Unit learning targets

The student demonstrates the following:

How this unit is assessed

Mastery rubric

Five science criteria plus separately reported integration (Page 3).

Report & visual

A written report plus a graph or table that backs the claim.

Oral check

The student defends the findings out loud and takes questions (Page 4).

Lab notebook

Question, data, and conclusion kept distinct.

How to read a Bright Minds rubric

You are making a decision, not adding up points. For each criterion, decide whether the work is Developing, Proficient, or Mastery — the column language tells you which. A criterion counts as mastered only when the student can both back the claim with data and defend it out loud. Each student has three tokens per term; each token retries one rubric criterion. Approved accommodations, equipment failures, and approved absences are handled separately and do not consume these tokens.

CriterionDevelopingProficientMastery
Clear written reportReport is missing pieces — no question stated, or data and conclusion jumbled together.Includes most parts, but the order is muddled or the method is too thin for a reader to follow.Separates question, method, source, data, analysis and conclusion; labels supplied records and preserves revisions.
Visuals support the claimUses no table or graph, or picks one that does not fit the data.Includes a graph but it is mislabeled, or it does not clearly connect to the point being made.Uses a labeled visual with denominators and relevant groups; does not hide a reversed pattern through selection or pooling.
Oral defenseCannot explain the work aloud, or just reads the report back word for word.Explains the gist but stumbles when asked to go past what is written down.Explains the investigation aloud in their own words and answers questions about any part of it.
Claim–evidence–reasoningStates a conclusion with no data behind it, or lists data with no claim.Connects a claim to data but skips the reasoning that links the two.Links each claim to specific evidence and justified reasoning, distinguishing observed patterns from untested mechanisms.
Responding to critiqueIgnores a challenge, gets defensive, or swaps in whatever answer is suggested.Hears the critique but cannot tell a fair point from an unfair one.Addresses critique with evidence, retains counterevidence and revises an unsupported claim without inventing excuses or observations.
Integration (cross-domain)Makes no supported connection between the source and the science.Uses the source but needs help connecting evidence, writing, or limitations to the science.Independently connects History, Reading, and Writing using a cited source, appropriate evidence, a limitation, and a scientific explanation.
What “Mastery” requires
The student ties every claim to data and its reason and defends the work aloud, answering questions about any part — unprompted.
What does not pass
Reading the report back word for word is Developing on criterion 3 — the oral defense means explaining it in their own words.
Grading it at home

The split between Proficient and Mastery is claim, evidence, reason: a student who ties each claim to a number and a “because” has it. Ask “what’s your evidence, and why does it support the claim?”

Read these before you grade. They show what Mastery and Developing actually sound like, plus the edge cases where you should coach rather than decide on the spot.

Write the revision the new evidence requires

▶ Mastery
In the pilot A has 4/40 failures and B 4/20: 10% versus 20%. The next batch reverses that pattern. I keep both and revise my claim; these records do not show A is reliably better. I cannot infer a manufacturing mechanism from counts alone.
▶ Developing
A had fewer failures in the example I preferred, so it always wins. I hid the later batch and called the inspection result a safety guarantee.

Integration — a claim the source supports

▶ Mastery
The assigned account supports one claim: after thorough handwashing, fever rates plummeted, matching the unclean-hands prediction, while changing labor position did not lower them. It does not describe how other doctors responded, so I cite that claim, note the intervention was not a randomized identical-group trial and do not reduce the reception to one cause. Source: Testing ideas about childbed fever
▶ Developing
“Semmelweis was right.” (No cited claim, evidence or limitation.)

Edge cases — coach, don’t fail

▶ Claim with no reason
Points to the data but skips the “because.” Coach the third step — why does this evidence support the claim? Common, quick to fix.
▶ Caves under any question
Swaps in whatever answer is suggested. Coach telling a fair critique from an unfair one — defend a sound point rather than folding.
