STEM REASONING AND EVIDENCE WORKBENCH
Group anonymous topic-session dates, calculate consecutive gaps, and review clustering against a teacher-defined band.
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
Dates are parsed as whole UTC calendar days, grouped by exact topic label, sorted, and differenced consecutively. A topic schedule is within band only when every gap is at least the entered minimum and no more than the maximum. Span equals the last date minus the first date. Within-band means the entered dates follow the selected scheduling rule; it does not show that practice was effortful, accessible, interleaved, completed, or successful. Use response evidence and learner needs to adjust future sessions. A same-day gap can represent useful repeated work, but it is visible rather than silently counted as spaced practice.
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 planned retrieval opportunities are massed on one day or separated beyond a chosen review window. It describes a schedule rather than learning effectiveness. It does not select a universal optimum, measure retrieval success, personalize memory intervals, account for absences, or replace teacher planning and learner evidence.
Linear equations has gaps of three and five days, and atomic structure has gaps of two and seven, so both fit the selected two-to-seven-day band. Forces repeats twice on one day and then waits twelve days, so the schedule exposes both clustering and a long delay for teacher review.

Do not treat one fixed interval as optimal for every topic, count rereading as retrieval without evidence, expose individual histories, ignore feedback and success, or interpret a missed date as a learner trait. Define the objective, record the practice type, inspect outcomes, adapt the next gap, and follow privacy policy.
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.
