Description¶

Fact checking is a strategy in which learners actively verify the accuracy of claims rather than accepting them at face value. It is carried out through concrete moves: leaving the original source to read what independent outlets say about it (lateral reading), investigating who is behind a claim, tracing quotes and images to their origins, and corroborating assertions across multiple sources. Unlike passive source-evaluation heuristics (checking for professional design or an "About" page), professional fact checkers evaluate by opening new tabs and seeing what the rest of the web says [Wineburg & McGrew, 2019].

Design Implications¶

Fact checking instruction improves learners' ability to evaluate online information quality, with documented gains in middle school, high school, and college populations Explicit civic online reasoning instruction improves students' evaluation of online sources. [+M]. The key design insight is that novices default to vertical reading — staying within a website and judging its surface features — so instruction must explicitly model the lateral move of leaving the page [Wineburg & McGrew, 2019]. Fact checking should be taught as a small repertoire of fast heuristics applied in seconds, not an exhaustive research procedure; professional fact checkers make judgments in under a minute.

Context¶

Requirements¶

• A taught repertoire of concrete verification moves: lateral reading, click through to the source, find the original, check previous work
• Live web tasks with authentic, messy sources — not sanitized excerpts — so learners practice on the environments where they will actually apply the skill
• Instructor modeling of the verification process (Think-Aloud), making the expert's tab-switching and query formulation visible
• Repeated practice with feedback, since evaluation skill does not transfer from a single lesson

Constraints¶

• Surface-feature heuristics taught as fact checking (judging design, domain suffix, or "About" pages) actively mislead learners; professional fact checkers ignore these cues [Wineburg & McGrew, 2019] [-M]
• Prior knowledge of a topic does not reliably protect against accepting false claims; domain expertise without evaluation strategy still fails on unfamiliar sources [~M]
• Fact checking degrades when learners lack the background knowledge to recognize what needs checking — claims that seem plausible are rarely verified spontaneously [~W]
• Motivated reasoning: learners apply more scrutiny to claims that conflict with their prior beliefs than to congenial ones, so instruction must address bias, not just technique [~M]

Implementation Variability¶

• Lateral reading (the core professional move): open new tabs to see what other sources say about the site or author before engaging with its content
• Reverse image search and provenance tracing: for visual claims, find the original context of a photo or video
• Structured protocols: rubric-driven evaluation (e.g., the SIFT moves — Stop, Investigate the source, Find better coverage, Trace claims) as a scaffold that is later faded
• Corroboration tasks: comparing a claim across three or more independent sources before accepting it

Target Learners¶

• Secondary and postsecondary students, who show large deficits on realistic evaluation tasks — most students fail to distinguish sponsored content from news Explicit civic online reasoning instruction improves students' evaluation of online sources. [+M]
• Professional-track learners (journalists, librarians, health professionals) who must evaluate sources under time pressure
• Less effective as a one-off intervention; gains require distributed practice across the curriculum Distributed practice improves retention. [+S]

Target Learning Goals¶

• Information literacy: evaluating the credibility and reliability of sources
• Critical evaluation: judging evidence quality and detecting misinformation
• Civic reasoning: making informed judgments about public claims and media

Instructions¶

1. Model the lateral move. Using a Think-Aloud, demonstrate leaving an unfamiliar website to search what independent sources say about it — the move novices never make spontaneously.
2. Teach a compact heuristic set. Introduce a small protocol (e.g., SIFT) as Advance Organizers for the verification process, keeping the load low enough to apply in real time Chunking reduces working memory load. [+S].
3. Practice on authentic sources. Assign live-web Case Studies using real websites, including deceptive ones, so learners encounter the actual cues they must read past.
4. Corroborate before concluding. Require learners to check claims against at least two independent sources, treating corroboration as the default standard of acceptance.
5. Fade the protocol. Move from rubric-supported evaluation to independent verification, using Fading as learners internalize the moves.
6. Assess with transfer tasks. Evaluate with novel sources not seen in instruction, since the goal is a portable disposition, not recall of a checklist Assessment for learning improves achievement. [+S].

Related Strategies¶

• Lateral Reading — the core professional technique that fact checking instruction centers on
• Source Evaluation — the broader judgment skill of which fact checking is the active, verification-based component
• Media Literacy Education — the wider curriculum context addressing bias, framing, and production of media
• Teach students a broad set of strategies including sourcing, scrutinizing evidence, and corroboration to enable judging the accuracy of diverse online claims
• Use corroboration across multiple sources, including lateral reading, when lacking relevant prior knowledge
