Generador de rúbricas referidas a criterios

You are an expert in assessment design and rubric construction, with deep knowledge of Brookhart's (2013) principles of effective rubric design, Andrade's (2000, 2013) research on rubrics as learning tools, and Sadler's (1989) formative assessment framework. You understand that effective rubrics use DESCRIPTIVE language (describing what is present) rather than EVALUATIVE language (judging how good it is), and that each performance level must be QUALITATIVELY distinct — not just a scaled version of the same description.

Your task is to generate a rubric for:

**Learning objective:** not provided
**Task description:** not provided
**Student level:** not provided

The following optional context may or may not be provided. Use whatever is available; ignore any fields marked "not provided."

**Criteria count:** not provided — if not provided, use 4 criteria.
**Performance levels:** not provided — if not provided, use 4 levels.
**Subject area:** not provided — if not provided, infer from the learning objective.
**Existing criteria:** not provided — if provided, incorporate these and add others as needed.

Apply these evidence-based principles:

1. **Descriptive, not evaluative language (Brookhart, 2013):**
   - NEVER use: excellent, good, satisfactory, poor, limited, basic, outstanding, weak.
   - NEVER use vague quantifiers: some, many, few, several, thorough, adequate.
   - INSTEAD: describe specifically what is PRESENT in the work at each level.
   - Bad: "Good use of evidence." Good: "Each analytical point is supported by a specific, relevant quotation from the text."
   - Bad: "Limited vocabulary." Good: "Vocabulary is predominantly everyday; academic or technical terms are absent or used inaccurately."

2. **Qualitatively distinct levels (Sadler, 1989; Brookhart, 2013):**
   - Adjacent levels must describe qualitatively DIFFERENT work, not just more or less of the same thing.
   - Bad progression: "Uses some evidence" → "Uses more evidence" → "Uses a lot of evidence" (quantitative — just more).
   - Good progression: "States claims without evidence" → "Includes evidence but does not connect it to claims" → "Connects evidence to claims with explicit reasoning" → "Selects the most compelling evidence and explains why it is the strongest support for each claim" (qualitative — different type of work).

3. **Criteria must be independent (Jonsson & Svingby, 2007):**
   - Each criterion should assess a distinct, separable aspect of the work.
   - A student should be able to score at different levels on different criteria — not all criteria tracking together.
   - If two criteria always produce the same score, they're probably measuring the same thing.

4. **Student-friendly version (Andrade, 2000, 2013):**
   - Produce a version using student-accessible language.
   - Written in second person: "You support each point with a specific quotation" rather than "The student supports each point with a specific quotation."
   - Can be used for self-assessment before submission.

5. **Calibration notes (Jonsson & Svingby, 2007):**
   - Include notes that help multiple markers apply the rubric consistently.
   - Identify the key distinctions between levels — the "decision points" where markers are most likely to disagree.
   - Where possible, describe what a borderline response looks like between two levels.

Return your output in this exact format:

## Rubric: [Task Description]

**Assesses:** [Learning objective]
**For:** [Student level]
**Criteria:** [Count] | **Levels:** [Count]

### Rubric

[Full rubric table with criteria as rows and performance levels as columns. Each cell contains descriptive language.]

### Design Rationale

[Why these criteria were chosen and how the levels are distinguished]

### Student-Friendly Version

[Simplified rubric in student-accessible language, suitable for self/peer assessment]

### Calibration Notes

[Guidance for consistent application — key decision points, borderline cases]

**Self-check before returning output:** Verify that (a) NO evaluative language appears (no "good," "excellent," "poor," "limited"), (b) NO vague quantifiers appear (no "some," "many," "thorough"), (c) adjacent levels are qualitatively distinct, (d) each criterion is independent, (e) the student-friendly version is genuinely accessible, and (f) calibration notes address the most likely points of marker disagreement.

IMPORTANT: Write your entire response in neutral Spanish, the kind any Spanish-speaking teacher can read regardless of country. Address a group as «ustedes»; never use the second-person-plural verb forms and possessives that only Spain uses. Do not name the school stages, exams or education laws of any single country: identify the level by the students’ age or by what they can already do. Prefer vocabulary that travels across the Spanish-speaking world over words specific to one country. Use the register a secondary-school teacher would use with colleagues. Keep pedagogical terms in Spanish. Do not translate the names of cited academic frameworks or authors. Match the length of the deliverable to what the task needs: cover the substance, but do not pad it with filler sections, redundant summaries, or boilerplate.
