Week 11 — Assignment (Adaptive Learning) · "Read the Muscle"

Course: Anatomy & Physiology I (BIOL 2301 + BIOL 2101) · Silver Oak University (fictional sample) · Prof. Navarro
Objective assessed: Objective 5 (origin/insertion; muscle teamwork; lever classes & mechanics; muscle naming & the major muscles → actions) · SLO A (relate structure to function) · SLO B (use muscular terminology; light quantitative — the lever equation)
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 11 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, Nov 15.

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 11 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) — Origin, insertion, agonist & antagonist ────────────
SHOW ME: "Answer each: (a) Of a muscle's two attachments, which one is on the bone that STAYS FIXED — the origin or the insertion? (b) Which attachment MOVES during contraction? (c) When the biceps brachii flexes the forearm (it is the agonist), which muscle is the ANTAGONIST? (d) Muscles create movement by pulling or by pushing — which?"
VETTED ANSWER: (a) the origin (fixed bone); (b) the insertion (the bone that moves, pulled in toward the origin); (c) the triceps brachii (it extends the forearm); (d) by pulling (muscles only shorten/pull, never push).
RUBRIC: 6 points per item (a–d). Partial: a near-miss with correct reasoning (e.g., "the triceps, which straightens the arm") earns full; naming a synergist like the brachialis for (c) = 3.
FRESH VARIANT (for a re-attempt): "(a) When you straighten your knee, the quadriceps is the agonist — what is the antagonist? (b) Is the origin or the insertion the part that moves? (c) The pectoralis major — name one of its actions on the arm. (d) Can a single muscle both bend and straighten the same joint by itself? Why or why not?" Answers: (a) the hamstrings; (b) the insertion; (c) flexes/adducts the arm; (d) no — muscles only pull, so a second (antagonist) muscle is needed to reverse the movement. Same rubric.

──────────── PROBLEM 2 (26 points) — Match muscles to their actions ────────────
SHOW ME: "Give the main action of each muscle: (a) deltoid; (b) gastrocnemius; (c) hamstrings; (d) triceps brachii; (e) gluteus maximus."
VETTED ANSWER: (a) deltoid — abducts the arm (raises it away from the midline at the shoulder); (b) gastrocnemius — plantarflexes the foot (points the toes); (c) hamstrings — flex the knee (flex the leg); (d) triceps brachii — extends the forearm at the elbow; (e) gluteus maximus — extends the hip/thigh.
RUBRIC: about 5 points each (a–e); 26 total (round generously). Judge meaning — "raises the arm out to the side" = abduction = full credit. A reversed action (e.g., "hamstrings extend the knee") = 0 for that item.
FRESH VARIANT: "Give the main action of each: (a) biceps brachii; (b) quadriceps femoris; (c) rectus abdominis; (d) masseter; (e) pectoralis major." Answers: (a) flexes the forearm; (b) extends the knee; (c) flexes the trunk; (d) closes the jaw (chewing); (e) flexes/adducts the arm. Same rubric.

──────────── PROBLEM 3 (26 points) — Lever classes + a lever calculation ────────────
SHOW ME: "(a) Name the three lever classes by what sits in the MIDDLE (fulcrum, load, or effort), and say which class is MOST COMMON in the body. (b) In a biceps curl, what plays the fulcrum, what is the effort, and what is the load? (c) LEVER MATH — use effort x effort-arm = load x load-arm: a 60 N load sits 36 cm from the elbow (the fulcrum), and the biceps inserts 4 cm from the elbow. How much effort must the biceps produce?"
VETTED ANSWER: (a) first-class = fulcrum in the middle; second-class = load in the middle; third-class = effort in the middle; third-class is by far the most common in the body. (b) the elbow joint = fulcrum; the biceps = effort; the weight in the hand = load (the forearm is the lever). (c) effort x 4 = 60 x 36 = 2160, so effort = 2160 / 4 = 540 N.
RUBRIC: (a) 9 — three classes correctly tied to the middle element + third-class named as most common (3 each, scale). (b) 7 — fulcrum/effort/load correctly assigned. (c) 10 — correct setup AND correct answer of 540 N (setup with arithmetic slip = 5–7). The numbers are pre-verified: 60 x 36 = 2160; 2160 / 4 = 540.
FRESH VARIANT: "(a) Which lever class is the body's most common, and where is the effort in it? (b) Standing on tiptoe is which lever class, and what's in the middle? (c) LEVER MATH: a 50 N load sits 40 cm from a joint and the muscle inserts 5 cm from the joint — find the effort." Answers: (a) third-class; effort between the fulcrum and the load. (b) second-class; the load is in the middle. (c) 50 x 40 = 2000; 2000 / 5 = 400 N. Same rubric. (All pre-verified.)

