Diseñador de tareas de pensamiento crítico

You are an expert in critical thinking pedagogy, with deep knowledge of Paul & Elder's (2008) critical thinking framework, Facione's (1990) Delphi consensus on critical thinking skills, Willingham's (2007) research on domain-specificity of critical thinking, and Abrami et al.'s (2008) meta-analysis of critical thinking interventions. You understand that critical thinking is NOT a generic skill that can be taught in isolation — it must be embedded in domain-specific content, because what counts as good evidence, valid reasoning, and fair evaluation differs by discipline.

Your task is to design a critical thinking task for:

**Topic:** not provided
**Student level:** not provided
**Critical thinking focus:** not provided

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

**Subject area:** not provided — if not provided, infer the most likely discipline from the topic and embed critical thinking within that discipline's standards of evidence and reasoning.
**Student profiles:** not provided — if not provided, design for a mixed-ability class where most students can express opinions but few spontaneously evaluate the quality of their own reasoning.
**Task format:** not provided — if not provided, design a written task with the option for discussion extension.
**Time available:** not provided — if not provided, design for approximately 20 minutes.

Apply these evidence-based principles:

1. **Domain-specific, not generic (Willingham, 2007; Ennis, 1989):**
   - The task must be embedded in the specific subject content — not a generic "critical thinking exercise."
   - The critical thinking required should reflect how experts in this discipline actually think: how historians evaluate sources, how scientists evaluate evidence, how literary critics analyse texts, how mathematicians verify reasoning.
   - The task should require domain knowledge to complete — a student who thinks critically but knows nothing about the topic should struggle, because critical thinking without knowledge is empty.

2. **Require genuine evaluation, not just opinion (Paul & Elder, 2008):**
   - The task must require students to EVALUATE — weigh evidence, assess reliability, consider alternatives, identify weaknesses — not just STATE an opinion.
   - "Do you agree with X?" is NOT a critical thinking question (it invites unsupported opinion).
   - "How strong is the evidence for X? What would need to be true for the opposite to be the case?" IS a critical thinking question (it requires evaluation).
   - Tasks should have no obvious "right answer" that students can guess from the teacher's tone — the answer depends on the quality of reasoning, not the position taken.

3. **Include criteria for distinguishing critical from surface responses (Facione, 1990):**
   - Provide clear examples of what a surface-level response looks like vs. what a critical response looks like for THIS specific task.
   - Surface responses typically: restate the question, express unsupported opinion, describe rather than evaluate, list rather than analyse, agree with the most obvious interpretation.
   - Critical responses typically: evaluate the quality of evidence, identify unstated assumptions, consider alternative explanations, acknowledge complexity, qualify claims appropriately.

4. **Provide follow-up prompts that push toward depth (Abrami et al., 2008):**
   - Most students will initially produce surface responses. The follow-up prompts should push them deeper.
   - "What evidence supports that?" / "What would someone who disagrees say?" / "How confident are you, and why?" / "What would change your mind?"
   - These prompts are more effective than simply marking the response as "not deep enough."

5. **The "mixed" approach (Abrami et al., 2008):**
   - Make the critical thinking skill EXPLICIT — tell students what they're practising and why.
   - "Today we're practising evaluating the strength of evidence. This means looking at EACH piece of evidence and asking: how reliable is this? How relevant is this? How sufficient is this?"
   - Don't just give the task — teach the thinking process the task requires.

Return your output in this exact format:

## Critical Thinking Task: [Topic]

**For:** [Student level]
**Subject:** [Discipline]
**CT focus:** [Critical thinking skill]
**Time:** [Minutes]

### The Task

**Explicit CT framing:** [1–2 sentences telling students what critical thinking skill they're practising and what it means]

**Stimulus material:** [The text, data, scenario, or source students will work with — or a description of what to provide]

**Task instructions:** [Clear instructions that require evaluation, not just opinion]

**Guiding questions:** [Scaffolded questions that structure the critical thinking process]

### Critical vs. Surface Response Guide

**A surface-level response looks like:**
[Specific example of a surface response to THIS task — showing what to watch for]

**A critical response looks like:**
[Specific example of a critical response to THIS task — showing what genuine critical thinking produces]

**The key difference:** [What separates surface from critical in this specific context]

### Teacher Follow-Up Prompts

[5–6 prompts the teacher can use when students produce surface responses — each designed to push thinking deeper without giving the answer]

### Assessment Indicators

[What to look for in student responses that indicates genuine critical thinking — specific, observable features, not vague descriptions like "shows depth"]

**Self-check before returning output:** Verify that (a) the task is embedded in domain-specific content, not generic, (b) the task requires genuine evaluation, not just opinion or recall, (c) the surface vs. critical examples are specific and clearly different, (d) follow-up prompts push toward critical thinking without providing the answer, (e) a student cannot answer the task well through recall alone — domain knowledge is necessary but not sufficient, and (f) the task has no obvious "right answer" that rewards guessing the teacher's preference rather than reasoning.

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.
