Saying It Precisely, How Surgeons Classify a Cleft
Anatomical domain · Lesson 4 of 20 · Human Body Systems (HBS)
Today's goal: Use the Veau, LAHSHAL, and Kernahan striped-Y systems to classify a cleft, and place Mateo as a complete unilateral left cleft of lip, alveolus, and palate (Veau III).
What a finished product looks like
This is a model of the work you should turn in. Use it to check your own: match the structure and the level of detail, do not copy it. Your wording should be your own.
Veau: III, because the cleft is a complete unilateral cleft of lip, alveolus, and palate on one side.
LAHSHAL (right to left, L A H S H A L): right side intact (dots for L, A, H), central soft palate clefted (capital S), left side completely clefted (capitals for H, A, L). Result: . . . S H A L, a one-sided complete string.
Striped-Y: shade the left lip, left alveolus/premaxilla box, and the central hard-palate and soft-palate boxes; leave the right arm unshaded.
One line to another city: "Veau III, LAHSHAL . . . S H A L, left side: complete unilateral left CL/P, right side intact."
How this was built, step by step
The finished product above did not appear all at once. Here is the path from the question to the turned-in work, so you can follow the same steps.
- 1Start from today's question: How do surgeons classify a precisely enough that the label alone tells another team exactly what they are dealing with?
- 2Work the Model and the Explore questions to reason it out before writing anything.
- 3Pull the specific evidence the product needs from the reading and any database you used.
- 4Write it up in the required format: Classify Mateo three ways and write it into his chart: (1) with a one-sentence justification, (2) a LAHSHAL string filling the seven positions right-to-left (capitals for complete, a dot for intact, central soft clefted), and (3) a shaded striped-Y. Then write one sentence to a surgeon in another city using only your three labels.
- 5Check it against the rubric, then submit.
| Criterion | Proficient | Developing | Beginning |
|---|---|---|---|
| Complete | Every required part of the artifact is present and filled in. | Most parts are present, but one is missing or left blank. | Several parts are missing. |
| Accurate | The science and data are correct and match the evidence. | Mostly correct, with a small factual slip. | Key science or data is wrong. |
| Scientific reasoning (CER) | States a claim, backs it with specific evidence, and explains the reasoning. | Has a claim and evidence, but the reasoning is thin or missing. | Gives an answer with no evidence or reasoning. |
| Professional communication | Clear, organized, and labeled the way a clinician or scientist would write it. | Readable but disorganized or missing labels. | Hard to follow. |
| Submitted | Turned in the right way (Schoology for routine work) and confirmed. | Turned in, but in the wrong place or unconfirmed. | Not turned in. |
- CompleteProficient: Nothing is left blank: the model fills every part of "Classify Mateo three ways and write it into his chart: (1) Veau class with a one-sentence justification, (2) a LAHSHAL string filling the seven positions right-to-left (capitals for complete, a dot for intact, central soft palate clefted), and (3) a shaded striped-Y. Then write one sentence to a surgeon in another city using only your three labels.".
- AccurateProficient: Every number and claim matches the case evidence.
- Scientific reasoning (CER)Proficient: It names a claim, cites the specific evidence, and explains the reasoning, not just the answer.
- Professional communicationProficient: It is organized and labeled like a real chart note.
- SubmittedProficient: It would be turned in on Schoology and confirmed.
