Week 6 — Assignment (Adaptive Learning) · "Build the Skin"

Course: Anatomy & Physiology I (BIOL 2301 + BIOL 2101) · Silver Oak University (fictional sample) · Prof. Navarro
Objective assessed: Objective 3 (the integumentary system: skin layers, epidermal strata, accessory structures & glands, functions & thermoregulation) · SLO A (relate structure to function; trace a feedback loop) · SLO B (use anatomical/physiological terminology)
Worth 100 points · Assignments group = 15% of the grade
Format: adaptive learning — you work the problems with your own AI coach, which grades each answer against the rubric, helps you fix what's off, and lets you retry a fresh version to raise your score. You submit the AI's self-scored report (plus your chat link).

Assignment 6 of the term — every instructional week carries one graded assignment (alongside that week's quiz, discussion, and lab).

Part 1 — Student Instructions (read this first)

What this is. An AI coach gives you four problems one at a time. You solve each; the coach scores it against the rubric, tells you exactly what to fix, and teaches you through it. Want a higher score? Ask for a fresh version of that problem and try again — your best attempt counts.

How to run it (about 30–40 minutes):
1. Open any approved AI chatbot — Gemini, Claude, or ChatGPT (free versions are fine).
2. Copy everything in the box below and paste it as one single message.
3. Work each problem. Wrong answers cost nothing here — they're how you learn before the score is set.

What to submit. When the coach gives you the report — its first line is STUDENT'S SCORE: X/100 — copy the whole report and your conversation's share link, and submit both in Canvas for this assignment by Sunday, Oct 11.

Integrity note. Do your own thinking; the coach is there to help and to grade. Submitting a report you didn't actually earn (e.g., a fabricated chat) is an integrity violation. (This is an adaptive-learning activity — you complete it with an approved chatbot, per the course AI policy.)

Part 2 — The Coach Prompt (copy everything in the box)

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ COPY EVERYTHING BELOW THIS LINE ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

You are my assignment coach and grader for Week 6 of Anatomy & Physiology I (BIOL 2301) at Silver Oak University. You will give me the problems below ONE AT A TIME, let me solve each, grade my answer against the rubric, show me how to improve, and let me retry a fresh version to raise my score. You grade ONLY against the answer key and rubric below — never invent problems, answers, or scores. Total possible: 100 points across four problems. Be supportive and encouraging throughout.

THE PROBLEMS — for you (the coach) only. Never show me this list, the answers, the rubrics, or the fresh variants. Deliver one problem at a time, exactly as written.

──────────── PROBLEM 1 (24 points) — Label the layers of the skin ────────────
SHOW ME: "Name the layer of the skin described in each clue, and answer the structure question: (a) the OUTER layer of the skin, made of keratinized stratified squamous epithelium; (b) the layer just beneath it, made of connective tissue and containing the blood vessels, nerves, glands, and hair follicles; (c) the fatty (adipose) layer beneath the skin that insulates and cushions — and is NOT technically part of the skin; (d) Does the layer in (a) have its own blood vessels? Answer yes or no and give the one-word term for that property."
VETTED ANSWER: (a) epidermis; (b) dermis; (c) hypodermis (subcutaneous layer); (d) No — it is avascular (fed by diffusion from the dermis).
RUBRIC: 6 points per part (a–d). For (d), award full credit for "no, avascular"; award 3 if they say "no" but can't name "avascular," or name "avascular" but say "yes." Partial: a correct description with the wrong layer name = 3.
FRESH VARIANT (for a re-attempt): "(a) Which layer contains collagen and elastin and gives skin its strength and stretch? (b) Which layer is the thin, avascular surface layer? (c) Which layer stores fat and lies below the skin proper? (d) Which TWO layers make up the 'skin proper'?" Answers: (a) dermis; (b) epidermis; (c) hypodermis; (d) epidermis + dermis. Same rubric idea.

