Notes from the staffroom.
Grading practice, product changes, and the occasional honest post about what AI can and can't do in a classroom.
The grading pile that never ends
Grading is the invisible second shift — the nights, the weekends, the stack that follows you home. A look at the load teachers carry, and why it is worth taking off their plate.
Read the post →Is AI grading accurate — and can you trust it?
The honest answer depends on what the AI is allowed to decide. When it only reads and your key does the grading, accuracy is something you can check — not something you have to hope for.
Read the post →Share a grade with a parent — behind a PIN, nothing else exposed
A private link and a 6-digit PIN. The parent sees one student’s result, read-only — no account, no app, and nothing else from your gradebook.
Read the post →Grading lab reports without reading thirty of them at midnight
Lab reports are long, structured, and slow to mark. A rubric turns that structure into a grade you can give consistently — and defend.
Read the post →Grading math homework: partial credit, tolerances, and ¾ = 0.75
Math is where photo grading earns its keep: it reads what the student actually wrote, gives partial credit on a worked problem, and knows ¾ and 0.75 are the same answer.
Read the post →No bubble sheets, no answer sheets: grade the paper you already hand out
Most grading tools make you print their form first. SuperGrader grades the quiz or essay you already give — a photo is the whole setup.

If you grade with Scantron-style forms today, here is what switching to photo grading actually looks like — and what stays exactly the same.
Read the post →What we do — and never do — with student work
Student papers are sensitive. In plain terms: where the images go, what is kept, what is encrypted, and what never happens.
Read the post →How long does grading 30 papers really take?
The real cost of a stack is not the minutes per paper — it is the Sunday it eats. Where the time actually goes, and what a tool can take.
Read the post →Grade paper tests online — without typing anything in
Most classrooms still run on paper. You can grade those tests online by photographing them — no retyping, no moving the test onto a screen.
Read the post →Grading when you’re offline — and when the AI is having a bad day
Grading is deadline work. Here is what happens when the wifi drops or an AI provider has an outage — and why your papers are never stuck.
Read the post →Why ¾ and 0.75 are the same answer — and CO and Co are not
How the notation engine decides what counts as the same thing, subject by subject, and why "case is meaning" matters more than it sounds.
Read the post →What "flagged for review" means, and why we never guess
A crossed-out answer is a decision only a teacher should make. How the flag works and what it looks like in the review screen.
