Scoring Two Interpretations of a Metaphor Poem
Mr. Costa's Portuguese III class is studying how metaphor builds meaning. He gives students this four-line poem, written for the lesson:
Minha avó bordava o mar com linha azul e paciência; cada onda que ela fazia era um pedaço de ausência.
Students write a one-paragraph interpretation, scored on a 4-point district rubric with four criteria: literal comprehension, interpretation of figurative language, use of textual evidence, and control of Portuguese. Two samples:
Ana: "A avó da poeta bordava o mar com linha azul. Ela tinha muita paciência porque bordar demora. O poema fala do mar."
Beto: "A avó transforma o mar em bordado porque a ausência de alguém pesa; cada onda é um pedaço dessa falta, então o bordado é uma forma de lembrar."
Mr. Costa must score both on the same rubric, and the department requires scores to be defensible if a parent appeals. He notices that Ana's paragraph is nearly error-free and that Beto's has two agreement slips.
1. Score both paragraphs criterion by criterion and explain each score. Why must Ana's fluency not raise her interpretation score, and why must Beto's slips not sink his?

Score each criterion independently before totaling anything.
Ana - literal comprehension: 3. Accurate on the surface (grandmother, blue thread, patience), but she reduces "bordava o mar" to a literal statement and never mentions ausência. Figurative interpretation: 1. She retells and stops; "O poema fala do mar" is a topic label, not an interpretation. Textual evidence: 1. Nothing from the poem is used to support a claim. Control of Portuguese: 4. Nearly error-free, though the sentences are short and syntactically simple. Total: 9/16.
Beto - literal comprehension: 2. He interprets immediately and never grounds the surface scene, so a reader could not reconstruct what the poem literally describes from his paragraph. Figurative interpretation: 4. He identifies the tenor and vehicle (bordado as memory; onda as a piece of absence) and explains how the metaphor produces meaning. Evidence: 3. He builds on the poem's own words, though he does not quote the literal details. Control: 3. Two agreement slips alongside subordinate clauses and risk-taking syntax. Total: 12/16.
The two errors Mr. Costa must not make are symmetrical. If Ana's clean Portuguese lifts her interpretation score, the rubric has silently weighted grammar twice and has rewarded a student for avoiding difficulty. If Beto's agreement slips cap his interpretation, the same double-weighting occurs in the other direction. The criterion structure exists precisely to prevent this; the total is computed last.
2. What is the next instructional move for each student, and how does Mr. Costa keep the two moves from becoming the same lesson?
Read the worked answer
Ana needs a bridge into figurative reading, with a text simple enough that comprehension is not the obstacle. Move: ask three questions in sequence - "O mar cabe numa agulha? Então o que a avó está fazendo quando borda o mar? Se cada onda é 'um pedaço de ausência', de quem ou do que ela sente falta?" Then give a sentence frame: "O bordado representa ___ porque o poema diz ___." She should produce one such sentence before writing a full paragraph. Her strength - clean, controlled prose - becomes the vehicle for the new skill rather than the thing being graded.
Beto needs grounding and precision. Move: before any interpretation, write one sentence that a reader who has never seen the poem could use to picture the scene. Then require an exact quotation for each interpretive claim, not a paraphrase. His two agreement slips should be handled as a targeted, low-stakes correction (identify them himself; check the noun-adjective pairs) rather than a general grammar lesson, because his writing is developmentally ahead of his control and over-correcting will push him toward short safe sentences.
Keeping the moves distinct matters: Ana's task is interpretive risk, Beto's is evidentiary discipline. Assigning both the same worksheet would give Ana more literal practice she does not need and Beto more interpretation he already does well.
3. How should the rubric and the classroom record be set up so the scores survive a parental appeal?

Three safeguards:
Anchor the rubric in student work. The department should keep one annotated sample per score level for each criterion and use those anchors during scoring. An appeal is answered with "here is a 4 in interpretation and here is why this paragraph matches it," not with teacher intuition.
State the ceiling rules in writing. The rubric should say explicitly that a paragraph that only retells the poem cannot score above 1 on interpretation, and that a paragraph with no textual support cannot score above 2 on evidence. Ana's 1 and Beto's 3 then follow from a published rule rather than from the scorer's mood.
Score language once. Language control is its own criterion; Mr. Costa should note in the record that it is not applied a second time inside the interpretation criterion, and should keep the two sections visually separate on the scoring sheet.
Additionally, the interpretation must have been taught, not merely tested: the class discussion of the poem should be documented (board notes, guiding questions) so that a parent can see the student had access to the reading the rubric rewards. A rubric that demands an insight students were never helped to reach is vulnerable on grounds other than accuracy.
