There are two parts to each Big6 Skill. These parts help you to understand the meaning of each skill.

slide5

• This process does not require all students to do things in exactly the same way.

• Everyone has differences in personal style.

• There are many paths to the same end.

slide6

#1 Task Definition

• Define the problem

What is the problem to be solved?

Determine what is required for the assignment.

Select and broaden or narrow the topic.

Form questions based on topics and subtopics.

slide7

Big6 # 1 Task Definition

Determine a purpose and need for information

Information Problem:

Natural disasters strike the world in many different forms. What is _______________ and what “effects” result from this occurrence?

slide8

NATURAL DISASTERS/FORCES OF NATURE:

They have the power to shake the universe. They helped form the earth beneath our feet. They can bring both blessings and devastation. No human can control them. No man can fully comprehend their awesome majesty. No year since the beginning of time has the earth failed to witness their coming. Natural disasters can happen at any time or place. They can bring sorrow, but they can also teach important lessons about who we are, what is important to us, and what joys life can hold for every human being.

slide9

Big 6 #1 Task Definition

What am I supposed to find out?

I am supposed to find out what natural disasters are, examples of natural disasters, how they are different, and what the effects of them are on people and the world.

slide10

#1 Task Definition

• Identify the information requirements of problem

What information is needed in order to solve the problem or make the decision?

Pick out keywords in the question or assignment.

Recognize information is needed from at least three sources.

slide11

What information do I need in order to do this?

(Consider listing in question form the information you feel you need to know at this time)

What is a natural disaster?

What is a “force of nature”?

What are examples of natural disasters?

What is meant by “effects?”

How does a particular natural disaster affect people and the world?

slide12

#1 Task Definition

Determine statements or keywords that require evidence for support.

Recognize need to gather information from people through interviews, surveys or questionnaires.

slide13

IDENTIFY INFORMATION

  • Types of information - facts, opinions, primary,secondary
  • •Amount of information - single source, a few, comprehensive
  • • Format of information - text, graphics, audio, video
slide14

#2 Information Seeking Strategies

• Determine the range of possible sources

What are all possible sources of information?

Brainstorm what sources can and should be used to find out the correct information.

Think “far out!”

slide15

#2 Information Seeking Strategies

• Select the best sources

What are the criteria for determining a relevant source?

?????????

slide16

• Accuracy

• Completeness

• Reliability (authoritative)

• Preciseness

• Validity (on target)

• Availability

• Currency

• Ease of use

• Cost

• Entertainment (is fun)

slide17

Which criteria is most important?

It depends on the assignment and the student.

slide18

Big6 #2 Information Seeking Strategies

Examine alternative approaches to acquiring information.

slide19

PRINT:

  • Encyclopedia •Almanac
  • Reference books

NON-PRINT:

• Student Resource Center

• SIRS Knowledge Source

• World Book Online Encyclopedia

• web sites

slide20

#3 Location & Access

• Locate sources

* To save time and effort, find the Index, the file that organizes the content of a source alphabetically for easy searching and location.

Everyday indexes: (examples)

•telephone/phone book

•stores in mall/mall directory

•television shows/TV guide or newspaper

•food in store/overhead aisle index

slide21

#3 Location & Access

• Locate sources

• Find information within sources

*Keywords/synonyms

Consider alternative descriptive words that represent the topic

Use graphic organizers (charts and mind maps) to help brainstorm keywords

slide22

#3 Location & Access

*Boolean searching in

Electronic databases

In electronic indexes, search results can be expanded or narrowed by linking terms with a Boolean term such as “or,” “but not,” or “and.”

slide23

Internet Search Tips

“Keys” to Effective Internet Searching

slide24

Internet Search Tips:

Task Definition

* Clearly define your information need

* What do you need/want to know?

* How much information do you need/want?

Hint: Use general library resources, such as encyclopedias, other reference and non-fiction books, before you begin using the Internet.

slide25

Internet Search Tips

Information Seeking Strategies

*Does your topic…Have distinctive words or phrases?

*If your topic does have distinctive words or phrases, then enclose the word(s) or phrase(s) in “quotes”.

*Example: “coronary heart disease”

slide26

Internet Search Tips

Location & Access

*Carefully select your search terms.

*Use synonyms, alternates, broader and/or narrower search terms to expand or narrow your search if necessary.

slide27

Internet Search Tips

Location & Access

*If your topic has no distinctive words or phrases, then your search requires more than one term with AND or +.

