Digital Immigrant instructors, who speak an
outdated language (that of the pre-digital age),
are struggling to teach a population that speaks
an entirely new language.

1. Translating a question into a query

• Starts with a question or a problem to solve.
• Task Translate a natural language question or
  statement into language that is understood by a
  search engine.
• Search engines differ in how they process
  queries, but for the most part, what works on one
  big commercial search engine tends to work on the
  others.
• Search engines perform a variety of literal
  matching functions with Boolean and special
  operators.

1. Translating a question into a query

• Which of the following is the most effective
  query for 'find the top speed of earth's fastest
  animal'?
• speed fastest animal
• what is earths fastest animal
• top speed earths fastest animal

• Translating a question into a query
• Research Findings (IMSA second semester
  sophomores)

1

• 36 recognized the optimal query from a list of
  three queries. Only 14 of incoming 9th graders
  at a local high school identified the optimal
  query.
• 31 grasped that search engines perform literal
  matching.
• 17 regularly use natural language queries.
• 12 misinterpreted the research question.

8
2. Selecting an adequate database

• This failure occurs before submitting the first
  query.
• Task Predict where expert information may be
  found.
• No search engine performs a live Internet search
  when you submit a query. (Otherwise, how could
  they come back with a page thats not found?)
• That which is stored in one search engines
  database is invisible to another search engine
  (also called Enterprise Data)

2. Selecting a good database Research Findings
(anecdotes from teachers)
1

• When permitted, most students prefer to Google

10
3. Recognizing relevant information

• This failure occurs when a student looks at the
  results returned by a search engine.
• Task Match findings with expectations, evaluate
  relevance
• Information on the Internet is not always found
  in predictable places.
• Computers are made for speed, which encourages
  haste.
• Hyperlinks and graphics can be distracting.

3. Recognizing relevant information Research
Findings (junior honors students)
1

• 36 were able to identify web pages that contain
  supporting research facts from a selection of
  three pages.
• 25 -- same task, middle school students

12
4. Finding better keywords

• This failure occurs throughout the search
  process before the initial query is submitted
  and as students look at the results returned by a
  search engine.
• Task Select and try increasingly specific
  keywords
• Frequently, effective keywords go unnoticed in
  snippets.
• Our claim Effective searching depends on keyword
  selection more than any other factor.

4. Finding better keywords Research Findings
(high school)
1

• 14 of IMSA sophomores used alternate keywords
  when searching.
• 7 of junior honors students chose effective
  alternate words to find information.

14
5. Evaluating credibility

• This failure occurs after information has been
  located.
• Task Check the credibility of information,
  authorship
• Typically, students forego this decision
  altogether and uncritically accept whatever
  information they found.
• Depending on which database the information was
  taken from, information may be unedited,
  unendorsed and inaccurate.
• Special operators (link) makes external
  evaluation easier.

5. Evaluating credibility Research Findings (high
school honors students)
1

• 0 were able to use special operators to evaluate
  the credibility of a web page.

What You Can Do To Help
Question to query checklist
1

• How many key concepts (important ideas) are found
  in the question?
• How many key concepts will I search for?
• What keywords are probably effective as is?
• For which concepts are more effective keywords
  probably needed?
• Are there hyponyms or professional language for
  any of the intermediate words?
• Are there words that have multiple meanings?
• Did I use any stop words or clutter words?
• Did I spell the words correctly?
• Did I put the most important words first?

What You Can Do To Help
Choose the best database
1

• What person would know the answer I am looking
  for?
• Where would I find that expert?
• Use Google/Yahoo to get there and then use the
  proprietary search engine to go farther.
• To find a relevant database use keywords like
  DATABASE, ARCHIVE, INFORMATION in combination
  with subject matter.
• Use Beaucoup.com to search for databases.

Recognize relevant information
1

• Practice reading snippets Snippet Sleuth
• Use the FIND Command
• Challenge Find the name of the poem that
  contains the line to tell just what it knows

22
What You Can Do To Help
Find better keywords
1

• Practice with snippets and thesaurus Soccer
  Challenge II
• Practice with snippets Soccer Challenge III,

What You Can Do To Help
Verify Credibility
1

• External validation of content Links to this
  site from other sites
• Technique - link http//www.edutopia.org
• Practice using the link operator Evaluation
  Challenges

24
How, When and Where can skills be taught?

• Performance skills require hands-on practice
• Search challenges
• Interactive tutorials
• MicroModules (example FIND COMMAND)
• Search Wizard
• When and Where can these skills be taught?
• In the context of research paper preparation
• Computer lab and non-digital applications