──────────── PROBLEM 4 (24 points) — Muscle naming & region ────────────
SHOW ME: "Muscle names are built from clues (location, shape, size, action, number of origins). For each, say what the name tells you: (a) what does 'biceps' tell you about the number of origins/heads? (b) what does 'deltoid' tell you about shape? (c) what does 'gluteus maximus' tell you compared to gluteus medius and minimus? (d) what does 'rectus abdominis' tell you about location and fiber direction?"
VETTED ANSWER: (a) biceps = two heads/origins (tri = three, quad = four); (b) deltoid = triangular, shaped like the Greek letter delta; (c) gluteus maximus = the largest of the three buttock muscles (medius = medium, minimus = smallest), all in the buttock/hip; (d) rectus abdominis = the straight (rectus) muscle of the abdomen — located in the abdominal wall with fibers running straight up and down.
RUBRIC: 6 each (a–d). Judge meaning — "delta = triangle" = full credit for (b). Partial for a correct-but-incomplete clue (e.g., "biceps is in the arm" without "two heads") = 3.
FRESH VARIANT: "(a) What does 'triceps' tell you about number of origins? (b) What does the 'maximus/medius/minimus' set tell you? (c) What does an '-or' action name like 'flexor' or 'extensor' tell you a muscle does? (d) What region is the 'brachialis' in (hint: brachium)?" Answers: (a) three heads/origins; (b) relative size — largest/medium/smallest; (c) its action — a flexor flexes, an extensor extends; (d) the arm (brachium = arm). 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.
- For the lever math in Problem 3, check my arithmetic against the pre-verified key (540 N; the variant is 400 N). If I set it up right but slip on the arithmetic, give partial credit and show the clean calculation.
- 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 11 ASSIGNMENT — Read the Muscle
Student: [name] | Date: ___
Problem 1 (Origin/insertion & agonist/antagonist): a/24 — [one line]

Problem 3 (Lever classes + lever math): c/26 — [one line]
Problem 4 (Muscle naming & region): 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

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 lever numbers (540 N; variant 400 N) are pre-computed and verified, so the math grades consistently.
• 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-11 assignment is the AI-coached, self-scored version in I-assignment-and-rubric-week-11.md. This file shows the same Week-11 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

The muscular system rewards two skills: predicting what a muscle does from where it attaches, and reasoning about the lever it works through. In four short parts, you'll sort origin from insertion and agonist from antagonist, match the major muscles to their actions, classify levers (with one calculation), and decode muscle names. 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 — Origin/insertion & agonist/antagonist (24 pts). Answer each: (a) Of a muscle's two attachments, which is on the bone that stays fixed — the origin or the insertion? (b) Which attachment moves during contraction? (c) When the biceps brachii flexes the forearm (it is the agonist), which muscle is the antagonist? (d) Do muscles create movement by pulling or pushing? (e) When you straighten your knee, the quadriceps is the agonist — what is the antagonist? (f) Can one muscle, by itself, both bend and straighten the same joint? Why or why not?

Part 2 — Match muscles to their actions (26 pts). Give the main action of each muscle: (a) deltoid; (b) gastrocnemius; (c) hamstrings; (d) triceps brachii; (e) gluteus maximus; (f) biceps brachii.

Part 3 — Lever classes + a lever calculation (26 pts). (a) Name the three lever classes by what sits in the middle (fulcrum, load, or effort), and say which class is most common in the body. (b) In a biceps curl, what plays the fulcrum, what is the effort, and what is the load? (c) Lever math — using effort × effort-arm = load × load-arm: a 60 N load sits 36 cm from the elbow (the fulcrum), and the biceps inserts 4 cm from the elbow. How much effort must the biceps produce? Show your setup.

Part 4 — Muscle naming & region (24 pts). For each name, say what the clue tells you: (a) what does "biceps" tell you about the number of origins/heads? (b) what does "deltoid" tell you about shape? (c) what does "gluteus maximus" tell you compared to gluteus medius and minimus? (d) what does "rectus abdominis" tell you about location and fiber direction?

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-11.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 muscle action below is verified against standard anatomy (OpenStax A&P §11.1–11.2; InnerBody muscular). The lever arithmetic is pre-computed and Python-verified.

• Part 1: (a) the origin (fixed/stationary bone); (b) the insertion (the bone that moves, pulled in toward the origin); (c) the triceps brachii (extends the forearm); (d) by pulling (muscles only shorten/pull, never push); (e) the hamstrings (they flex the knee); (f) no — a muscle only pulls, so reversing a movement requires a second, antagonist muscle pulling the opposite way.
• Part 2: (a) deltoid → abducts the arm (raises it away from the midline at the shoulder); (b) gastrocnemius → plantarflexes the foot (points the toes); (c) hamstrings → flex the knee; (d) triceps brachii → extends the forearm at the elbow; (e) gluteus maximus → extends the hip/thigh; (f) biceps brachii → flexes the forearm at the elbow.
• Part 3: (a) first-class = fulcrum in the middle; second-class = load in the middle; third-class = effort in the middle; third-class is by far the most common in the body. (b) the elbow joint = fulcrum; the biceps = effort; the weight in the hand = load (the forearm is the lever). (c) effort × 4 = 60 × 36 = 2160, so effort = 2160 ÷ 4 = 540 N. (Pre-verified: 60 × 36 = 2160; 2160 ÷ 4 = 540.)
• Part 4: (a) "biceps" = two heads/origins (tri = three, quad = four); (b) "deltoid" = triangular, like the Greek letter delta; (c) "gluteus maximus" = the largest of the three buttock muscles (medius = medium, minimus = smallest); (d) "rectus abdominis" = the straight (rectus) muscle of the abdomen — in the abdominal wall, fibers running straight up and down.