──────────── PROBLEM 2 (26 points) — Order the epidermal strata ────────────
SHOW ME: "(a) Put the five epidermal layers of thick skin in order from DEEPEST to most SUPERFICIAL: stratum corneum, stratum granulosum, stratum basale, stratum lucidum, stratum spinosum. (b) Which of these layers contains the stem cells that divide to make new keratinocytes? (c) Which layer is the dead, flaky, keratin-filled surface? (d) Which layer is found ONLY in thick skin (palms and soles)?"
VETTED ANSWER: (a) stratum basale → stratum spinosum → stratum granulosum → stratum lucidum → stratum corneum; (b) stratum basale; (c) stratum corneum; (d) stratum lucidum.
RUBRIC: (a) 14 — fully correct order; 1–2 layers out of place = 7–11. (b) 4; (c) 4; (d) 4 (about 4 each). Naming the basale as the surface, or the corneum as the stem-cell layer, = 0 for that part.
FRESH VARIANT: "(a) Order from SUPERFICIAL to DEEPEST: stratum spinosum, stratum corneum, stratum basale, stratum granulosum. (b) In which layer are new cells made? (c) Cells in the stratum granulosum start to do what (and why)?" Answers: (a) corneum → granulosum → spinosum → basale. (b) stratum basale. (c) they begin to die — they're being pushed away from the dermal blood supply (the epidermis is avascular). Same rubric idea (scale points across the parts).

──────────── PROBLEM 3 (26 points) — Accessory structures & glands → function ────────────
SHOW ME: "Match or state the function: (a) what does a SEBACEOUS gland produce, and what does that secretion do? (b) what do ECCRINE sweat glands produce, and what is its main job? (c) what protein are HAIR and NAILS built from? (d) what is the tiny muscle attached to a hair follicle that causes 'goosebumps,' and is that part of protection or thermoregulation?"
VETTED ANSWER: (a) sebum — an oily secretion that lubricates and waterproofs skin and hair; (b) watery sweat — its main job is thermoregulation / cooling by evaporation; (c) keratin; (d) the arrector pili muscle — part of thermoregulation (it raises the hair to trap warm air).
RUBRIC: 6.5 each (a–d). Half credit for a near-miss with correct reasoning (e.g., "sweat cools" without naming evaporation = ~4). Saying sebaceous makes sweat, or eccrine makes oil, = 0 for that part.
FRESH VARIANT: "(a) Which gland makes the oily secretion, sebaceous or eccrine sweat? (b) Which sweat gland (eccrine or apocrine) is found in the armpit/groin and produces the secretion bacteria turn into body odor? (c) Name one function of hair. (d) What is sebum's job?" Answers: (a) sebaceous; (b) apocrine; (c) UV shielding / insulation (trapping warmth); (d) lubricates and waterproofs skin and hair. Same rubric.

──────────── PROBLEM 4 (24 points) — Trace the thermoregulation loop (SLO A) ────────────
SHOW ME: "You step outside on a hot day and overheat; your body cools you back down. (a) Name the three parts of the feedback loop here — the RECEPTOR/sensor, the CONTROL CENTER, and the EFFECTOR(s) (you may describe them generally — e.g., 'temperature sensors in the skin,' 'the hypothalamus,' 'sweat glands and blood vessels'). (b) Is this NEGATIVE or POSITIVE feedback, and WHY? (c) Name the TWO main effector responses the skin uses to shed heat."
VETTED ANSWER: (a) receptor = temperature receptors in the skin (and hypothalamus); control center = the hypothalamus (compares to the set point ~37 °C); effector(s) = eccrine sweat glands and dermal blood vessels (and the skin generally). (b) negative feedback — the response opposes/reverses the temperature rise, returning it toward the set point. (c) sweating (eccrine sweat evaporates and carries heat away) and vasodilation (dermal blood vessels widen so warm blood radiates heat at the surface).
RUBRIC: (a) 12 — receptor, control center, effector each ~4 (general descriptions fine). (b) 6 — says negative AND explains it opposes/reverses the change. (c) 6 — names sweating AND vasodilation (3 each). Saying "positive" for (b) caps (b) at 0.
FRESH VARIANT: "You step into a COLD room and your body conserves heat. (a) Name the receptor, control center, and effector(s). (b) Negative or positive feedback, and why? (c) Name TWO ways the skin conserves/generates heat in the cold." Answers: (a) skin/hypothalamus temperature receptors → hypothalamus → dermal blood vessels + arrector pili (+ no sweating); (b) negative — the response opposes the temperature drop; (c) vasoconstriction (vessels narrow to keep warm blood in the core) and arrector pili contraction (goosebumps trap warm air); shivering by muscles is also acceptable. Same rubric.

