How this lesson connects
Keep using what you learned last class: A revision log is the primary evidence that feedback improved a prototype, because tying each documented change (and each rejected alternative) to a specific criterion proves the improvement was driven by evidence rather than guesswork. Today: Skipping safety testing does not truly speed help, because a failed patient-facing device costs a life rather than money, so the urgency of an innovation never justifies releasing it untested.
Optional: listen or watch a unit review▸

- • This week you present your ER design and then pivot to Problem 2: human physiology.
- • Before the presentations, you will debate one of the hardest questions in medical innovation: how much testing is enough?
- • The answer has real stakes -- it will also apply directly to whatever you propose in your own innovation work.
- • Today's debate is both a Monday ritual and a warm-up for the evidence-based arguments you will make in your presentation.
- • How to argue a position on the tradeoff between innovation speed and patient- testing requirements.
- • How testing requirements function as constraints on any medical device or protocol.
- • How connecting a debate argument to your own prototype evidence strengthens the claim.

A revision log is the primary evidence that feedback improved a prototype, because tying each documented change (and each rejected alternative) to a specific criterion proves the improvement was driven by evidence rather than guesswork.
Skipping testing does not truly speed help, because a failed patient-facing device costs a life rather than money, so the urgency of an innovation never justifies releasing it untested.
A review board sorts scientific evidence, stakeholder needs, possible benefits, possible burdens, and uncertainty before choosing a policy.
- Which statements are scientific evidence?
- Which statements express a value or priority?
- Who receives the benefit and who carries the burden?
Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
A review-board model organizes reasoning but does not make one ethical principle automatically outweigh every other principle.
- • Evidence cards map to source-backed findings.
- • Stakeholder cards map to affected people and priorities.
- • The recommendation maps to an explicit tradeoff with a named uncertainty.
Driving question: For the ER prototype your team built, exactly how much pre-release testing is enough before a real patient in a real emergency department depends on it?
What you already know: A revision log is the primary evidence that feedback improved a prototype, because tying each documented change (and each rejected alternative) to a specific criterion proves the improvement was driven by evidence rather than guesswork.

Visual or model: F1. F1. A lesson illustration or teaching diagram for Innovation-safety debate. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Trace the labeled system, test, or design relationship and identify which evidence should trigger revision.
- Observe or measure the relevant feature in innovation- debate.
- Organize the observation with a stable evidence ID.
- Apply this rule: Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: For the ER prototype your team built, exactly how much pre-release testing is enough before a real patient in a real emergency department depends on it?
What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.
What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.
- • hypothesis: A testable, falsifiable prediction about how variables relate, written so an experiment can support it or prove it wrong.
- • : The one factor a researcher deliberately changes in an experiment to test its effect on the measured outcome.
- • : The outcome a researcher measures in an experiment, which may change in response to the variable being tested.
- • control: The comparison condition that isolates the effect of the variable being tested by keeping everything else the same.
- • : The number of subjects or observations in a study; larger samples give more reliable results and reduce the role of chance.
Use it now: Choose one decision option. Cite E1 and E3, then explain how the rule connects the evidence to your choice.
Go further, optional: The source links below are optional enrichment. Every fact required for today's local evidence decision appears in this lesson package.
A defensible biomedical decision separates scientific evidence from value judgments, identifies who may benefit or be burdened, and states the uncertainty and tradeoffs that remain.
Limit: Scientific evidence can inform the options and likely consequences, but it cannot choose a single value-neutral answer.
Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
Limit: A review-board model organizes reasoning but does not make one ethical principle automatically outweigh every other principle.
You can argue a position on innovation with evidence.
Limit: E3 defines the classroom product or success criterion. It is not independent scientific evidence and cannot justify a clinical or causal claim.
PLTW-BFH-2027-02-24 · Simulated classroom evidence scenario
Your role: biomedical design team member
Decision: Your team must decide what the evidence from innovation- debate supports before submitting the claim-evidence-reasoning response named on today's page.
- • Release the prototype now, because a device that could save lives helps more people the sooner it reaches them.
- • Withhold your position until you know which failure of your prototype would actually harm a patient in an emergency.
- • Argue that your ER prototype must pass its tests first, and state the delay that choice costs patients.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the claim-evidence-reasoning response.
Claim ceiling: Today's evidence supports a classroom claim about innovation- debate. It cannot prove causation, diagnose a real patient, or justify action outside this room.
Reason for review: Your team must decide what the evidence from innovation- debate supports before submitting the claim-evidence-reasoning response named on today's page.
Context: testing is not a delay on innovation; it is part of the design, because a device that fails on a real patient costs a life, not a return.
- • T1: Prepare two questions about balancing innovation speed with patient .
- • T2: Draft a CER position on the right level of pre-release testing.
- • T3: Debate with peers and capture the strongest opposing point.
- • T4: Connect the debate to your own ER prototype's claims.
- • T5: Submit two questions, one CER contribution, and a reflection.
- • E1: A defensible biomedical decision separates scientific evidence from value judgments, identifies who may benefit or be burdened, and states the uncertainty and tradeoffs that remain.
- • E2: Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
- • E3: You can argue a position on innovation with evidence.
Measurements: Use only the measurements, units, graph, or counts supplied in today's task. No additional patient measurement is implied.
Figure finding: Teaching diagram for Innovation- debate. Trace the labeled system, test, or design relationship and identify which evidence should trigger revision. This is a teaching model, not patient or experimental data.
Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.
Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.
For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.
Mean, median, and range keep the measurement unit. Order the values before finding the median.
Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.
- • The solution must address the stated need in innovation- debate.
- • The decision must be supported by E1-E3.
- • The final product must make the success criteria visible.
- • Complete the work inside the 80-minute block.
- • Use only supplied or teacher-approved materials and evidence.
- • Do not trade , accessibility, or privacy for speed.
- • and evidence quality: must pass before scoring other criteria.
- • User need and effectiveness: highest scored criterion.
- • Time, cost, and ease of use: compare only after and effectiveness pass.
Test evidence: For each option, record the E1-E3 result that supports or fails each criterion. Do not assign a score without a named observation.

