Description¶

Prompted Source Evaluation pairs strategy instruction with written prompts that walk students through evaluating sources along defined dimensions: relevance and accuracy (quality of content), reliability and perspective (the author's agenda and affiliations), and corroboration (cross-checking claims across multiple sources). Prompts ask students to look for evidence that both supports and refutes key claims, weigh new ideas against prior beliefs, and justify their judgments in writing. The prompts function as temporary scaffolds that make expert evaluation routines explicit until students internalize them.

Design Implications¶

Explicit prompting converts an otherwise tacit expert practice into a learnable procedure, and structured civic online reasoning instruction of this kind measurably improves students' evaluation of sources Civic online reasoning instruction improves students' ability to evaluate online sources. [+S]. The written response requirement adds Generation-like benefits: students must commit to a judgment rather than passively skim. Prompts should be faded over time so that prompted evaluation becomes self-initiated evaluation Contingent scaffolding improves learning outcomes. [+M].

Context¶

Requirements¶

• A written prompt set or planning guide organized around evaluation dimensions (accuracy, relevance, reliability, perspective, corroboration)
• Authentic source examples, ideally including sources of deliberately mixed quality
• A framework for cross-checking claims across sources (see Three-Source Rule)
• Time for students to write and discuss their evaluations (Individual Reflection, Class Discussion)

Constraints¶

• Prompt-driven evaluation is effortful; without fading, students may remain prompt-dependent and fail to transfer the routine to unstructured tasks [-M]
• Students with weak background knowledge may complete prompts superficially, rating sources plausibly but without genuine content judgment [~M]
• Lateral reading techniques (leaving a source to investigate its claims elsewhere) require internet access and search skills; print-only implementations lose the most effective evaluation moves [~S]
• Deeply held prior beliefs can bias how students apply the prompts — they may scrutinize disagreeing sources more harshly than agreeing ones [~M]

Implementation Variability¶

• Checklist prompts — short yes/no heuristics (e.g., Who is the author? What is the evidence?); fast but shallower
• Question-set prompts — open questions requiring written justification; deeper but slower
• Lateral-reading prompts — direct students to open new tabs and investigate the source's claims, funding, and reputation before judging it
• Cross-checking protocols — structured comparison of two or three sources on the same claim, weighing disagreements

Target Learners¶

• Adolescents and undergraduates encountering unvetted web sources for research or civic tasks Civic online reasoning instruction improves students' ability to evaluate online sources. [+S]
• Students who tend to judge credibility by surface features (design, domain suffix, length) rather than content and provenance
• Less necessary for learners already fluent in disciplinary evaluation norms, for whom prompts may be redundant [~W]

Target Learning Goals¶

• Critical evaluation: judging accuracy, reliability, and perspective of information sources
• Evidence-based reasoning: weighing claims for and against prior beliefs
• Disciplinary literacy: applying field-specific standards for what counts as a credible source Disciplinary literacy instruction improves comprehension of discipline-specific texts. [+M]

Instructions¶

1. Introduce the evaluation dimensions (accuracy, relevance, reliability, perspective) with a worked example of an expert evaluating a source aloud (Think-Aloud).
2. Distribute the written prompt guide and a target source; students respond to each prompt in writing (Annotating).
3. Have students cross-check key claims against at least one additional source (Three-Source Rule).
4. Debrief in Class Discussion, surfacing disagreements about credibility and their grounds.
5. Fade the prompts across successive tasks, moving from full guides to a single self-generated question (Fading, Practice).

Related Strategies¶

• A Finder's Guide to Facts — a companion framework for locating and verifying factual claims
• Three-Source Rule — the cross-checking protocol that operationalizes corroboration
• Annotating — the written-response mechanism through which prompts act

Examples¶

• Stanford History Education Group — Civic Online Reasoning curriculum — Free lessons and assessments in which students evaluate live web sources using prompted questions about source, evidence, and corroboration; the research program behind this curriculum showed large gains in evaluation skill [+S].
• News Literacy Project — Checkology — Interactive lessons prompting middle and high school students to evaluate news sources for credibility, bias, and sourcing.
• History classroom implementation — Students use a planning guide to evaluate a primary source: prompts ask who created it, for what audience, what it omits, and how a second source corroborates or contradicts it.
