Evaluate: Judging Information Quality

Evaluate is the fifth pillar in the SCONUL Seven Pillars of Information Literacy. It means judging the quality, reliability, relevance, and usefulness of information. It also includes reviewing the research process itself.

After students gather information, they should not use every source automatically. They need to decide which sources are trustworthy, which are useful, and which should be rejected or used carefully. This is especially important in digital learning, where students may find websites, videos, social media posts, AI-generated answers, blogs, reports, and images of very different quality.

Definition

A simple classroom definition is:

Evaluate means judging whether information is reliable, relevant, accurate, and suitable for the purpose.

Evaluation is not only about saying whether a source is “good” or “bad.” A source may be useful for one task but unsuitable for another. For example, a short blog post may be useful for getting a simple classroom example, but it may not be strong enough as evidence in an academic essay. A research report may be reliable but too advanced for young learners.

Students need to ask both questions:

• Is this source trustworthy?
• Is this source useful for my task?

A source should meet both conditions before it is used seriously in school work.

What Students Evaluate

Students should evaluate more than one thing. They should evaluate individual sources, information claims, evidence, and their own research process.

This wider view is important. A student may gather many sources but still produce weak work if the sources are not evaluated carefully.

Source Evaluation Criteria

Authority

Authority means checking who created the information. Students should identify the author, organization, publisher, or platform.

Useful questions include:

• Who wrote or produced this source?
• Is the author named?
• What are the author’s qualifications or experience?
• Is the organization known and reliable?
• Can I verify the author or organization elsewhere?

Authority does not mean accepting a source blindly. Even expert sources should be read carefully. However, unknown or unclear authorship is a warning sign.

Accuracy

Accuracy means checking whether the information is correct. Students should look for facts, explanations, statistics, examples, and consistency with other reliable sources.

Questions include:

• Are the facts correct?
• Are there spelling, grammar, or factual errors?
• Do other reliable sources confirm the same information?
• Are claims supported or only stated?

If a source makes many unsupported claims, it should be used cautiously or rejected.

Relevance

Relevance means checking whether the source fits the task. A reliable source is not always relevant.

Students should ask:

• Does this source answer my question?
• Is it suitable for my subject and level?
• Is it too simple, too advanced, too broad, or too narrow?
• Does it provide information I can actually use?

For example, a university research article may be reliable, but a primary school teacher may need a simpler classroom-friendly explanation for young learners.

Currency

Currency means checking whether the information is recent enough. Some topics change quickly, such as technology tools, online safety risks, AI tools, health guidance, laws, statistics, and current events.

Students should ask:

• When was this source published or updated?
• Is the date visible?
• Does this topic require recent information?
• Are the links or references still active?

Older sources are not always bad. For historical topics, older documents may be valuable. The question is whether the date is suitable for the purpose.

Evidence

Evidence is the support used for claims. A strong source usually provides data, examples, references, documents, direct observations, expert explanation, or links to original sources.

Students should ask:

• What evidence is given?
• Is the evidence relevant?
• Can the evidence be checked?
• Does the evidence support the claim?
• Are statistics explained clearly?

A claim without evidence is weak, even if it is written confidently.

Bias and Purpose

Bias means a source presents information in a one-sided way. Purpose means the reason the source was created.

Students should ask:

• Is the source trying to inform, persuade, sell, entertain, or influence?
• Is the language balanced or emotional?
• What viewpoint is presented?
• What information may be missing?
• Who benefits if readers believe this message?

Bias does not always make a source useless, but it means students should read carefully and compare with other sources.

Evaluating the Research Process

The SCONUL Evaluate pillar is not only about judging sources. Students should also review how they searched.

They can ask:

• Did I understand the question clearly?
• Did I use suitable keywords?
• Did I search in the right places?
• Did I use more than one source type?
• Did I gather enough information?
• Did I rely too much on one website or tool?
• Did I check sources before using them?
• Do I need to return to Identify, Scope, Plan, or Gather?

This is important because research is not always linear. If students discover weak results, they may need to revise the question, change keywords, search a different database, or gather new sources.

Classroom Meaning

Teachers can develop evaluation skills through short activities. Students can compare two websites, rank sources from strongest to weakest, identify unsupported claims, check dates, or discuss why one source is more suitable than another.

For example, a teacher may give students two sources about online safety. Students can compare:

• author or organization
• date
• purpose
• evidence
• audience
• usefulness for the assignment

Then students explain which source they would use and why.

A strong classroom instruction is:

“Do not only list your sources. Explain why each source is suitable.”

This helps students move from collecting information to judging information.

ICT Connection

Evaluation is essential in ICT-supported learning. Students use search engines, online videos, websites, digital libraries, AI tools, social media, and learning platforms. These tools provide quick access to information, but they do not guarantee quality.

Students should be especially careful with:

• websites without authors or dates
• copied content
• emotional headlines
• edited images
• AI-generated answers
• social media claims
• outdated statistics
• sponsored content
• sources that do not show evidence

AI tools require particular care. They may produce fluent answers that sound confident but contain errors, missing context, or invented details. Students should verify AI-supported information using reliable sources before including it in school work.

Answer

Evaluate means judging the quality, reliability, relevance, and usefulness of information, data, sources, and the research process.

Common Mistakes

A common mistake is to believe that the first search result is the best source. Search ranking does not prove reliability.

Another mistake is to judge a source only by appearance. A professional design, logo, or clear layout does not guarantee accuracy.

A third mistake is to use a source only because it agrees with the student’s opinion. Good evaluation requires students to consider evidence, not only preference.

A fourth mistake is to evaluate sources but ignore the research process. If the search strategy was weak, the gathered sources may also be weak.

The Evaluate pillar helps students become careful users of information. It teaches them to judge sources, question evidence, recognize bias, and improve the research process before presenting final work.
