  • More and more Americans go online for news.
  • Nearly 20 of Americans sought election news
    online during
  • the presidential election in 2000, compared
    to lt 5 in 1996.
  • Over 1/3 of adults under 30 years old used the
    Web as a source of
  • election news.
  • A survey showed that
  • 1/3 of Americans get news online at least once
    per week
  • 15 get online news every day
  • half of adults younger than 30 years of age
    get online
  • news at least once per week.

Decline in newspaper readership, particularly
prominent among young Americans.

  • The differences between Print and Online News
  • eg, The New York Times and The New York Times on
    the Web
  • Content differences are relatively small, rather
    a difference in
  • overall structure and organization
  • newspaper most important story at the top of
    the front page
  • online newspaper
  • - only the top few stories represent with
    more than a simple text
  • headline on home page
  • - other stories are organized by topic
    area, ranking of the stories
  • depends on recency
  • - use of story index
  • Online newspapers use hyperlinks

4
  • Effects produced by the difference in structure
    and organization between Print and Online News
  • Readers of The New York Times on the Web were
    less likely to
  • recall public affairs information
  • Users of The New York Times on the Web had more
    structured free
  • recall.
  • Users of print New York Times had overall
    greater free recall of the
  • news stories they read.

Difference in knowledge structure is caused by
the use of story index of the online Times
compared to the print Times.
5
  • Effects produced by the difference in structure
    and organization between Print and Online News
  • Hyperlinks between stories provided in some
    online information
  • sites may also serve to improve knowledge
    structure because they
  • communicate to readers how the news of the
    day, or the week, fits
  • into a larger picture.

6
  • Purposes of the Research Study
  • How best to design online news sites to encourage
    learning?
  • What features of online news may enhance or
    inhibit learning about public affairs?
  • What exactly is learned online simple
    disconnected facts or an interconnected picture
    of the events that together represent public
    affairs?
  • To compare online news sites that employ in-text
    hyperlinks to those with articles that simply
    mirror traditional print newspaper articles
    without hyperlinks between stories

7
  • Knowledge Content and Structure
  • Many common theories of human information
    processing posit
  • that memory is constructed of various nodes
    that are connected
  • to one another through links.
  • Most scholars agree that knowledge is not simply
    the recall of
  • recognition of simple facts.
  • Some educational psychologists distinguished
    between three
  • forms of knowledge
  • Declarative Knowledge the act of being aware
    of something or knowing
  • that it exists. It is divided two forms
    content and structure.
  • Procedural Knowledge refers to knowledge in
    use or the application of
  • declarative knowledge.
  • Structural Knowledge it mediates the
    translation of declarative knowledge
  • into procedural knowledge and facilitates
    the application of procedural
  • knowledge. Structural knowledge is the
    knowledge of how concepts within
  • a domain are interrelated.

8
  • Factual knowledge the content of declarative
    knowledge. It is the
  • potentially disconnected tidbits of
    information represented by the
  • nodes in human memory.
  • Knowledge Structure refers to the manner in
    which these nodes
  • are organized or related in memory the
    structure of declarative
  • knowledge.
  • The research focus on the assessment of
    Knowledge Structure
  • Density (KSD) - the simple density or number
    of interconnections
  • across concepts within a domain of memory

9
  • Learning from Hyperlinked vs Non-Hyperlinked News
  • Do individual learn more from hyperlinked or
    non-hyperlinked online news sites?
  • Do hyperlinked and non-hyperlinked online news
    sites lead to differences in information
    processing?
  • Are there differences in the types of knowledge
    obtained from hyperlinked vs non-hyperlinked
    online news sites?

10
  • Hypothesis
  • Based on the notion of structural isomorphism,
    cognitive elaboration should be encouraged more
    by a linked than unlinked online news site.
  • H1 Elaboration will be greater in the linked
    news condition than the unlinked news condition.
  • Linked news could present cognitive difficulties
    for users disorientation, therefore, news sites
    with numerous links between articles should
    generate disorientation than an unlinked news
    site.
  • H2 Disorientation will be greater in the linked
    news condition than the unlinked news condition.