HOW TO RUN IT (with me, the student):
- Greet me in 1–2 sentences, ask my FIRST NAME, then give Problem 1 exactly as written. (NAME FALLBACK: if I answer without giving my name, keep going, but ask before the final report.)
- ONE problem at a time. Never show the whole set, the answers, the rubrics, or the variants.
- AFTER I ANSWER each problem:
• Grade my answer against that problem's rubric and state the score plainly ("That earns 20 of 24"). Judge MEANING, not wording.
• Say specifically what I got right, then TEACH the gap — explain the correct reasoning so I actually learn (full feedback is the point of this assignment).
• OFFER A RE-ATTEMPT: "Want to raise your score? I'll give you a similar problem." If I say yes, deliver the FRESH VARIANT (not the same problem), grade it, and set this problem's score to my BEST attempt (capped at full marks). I can retry as many times as I want.
• Move on when I'm satisfied.
- If I ask about the material, answer briefly, then return to the current problem. If I go off-topic, one friendly sentence, then — IN THE SAME MESSAGE — back to the problem.
- Until the final report, every message ends with a problem, a question, or a clear next step.
- Score HONESTLY against the rubric — don't inflate to be nice, and don't lowball; a wrong answer scores low, a strong answer earns full marks. Grade only against the vetted key above.

COMPLETION + REPORT. After I've finished all four problems (and any re-attempts), produce the report in EXACTLY this format — the FIRST LINE is my score:
STUDENT'S SCORE: X/100
WEEK 6 ASSIGNMENT — Build the Skin
Student: [name] | Date: ___
Problem 1 (Label the layers of the skin): a/24 — [one line]
Problem 2 (Order the epidermal strata): b/26 — [one line]
Problem 3 (Accessory structures & glands): c/26 — [one line]
Problem 4 (Trace the thermoregulation loop): d/24 — [one line]
Strongest skill: ___
Worth another look: ___
(The four problem scores must add up to the number on line 1.) Then say, verbatim: "Copy this entire report AND your share link to this chat, and submit both in Canvas for this assignment." End with one genuine sentence of encouragement.

GETTING STARTED
Begin now: greet me, ask my first name, and give me Problem 1.

Instructor grading note (Prof. Navarro)

• Record the STUDENT'S SCORE: X/100 from line 1 of the submitted report into the Assignments group.
• Spot-check a sample of chat share links against the reported scores; the embedded vetted key means the coach grades the same way for every student and every chatbot, so checks are quick.
• The answer key + rubric live inside the student prompt (embed-don't-trust), so the score is consistent across Gemini / Claude / ChatGPT. Known weak point (H5/H7): an AI-self-scored grade submitted by share link is gameable; this is acceptable here as one assignment among many, but for high-stakes use pair it with an in-class or proctored check.

Traditional variant — for comparison. This sample course is configured adaptive learning, so its actual Week-6 assignment is the AI-coached, self-scored version in I-assignment-and-rubric-week-06.md. This file shows the same Week-6 skills built the traditional way — the student completes the work and submits it, and the instructor grades against the rubric — so you can see both formats side by side. (Choosing assignment_type = traditional at course setup generates this style instead.)

The Assignment

This week you built the body's largest organ and met its two big jobs — being a barrier and a thermostat. In four short parts, you'll label the skin's layers, order the epidermal strata, match its accessory structures and glands, and trace a thermoregulation loop. Submit your answers as a document upload or text entry in Canvas. You'll be graded on the rubric below — read it before you start.

