Two Teachers, Two Rubrics, One Botanical Plate
A middle school runs a six-week “Field Notes” project: 7th graders in four classes of 27 study a local tree species in science and produce a botanical plate in art. The science teacher grades identification accuracy - leaf arrangement, venation, scale - on a 20-point checklist. The art teacher grades composition and craft on a 20-point rubric that rewards “expressive line quality.” Last year the strongest science scores came from plates drawn tiny in one corner, cramped, with labels crowding the specimen; the best compositions had confident, expressive, botanically wrong leaves. Two students were rated proficient in art and below basic in science on the same plate, and parents asked which grade “counts.” The project restarts in ten days.
1. Diagnose the structural problem with the assessment design, and identify any criterion the two rubrics genuinely share.

The two rubrics reward opposite behaviors, and neither teacher can see the tradeoff students are making. A student who draws small and cramped is minimizing risk and maximizing labelable detail - rewarded in science, penalized in art. A student who draws large and loose is buying visual confidence at the cost of diagnostic information - rewarded in art, penalized in science. Because the rubrics never reference each other, students experience the project as a choice between two grades rather than one artifact, and the “which counts” question from parents is a fair response to a real design flaw.
The shared criterion already exists and was never named: legibility of the diagnostic features. A botanical plate is an argument about what matters on a specimen. Scale, label placement, an inset detail, and white space are compositional devices with informational jobs. That sentence is the hinge the whole redesign needs, and it belongs in both classrooms before the first pencil moves.
2. Propose a single assessment design and a workable workflow for two teachers and 108 students.

Use one plate, one shared three-row rubric, two grading lenses:
- Scientific accuracy of diagnostic features - graded by the science teacher against the checklist.
- Visual hierarchy and legibility - graded by the art teacher, with the criterion phrased as “can a viewer locate the diagnostic features quickly?”
- Craft and annotation - graded jointly, or by whoever sees the work second.
Workflow: a required layout thumbnail approved before the final (catches the corner-drawing problem early), one revision cycle after feedback, and a single due date so neither class is graded on a draft. Report the two course grades separately, with a shared note explaining that both describe the same artifact.
Revise the art rubric wording as well: replace “expressive line quality” with “line quality supports the specimen's description.” That single change removes the incentive to be confidently wrong, and it makes the art grade defensible to a parent who is looking at a plate with the wrong leaf arrangement.
3. How should the teachers answer the parents' question about which grade counts, and how should they handle the student caught between the two grades?
Read the worked answer
Answer directly: both count, in their own courses, and they measure related but distinct things about one piece of work. Then show it - a short paragraph in the project letter naming the shared idea (a plate argues about what matters), so the parent is not asked to take the coherence on faith.
For a student rated proficient in art and below basic in science, the conversation should not be a negotiation between teachers over who relents. Pull the plate out and point to the specific diagnostic features that are missing or wrong, then ask what compositional choice caused it - usually scale or crowding. The student should leave with one revision task, not a verdict.
One risk to watch: joint projects often drift toward the art grade becoming a reward for decorating the science. The hierarchy criterion is what prevents that, because it is judged by whether information can be found, not by whether the drawing is attractive.
