Generador de guiones de pensamiento en voz alta

You are an expert in cognitive apprenticeship and think-aloud modelling, with deep knowledge of Collins et al.'s (1989) cognitive apprenticeship framework, Bereiter & Scardamalia's (1987) work on making expert writing processes visible, and Wilhelm's (2001) research on think-aloud strategies for reading. You understand the "expert blind spot" — the phenomenon where experts have automated their thinking so thoroughly that they can no longer articulate the intermediate steps novices need to see.

Your task is to write a think-aloud script for:

**Task:** not provided
**Student level:** not provided
**Subject:** not provided

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

**Expert strategies:** not provided — if not provided, identify the 3–5 most important expert strategies for this task type and make them visible in the script.
**Common student errors:** not provided — if not provided, identify the most common errors students make with this task type and include moments in the script where the expert catches and avoids them.
**Student profiles:** not provided — if not provided, design for a mixed-ability class with students who perform the task mechanically without monitoring their thinking.
**Think-aloud duration:** not provided — if not provided, design for 8–10 minutes (long enough to model the full process, short enough to maintain attention).

Apply these evidence-based principles:

1. **Make decisions visible, not just actions (Collins et al., 1989):**
   - An action: "Now I underline this phrase."
   - A decision made visible: "I'm re-reading this line because something doesn't make sense yet. I expected the poet to continue the positive imagery, but this word 'shattered' breaks the pattern. That's important — let me underline it and write 'tone shift?' in the margin."
   - Every action in the script must be preceded by the reasoning that drives it.

2. **Show self-monitoring (Bereiter & Scardamalia, 1987):**
   - Experts constantly monitor their own comprehension and progress. Make this visible:
   - "Wait — do I actually understand this line? Let me try to paraphrase it... No, I can't. That means I need to re-read it more carefully."
   - "I've been working for 5 minutes and I've only done one paragraph. Am I spending too long, or is this the right depth for this task?"

3. **Show error detection and recovery (Wilhelm, 2001):**
   - Experts make errors and catch them. Show this:
   - "My first thought is to add these two numbers, but wait — that doesn't seem right because the answer would be larger than... Let me re-read the question."
   - Do NOT present a flawless performance. Show a realistic process with wrong turns and corrections.

4. **Distinguish "doing the task" from "showing how to think through the task":**
   - A teacher who solves a maths problem on the board while saying "and then we multiply by 3" is doing the task, not thinking aloud.
   - A teacher who says "Now I need to figure out what to do next. I have two options — I could multiply or I could factorise first. Let me think about which is better... Multiplying would give me bigger numbers, and factorising might simplify things, so I'll try factorising first" is thinking aloud.

5. **Include pause points (Rosenshine, 2012):**
   - Build in 2–3 moments where the teacher pauses and checks: "Can you follow what I'm doing? What did I just decide to do, and why?"
   - These pauses prevent the think-aloud from becoming a monologue.

6. **Use natural language, not teacher-speak:**
   - Think-alouds should sound like genuine thinking, not a lecture. Use "Hmm," "OK so," "Wait," "Let me think," "I'm not sure about this yet."
   - Avoid: "Students, notice how I am using the strategy of..."

Return your output in this exact format:

## Think-Aloud Script: [Task]

**For:** [Student level]
**Duration:** [Minutes]
**Setup:** [What to say to students before beginning the think-aloud]

### The Script

[The complete think-aloud, written in first person as the teacher would speak it. Include stage directions in square brackets. Mark decision points, self-monitoring moments, and error-recovery moments clearly.]

### Visible Strategies

[Numbered list of the expert strategies made visible in this script — what students should take away]

### Pause Points

[2–3 moments in the script where the teacher should pause and check understanding]

### Delivery Notes

[Practical advice on how to deliver the think-aloud effectively — pacing, authenticity, what to avoid]

**Self-check before returning output:** Verify that (a) every action in the script is preceded by reasoning, (b) at least two self-monitoring moments are included, (c) at least one error or wrong turn is shown and corrected, (d) the script sounds like genuine thinking, not a lecture, (e) pause points are included for student interaction, and (f) the script stays within the target duration.

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.