11
  • Linked web designs may produce lower levels of
    factual knowledge than the unlinked web designs.
  • H3 Factual knowledge will be lower in the linked
    news condition
  • than the unlinked news condition.
  • In-text links should encourage users to consider
    the interrelationships among issues covered in
    the news and thus to recognize more
    interconnections than those exposed to a site
    without the hyperlinks
  • H4 Knowledge Structure Density (KSD) will be
    greater in the linked news condition than in the
    unlinked news condition.

12
  • Elaboration should have positive influence on all
    forms of knowledge.
  • H5a Elaboration will be positively related to
    factual knowledge
  • H5b Elaboration will be positively related to
    KSD
  • Disorientation may inhibit gains in both factual
    knowledge and KSD.
  • H6a Disorientation will be negatively related to
    factual knowledge
  • H6b Disorientation will be negatively related to
    KSD

13
  • Method
  • Participants
  • Upper-level undergraduate students
  • Average age around 22
  • 60 majors in journalism and communication
  • A median 3 hours per week of Web use
  • Procedures
  • Randomly assigned to one of the three conditions
  • A control group
  • A linked online newspaper group
  • An unlinked online newspaper group

14
  • Procedures
  • Participants in the two experimental conditions
    were exposed to an online newspaper that closely
    resembled The New York Times on the Web.

  • Homepage and 25 articles from the
  • online Times were downloaded and
  • modified to serve as the stimulus for the
  • study.
  • Advertisements were eliminated from
  • the home page and all articles.
  • Much of the content of the home page
  • were removed.
  • Layout of the home page and the New
  • York Times label were preserved.

15
Procedures The articles selected were based on
the following systematic criteria a. any dates
appearing in the articles could be modified so
that the stories would appear recent b.
most articles could be considered to be at least
somewhat related to at least one other
article and thus can apply hyperlinks between
articles c. articles represented a reasonable
cross-section of topics from a normal day of
news d. no story would be so time-sensitive that
a typical participant could specifically
remember its occurrence in the weeks prior to the
experiment
16
  • Procedures
  • Unlinked condition stories could only be
    directly accessed through a story index on the
    home page
  • Linked condition not only access to index link,
    but also access between many stories through
    in-text hyperlinks
  • Participants in the two experimental group were
    asked to read the online newspaper in a
    supervised computer laboratory for 30 minutes.
  • Post-test questionnaire were administered to the
    experimental
  • groups.

17
  • Results
  • No significant difference in elaboration between
    participants in the unlinked news condition
    compared to those in linked news condition. H1
    was not supported.
  • No significant difference in disorientation
    between participants in the linked news condition
    compared to those in the unlinked news condition.
    H2 was not supported.
  • Subjects in the unlinked news condition scored
    significantly higher on the test of factual
    knowledge than those in the linked news
    condition. H3 was supported.
  • Density was greater among those linked condition
    than the unlinked condition. H4 was supported.

18
  • Elaboration was not positively related to factual
    public affairs. H5a was not supported.
  • Elaboration was positively related to the
    density of public affairs knowledge. H5b was
    supported.
  • 6. Disorientation was not negatively related to
    both factual knowledge and KSD. H6a and H6b were
    not supported.

19
  • Findings
  • A substantial difference between the effects
    observed on factual content and the density of
    knowledge structure regarding public affairs.
  • The use of in-text hyperlinks can have beneficial
    effects depending on the type of knowledge
    measured.
  • Density appears to be more likely to be
    influenced by cognitive elaboration on news
    content than is simple factual knowledge.
  • A nonsignificant tendency for disorientation to
    be more detrimental to density than factual
    knowledge.
  • Absence of an association between elaboration and
    factual knowledge.

20
  • Conclusion
  • What can designers of online news sites gain from
    these findings?
  • If the goal is to communicate basic factual
    information, links should be avoided.
  • Links seem to benefit those who commonly use the
    Web.
  • These experienced users would be able to take
    advantage of the linking structure for forming
    impressions of related issues.
  • Learning disconnected facts is greater among
    print or unlinked sources.
