during education carries into hiring. That is worth something to the graduate, and it is worth more to the university whose name is on the degree.

A university that can prove who learned something is worth more than one that cannot.

That is the whole argument. Everything above is how it is done.
