Fetal-pig dissection defense
This is a live oral exam conducted over a real specimen. The guide hands you a probe and asks you to find structures, name them, and explain what they do — then follows up with questions you cannot rehearse for. There is no worksheet to copy and no answer to look up: you stand at the tray and defend your understanding out loud.
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Location & identification | Cannot find named structures on the specimen. | Finds most structures with hints. | Locates and names structures on the real specimen unaided. |
| Structure–function reasoning | Names parts but not their roles. | Gives function but not why the form fits it. | Explains why each structure's form suits its function. |
| Holding up under questioning | Folds at the first follow-up. | Answers some follow-ups, falters on others. | Handles unrehearsed follow-ups with sound reasoning. |
| Dissection technique & care | Damages structures or works unsafely. | Adequate cuts; some carelessness or waste. | Clean, deliberate cuts that preserve structures and safety. |
| Use of correct terminology | Relies on informal or wrong terms. | Mixes correct and casual terms. | Uses precise anatomical terminology throughout. |
“This is the diaphragm — it separates the chest from the abdomen, so that’s how I know we’ve crossed into the thoracic cavity. I traced this vessel straight from the heart, so it’s the aorta, not the vena cava, because it’s carrying blood away.”
“That’s a lung, I think. There’s a tube there but I’m not sure what it connects to. We just followed the diagram.”
This assessment is AI-proof by design: it happens at the tray, over a real specimen, in real time. No chatbot can find a nerve, hold up under a follow-up question, or explain a cut it cannot see. Mastery is shown by doing and defending — not by submitting.
