Protecting Mateo's Hearing
Disease domain · Lesson 13 of 20 · Shared clinical backbone (the cleft team)
Today's goal: Students will explain why cleft palate leads to recurrent middle-ear fluid and conductive hearing loss (Eustachian tube dysfunction) and why the team monitors hearing and uses ear tubes.
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.
For Mateo's parents:
1. 'A muscle near his palate normally opens the Eustachian tube to drain his middle ear, and his cleft disrupts that muscle, so the ear cannot drain and keeps getting infected, like a sink with a blocked drainpipe.'
2. 'When fluid sits behind the eardrum it muffles sound, so he hears soft sounds poorly; this is conductive hearing loss, and his inner ear is fine.'
3. 'To protect his hearing we often place tiny ear tubes that let the middle ear drain and breathe, and I will check his hearing regularly.'
Why test early: 'He is learning to talk during these same years, and hearing loss we do not catch can quietly slow his speech, so I want to find and fix it early.'
Also due today: Mateo's ear disease fits the ordinary mechanics of any cleft palate; on its own it is not a sign of a larger syndrome. The 'about 90% otitis media' figure sometimes quoted in teaching is not in this library, so it is not asserted.
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: Why do children with a get so many ear infections, and how does that threaten hearing?
- 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: As Mateo's audiologist, explain to a parent in three short sentences: (1) why the causes the ear infections (use 'Eustachian tube' and 'drain'), (2) how the trapped fluid can affect hearing, and (3) one thing the team does to protect his hearing. Add one sentence on why you want to test his hearing before he is far into learning to talk.
- 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 "As Mateo's audiologist, explain to a parent in three short sentences: (1) why the cleft palate causes the ear infections (use 'Eustachian tube' and 'drain'), (2) how the trapped fluid can affect hearing, and (3) one thing the team does to protect his hearing. Add one sentence on why you want to test his hearing before he is far into learning to talk.".
- 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.
