Designing custom AI scoring and personalized homework creation UX for teachers

b2b && edtech && ai && 2026

Fermi AI is a brand-new K-12 classroom product. I focused on the two AI-powered flows at the core of the teacher experience: a scoring rubric teachers shape themselves, and homework personalized for every student from a custom question bank.

Students use AI to skip thinking. Fermi's smart canvas flips that: students solve by hand while the AI watches every stroke, guiding without solving. The teacher app adds full visibility across classes, homework, tests, and analytics.

Beta User Research with Partner Schools

Teachers had no control over how AI scored student work
Every student got the same homework regardless of where they were
Students and teachers had fundamentally different needs from the same platform
We shipped under tight constraints that shaped every decision
Students get marks deducted for using a different solving method than their teacher taught.UXR
12th-grader worried about AI grading: 'variation in teacher-dependent correction styles.' Generic rubric fails.UXR
One student loses marks for a different method. Another's teacher grades differently. A third expects specific steps.UXR
Custom rubric: teacher says 'solve by factoring, not formula.' AI scores that approach, not generic right/wrong.PD
58% of beta users hit OCR errors. If handwriting is misread, the rubric grades the wrong thing.Dev
AI Engineer: error-dot system adapts to teacher rubric. Generic right/wrong becomes three scoring dimensions.Dev
Teachers assign the same worksheet to 35 students, only finding out who struggled after the exam.UXR
Physics teacher assumes class knows Integration. Their math class hasn't covered it yet.UXR
Day 0 activation: 6.2% organic vs teacher-driven users who had a task from day one.PM
Teacher-assigned HW solved activation: teachers pushed specific problems, removing the biggest funnel friction.PD
Question completion held at ~20% under 10x growth. Solving worked, friction was reaching the first question.PM
Help chain: self, textbook, friend, Google, ChatGPT, teacher. Most trusted, least accessible.UXR
One student (JEE AIR 362) avoids teachers. 'Gets yelled at for asking.' HW feedback is the only touchpoint.UXR
Pill CTAs + encouraging tone for students. Rectangular controls + data-dense layouts for teachers.PD
Students study in 3 contexts: school, tuition, self-study. 94% of doubts resolved unsupervised.UXR
Tutor flow: teach, example, assign practice. Homework builder mirrors this, personalized per student.PD
36+ students, 3 research phases. 13 diary entries. 5 boards: CBSE, ICSE, State, IB, Cambridge.UXR
PM prioritized homework manager as P0. Teacher referral was the highest-converting acquisition channel.PM
Teacher HW flow shipped Jan 5 to 12. Teachers assigned, students pushed in, 1,328 signups in one week.PM
Custom rubrics give teachers agency over what AI values, rebuilding trust in automated grading.PD

Rigid AI Scoring

Every assignment was scored the same way. Teachers couldn't shape what the AI valued, and students only saw a number with no context for what it meant.

Stepper Controls
Precise 5% increments in a compact control, slower for large weight changes.

5% steppers gave teachers enough precision to express what mattered, without the overhead of getting it exactly right.

Scaling Personalization

In a class of forty, every student was in a different place. Personalizing homework meant picking questions by hand, so most teachers gave everyone the same worksheet.

direction 1
Pick Every Question Yourself
AI organizes the question pool, but the teacher picks each one. 'Yourself' makes it clear who's in control.
Curate
Control
direction 2
Review What AI Grouped
AI clusters students by mastery and assigns their questions. The teacher only reviews the output. 'What AI Grouped' names the artifact, not the task.
Delegate
Verify
direction 3
Resolve Gaps, Student by Student
The table shows names, not topics. Click a name, see the gap, fix it, move on. 'Resolve' signals fixing, not building from scratch.

Personalised homework, from assignment to assessment

Direction 3 matched how teachers already think: one student at a time. Fermi auto-filled PDF gaps from its question bank, shifting the work from teacher to platform. Grouping by level hid individual differences; topic pooling demanded too much selection. A per-student view surfaced what teachers already tracked in their heads.

Qualitative outcomes from pilot study

Personalised Homework Piloted with 50 students and 4 teachers across two US schools. Instead of one shared worksheet, each student got homework targeted to their weak spots. Fermi's AI flagged the gaps; teachers shaped what came next.

Custom Scoring Rubric Teachers set the grading rules: solving method, steps shown, partial credit. They trusted scores because the rules were theirs. Students trusted them because the calculation was visible. The AI applied the standards consistently.
