Unit: Navigating Digital Texts (Lesson 6 of 30)
Duration: 60 minutes
Class size: 15 students
Year level: VPC Year 10
Subject: Other (Digital Literacy focus)

Curriculum Alignment

Victorian Curriculum Digital Technologies and English focus:

• VCELA421 (English): Investigate how text structures and language features can be used to influence an audience.
• VCDTCD041 (Digital Technologies): Critically analyse and evaluate data and information encountered in digital environments, considering reliability, relevance, accuracy, and bias.
• VCDTCD042 (Digital Technologies): Plan and manage digital projects to create solutions.

This lesson aligns with the Victorian Curriculum general capability of Critical and Creative Thinking by developing students' ability to critically evaluate digital texts and online sources.

Learning Intentions (WALT - We Are Learning To)

• WALT: Assess the reliability of digital sources.

Success Criteria

Students will be able to:

• Identify characteristics of reliable versus unreliable digital sources.
• Analyse sample digital texts to determine their credibility.
• Apply criteria to evaluate sources independently.

Extension Activity

• Create a personalised checklist for evaluating the reliability of sources to support future research and digital literacy.

Lesson Breakdown

1. Introduction & Context (10 minutes)

• WALT reminder: Display the learning intention and success criteria on the board.
• Brief discussion: Why is it important to assess the reliability of digital sources?
• Show examples of trustworthy and untrustworthy sources (e.g., a reputable news site vs. a dubious blog).
• Introduce key vocabulary: reliability, bias, credibility, evidence, authoritativeness.

2. Modelling Evaluation Criteria (10 minutes)

• Present a structured checklist based on Victorian Curriculum principles:
  1. Authorship — Who created the information? Credentials?
  2. Publication — Where is it published? Organisation’s reputation?
  3. Currency — When was it published or last updated? Is the info current?
  4. Evidence — Are claims supported by evidence or references?
  5. Bias — Is the source objective or opinionated?
  6. Purpose/Audience — Why was it created? Who is it for?
• Teacher models using a digital article example or website; think-aloud assessing criteria.

3. Guided Practice: Source Evaluation Task (20 minutes)

• Students work in pairs to evaluate 2-3 digital sources provided by the teacher (mix of reliable and unreliable).
• Use the checklist to decide reliability, discussing evidence for their decisions.
• Teacher circulates, scaffolding and prompting deeper thinking.

4. Class Discussion & Reflection (10 minutes)

• Groups share findings and justify why they judged sources as reliable/unreliable.
• Class discusses how misinformation or unreliable sources could affect decisions/make problems in daily life.
• Teacher summarises key points reinforcing success criteria.

5. Extension: Create Your Own Checklist (10 minutes)

• Advanced learners design their own checklist or rubric with explanations for each item.
• Share their checklists digitally or on posters for the class library of evaluation tools.

Differentiation Strategies

Learner Type	Adaptation
Students learning English	Use simplified language in checklist, provide bilingual glossaries if needed.
Students with additional needs	Provide printed checklists and sentence starters for explanations, one-on-one guidance.
Extension learners	Design personalised checklists, lead small group discussions, create digital presentations.
All students	Visual examples and structured note templates to support organising evaluation data.

---

Resources Needed

• Projector/Smartboard to display examples and checklist
• Printed copies of source examples for group work
• Checklists templates for students
• Markers or digital tools for extension activity

---

Assessment

• Formative assessment through observation of group discussions and checklist application.
• Extension checklist creation demonstrates understanding and reflection on source evaluation criteria.

---

Teacher Reflection Notes

• Consider integrating recent news articles or social media examples relevant to students’ interests.
• Monitor student ability to identify bias and misinformation, adapt next lessons accordingly.
• Foster ongoing discussions of source reliability in future digital literacy units.
