Reasoning: connecting evidence to the claim

What separates sound reasoning from bad reasoning, and how do you check your own?

Reasoning is the part where you explain why your evidence supports your claim. It is the bridge. Without it, a claim and some data are just sitting next to each other; reasoning shows how the data leads to the conclusion, often using a scientific principle.

Good reasoning is logical (each step follows from the last), it actually uses your evidence (not just restates the claim), and it considers alternatives (could the data mean something else?). Bad reasoning leans on logical fallacies: jumping to conclusions, confusing correlation with causation, or attacking the person instead of the idea.

Check your own reasoning by trying to break it: state the opposite and see if your evidence rules it out. Ask “what would have to be true for me to be wrong?” If you cannot answer, your reasoning is not finished yet.

Sound reasoning is
  • Logical: each step follows from the one before it.
  • Grounded: it uses your evidence, and names the principle that links it to the claim.
  • Fair: it considers other explanations and says why yours is better.
  • Self-checked: you tried to prove yourself wrong and could not.
Common reasoning traps
  • Correlation is not causation: two things moving together does not mean one caused the other.
  • Hasty generalization: one case does not prove a rule.
  • Ad hominem: attacking the person, not their evidence.
Do this today

Write the reasoning that links your evidence to your claim from earlier this week. Then write the strongest objection to it, and answer that objection.

💡 Big idea: Reviewing your skeletal-unit artifacts cements the connection between bone cell biology, structural anatomy, and the clinical application of repair technology.

  1. 0-8Intro: rubric expectations and packet checklist
  2. 8-30Gather and date-check all three artifacts
  3. 30-50Rubric self-check; fill gaps
  4. 50-65Update weekly tracker
  5. 65-75Write two-sentence reflection: structure and repair
  6. 75-80Submit packet
Mr. Mendoza's 5-minute intro
  • Three big artifacts from this week go in the packet: your bone-cell chart, your fracture table, and your repair CER.
  • Before you submit, read each one. Does every bone cell have a function listed? Does every fracture in the table have a joint identified?
  • Your reflection should be specific. Do not write that you learned a lot. Write how the structure of compact bone relates to how fast a transverse fracture heals.
  • Next week we add muscle to the skeleton. Every term you used this week carries forward.
Do this, step by step
  1. 1Gather your bone-cell chart, fracture table, and repair CER.
  2. 2Check each against the evidence rubric for completeness.
  3. 3Update the weekly tracker with completed tasks.
  4. 4Write a two-sentence reflection on how structure supports repair.
  5. 5Submit the skeletal evidence packet for the weekly summative.
You'll be able to
  • You can assemble a complete skeletal evidence packet.
  • You can reflect on bone structure and healing.
Know by the end
  • Evidence packets require each artifact to be dated, labeled, and rubric-checked before submission.
  • Reflection should connect bone cell function (osteoblast/osteoclast) to the healing stages observed in the fracture data.
  • Skeletal system vocabulary from this week (osteon, trabeculae, callus, remodeling) is directly tested in the Evaluate Body Systems emphasis of the WebXam.

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

Do this: Confirm all Lesson 1.1 Beginning with Bones tasks for this week are checked off in myPLTW before submitting your skeletal evidence packet.

Complete

All tasks show complete status; screenshot included in your packet.

How far to get

By today every task from Mon to Thu this week should be checked off; verify at the start of class.

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.
