Title: Learning with the WWW: What does the research show


1
Learning with the WWW What does the research
show?
  • Andrea Peach
  • Georgetown College

2
Topics
  • How the web is used in K-12 education.
  • What the research shows about using Educational
    Technology in general and the web specifically in
    K-12 education.

3
Method
  • Present the research summary findings
  • Show examples
  • Discussion

4
How is the web used in education?
5
Instructional Delivery
  • Learning issues in web-based instructional
    delivery are similar to issues in hypermedia
    research

6
Hypertext/Hypermedia
  • Hypertext is essentially non-sequential writing
    (Nelson 1987)
  • Nodes of information linked together, typically
    with some type of structure.
  • Addition of media (audio, video, graphics) to
    hypertext is called hypermedia

7
The web is one big hypermedia production!!!!
  • A web page a hypermedia node.
  • Web pages are linked to other nodes.
  • Web pages can contain text, graphics, audio or
    video

8
The shape of web-based instruction
9
Structure of Hypermedia Learning Systems
  • By definition, hypermedia is non-linear.
  • The structure of the actual hypermedia content,
    however, is determined by the creator of the
    content.
  • Some web sites are highly structured, many times
    almost linear in nature.

10
Linear web-based learning
  • The Biology Project -- The University of Arizona
    http//www.biology.arizona.edu/biochemistry/tutori
    als/chemistry/main.html
  • The Interactive frog Dissection -

  • Math, Baseball the San Francisco Giants! -

11
Non-linear
  • StarChild --http//starchild.gsfc.nasa.gov/docs/St
    arChild/StarChild.html
  • Microbe Zoo - http//commtechlab.msu.edu/sites/dlc
    -me/zoo/
  • The Valley of the Shadows - http//jefferson.villa
    ge.virginia.edu/vshadow2/

12
Differences between linear and non-linear web
pages
  • Entry Points
  • Linear has a definite start
  • Non-linear has multiple possibilities
  • Exit Points
  • Linear has definite end
  • Non-linear has multiple possibilities
  • Learning Paths
  • Linear has prescribed path
  • Non-linear has more choice (Slatin 1991)

13
Non-linear learning may also..
  • Assist learners in forming relationships between
    information, thus...
  • aiding in encoding and recalling information
    (Hannifin Rieber 1989 Jacobson Spiro, 1994)
  • developing non-linear thinking and reasoning
    skills (Kearsley, 1988)
  • aiding in making the transition from novice to
    expert (Jacobson Spiro, 1994)

14
Examples
  • Linear - The Interactive frog Dissection -
    http//teach.virginia.edu/go/frog
  • Non-linear - Microbe Zoo - http//commtechlab.msu.
    edu/sites/dlc-me/zoo/

15
What are problems with non-linear sites?
Cognitive overload (Conklin, 1987)
16
Lets look at the research ...
  • First of all, understand that there is very
    little conclusive research on using hypermedia in
    instruction.
  • But, there are theories that have been explored
    and, to some extent, supported.

17
Cognitive Flexibility Theory (Spiro et al. 1987)
  • Can serve as a guide to determining learning and
    learners that may be best suited to specific
    types of technology-based learning environments
    (Jacobson Spiro, 1994)

18
Cognitive Flexibility Theory - Linear
  • Beginning learners
  • Well structured content
  • Simple knowledge domain
  • Example - Math, Baseball the San Francisco
    Giants! - http//www.kn.pacbell.com/wired/baseball
    /

19
Cognitive Flexibility Theory --Non-linear
  • Advanced learning
  • Transfer/application learning goals
  • Complex and ill-structured domains
  • Example - The Valley of the Shadows -
    http//jefferson.village.virginia.edu/vshadow2/

20
Research Support for CFT
  • Beginning learners may have more success with
    linear instruction (Fugitt 1991 Peach 1996
    Jacobson 1991 Tsai 1989 Mohageg 1992)
  • High ability, high knowledge level, field
    independent, highly motivated students did better
    with non-linear (McGrath 1992 Klappenberger
    1990 Gray 1990 Marchionini, Lin, and Dwiggins,
    1990 Gillingham, 1992 Sextro, Brungardt, and
    Byars 1990)
  • Jacobson used drill practice, similar to
    linear instruction

21
Other factors that may affect learning with
non-linear web sites
  • Orienting devices such as
  • providing instructional advice (Klader 1993 Lee
    1992 Barba and Merchant 1990)
  • content and navigation maps (Barba 1993)
  • interface and design (Liang 1989 Carter 1992
    Welsh, Murphy, Duffy Goodrum 1992)

22
Other factors that may affect learning with
non-linear web sites
  • Individual learning characteristics, such as
  • prior knowledge of the content (McGrath 1992)
  • prior general computer experience (Peach 1996)
  • prior experience with using the web (hypermedia)
    (Peach 1996)
  • external motivation (Sextro, Brungardt and Byars
    1990)

23
Problems with research studies
  • Short treatment times (Reeves 1993 Clark 1989)
  • Inappropriate design (Waterworth and Chignell
    1989)
  • Almost all studies measure low-order learning,
    not high-order learning (Peach 1996)

24
Conclusions
  • Know the students that will be using the web
    site.
  • Beginning, intermediate or advanced learners?
  • Do they have prior experience with using the web?
  • Are they motivated to learn?

25
Conclusions
  • Analyze the web site that you plan to use..
  • Linear or non-linear?
  • Does it contain learning aids?
  • Is the content appropriate for the grade level?
  • Is the site easy or difficult to navigate?

26
Conclusions
  • Observe the students while they use the web site
  • make sure they dont surf instead of learn
  • help with cognitive overload and disorientation
    problems
  • Evaluate frequently