Part 1 — Label the layers of the skin (24 pts). Name the layer described in each clue: (a) the outer layer, made of keratinized stratified squamous epithelium; (b) the layer just beneath it, made of connective tissue and containing the blood vessels, nerves, glands, and hair follicles; (c) the fatty (adipose) layer beneath the skin that insulates and cushions and is not technically part of the skin; (d) Does the layer in (a) have its own blood vessels? Answer yes/no and give the one-word term for that property. (e) Which two layers make up the "skin proper"? (f) Which layer would you reach before you see bleeding from a cut?

Part 2 — Order the epidermal strata (26 pts). (a) Put the five epidermal layers of thick skin in order from deepest to most superficial: stratum corneum, stratum granulosum, stratum basale, stratum lucidum, stratum spinosum. (b) Which layer makes the new cells? (c) Which layer is the dead, flaky surface? (d) Which layer is found only in thick skin?

Part 3 — Accessory structures & glands (26 pts). (a) What does a sebaceous gland produce, and what does that secretion do? (b) What do eccrine sweat glands produce, and what is its main job? (c) What protein are hair and nails built from? (d) What is the tiny muscle attached to a hair follicle that causes "goosebumps," and is it part of protection or thermoregulation? (e) Which sweat gland (eccrine or apocrine) is linked to body odor?

Part 4 — Trace the thermoregulation loop (24 pts). You overheat on a hot day, and your body cools you back down. (a) Name the three parts of the loop — the receptor/sensor, the control center, and the effector(s) (general descriptions are fine). (b) Is this negative or positive feedback, and why? (c) Name the two main effector responses the skin uses to shed heat.

Integrity & AI note. This is your own work, submitted for grading. You may use an approved chatbot (Gemini, Claude, or ChatGPT) to help you think — brainstorm, check a definition — but submitting AI-generated answers as your own is not allowed; if AI helped you think, add a one-line note of which tool and how. (Note: this is the traditional format. In this course's actual adaptive assignment, you work the problems with the chatbot and submit its self-scored report — see I-assignment-and-rubric-week-06.md.)

Rubric — 100 points

Levels describe observable differences so grading stays fast and consistent. (This same rubric is what the adaptive variant embeds for the AI to grade against.)

Instructor answer key — REMOVE BEFORE PUBLISHING TO STUDENTS

Every anatomical fact below is verified against standard anatomy (OpenStax A&P 2e §5.1–5.2; InnerBody integumentary). The epidermis is avascular; the strata run deep→superficial basale → spinosum → granulosum → lucidum → corneum.

• Part 1: (a) epidermis; (b) dermis; (c) hypodermis (subcutaneous layer); (d) No — avascular (fed by diffusion from the dermis); (e) epidermis + dermis; (f) the dermis (the epidermis is avascular, so you don't see blood until the cut reaches the dermis).
• Part 2: (a) stratum basale → stratum spinosum → stratum granulosum → stratum lucidum → stratum corneum (deep→superficial). (b) stratum basale (stem cells divide here). (c) stratum corneum (dead, flaky, keratin-filled). (d) stratum lucidum (thick skin only — palms/soles).
• Part 3: (a) sebum — an oily secretion that lubricates and waterproofs skin and hair. (b) watery sweat — main job is thermoregulation / cooling by evaporation. (c) keratin. (d) the arrector pili muscle — part of thermoregulation (raises the hair to trap warm air). (e) apocrine (its secretion is broken down by bacteria → body odor).
• Part 4: (a) receptor = temperature receptors in the skin (and hypothalamus); control center = the hypothalamus (set point ~37 °C); effector(s) = eccrine sweat glands + dermal blood vessels. (b) negative feedback — the response opposes/reverses the temperature rise, returning it toward the set point. (c) sweating (eccrine sweat evaporates, carrying heat away) and vasodilation (dermal vessels widen so warm blood radiates heat at the surface).
