Description¶

Search strategy scaffolds are explicit supports — query templates, source-evaluation checklists, staged search plans, or modeled searches — that structure how learners locate information. Rather than assuming students already know how to find and judge information, the strategy makes the search process itself an instructional target: learners are taught to decompose an information need, generate and refine queries, scan results strategically, and evaluate sources before using them.

Design Implications¶

Unscaffolded search is dominated by keyword matching and surface cues; learners click the first plausible result and rarely revise [~M]. Scaffolds work because they externalize the expert's information-problem-solving cycle — defining the problem, planning, evaluating, monitoring — which novices otherwise skip Brand-Gruwel et al. found students rarely regulate their search process spontaneously. [+M]. Effective scaffolds pair process structure with evaluation criteria, since locating information is worthless if learners cannot judge its credibility; explicit instruction in evaluating sources measurably improves the quality of information students select Civic online reasoning instruction improves students' evaluation of online sources. [+S].

Context¶

Requirements¶

• A genuine information need or inquiry question that motivates the search (Anchored Instruction provides such contexts)
• Explicit evaluation criteria (authority, evidence, currency, corroboration) taught before or during searching
• A model of expert searching — a Think-Aloud demonstration of query formulation and result triage
• Opportunities to revise queries and compare sources, not a single one-shot search

Constraints¶

• Scaffolds that prescribe a rigid sequence can prevent learners from developing adaptive search behavior; overly prescriptive checklists produce compliance without transfer [-M]
• Scaffolds lose effectiveness when learners already possess strong domain and search expertise — the guidance becomes redundant and slows expert searchers [~M]
• Query templates tied to one database or interface transfer poorly to new tools unless the underlying decision rules are made explicit [-W]
• Evaluation checklists alone (e.g., "check the author's credentials") are less effective than teaching lateral reading — leaving a page to check what others say about it — because hostile or deceptive sources can satisfy checklist criteria [X for checklist-only approaches with deceptive sources]

Implementation Variability¶

• Query scaffolds: sentence frames ("How does ___ affect ___?"), question decomposition charts, keyword brainstorming grids
• Evaluation scaffolds: lateral-reading routines, source-comparison tables, credibility criteria cards
• Process scaffolds: staged search plans (explore → focus → verify), search logs with reflection prompts
• Embedded scaffolds: software prompts and hints within inquiry environments that adapt to the learner's current search phase

Target Learners¶

• Novices with little prior knowledge of the topic, who cannot judge relevance or credibility from content alone and default to surface cues [~M]
• K-12 and early undergraduate students, who show large gains from explicit online-reasoning instruction Civic online reasoning instruction improves students' evaluation of online sources. [+S]
• Less beneficial for domain experts, who already possess the schemas needed to evaluate results efficiently [~M]

Target Learning Goals¶

• Information literacy: locating, evaluating, and selecting sources
• Inquiry skills: decomposing a question into searchable sub-questions
• Critical evaluation: judging source credibility and corroborating claims across sources
• Self-regulated learning: planning, monitoring, and revising one's own search process

Instructions¶

1. Present an authentic information need or inquiry question, ideally embedded in a problem context (Anchored Instruction).
2. Model an expert search with a think-aloud: formulating the need, generating keywords, scanning results, rejecting weak sources aloud (Think-Aloud Modeling).
3. Provide a query scaffold — question decomposition or sentence frames — and have learners draft their own search plan.
4. Teach evaluation criteria explicitly, emphasizing lateral reading and corroboration across independent sources (Civic Online Reasoning [+M]).
5. Have learners execute searches, log decisions, and compare selected sources with peers (Comparing Cases [+W]).
6. Fade the scaffolds: move from full search plans to prompts to independent searching as learners show competent self-regulation.

Related Strategies¶

• Think-Aloud Modeling — the demonstration method that makes expert search decisions visible
• 3-Source Rule — a corroboration scaffold that forces learners to triangulate across sources
• A Finder's Guide to Facts — a published evaluation routine for judging online claims
• Provide explicit prompting instruction and expert scaffolding before or during novice LLM activities

Examples¶

• Stanford History Education Group — Civic Online Reasoning curriculum (https://cor.stanford.edu): free lessons teaching lateral reading and source evaluation; classroom studies show large gains in students' ability to evaluate online sources Civic online reasoning instruction improves students' evaluation of online sources. [+S]
• Search logs in inquiry units: students record query versions, rejected results, and rejection reasons, making the search process an object of reflection and assessment
• Question decomposition charts in library instruction: librarians scaffold a research question into sub-questions and keyword sets before students touch a database
