💡 Big idea: Critiquing an existing study is faster and safer than making the same mistake yourself -- learning to identify design flaws in others' work protects your own.

  1. 0-10Introduce the study-critique framework: variables, controls, sample size, and limitations
  2. 10-30Read the provided physiology study summary and annotate design choices
  3. 30-50Critique: identify variable, control, and limitation problems in the study
  4. 50-65Propose your own study design that avoids those flaws: hypothesis, variables, and planned measurements
  5. 65-77Submit the Problem 2 research design ticket
  6. 77-80Exit check: name the most important design improvement your proposed study makes
Mr. Mendoza's 5-minute intro
  • Today you read a short physiology study summary and pull it apart -- not to criticize, but to learn from its design choices.
  • Every flaw you find in someone else's study is a mistake you will not make in your own.
  • Then you will propose a sound design of your own and document it as your Friday summative.
  • Study-design critique is a direct skill for the Molecular and Genetic Technology and Microbiology Testing strands of WebXam 072125.
Do this, step by step
  1. 1Read a short provided physiology study summary.
  2. 2Critique its design: variables, controls, and limitations.
  3. 3Propose how you would design your own study to avoid those flaws.
  4. 4State your hypothesis, variables, and planned measurements.
  5. 5Submit the Problem 2 research design ticket.
You'll be able to
  • You can critique a study's design choices.
  • Your proposed design controls variables and is testable.
Know by the end
  • How to evaluate a study's variable identification, controls, and limitations using named criteria.
  • How the flaws in a study become the design requirements for a better one.
  • What a sound physiology study design looks like when variables are controlled and the hypothesis is testable.

Evidence-based revision, Q&A, intro to physiology research design. · Research design ticket

Day 5 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.

Do this: Open Problem 2 in your myPLTW course shell and locate the research-design or study-critique activity to review the critique format.

Complete

Mark the research-design ticket activity complete in your tracker after submitting.

How far to get

The Problem 2 variable and hypothesis work is done; by end of today the study critique and your proposed physiology design should be submitted as the weekly summative.

Upload as evidence

Research design ticket with study critique and your proposed design including hypothesis, variables, and planned measurements.

All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.

The plan

Today's PLTW tracker

Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.
