STEM PRACTICE AND EVIDENCE WORKBENCH
Audit sequenced representation plans for variety, explicit transitions, and recorded accessible alternatives across lessons.
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
A locally ready lesson has at least the entered number of distinct supported representation modes, consecutive sequence numbers beginning at one, every nonfinal row marked linked to the next, and every row marked with an accessible alternative. One repeated claim per lesson is compared with the complete conjunction. Supported means the plan classification matches this disclosed structural rule. A linked flag should correspond to an actual question or activity that asks learners to translate, compare, or explain connections. Review conventions, cognitive load, language, sensory access, learner-generated representations, sequence flexibility, formative evidence, and opportunities to choose a useful form.
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 while designing a lesson that should connect ideas across several forms rather than display them side by side. The workbench checks planning structure. It does not inspect the actual materials, judge mathematical or scientific accuracy, verify the quality of a transition, certify accessibility, measure learning, or prescribe one fixed sequence.
The linear-pattern lesson uses four modes, links each nonfinal step, records alternatives, and supports ready. The particle-model lesson has enough modes but one visual row lacks an accessible alternative, supporting review. The final lesson includes three modes but the first transition is unlinked while it claims ready, so the claim is flagged.

Do not count decorative images as conceptual representations, present several modes without connecting them, assume one visual is accessible to everyone, require symbolic work before meaning is established, duplicate the same mode under different names, or treat a ready plan as proof of learning. Inspect materials and learner transitions directly.
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.
