Topic 4: INFORMATION LITERACY (EVALUATION)
Terms in this set (24)
What is Information Evaluation?
The systematic determination of the merit and worth of information.
How is information used in business?
-In business, we often use information to reduce uncertainty.
-The more uncertainty, the more we seek information in order to reduce that uncertainty: we assume all information is of good quality.
-Poor quality information is ineffective at reducing decision uncertainty.
What is quality information and why is it important?
-it is information that is fit for its intended use.
-If you use bad information as the basis for a decision, you are probably going to make a bad decision.
-the characteristics of information is what makes it useful or not useful.
How can you deal with information overload?
-Withdrawal: Disconnecting from sources of information; not checking email, turning off the television, not surfing the Web and so on.
-Filtering: knowing what information we
need and what information merits attention and use, which makes knowing how to evaluate information a critical skill in today's information rich world.
How does Information Evaluation relate to Information Overload?
-Filtering assumes we evaluate relevancy to what we are working on at the time.
-We also evaluate the information's use depending on whether the information is too old, untrustworthy, or is otherwise of unquestionable quality.
What is Intrinsic Information?
includes dimensions of quality that are
important regardless of the context or how the information is represented.
What is Contextual Information?
Includes the dimensions that may be viewed
differently depending on the task at hand.
What is Representational Quality?
Concerns how the information is provided to the user.
What is Accessibility Quality?
Has to do with whether authorised users can easily access the information.
What is in the Intrinsic Dimension?
-Accurate: correct, free from error and reliable.
-Believable: regarded as true and credible.
-Objective: Free from bias.
-Reputation: trusted or highly regarded in terms of
their source or content.
What is in the Contextual Dimension?
Value- Added: Beneficial and provide advantages from their use.
Relevant: Applicable and useful for the task at hand.
Timely: Sufficiently up-to-date for the task at hand.
Complete: Of sufficient depth and breadth for the task at hand.
Appropriate amount of information: The quantity or volume of available data that is needed.
What is the process for information literacy?
you need to know:
1) how to search,
2) how to filter and process,
3) how to produce, and
4) how to synthesise.
How do you search?
-what keywords should you use?
-Use advanced searching techniques (limit to blogs, discussions,
social networks) and filter by time, date and sources.
-Google Scholar (for journal articles, patents and law).
-Find data outside a search engine, for example USA Spending.gov, Australian Data Archive, Census data (ABS)
How do you filter and process?
To think critically...
-"what is the intent of the author? Is it to inform you, or is it to make a point? How does the information make you feel? Is your intent in consuming this information to confirm your
beliefs or find the truth? Are you capable of viewing the information objectively? "
-Important is also how to make sense of numerical data.
-Spreadsheet reading skills will help to sort and see the facts: Other tools such as Google's Fusion Tables, which helps visualise data.
How do you Produce and Synthesise Information?
-Ability to communicate, take feedback and exchange information with others.
-Tools include Blooger, (Blog‐publishing service), Wordpress (website creation) and TypePad (weblogs and photo albums).
-Creating and publishing content are critical to information literacy " because they help us to understand better what we say, both through the internal reflection it takes to make our findings comprehensible to others, and through the public
feedback we get from putting our content in front of others."
-After the information is retrieved, filtered, published , you must synthesize the feedback into your ideas - to make them clearer and more comprehensive.
How do we evaluate the usefulness of information?
-If the information is not useful, then there is no need to assess its believability.
-To determine whether information is useful, evaluate whether the information is relevant, appropriate and sufficiently current. Each of these is a "go, no‐go" assessment.
How do we evaluate the relevancy of information?
-the degree to which the information is
pertinent to the task at hand.
-Will this information help me accomplish my task?
-There are varying degrees of relevance, with experience you will be able to determine what degree of relevance merits further evaluation.
How do we evaluate the appropriateness of information?
-Is the information suitable for your purpose?
-You will need to assess the level of detail and the depth of the information in light of your information needs.
-If you are researching a new technology when preparing a report for your manager, the information contained in a high school student's report may not be appropriate for your use.
-This is a context‐dependent question.
How do we evaluate the currency of information?
-How current you need the information to be?
-If you are seeking information related to rapidly evolving topics, such as information technology, you may need information that is very up‐to‐date.
-Determining the currency of Web‐based information is often difficult.
How do we evaluate the credibility of information?
-Evaluating the credibility of an information source can be tricky in many cases and relatively straightforward in others.
-More formal publications, such as peer‐reviewed journals, often include short author biographies. If the author has written widely on the topic in reputable sources, s/he probably has sufficient expertise to merit using the information.
-In some cases, however, it is almost impossible to determine who wrote the information. If the information is provided by a respected organisation you can usually trust that the individual who created or compiled the information is knowledgeable on the topic.
How do we evaluate the objectivity of information?
-First consider the source of the information. -Language that is more fact‐based and neutral is more likely to be objective.
-If the topic is controversial, all sides should be presented.
-Information is often biased, sometimes intentionally, sometimes unintentionally.
How do we evaluate how supportive information is?
-Claims without support should not be trusted.
-When support is offered, you should evaluate the quality of the support.
-Consider the reasonableness of the claim - extraordinary claims?
-The claim should be testable.
-This does not mean that you have to actually test the claim, but if you can see no reasonable way to test the claim be reluctant to rely on the information.
How do we evaluate the comprehensiveness of information?
-Assessing comprehensiveness requires assessing the depth and breadth of the information.
-Breadth concerns whether all aspects of a topic are covered while depth concerns the level of detail provided.
-Look for obvious gaps in information.
-Throughout your evaluation, keep in mind the context of your particular task.
What is a scholarly article?
-Articles written by researchers or scholars in the discipline.
-Articles are often peer reviewed : Sound argument and research methodology, makes a contribution to the field.
-Sometimes Specialised discipline terminology or jargon used.
-Most articles are preceded by an Abstract and followed by a comprehensive list of References.
