STEM PRACTICE AND EVIDENCE WORKBENCH
Calculate transparent criterion coverage for modeling tasks and prevent a percentage from hiding a missing essential feature.
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
Coverage percentage equals present criteria divided by all entered criteria times one hundred. Ready requires coverage at or above the chosen threshold and zero essential criteria marked absent. Each task uses one repeated claim. The table reports missing essential criteria explicitly so a favorable aggregate cannot conceal a critical modeling-cycle gap. Supported means the local classification matches supplied criterion evidence. Readiness remains a design signal rather than proof of a high-quality learning experience. Inspect mathematical accuracy, openness, usable data, assumptions, iteration, validation, decision context, cultural relevance, time, tools, scaffolds, and multiple ways for learners to engage and communicate.
Confirm the question, source, units, notation, response coding, model assumptions, and review threshold. Keep an unchanged copy of the original evidence.
Run the worked example, inspect every intermediate row, and compare it with a hand calculation, diagram, representation, or approved subject method.
Record the method, assumptions, units, classifications, and flagged rows. Verify the editable report independently before educational or laboratory use.
How to interpret the result
Use during task design or moderation when the modeling cycle should remain visible rather than becoming a single impression score. The analyzer protects essential criteria from being averaged away. It does not determine authenticity, solve the task, measure cognitive demand, validate data, assess student work, or replace curriculum and accessibility review.
The school-water task includes all five criteria and supports ready. The commute task reaches 80 percent coverage but lacks an essential assumptions criterion, so review is supported. The final task also reaches four of five but omits essential validation while claiming ready, demonstrating why an overall percentage alone is insufficient.

Do not mark vague context as authentic, treat a word problem as modeling automatically, omit assumptions or validation, label every feature essential, inflate coverage with trivial criteria, count teacher-provided interpretation as learner modeling, or use the score to avoid reading the task. Moderate criteria and inspect the complete model cycle.
Learning boundary
This browser-local workbench applies only the disclosed rules. It cannot diagnose a learner, certify an experiment, 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 approved school system.
No. It describes entered evidence under one disclosed rule. Review reasoning, uncertainty, access, and several evidence sources.
Treat it as an editable calculation aid. Show your own reasoning, cite required sources, and follow course and academic-integrity rules.
