Question
State a decision question that names the changed input and the outcomes to compare.
Free printable classroom resource
Keep a multi-run project reviewable: organize decisions, comparable results, calculations, claims, feedback, revisions, and individual contributions in one compact record.
Direct answer
A business simulation evidence portfolio is a short, ordered record of what a student or team tested, what the model reported, how calculations were checked, which claims the evidence supports, and how feedback changed the work. It prevents a polished final slide deck from hiding weak comparisons or undocumented decisions.
Use this portfolio for a multi-session investigation, capstone, or team project. For a single lesson, the shorter reflection journal may be enough. Neither resource should be graded on simulated profit alone; assess the quality of the question, evidence, reasoning, responsibility, and revision.
State a decision question that names the changed input and the outcomes to compare.
Keep the scenario, time horizon, constants, input change, outputs, and contributor together.
Show one worked difference, rate, margin, break-even, or other relevant check with units.
Link each conclusion to a run and note confidence, tradeoffs, and rival explanations.
Record feedback, the response, and what changed instead of silently replacing earlier work.
| Code | Evidence is ready when... | Common repair |
|---|---|---|
| C — Comparable | The scenario, time period, and all non-tested settings match the baseline. | Repeat the run with only one intended input changed. |
| L — Labeled | Values include measure names, units, run numbers, and contributors. | Add context; do not submit an unexplained number or screenshot. |
| V — Verified | A calculation can be repeated from the recorded values. | Show the formula, substitution, result, rounding, and unit. |
| B — Balanced | The record includes a financial or operating result and a stakeholder, quality, capacity, safety, or responsibility result. | Add the important tradeoff, not just the winning metric. |
| R — Revisable | The claim names uncertainty, a model boundary, and evidence that could change it. | Qualify certainty and propose a test that could challenge the idea. |
These codes are feedback shorthand, not a substitute for comments. A teacher might write “Run 3: C, L; repair V and B” and ask the team to return with a worked calculation and one non-financial outcome.
Ask: What is the decision question? Which one input changes? Which two or three outcomes will you record? What must remain a non-negotiable guardrail?
Ready signal: the baseline and first comparison can be repeated by another student.
Ask: Show the strongest table and one worked calculation. Which claim does it support? What else could explain the pattern? Who or what absorbs the tradeoff?
Ready signal: the team has comparable evidence and a controlled next test.
Ask: Which claim changed after feedback? What is the model unable to establish? Which contribution can each student explain? What would change the recommendation?
Ready signal: the conclusion is specific, qualified, traceable, and responsibly bounded.

Feedback received, from whom, and date:
Our response: accepted partly accepted not accepted, with evidence
What changed and why:
Sources and assistance used: list teammate data, outside sources, calculators, teacher help, and permitted AI assistance. Note what was independently checked.
Every claim points to evidence. Units and run numbers are visible. Calculations can be repeated.
Tradeoffs and constraints remain visible. Feedback and revisions are documented. Contributors are named.
Assistance is disclosed. No private or confidential real-world data is included. The recommendation states model limits.
Project teacher-run scenarios, rotate one operator, or distribute printed outputs. Students can still label records, calculate changes, audit claims, and conduct conferences. Evidence quality does not depend on owning a screenshot.
Provide a partly completed baseline, vocabulary bank, calculator, oral conference, enlarged print, digital fillable copy, or speech-to-text. Reduce the number of runs before reducing the expectation that claims be traceable to evidence.
Name an owner on every artifact and rotate roles. At the final conference, randomly select one claim, calculation, and revision for each student to explain. Shared evidence is acceptable; invisible contribution is not.
Require repeated trials, sensitivity analysis, uncertainty ranges, a rejected claim, and an evidence map that distinguishes simulator output from outside research. Ask which omitted real-world factor could reverse the conclusion.
Include the decision question, baseline, comparable run records, calculations, claims tied to evidence, feedback and revisions, source or assistance notes, model limitations, and a final recommendation audit.
A reflection journal captures individual thinking at key moments. An evidence portfolio organizes the artifacts that support a longer project, shows how claims changed, and gives teachers a compact record for progress conferences and assessment.
Teams may share run data and a project map, but every artifact should name its contributor. Each student should also explain one claim, one calculation, one revision, and one limitation independently.
Use a two-minute launch check, a mid-project evidence conference, and a final audit. Frequent short checks catch incomparable runs and unsupported claims before students build a final presentation around them.
No. A labeled table or teacher-provided result record can be more accessible and easier to compare. If screenshots are used, students should add the scenario, run number, date, changed input, and a written explanation.
Use the assessment and feedback toolkit to choose the right checkpoints. Start with the copy-ready assignment or three-session team project, assign responsibilities with the team role cards, use the teacher observation and evidence-conference toolkit while teams build this portfolio, collect individual thinking in the reflection journal, challenge draft claims with the peer review and revision protocol, discuss conclusions with the debrief guide, and score the finished reasoning with the 16-point rubric.
