💡 Big idea: Design revision is not failure -- it is the mechanism by which evidence improves prototypes, and logging it makes the improvement visible.

  1. 0-10Collect feedback: review peer comments on your floor plan and flowchart from this week
  2. 10-30Log accepted changes: for each revision, record what changed and why (tie to criterion or evidence)
  3. 30-50Log rejected alternatives: note one change you considered but decided against, with reasoning
  4. 50-65Verify that every logged change traces to a criterion or constraint from your design brief
  5. 65-77Submit the prototype revision log
  6. 77-80Exit reflection: which revision do you think improved the design most, and what is your evidence?
Mr. Mendoza's 5-minute intro
  • • This week you built a floor plan and a flowchart. Now you need to document how feedback changed them.
  • • A revision log is not a list of mistakes -- it is proof that your design process is iterative and evidence-driven.
  • • Every change you record today becomes part of your portfolio evidence for Problem 1.
  • • Including a rejected alternative -- and explaining why you said no -- is a mark of a sophisticated designer.
Do this, step by step
  1. 1Collect feedback on your floor plan and flowchart.
  2. 2List each change you made and the reason for it.
  3. 3Tie each change to a criterion or constraint.
  4. 4Note one change you considered but rejected, with reasoning.
  5. 5Submit the prototype revision log.
You'll be able to
  • • Your log links each revision to evidence or a criterion.
  • • You can justify a design change and a rejected alternative.
Know by the end
  • • How to write a revision log entry that links a design change to a specific criterion or piece of evidence.
  • • Why documenting rejected alternatives shows rigorous design thinking rather than indecision.
  • • How a revision log becomes the primary evidence that feedback improved the prototype.
Do the work

Your PLTW work today

Open this PLTW section today

Design brief, floor plan logic, staffing, process flow, safety, and human factors. · Prototype revision log

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

Do this: Open Problem 1 in your myPLTW course shell and locate the revision or iteration activity to review the log format.

Complete

Mark the revision-log activity complete in your tracker after submitting the log.

How far to get

The floor plan, flowchart, and all Problem 1 prototype work are done; today you log the changes feedback drove and submit the weekly summative.

Upload as evidence

Revision log with accepted changes linked to criteria or evidence, and at least one rejected alternative with reasoning.

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.

Use the code Mr. Mendoza gave you, not your name. Saved on this device.

Today's PLTW target

Design brief, floor plan logic, staffing, process flow, safety, and human factors. · Prototype revision log

Open Problem 1 in your myPLTW course shell and locate the revision or iteration activity to review the log format.

The floor plan, flowchart, and all Problem 1 prototype work are done; today you log the changes feedback drove and submit the weekly summative.

This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.
