Step 1
Start a class
One click makes a class and a six-letter code. Students enter the code on the tutor page.
Or open a class you started before:

Your class
Students go to sheaf.one/school.html and enter this code. Open the student page in another window to try it yourself. Start or open another class · Forget this class
Step 2
Test mode
In test mode the tutor may only explain what a question is asking. Any reply that gives an answer, a method, or a hint is held by the gate before the student sees it. The switch takes effect on the student's next message.
Step 3
Tell the tutor what to know
A note for the tutor about the whole class. For example: "We have not covered surds yet" or "Use metres, never feet". The tutor follows it from the next message on. Notes about one student go on that student's record below.
Step 4
Watch the class
This updates every few seconds. A stuck note names the student, the trouble, and what they tried. A hold shows the reply the gate stopped, and you decide: let the student see it, or keep it held. Click a student to read their record.

How the tutor is checked
Three checkers read every reply before the student does
The tutor writes a reply. Before it reaches the student, three separate checkers read it and Sheaf measures whether they agree. A reply goes through only when the checkers say it keeps the rule. The last check for this class is shown below, and every held reply on the feed shows what each checker said.
The last check
No check yet.
Step 5
When a student is troubled
When the tutor notices a student seems anxious, upset, or says something worrying, a note appears in the feed above at once, marked in pink. Save your email to get every such note by email as well. Save your mobile number to get a text too. Parents set their own texts at sheaf.one/school-parent.html with the class code and their child's name.
Step 6
What the tutors learned from each other
Once a day, every class's tutor is paired with another and reads that class's day: where the tutor gave too much, where it missed a troubled student, which questions worked. Each proposes a few rules of conduct. Sheaf's coherence check screens every rule against the rules already in force and your notes. You accept or reject. An accepted rule is in every tutor's instructions from the next reply.

Nothing waiting.

One student
The thinking record: what the student wrote and what the tutor said. A reply with a pink edge is the line the student saw when the gate held the tutor's reply.

Words and phrases the student highlighted to see in their own language. A word looked up several times is a word to teach.

What the tutor knows about
The tutor builds this picture as they work together: how the student learns, which topics are secure, which mistakes repeat, and what to practise next. It is encrypted, and you can clear it. Clear what the tutor knows
A note for the tutor about
For example: "Peter has not done Pythagoras yet" or "Answer in short sentences".
The mathematics behind it
Three checkers read every reply before a student sees it, and a branch of mathematics called sheaf cohomology asks whether their three readings fit into one whole. The rules of conduct the tutors propose are checked with formal logic, so a new rule that clashes with one already in force is named before you see it.
