What to do if absent- CER:
- Claim, Evidence, Reasoning: make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure, the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities. Find it in Clever with your Microsoft sign-in, right next to Schoology.
Week overview - Validating Your Prototype: literature review, decision matrices, and metrics
Run a focused , build a to choose a design, and define the metrics you will use to prove your prototype works.
- 1Open your design notebook and write the one problem your prototype is meant to solve in a single sentence.
- 2Find three credible sources on your topic and write one fact from each, noting whether the source was peer reviewed.
- 3Build a with your top design options as rows and your criteria as columns, then score each cell 1 to 5.
- 4Circle the option with the highest total and write one sentence on why the matrix supports that choice.
- 5List two measurable validation metrics (a number you can record) that would show your prototype is working.
- 6Draft a simple : what you will measure, how many trials, and what result would count as success.
- • You will be able to summarize credible sources and tell peer-reviewed work from opinion.
- • You will be able to use a to justify a design choice.
- • You will be able to define measurable validation metrics for a prototype test.
Daily lessons this week
Open any day for its full lesson, the work due that day, and guided notes.
Three-sentence reflection: which source type you trust more for prototype validation and why.
Three-source with citations, main claims, conflict notes, and a synthesis paragraph identifying a design gap.
Weighted with three options, four criteria, weights, scores, weighted totals, and a written justification.
Validation plan with prototype claim, two measurable metrics with units and pass/fail thresholds, a control, a test procedure, and one error-reduction step.
Audited Problem 3 tracker with status for every deliverable, all three artifacts attached, and one improvement note for the next marking period.
Quick intro to the week
- Hook: real innovators do not guess whether their idea works, they measure it, and this week you learn how.
- Today's goal: turn a pile of ideas into one defensible design with a behind it.
- Monday bioethics debate ties in: is it ethical to cite a source you never actually read?
- Reminder: your graded and validation plan are submitted on the class site.
Your PLTW coursework this week
Do this: Advance your PLTW innovation benchmark by completing the and for your prototype in the online course shell.
- • A gathers and summarizes credible prior work before you design.
- • A scores options against weighted criteria to support a choice.
- • Distinguish peer-reviewed evidence from unreviewed claims.
- • Define measurable validation metrics for a prototype.
📋 PLTW evidence due: a summary, a scored , and a prototype validation plan in the course shell.
All PLTW activities are completed inside the PLTW course environment: this page only gives direction.

Fiction. There is no such student. The lessons, labs and dates are the real planned course; the student, the classmates and the conversations are invented.
Lab day: what to bring & watch
This explainer accompanies the PLTW lab protocol: watch it before lab.
What to do when absent
Most days, this class is your PLTW coursework: and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.
Open Clever, then myPLTWHow to get there: open Clever and sign in with your Microsoft (district) account. Both myPLTW and Schoology are in Clever. Do the activity in myPLTW. Turn the work in on this site or hand it to Mr. Mendoza, because that is the step that counts as submitted. Schoology only shows your report-card grade later.
You can't do those from home: do this instead: Simulated validation plan.
Class still runs. A substitute will post today's plan: complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