Students often think Students often think that if a device could save lives, getting it to patients faster is always the more ethical choice, and testing just slows down help.. The trap: That reasoning is a trap because an untested device that fails does not fail quietly; it harms the exact patient it was meant to save, so skipped testing trades a possible future life for a probable present one.
Worked CER on a parallel case (use this to see the format, not the answer)
Note: this argues a different question than yours. Your task is about how much safety testing an innovation needs. This model argues whether a hospital should require verified hand-hygiene compliance before it opens a new ICU. Copy the structure and depth, not the content.
Claim: A hospital should require documented, audited hand-hygiene compliance from its staff before it opens a new intensive care unit, even when there is pressure to admit patients quickly.
Evidence: Hand hygiene is one of the most studied ways to prevent healthcare-associated infections, and the World Health Organization treats it as a core patient-safety measure. Units that track and post compliance rates tend to sustain higher rates than units that only tell staff to wash their hands. In an ICU, patients are already fragile, so an infection that a healthier person would shrug off can become life-threatening.
Reasoning: Opening a unit fast feels like it helps patients, but admitting sick patients into a space where infection control is unproven trades a short wait for a hidden risk. Requiring audited compliance first means the safety habit is verified, not just assumed, before the most vulnerable patients arrive. The proof does not slow care for no reason. It protects the exact people the new unit is meant to help.
Link to my prototype: my prototype speeds up patient handoffs between units. Faster handoffs are only an improvement if they do not skip the safety checks a slower handoff would catch, so if I claim my design is safe, I have to show that the checks still happen, not just that the clock is faster.
Two questions:
1. Who should audit the compliance, and how often, so the rule stays honest over time?
2. If admitting patients is urgent, is there a safe middle step between opening fully and staying closed?
Reflection: A peer pointed out that a hard rule could delay care during a surge when beds are scarce. I still think verified safety should come first, but I agree the policy needs a clear, pre-planned exception for emergencies so the rule protects patients instead of trapping them.
This model shows the level of evidence and organization needed to complete: A parallel claim-evidence-reasoning model on a different safety question (mandatory hand-hygiene monitoring before a new ICU opens its doors), with a link to a prototype, two questions, and a reflection. It shows the CER format and depth without answering today's own prompt about how much testing an innovation needs.