*Example: health and wellness

slide28

Internet Search Tips

Location & Access

*Use advanced search techniques such as truncation & Boolean logic

*Truncation is used to expand results

*A common truncation symbol is “*” (asterisk)

slide29

Internet Search Tips

Location & Access

*Use the truncation search technique. Truncation: * (asterisk)

*For example, a search on the word: child* would also search for: childish, children, children’s

slide30

Internet Search Tips

Location & Access

*Use the Boolean logic search technique. Boolean logic enables a searcher to define sets and search on sets using Boolean operators.

*The principal Boolean operators are:

AND (intersection)

OR (union)

NOT (difference)

slide31

Internet Search Tips:

Location & Access Information Use

*When searching the Internet you may need to vary your approach.

*Carefully and accurately record your findings.

*Carefully organize your bookmarks within meaningful headings.

slide32

Internet Search Tips:

Information Seeking Strategy

*Don’t bog down in any search strategy that doesn’t work.

*Get help whenever you need it.

slide33

Determining Web Page Validity

Internet searches might yield hundreds of relevant Web pages, but not all of them will be valid or useful. Understanding the URL (uniform locator or Web address) is an important first step.

• Look at the domain to the right of the dot or period.

slide34

The last 3 letters indicate the general purpose of the host group. Here are the most common domains and their meanings:

edu = schools, colleges, universities; gov = Government agencies; org = Organizations (non-profit); mil = Military; com = commercial business; net = Network organizations

slide35

EXAMPLE:

News about NASA on a site with a domain name ending in “com” - question validity. WHY?

What if the address is www.nasa.gov? - means Web site is hosted by NASA - info should be reliable.

Because a Web site has the .edu doesn’t guarantee validity either. A long URL could be a student’s page.

slide36

Internet Search Tools

• Evaluate your search tools.

• Evaluate your result lists.

• Evaluate the author’s credentials.

• Evaluate the sites you plan to use.

slide38

#4 Use of Information

•Engage (read, hear, view) the

information in a source

Look for “relevant” information,

or information that is “on the topic,”

based on your task definition.

Relevance can be based on recency,

depth/scope, accuracy, clarity and novelty.

slide39

#4 Use of Information

• Extract relevant information

This is where the “rubber meets

the road!”

Information that you consider to be relevant

should be highlighted or marked in some way.

slide40

Highlighting

1. Highlight or underline the main-idea sentences or phrases, thesis statement, supporting evidence and key words. Skim and scan for only relevant information.

Circle large portions of important text, diagrams or charts that contain main concepts explanations, or examples.

3. Design a coding system of stars, Xs, exclamation points that can be written in the margins to label main ideas or important vocabulary words.

slide41

Notetaking

Three steps:

Identify keywords and related words in the question.

Skim and scan for relevant information. Read the first and last paragraph of sections for summaries of the content and the first and last sentences of paragraphs to get an impression of the topic. Move your eyes quickly over the reading material looking for one specific point.

Extract or pull out needed information. Toss aside trash words, unnecessary sentences and phrases.

slide42

#5 Synthesis

Synthesis is the result, the output part of the information process. It can be writing a research paper, but it can also be:

• answering multiple choice questions on a test

• writing a poem or short story

• making a decision on where to go for dinner

slide43

#5 Synthesis

•Organize information from multiple

sources

- By category

- As a continuum (small/large)

- Alphabetically

- By time

- As a story (beginning to end)

- Or any combination of the above

slide44

#5 Synthesis

• Present the result

“What the result should look like” should be part of Task Definition and “What the original purpose” was should be part of Synthesis.

How does technology play a role in synthesis?

slide45

#6 Evaluation

• Judge the result (effectiveness)

• Judge the process (efficiency)

-Determine strengths and weaknesses of your solutions

-Justify your decisions

-Become self-directed and self- motivated to produce quality work

-Boost confidence and pride

slide46

• Effectiveness - judging how well one did in meeting the goals of the information problem-solving process

-Compare requirements to results

-Check appropriateness and accuracy of information

-Judge how well solution is organized

-Rate quality of final product compared to potential

-Judge quality of product to predefined standard

slide47

• Efficiency - saving time and effort in the process, doing as well as possible with as little time and effort as possible

-Recognize how you learn, process information and solve problems

-Keep log of problem-solving activities

-Reflect on sequence of events and judge effort and time involved

-Review frustrations and barriers encountered

-Rate abilities to perform activities

slide48
