Five Things Digital Natives Cannot Do (And What
You Can Do To Help) Carl Heine, Ph.D. Illinois
Mathematics and Science Academy
2
Translating a question into a query
Choosing the best database
Verifying the credibility of information
Finding better keywords
Recognizing information thats relevant
3
What digital natives dont do well What they tend to do instead
Turn a question into a query Rush ahead toward an answer, either grabbing the whole question as is or missing an important part of it
Choose the right database Enter words or phrases into Google
Recognize information when they find it Rush past important information and clues, continue to browse
Find better keywords Stick with their original words and browse
Verify the credibility of information Accept what they find at face value, hoping somewhere in the information there is an answer

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outdated language (that of the pre-digital age),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

1
7
  • 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 17 of seniors 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
(IMSA second semester sophomores)
1
  • 90 search with Google more than half of the
    time.
  • 32 use Google exclusively.

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 find.
  • 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
1
  • 33 of Illinois schools report having a
    curriculum method for teaching students to
    evaluate online resources
  • 0 of junior honors students 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
  1. How many key concepts (important ideas) are found
    in the question?
  2. How many key concepts will I search for?
  3. What keywords are probably effective as is?
  4. For which concepts are more effective keywords
    probably needed?
  5. Are there hyponyms or professional language for
    any of the intermediate words?
  6. Are there words that have multiple meanings?
  7. Did I use any stop words or clutter words?
  8. Did I spell the words correctly?
  9. Did I put the most important words first?

What You Can Do To Help
Choose the best database
1
  1. What person would know the answer I am looking
    for?
  2. Where would I find that expert?
  3. Use Google/Yahoo to get there and then use the
    proprietary search engine to go farther.
  4. To find a relevant database use keywords like
    DATABASE, ARCHIVE, INFORMATION in combination
    with subject matter.

music for only one motion picture. What is the
name of the movie?

How, When and Where can skills be taught?
  • Performance skills require hands-on practice
  • Search challenges (example Kermit)
  • Interactive tutorials (example Keyword
    Challenges)
  • MicroModules (example FIND COMMAND)
  • Search Wizard (advanced searching with help)
  • When and Where can these skills be taught?
  • In the context of research paper preparation
  • Library and research orientation
  • Computer lab and non-digital applications
