Review: What is the Internet?
• Computers connected to each other around the world
• Accessible to billions of people worldwide
• Offers many free services including:
- Email
- Chatting
- World Wide Web
• The Internet is also called “The Net” or being “online”
3
Review: Browsers
• Computer software that lets you read information on
the Internet.
• Most popular browser is Microsoft’s Internet Explorer.
– Great alternatives include Mozilla Firefox and Opera.
• Use “Website addresses” to find information
– E.g. www.halifaxpubliclibraries.ca
4
Lesson 1: The Website Address
http://www.gov.ns.ca/premier/
Tells the
browser to
“Use the
Web”
The “Website” address, also
known as the website’s “Home
Page.”
The “Premier” page
on the website
5
Lesson 1: The Next Step
• Q: How do I find information on the Internet if I do not
know the web address?
• A1: Click links until a page leads you to the
information you want.
• A2: Use an Internet Search Engine.
6
Lesson 1: Using Links
• Website use “links” to lead people from one page to
another.
– To go to another page, you “click” (just once!) on the link.
– These links are generated by humans.
• When you put the mouse pointer [
turns into a hand [ ].
] over a link, it
• Links are usually bolded, underlined and/or have a
different colour than other text on a website.
– Sometimes pictures can be links too.
7
Lesson 1: “Websites” versus “Pages”
• Every website can have one or more pages
– The first page on a website is called “The Home Page” and usually
has pictures to help tell you where you are.
– To make it easy to get to the “Home Page” Websites:
• Make their logo link to the Home Page
• Or have a Link called “Home”
• A link can lead to:
– A page inside the website
– The homepage of another website
– A page inside another website.
8
Try This
• Go to www.cbc.ca
• Find the “links” on the page
– How can you tell something is a link?
– Do the pictures contain links as well? How do you know?
• Click on a link and see where it goes
– How can you get back to the cbc.ca page?
9
Lesson 1: Search Engines
• Display a list of websites based on words that are
typed into a search box (keywords).
• Display the most relevant websites first.
–

–
Pages with many “reliable” links show first.
Pages selected most often by other searches show higher.
Results are machine generated.
There will like be irrelevant results.
10
Lesson 1: Popular Search Engines
•
•
•
•
•
•
Google (about 49% of searches)
Yahoo (23.8%)
MSN (9.8%)
AOL Search (6.3%)
Ask (2.6%)
Others (8.5%)
11
Lesson 2: Searching with Google
Google Canada is just one
of the flavours of Google
This button takes you to
the first web page Google
returned for your query.
You will not see the other
search results at all.
Google Canada is also
available in French
12
Lesson 2: Keyword Searching
Enter your search
terms (keywords)
into the search box
13
Lesson 2: Interpreting Your Google Search Results
Each result has 3 details
1. Title of website
2. Text sample
3. Web address
A list of websites that have paid
to be included with the results
of your selected keywords
14
Lesson 2: Interpreting Your Google Search Results
Google also suggests more
refined results using
more keywords that are
related to similar subjects
Simple keywords can
return many search results
Google divides the results
into manageable sets of
pages for viewing
15
Lesson 2: Keyword Searches
• When searching for 1+ keywords, Google
automatically searches for all keywords entered into
the search box.
chicken soup
is the same as
chicken AND soup
16
Lesson 2: Finding Better Results
Reducing the Number of Results
1.
Use more descriptive keywords
Example:
chicken soup
vs.
spicy chicken soup recipe
17
Lesson 2: Finding Better Results
TRY THIS:
1. Search for soup recipe. How many results do you get?
2. Search for chicken soup recipe. How many results do
you get?
3. Search for spicy chicken soup recipe. How many
results do you get?

Lesson 2: Finding Better Results
Reducing the Number of Results
3.
Using a “-” in front of a keyword you can remove all
results with that search term.
(Note: There is NO space between the minus sign and
the search term.)
Example: halifax genealogy -virginia
22
Lesson 2: Finding Better Results
TRY THIS:
1. Search for halifax genealogy. How many results do you get?
2. Look at results on pages 1 and 2. Do you see any that relate to a
Halifax that isn’t in Nova Scotia?
3. Now search for halifax genealogy –virginia.
Google reads the search as “Look for ‘halifax genealogy’ but NOT
‘virginia’. How many results do you get?
That’s gotten rid of the results related to the Halifax in Virginia, but how
do we eliminate the results for Halifax, Yorkshire, England?
23
Lesson 2: Finding Better Results
TRY THIS (cont’d)
3. Search for halifax genealogy –virginia –yorkshire.
How many results do you get?
4. Search for halifax genealogy –virginia –yorkshire –
england. How many results do you get?

How can you change your search to filter out Halifax,
Australia?

Lesson 3: Finding Reliable Sites
• Not all web pages offer reliable information (but
neither do all books, magazines and newspapers)
– Be a critical web consumer!
– Some people like to talk about hobbies on their website, but are not
experts
– Search engines are pretty good at finding good information, but
they are not perfect
27
Lesson 3: Four Strategies
• Who is writing the information?
– Can you trust them to answer your question?
• Why are they writing the information?
• Is the information up to date?
• Does the site have any errors that you notice?
28
Lesson 3: Who is writing the information?
• Reliable sites usually identify who they are.
• Look for links to an “About” page
– the information should be specific and should include:
•
•
•
•
•
A name of someone responsible for the information
A description of what the organization or individual does
Where they are located and who they serve
Specific contact information
Names of executive members and their roles if it is an organization or
business
29
Try This
• Go to www.customerservicesummit.org

Is there any other information that helps you tell whether this is reliable or

30
Lesson 3: Why are they writing the information?
• Reliable websites usually make their purpose
obvious.
–
–
–
–
–
Education
Sales of products or services
Influence or inform you about a particular issue
Fun/games
Social interaction
31
Lesson 3: Look Out For. . .
• Lots of Advertisements
• Lots of Grammar and Spelling Errors
– Unreliable sites use spelling errors and bad grammar to keep
Google from recognizing them as unreliable. E.g.. “1vory Coast”
instead of “Ivory Coast.”
• “Facts” stated without a note about where they got it
– Experts say that 99 % of computer instructors are geniuses (Do you
believe me?).

33
Lesson 3: Is the Information Up-to-Date?
• Reliable websites usually
update their information
frequently and show when
they did it
• Look a date that shows how
up-to-date the site is
• Look for other signs as well:
– Old addresses in the contact
section
– News that happened long ago
– Links that are not working
