RADAR


Learning Objectives

After completing this tutorial, you will:

  • understand why it is important to evaluate knowledge
  • have a handy criteria for evaluating knowledge

Introduction

RADAR is an acronym representing a framework for evaluating knowledge sources, to determine whether or not they are appropriate for your research.

  • R is for Relevance
  • A is for Authority
  • D is for Date
  • A is also for Appearance
  • R is also for Reason

Relevance

Relevant knowledge:

  • helps answer your research question
  • is related to your topic
  • can be from any discipline

Quiz: Relevance (optional)

Authority

Authority refers to the author, creator, publisher or keeper of the knowledge. What is their credibility? What are their credentials? For knowledge to be authoritative:

  • the name of the author, creator, publisher, or knowledge keeper, whether a person, organization or institution
  • What is the author or knowledge keeper’s positionality? Is their education, training, occupation or position relevant to the subject?
  • In the case of scholarly/academic sources, does the bibliography, list of references or list of works cited contain relevant, authoritative sources?
  • Does the author or knowledge keeper have a history of creating or sharing credible, reliable information in the field?

Quiz: Authority (optional)

Date

When was the information source written, created and/or last updated? Just because something is older doesn’t mean that it isn’t useful. Consider whether the information source:

  • is the latest and most up-to-date, and whether or not this is important
  • was seminal (meaning it had a strong influence over later research in the field)
  • can be used for historical context

Quiz: Date (optional)

Appearance

The appearance of the information source (i.e. how the information is presented) can sometimes be an indicator of its quality. Scholarly/academic information tends to be presented:

  • with little or no advertising
  • with an abstract describing the content
  • with a bibliography, list of references or list of works cited that support the author’s argument
  • in peer-reviewed, scholarly/academic journals or books

Quiz: Appearance (optional)

Reason

What was the author’s reason for creating the information source? Appropriate scholarly/academic information sources are created:

  • to educate by spreading scholarly/academic information
  • to inform further scholarly/academic research
  • never to entertain
  • never to sell something

Quiz: Reason (optional)

Closing Thoughts

RADAR is only a guideline to help you remember criteria for evaluating scholarly/academic information sources. Not every information source needs to pass every aspect of the RADAR criteria. Use your own judgement.
