STEM REASONING AND EVIDENCE WORKBENCH
Review staged reductions in supplied solution steps alongside anonymous success evidence for each skill sequence.
Review output
Load the worked example to inspect realistic inputs, or enter anonymous classroom or laboratory evidence. Results remain in this browser tab until you copy or download them.
Transparent method
Support share equals provided steps divided by total solution steps times one hundred. Success rate equals successful responses divided by attempted responses times one hundred. After sorting rows by stage, the sequence meets the rule only when every later support share is no greater than the prior share and every stage success rate is at least the entered floor. A ready sequence satisfies the disclosed numeric rule; it does not show that learners used the intended reasoning or retained the skill. A review status can reflect premature fading, a harder task, unclear prompts, inaccessible notation, insufficient instruction, or ordinary sampling variation. Inspect actual work and restore or redesign guidance before interpreting the aggregate.
Confirm the question, approved source, units, notation, signs, response coding, model assumptions, and review threshold. Keep an unchanged copy of measurements or learner evidence.
Run the worked example, inspect every intermediate row, and compare the result with a hand calculation, diagram, representation, periodic table, or approved laboratory method.
Record the method, assumptions, uncertainty, units, classifications, and flagged rows. Verify the editable report independently before instruction, assessment, or laboratory use.
How to interpret the result
Use when a teacher has designed completion problems or faded worked examples and wants a transparent check that support decreases while success remains above a local planning floor. The analyzer describes the entered sequence. It does not establish causal learning gains, score reasoning quality, compare unequal tasks, prescribe a universal threshold, diagnose a learner, select placement, or authorize removal of accommodations.
Linear-equation examples move from four of four supplied steps to two of four and then zero of four; anonymous success remains 80, 80, and 70 percent, so that sequence meets a 70-percent floor. Stoichiometry support also decreases, but success falls to 50 percent at its least-supported stage, so the sequence is marked for review before further fading.

Inspect actual work and restore or redesign guidance before interpreting the aggregate.
Do not compare different skills as one sequence, treat fewer printed words as less cognitive support, hide unsuccessful attempts, increase task difficulty while attributing the change to fading, use a single class percentage as a diagnosis, remove required accommodations, or fade every step at once. Keep stages aligned, inspect errors, offer self-explanation, and reassess access.
Learning boundary
This browser-local workbench applies only the disclosed rules. It cannot diagnose a learner, certify an experiment, establish a chemical structure, or replace teacher, laboratory, and safety judgment.

Practical questions
No. Processing occurs in the current browser tab. Avoid personal information and retain authoritative records only in the school-approved system.
No. It describes entered evidence under one disclosed rule. Compare several evidence sources and ask for reasoning before drawing a conclusion.
Treat it as an editable calculation aid. Show your own reasoning, cite required sources, and follow the course method and academic-integrity rules.
