Detailed Lesson Notes
Understanding Credibility and Bias in Sources
Credibility refers to how trustworthy and reliable a source is. Factors affecting credibility include the author's expertise, evidence provided, and the source's reputation. Bias occurs when a source shows a preference or prejudice that affects the information presented, often by emphasizing certain facts or omitting others. Omission is a form of bias where important information is left out, which can mislead the reader. For example, a news article might omit statistics that contradict its main argument, affecting its credibility.
Identifying Faulty Reasoning
Faulty reasoning weakens an argument by using illogical or misleading logic. Common types include: Incorrect premise—when the foundation of an argument is false or unsupported; Hasty generalization—drawing a broad conclusion from insufficient evidence; Either-or fallacy—presenting only two options when more exist. Recognizing these helps students critically evaluate arguments and avoid accepting flawed conclusions.
Ethical Use of Sources and Academic Citation
Using sources ethically means giving proper credit to original authors to avoid plagiarism. Academic citations include information about the source, such as author, title, and publication details, and must be included for both paraphrased and quoted text. Proper citation not only respects intellectual property but also strengthens the credibility of students' own work by showing research depth.
Modes of Delivery for Presenting Research
Students can present their findings in various modes: written reports, oral presentations, or multimodal formats such as videos or slideshows. Choosing an appropriate mode depends on the audience and purpose. Effective presentations clearly communicate the research process, findings, and conclusions, using supporting evidence and citations.
Worked Examples
Worked Example 1
Scenario
Examine this excerpt from a news article that reports on a scientific study but leaves out the study's limitations. Identify any bias or omission and explain how it affects the article's credibility.
Explanation
The omission of the study's limitations is a form of bias because it presents the findings as more conclusive than they are. This reduces the article's credibility by not providing a complete picture, which can mislead readers about the strength of the evidence.
Answer Guide
The article is biased because it omits important limitations of the study, making the findings seem more certain than they really are. This omission lowers the article's credibility.
Worked Example 2
Scenario
Read this argument: "All teenagers are irresponsible because I saw two teenagers littering." Identify the type of faulty reasoning and explain why it is incorrect.
Explanation
This is a hasty generalization because the argument draws a broad conclusion about all teenagers based on only two examples. This reasoning is flawed because it does not consider the larger population or other evidence.
Answer Guide
The argument uses a hasty generalization by assuming all teenagers are irresponsible based on just two instances, which is not enough evidence to support such a claim.
Worked Example 3
Scenario
Here is a paraphrased statement from a source: "Many experts agree that climate change affects weather patterns." Create an academic citation for this paraphrase.
Explanation
An academic citation should include the author's name, publication year, and source title or publisher depending on the citation style. This gives credit to the original source and allows readers to locate it.
Answer Guide
(Author's Last Name, Year) or a full citation depending on the style, for example: (Smith, 2020).
Worked Example 4
Scenario
You are preparing an oral presentation on your research findings. What are some key elements you should include to effectively communicate your analysis of source credibility and bias?
Explanation
Key elements include a clear explanation of how you evaluated the sources, examples of bias or omissions found, identification of any faulty reasoning, and proper citation of your sources. Using visuals or examples can also enhance understanding.
Answer Guide
Include explanations of source credibility and bias, examples of omissions, identification of faulty reasoning, and cite sources properly. Use clear language and visuals to support your points.

Guided Practice
Guided Practice 1
Prompt
What does it mean if a source is credible?
Teacher Answer Guide
A credible source is trustworthy and reliable because it provides accurate, well-supported information from an expert or reputable publisher.
Guided Practice 2
Prompt
Identify one example of bias in a news article and explain how it affects the information presented.
Teacher Answer Guide
An example of bias is when a news article uses emotionally charged language to favor one side, which can influence readers to accept that viewpoint without considering other perspectives.
Guided Practice 3
Prompt
Given a short text that claims "Everyone who uses social media is addicted," explain what type of faulty reasoning this is and why it is incorrect.
Teacher Answer Guide
This is a hasty generalization because it makes a broad claim about all social media users based on insufficient evidence, ignoring that many people use social media without being addicted.
Guided Practice 4
Prompt
Analyze a provided paragraph for omission bias. What important information is missing, and how does that omission affect the argument?
Teacher Answer Guide
The paragraph omits data about alternative viewpoints, which makes the argument one-sided and less credible because it does not acknowledge other relevant evidence.
Guided Practice 5
Prompt
Create a brief outline for a multimodal presentation that evaluates the credibility and bias of three different sources, including how you will cite them ethically.
Teacher Answer Guide
Outline includes: Introduction explaining criteria for credibility and bias; analysis of each source with examples of bias or credibility factors; discussion of any faulty reasoning; citations for each source displayed on slides or in notes; conclusion summarizing findings and ethical use of sources.

Guiding Questions
- What makes a source credible or biased?
- How can omission affect the reliability of information?
- What are common types of faulty reasoning?
- How do you cite sources to avoid plagiarism?
- What mode of delivery best suits your presentation and why?
Common Misconceptions
- Bias always means the source is false or useless. (Bias can affect perspective but does not always invalidate all information.)
- If a source is published online, it is automatically credible. (Online sources vary widely in credibility.)
- Citing sources is only necessary for direct quotes, not paraphrases. (Paraphrased ideas also require citation.)
- Faulty reasoning always involves obvious mistakes. (Some faulty reasoning can be subtle and harder to detect.)
Differentiation
Support and Intervention
Provide sentence starters for identifying bias and faulty reasoning. Use graphic organizers to help students categorize types of faulty reasoning. Offer citation templates to guide proper referencing.
English-Language Learner Support
Use visuals and examples to explain credibility and bias. Pre-teach key vocabulary with definitions and examples. Allow oral responses or presentations to support language development.
