Finding Trustworthy Sources

Overview

This is lesson 4 of 12 in Critical Lenses, Powerful Readings. Students build on their research hypothesis and introductory library skills by locating, evaluating and selecting credible critical sources for an AS91479 response.

Learning intentions

• WALT locate critical sources using precise search terms.
• WALT evaluate a source’s authority, relevance, currency, purpose and evidence.
• WALT distinguish scholarly criticism from unreliable commentary.
• WALT justify how two sources will support a specific hypothesis.

Success criteria

• I can search using lens, author and text keywords.
• I can explain why a source is credible, useful or limited.
• I can use evidence from a source evaluation to make a justified choice.
• I can record accurate bibliographic details for sources I may use.

Curriculum links

• Develop an informed understanding of literature and/or language using critical texts by selecting, evaluating and synthesising information.
• Respond critically to significant aspects of studied written texts, supported by specific evidence.
• Use reading, viewing, research and writing processes to create meaning and communicate a coherent argument.
• Develop the refreshed curriculum capabilities of critical thinking, managing self, participating and contributing, and using language, symbols and texts.

Lesson structure (60 minutes)

1. 0–5 min · Source prediction warm-up. Teacher displays four source descriptions—an academic journal article, a personal blog, a recent news feature and a fabricated “expert” page—using the source prediction slides, then asks, “Which would you trust first, and why?” Students individually predict a reliability ranking before briefly comparing reasoning with a partner.

2. 5–17 min · Search modelling. Teacher or librarian demonstrates a database and library search using a lens, author and text title, recording useful search terms on the search demonstration slides. Think aloud: “I am not accepting the first result; I am checking who produced it, what evidence it uses and whether it answers my question.” Students adapt the model to their own hypothesis and suggest ways to narrow or improve a search.

3. 17–27 min · Reliability ranking. Teacher distributes the source evaluation and reliability worksheet and provides groups with the prepared authentic and fabricated source extracts. Students rank the sources along the classroom reliability line, then justify their decisions by checking authority, relevance, currency, purpose and evidence. Prompt: “Can a source be credible but still limited?” Address misconceptions, including polished design being proof of reliability, recent information always being best, and famous authors being beyond question.

4. 27–38 min · Fake-versus-authentic investigation. Teacher assigns each group an authentic/fabricated pair and models triangulation: checking the author, publication details, claims, references and agreement with other reliable information. Students annotate both sources on the worksheet, identify at least three clues, and prepare a short verdict explaining which source is more useful for their hypothesis and why.

5. 38–50 min · Independent source search. Teacher reminds students of the selection criteria on the independent research instructions and conferences with individuals or pairs. Students independently locate at least three potentially useful critical sources, record search terms and database notes, and complete evaluation forms for at least two sources. They must record enough bibliographic information to retrieve and cite each source accurately.

6. 50–56 min · Partner challenge and checkpoint. Teacher pairs students to challenge one source choice with the question, “What makes this source useful for your specific hypothesis?” Students explain one source’s strongest feature and one limitation, revise their evaluation if needed, and show their search terms, database notes and completed criteria to the teacher for a quick checkpoint.

7. 56–60 min · Exit ticket and homework. Teacher displays the final prompt on the exit ticket and homework slide. Students rank one investigated source, cite its strongest feature and identify one limitation. For homework, they obtain or download two suitable sources and record full bibliographic details for the next lesson.

Resources

• the “Finding Trustworthy Sources” slide deck
• the source evaluation and reliability worksheet
• Library or classroom devices with database access
• Prepared authentic and fabricated source extracts
• Reliability ranking line displayed in the classroom
• Search demonstration account or screenshots
• Citation examples and students’ research hypotheses
• Highlighters, pens and access to a librarian

Assessment

• During modelling, check whether students generate precise lens, author and text search terms rather than broad topic searches.
• Review group rankings, annotations, database notes and completed evaluation criteria; question unsupported claims about reliability.
• Collect exit tickets to identify whether students can make a justified judgement while acknowledging a source’s limitation.

Differentiation

• Provide a curated source bank, search templates, a keyword-builder and sentence starters such as “This source is useful because…” and “Its limitation is…”.
• Offer paired navigation, librarian support, printed source alternatives, enlarged text and screen-reader-compatible documents for EAL learners and students with SEN.
• Pre-teach authority, relevance, currency, purpose, evidence, credible, limitation and triangulation with brief examples; allow students to rehearse explanations orally before writing.
• For advanced learners, compare two credible critics who disagree and identify how their purposes, theoretical assumptions or evidence shape their conclusions.
