STEM REASONING AND EVIDENCE WORKBENCH
Audit lesson time and explicit connections across verbal, symbolic, numerical, graphical, and physical modes.
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
Primary minutes are summed by mode and divided by total planned segment time for descriptive shares. Coverage counts modes with positive primary time. Connection coverage counts unique primary and named target modes. Evidence prompts are summed without weighting because their instructional quality must be reviewed directly. Broad coverage and explicit links can support flexible understanding, but counts alone do not show whether translations are accurate or meaningful. A missing mode may be appropriate; an isolated mode may need a comparison prompt. Review actual learner products and accessibility before revising the sequence.
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 to inspect whether a lesson gives learners opportunities to translate among forms, especially in mathematics and science. It does not score teaching quality, require equal time, judge representation accuracy, verify accessibility, observe learner thinking, or decide which modes best fit the target and developmental sequence.
A proportional-relationships lesson moves from a verbal context to a table, graph, equation, and exit explanation. Four modes receive primary activity time, while the explicit connection targets bring all five modes into the network. The report shows time share, incoming links, evidence prompts, and ten unallocated transition minutes.
Primary minutes are summed by mode and divided by total planned segment time for descriptive shares. Coverage counts modes with positive primary time. Connection coverage counts unique primary and named target modes. Evidence prompts are summed without weighting because their instructional quality must be reviewed directly.
Broad coverage and explicit links can support flexible understanding, but counts alone do not show whether translations are accurate or meaningful. A missing mode may be appropriate; an isolated mode may need a comparison prompt. Review actual learner products and accessibility before revising the sequence.
Do not equate more representations with better learning, add decorative graphs without interpretation, switch notation silently, treat manipulatives as self-explanatory, force equal time, or overlook color and language barriers. State what stays invariant, what changes, how scales align, and what evidence learners produce.
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.
