Surge and usability notes

Essential question: Why can accurate public-health information still fail to reach the people who need it during a surge?Enduring understanding: Good information delivered through a hard-to-use interface does not reach people, so usability is part of whether a public-health message works, not an extra.

Mr. Mendoza's 5-minute intro
  • Wednesday your team designs a surge communication app: today's notes give you the principles to justify every design choice.
  • Usability is not aesthetics: it is whether a frightened person in a crisis can figure out the app in 10 seconds.
  • WebXam 072110 connects biotechnology and data handling to public-health communication tools.
  • Finish the PLTW activity today: the platform covers the same usability framework your Wednesday wireframe will use.
Know by the end
  • Mobile surge facilities require usability planning just as apps do: the target user's needs drive every design choice.
  • Core usability principles include learnability, efficiency, error tolerance, and satisfaction.
  • User trust in a public-health app depends on clear language, reliable updates, and minimal cognitive load.

Learn it · deck, reading, and vocabulary
Socratic teaching slide deck

The deck carries the prior idea forward, lets you inspect an analogy, maps the rule to biology, and ends with the same evidence decision and exit ticket used on this page.

Generated from this lesson's canonical data with a red-team citation check.

Carry forward

Where a community sends limited surge resources determines who gets care, so deployment location is an equity decision and not just a logistics one.

Daily take-home

A public-health message reaches people only when the interface is usable, so accurate information in a bad interface fails because users abandon it before they act.

Inspect the analogy

A detective board holds observations, possible explanations, and one next question.

  1. Which notes are direct observations?
  2. Which notes are explanations?
  3. What new evidence would separate the explanations?
Rule

Keep observations separate from explanations, then collect the evidence that can distinguish the options.

Where it breaks

Biomedical investigations use controlled procedures and validated measurements, not intuition alone.

Map the analogy to biology
  • Board notes map to the signs, results and measurements you recorded.
  • Possible explanations map to the competing biological causes.
  • The next question maps to the test or observation that would separate them.
Read this first

Driving question: A city pushes out a correct alert telling residents which mobile clinics are open, but half the people who open the app close it without finding the location. What about the design, not the facts, made a true message useless?

What you already know: Where a community sends limited surge resources determines who gets care, so deployment location is an equity decision and not just a logistics one.

New idea: A public-health message reaches people only when the interface is usable, so accurate information in a bad interface fails because users abandon it before they act.

Visual or model: F1. F1. A lesson illustration or teaching diagram for Surge and usability notes. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Use the labels and arrows in F1 to identify the relationship that supports Surge and usability notes.

  1. Observe or measure the relevant feature in today's lesson.
  2. Organize the observation with a stable evidence ID.
  3. Apply this rule: Keep observations separate from explanations, then collect the evidence that can distinguish the options.
  4. Choose the option the evidence supports and state the limit of the conclusion.

Real biomedical example: A city pushes out a correct alert telling residents which mobile clinics are open, but half the people who open the app close it without finding the location. What about the design, not the facts, made a true message useless?

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.

Vocabulary:
  • : A health system's ability to rapidly expand staff, beds, and supplies to handle a sudden jump in patients during an emergency or outbreak.
  • : Healthcare delivered to people where they are, using vehicles or portable units to reach communities far from a fixed clinic or hospital.
  • : The science of protecting and improving the health of whole communities through prevention, education, and policies rather than treating one patient at a time.
  • surveillance: The ongoing, systematic collection and analysis of health data to detect disease early, track its trends, and trigger a timely response.
  • communication: Sharing information clearly and accurately between people, which in healthcare keeps patients safe and helps teams coordinate care.
  • usability: Use the lesson context and glossary entry to explain usability in your own words.

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.

Evidence set and decision
E1 · Source fact

A biomedical design advances when test evidence is compared with explicit user needs, criteria, constraints, risks, and failure modes, then used to justify a documented revision.

Limit: A classroom prototype, , presentation, or does not establish clinical , effectiveness, manufacturing quality, or regulatory clearance.

E2 · Teaching model

Keep observations separate from explanations, then collect the evidence that can distinguish the options.

Limit: Biomedical investigations use controlled procedures and validated measurements, not intuition alone.

E3 · Task criterion

Name three usability principles relevant to a health app.

Limit: E3 defines the classroom product or success criterion. It is not independent scientific evidence and cannot justify a clinical or causal claim.

PLTW-PBT@P67-2026-12-03 · Simulated classroom evidence scenario

Your role: biomedical team member

Decision: Your team must decide what the evidence from today's lesson supports before submitting the notebook record named on the lesson page.

  • Select the option best supported by E1-E3.
  • Select a reasonable alternative and name the evidence it would require.
  • Delay the claim because the evidence does not distinguish the options.

Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the notebook record.

Claim ceiling: Today's evidence supports a classroom claim about today's lesson. It cannot prove causation, diagnose a real patient, or justify action outside this room.

Math moment
Formula or setup

Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.

Worked parallel example

For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.

Units and reasonableness

Mean, median, and range keep the measurement unit. Order the values before finding the median.

Try it with today's data

Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.

Design record
Criteria
  • The solution must address the stated need in today's lesson.
  • The decision must be supported by E1-E3.
  • The final product must make the success criteria visible.
Constraints
  • 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.
Tradeoff weights
  • 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.

Watch the trap

Students often think Students believe that if the health information is accurate and complete, the communication has done its job and design is just decoration.. The trap: That is a trap, because a message only counts if a stressed person can actually find and act on it. In a surge people are scared and rushed, so a confusing interface loses them before the accurate content ever helps, which means usability is part of the message, not a coat of paint.

Worked example · a parallel case (guides, does not reveal)
Annotated surge and usability notes
Completes: Completes the surge and design note-taking task: three usability principles with examples, a user-needs-to-feature sketch, and one trust-building strategy.

Three usability principles (with health-app examples):

  • Learnability: a first-time user can figure it out fast. Example: a clear 'Find a clinic near me' button on the home screen.
  • Efficiency: frequent tasks take few steps. Example: check wait times in one tap, not five.
  • Error tolerance: mistakes are easy to recover from. Example: a confirmation step before submitting symptoms, with an 'edit' option.

(A fourth, satisfaction, means the experience feels trustworthy and not stressful.)

User needs drive features (sketch in words):

  • User need: 'I do not know if it is safe to go to the ER.' -> Feature: live ER wait-time and capacity indicator.
  • User need: 'I do not speak English well.' -> Feature: language toggle.
  • User need: 'I have no data plan.' -> Feature: low-bandwidth text-only mode.

Trust-building strategy:

  • Show the source and time of every update ('Updated 10 min ago by County Health'). People act on information they believe is current and official, which is critical during a surge.
