STEM REASONING AND EVIDENCE WORKBENCH
Apply a transparent structural CER rule to anonymous response counts while separating supplied sources from relevant evidence.
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
Let C be true when an explicit claim is present, E be the counted relevant evidence items, and R be the counted reasoning links. Under the selected planning rule, complete equals C and E at least the evidence minimum and R at least the link minimum. Supplied source count is reported separately and bounds E but does not contribute automatically. A supported classification matches the disclosed structural rule only. Complete does not mean correct, persuasive, independent, ethical, or grade-ready; review does not identify a stable learner deficit. Read the response and sources, inspect whether each item supports the claim, test the reasoning warrant, consider alternatives, and apply the full course rubric with accessible feedback.
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 for a quick structural inventory of claim-evidence-reasoning responses before a teacher reads their substance. It can reveal a missing claim, sparse relevant evidence, or absent explanatory links. It does not judge scientific accuracy, evidence quality, logical validity, counterclaims, source credibility, writing quality, originality, language proficiency, learner ability, or final rubric scores.
Response A states a claim, uses two relevant items from three sources, and includes one link, so it meets a two-evidence and one-link rule. Response B has only one relevant item. Response C lacks a claim. The final response has two relevant items but zero reasoning links, so its entered complete classification is flagged for review.
Let C be true when an explicit claim is present, E be the counted relevant evidence items, and R be the counted reasoning links. Under the selected planning rule, complete equals C and E at least the evidence minimum and R at least the link minimum. Supplied source count is reported separately and bounds E but does not contribute automatically.
A supported classification matches the disclosed structural rule only. Complete does not mean correct, persuasive, independent, ethical, or grade-ready; review does not identify a stable learner deficit. Read the response and sources, inspect whether each item supports the claim, test the reasoning warrant, consider alternatives, and apply the full course rubric with accessible feedback.
Do not count every quoted sentence as relevant evidence, confuse a source list with evidence use, count repeated assertions as reasoning, infer quality from length, expose learner names, apply one threshold across unlike tasks, accept a false claim because structure is complete, or let the count replace reading. Annotate claim, evidence, warrant, limits, and counterevidence directly.
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.
