01
Misconception diagnosis
Every card names the specific fault line in the reasoning and quotes the student words that show it. Not a topic label, a diagnosis.
Features
Grouped by who has to care about it: the teacher who uses it every day, the leader who has to report on it, and the IT team who has to approve it.
01 For the teacher or tutor
Everything here is designed to be read in under a minute, before a lesson, on a phone, without logging into a second system.
01
Every card names the specific fault line in the reasoning and quotes the student words that show it. Not a topic label, a diagnosis.
02
The default tutoring mode never states the corrected value. Switch to a full worked explanation per assignment when a student genuinely needs one.
03
Three or four skills per session, each with Secure, Developing or Not yet, a mastery percentage and one evidence line.
One sentence per session, written to be pasted into a progress report or an email home without rewriting.
A concrete activity with three steps, targeted at the diagnosed misconception rather than at the topic.
Cards group across a class so you can see which eleven students share one fault line and plan two small groups instead of one lost lesson.
Paste or upload the worksheet, the passage or the problem set you already use. There is no content library to adopt first.
Three subject engines at launch, each with its own skill vocabulary. Reading separates decoding from comprehension rather than merging them.
No scores to type, no rubric to fill, no assessment window to schedule. The record is a by-product of the session.
02 For the leader
Growth you can show, sourced from work students actually did, with the reasoning attached so nobody has to take the number on trust.
Each skill carries a series, not a snapshot. Session eight is read against session one for the same student and the same skill.
Every tier exports mastery data as CSV. School and above can schedule recurring reports to a named address.
District tier maps to your standards and exports into the systems your reporting already runs on.
Per-skill documentation with student evidence, produced continuously, so a tiered support decision has a paper trail without a new assessment.
Teacher and Admin on School. District, School and Coach roles on District, so a coach sees a cohort without seeing everything.
90 days on School, two years on District. Who looked at what, and when.
03 For IT and the reviewer
Stated plainly, including the things we do not have. The student privacy page goes through each one in detail.
Reviewer checklist
Six answers, including the one we cannot claim yet
04 Comparison
Category-level differences, not vendor claims. Where a category's answer depends on the specific plan or contract, this table says so instead of guessing. Coeducate is not affiliated with any product named here.
