    1 - Introduction

    Why Source Reliability Matters in Online Research

    Imagine you are doing your homework and find some exciting information online, only to learn later that it is not correct. This can cause mistakes in your schoolwork and make you lose trust in things you find on the internet.

    Reliable sources give you correct facts, help you stay away from wrong information, and let you make good choices. On the other hand, unreliable sources might have fake information or be made just to get your attention without caring about what is true. In this lesson, you will learn ways to spot reliable sources, so you can do research well and with confidence.

    Objectives of This Lesson

    • Understand the characteristics of reliable and unreliable sources.
    • Recognise common indicators of poor-quality information.
    • Apply a checklist to assess source reliability.
    • Practise evaluating sample sources through activities.
    By the end of this lesson, you will have useful tools to check online information, helping you spot trustworthy facts from those that are not.

    2 - What is a Reliable Source?

    A reliable source is a website, article, or piece of information that you can trust. It is based on checked facts, reviewed by experts, and does not try to trick you.

    Characteristics of Reliable Sources

    Reliable sources have several important features that make them trustworthy. These include:

    • Accuracy and Fact-Checking: The information is correct and supported by proof that can be checked, such as science experiments, history records, or official reports. This checking helps to make sure the content is true.
    • Authorship by Experts or Reputable Organisations: The content is made by people who know a lot about the topic, such as teachers, scientists, or trusted groups like RTÉ or school journals. Their knowledge gives the information strength.
    • Timeliness: The material is up to date and includes the latest changes, which is very important for subjects that change quickly like science, technology, or news.
    • Balance and Objectivity: The source shows different views on a topic without unfairly liking one side, helping you get a fair and full understanding.

    Characteristics of Unreliable Sources

    On the other hand, unreliable sources have features that make them less trustworthy. It is important to spot these to stay away from wrong information:

    • Presence of Errors: These sources might have wrong facts, spelling mistakes, or no proof to back them up, showing they were not checked properly.
    • Unknown or Questionable Authorship: The content might come from people or websites you cannot identify or that do not show their qualifications, making it hard to know if the information is good.
    • Outdated Information: The content does not include recent changes, which can make it wrong or not useful now.
    • Bias or Partiality: These sources often push just one view, usually to convince you or sell something, instead of giving fair information.
    Remember, reliable sources help build good knowledge, while unreliable ones can lead to mistakes or wrong ideas.

    3 - Spotting Red Flags

    It is important to know that not all information on the internet is true or fair. Some signs, called 'red flags', can show that a source might not be trustworthy. These could mean it is trying to trick you, get your attention in a bad way (called clickbait), or is just not good quality. Learning to spot these signs will help you stay away from bad information and make better choices when you look things up online.

    Common Red Flags in Online Sources

    Here is a list of common red flags. Each one has an explanation and examples to help you understand why it might mean the source is not reliable.

    • Clickbait Headlines: These are exciting titles that make you want to click, like 'You Won't Believe What Happened Next!' or 'The Shocking Truth Revealed!'. They promise amazing things, but the story inside is often not true or not as good as promised. These headlines care more about getting clicks than telling the truth.
    • Bias or Unfair Views: This happens when the information strongly supports one side without showing other ideas. For example, an article might like one team a lot or try to sell you something by only saying good things. These sources want to change your mind, not give fair facts.
    • No Sources or Proof: Good information should have links to where it came from, like studies or expert ideas. If a source says big things without any proof, it might not be true.
    • Too Many Ads or Pop-Ups: Websites with lots of adverts or things that pop up might care more about making money than giving true information. They want you to click for money, not to help you learn.
    • Exciting or Over-the-Top Words: Words like 'shocking', 'secret', 'unbelievable', or 'explosive' are used to make you excited. But often, there are no real facts behind them, and it's more like a fun story than true information.
    Practising how to spot these red flags is important. It helps you become a smart researcher. If you see any of these, stop and check more before you believe it. Look for other sources too.

    4 - Your Evaluation Checklist

    To help you check online sources well, we have made a simple checklist with five questions. This checklist is a good way to decide if a source is reliable when you are doing research. You should use this checklist every time to get better at finding trustworthy information.

    Reliability Evaluation Checklist

    1. Who is the author?
      Check if the author knows a lot about the topic or works for a trusted organisation. Look at the 'About Us' or 'Author' part of the website to see their qualifications and background.
    2. Is the information accurate?
      See if the information has facts that you can check, with proof like links to other good sources. Look for signs that they did careful research and checked the facts to make sure it is correct.
    3. When was the information published?
      Find out when the information was published to make sure it is up to date. For things that change quickly, like science or news, old information might not be right anymore.
    4. What is the purpose of the source?
      Think about why the source was made. Is it to teach you facts fairly, or to sell something or push one idea? Sources that want to sell or convince might not care as much about true facts.
    5. Does the source present a balanced view?
      Check if the source shows different sides of the topic or just one side. A good source tries to be fair, without too much bias, and shows different opinions.
    We suggest saving this checklist in your digital notes so you can look at it easily. Use it when you search online next time to practise and get better at checking sources.

    5 - Activity: Evaluate Sample Headlines

    In this activity, you will use the skills you have learned to check some example headlines and search results. These are shown as if they came from a search on the internet for 'evidence of Bigfoot sightings'. This exercise will help you practise finding reliable sources in an organised way.

    Please spend about 10–15 minutes to finish this activity.

    Purpose of the Activity

    The goal is to help you remember how to check if sources are reliable. You will use the evaluation checklist from earlier. This will teach you to spot red flags and decide if the information can be trusted. It will make you better at doing research.

    Detailed Instructions

    1. Look at the sample headlines listed below. Think of them as results from an online search for 'evidence of Bigfoot sightings'.
    2. Use the five-question reliability evaluation checklist for each headline: Who is the author? Is the information accurate? When was it published? What is the purpose? Does it present a balanced view?
    3. For each headline, write down what you think, including any red flags you see (such as clickbait, bias, or no sources) and why you decide it is reliable or unreliable.
    4. Write your answers on paper or in a digital notes app to look at later.

    Sample Headlines for Evaluation

    Headline Source Description
    'Bigfoot Sighting Confirmed by Local Hunter!' Posted on a personal blog with no identifiable author. Includes exaggerated language and no photos or evidence. The site contains ads and no contact information.
