purpose of the site?

CARRDSS
• A method for evaluating Web sites
• What does CARRDSS stand for?
– Credibility
– Accuracy
– Reliability
– Relevance
– Date
– Sources
– Scope
Let’s Practice!
• The following activities are taken from the
Web site CARRDSS Website Evaluation.
CARRDSS
CREDIBILITY : Who is the
author? What are his or her
credentials?
CARRDSS
• Go to the Cyberbullying
Research Center
• Find two pieced of evidence
that show how credible the
people who add the
information are.
CARRDSS
ACCURACY: Can facts,
statistics, or other information
be verified through other
sources? Based on your
knowledge, does the
information seem accurate?
CARRDSS
•
Go to Choose Responsibility.
•
Mothers Against Drunk Driving cites research on
their website that says that an estimated 25,000
lives have been saved by raising the Minimum Legal
Drinking Age to 21 in the United States.
•
Open the site above and skim the page to find the
section that addresses this statistic.
•
Write down at least one reason that one of the
sites gives to dispute this idea. Do you find the
argument convincing? Why or why not?
•
Hint: Use the Ctrl and F keys together to get a
search box for finding the word traffic on the page.
CARRDSS
RELIABILITY: Does the
source present a particular
view or bias?
CARRDSS
• Take a look at these three sites to see the
difference in point of view and purpose:
Site #1 (sell: a site from the beef industry)
Site #2 (inform: a site from Harvard
School of Public Health)
Site #3 (persuade: a site from People for
the Ethical Treatment of Animals)
You can detect bias in a site by paying to
attention to:
– strong/emotional language
– missing information
– misrepresenting other people's points of
view
CARRDSS
RELEVANCE: Does this
information directly support
my hypothesis/thesis or help
to answer my question?
CARRDSS
• Does this Web site below
answer the question: Should
we lower the minimum legal
drinking age to under 21?
– Alcohol Problems and
Solutions
• Does this site have answers
to your question?
CARRDSS
DATE: When was this
information created? When
was it revised? Are these dates
meaningful in terms of the
subject matter?
CARRDSS
• When was this information
last updated in this identity
theft Web site?
• Privacy Rights Clearinghouse
CARRDSS
SOURCES BEHIND THE
TEXT: Did the author use
reliable, credible sources?
CARRDSS
• Where did this Web site get
its information from about
over population?
• Let’s look up these sources.
Do you still trust them?
CARRDSS
SCOPE: Does this source
address my
hypothesis/thesis/question in
a comprehensive or peripheral
way? Is it a scholarly or
popular treatment?
CARRDSS
• Who is the audience for each
site below?

What are Search Engines?
• Search engines are huge
databases of Web page files that
have been assembled
automatically by machine.
(From Bare Bones 101.)
• Merriam-Webster Online
dictionary defines search engine
as:
– computer software used to search
data (as text or a database) for
specified information
How do Search Engines Work?
• “Spiders” or “Robots (bots)” crawl the Web to
find your information.
• Web masters must tell the search engine what
their Webpage contains or the “spiders” will
not find their page.
• Search engines do not search the Web as it
currently exists and only searches part of the
Web.
Pros of Search Engines
• You can get a large number of public pages
available on the Web.
• Currently the best way to conduct a search.
Cons of Search Engines
• You get too many hits!
– What you are searching for could be:
• The only time that word is in the document or
Webpage.
• Some engines read the Webpage’s URL (address.)
• Some engines will look at the html codes!
– What is html????
Are Search Engines all the Same?
• Yes
– They all use software.
• No, they find information in
different ways.
– The amount of places they
look for information from.
– The speed at which they look
for information.
– They have different search
options.
Are Search Engines all the Same?
– How they rank the WebPages you are searching
for relevancy to the topic. They follow different
rules.
• Some search for the location and number of times your
topic is in the document.
• Check the headings and text near the top of the
document.
• How many times a link is clicked on.
• How many other Websites link to a Webpage.
Search Engines are Good for:
• Finding unique words, phrases or quotes.
• Getting lots of hits.
• Showing a wide range of responses to your
search.
Let’s see just how many hits we can get!
• Open up Internet Explorer.
– Search for bing and open it.
• Key: cat in the search box.
– How many hits do you get?
– Where is the search box now?
Next…….

• Key in cat in the search box.
– How many hits?
Next…..
• Click in the URL line, the address line.
– Key in yahoo.com
– In the search box, type in cat again.
