Sample
  • 263 valid responses were captured in the survey
    database.
  • Basic statistics for the data is summarized below
    for the significant groups.
  • Class Status
  • 127 freshman, 66 sophomore, 49 juniors, 16
    seniors
  • First Computer Use
  • 96 in elementary, 97 in middle school, 37 in high
    school, 33 in college.

Significant Data Findings
  • There were statistically significant difference
    found in two population groups.
  • The participants who classified themselves as
    freshman had significant difference with the
    other classifications.
  • There were also significant differences based on
    first computer use among participants.

PLS-Graph of Dissertation Model
  • The next three slides show the PLS-Graph analysis
    of all the participants.
  • Just the declared freshman participants.
  • Just the junior senior participants.

Explanation
  • The numbers in the middle of the arrows represent
    the contribution of each independent construct to
    the dependent constructs.
  • The number below the dependent constructs is the
    percent of variation of that construct explained
    by the model.

Discussion
  • The dissertation model supports five of the six
    hypotheses as discussed in the slides to follow.
  • This whole process has been extremely rewarding
    as it opened a new world of behavioral research
    for this researcher.
  • Although this is a very narrow topic the area has
    many problems to analyze.

18
  • This experience has opened the area of web based
    survey that will be highly valuable for future
    research.
  • The statistically analysis and PLS-Graph
    knowledge gained will benefit both the student
    and his research in the future.
  • The process has changed the way the research
    thinks about addressing a problem.
  • The learning experience is about the journey not
    the destination.

19
University students, in this environment, accept
the tablet PC.
  • All participant groups have positive behavioral
    intent and use behavior and most construct have a
    positive contribution to the dependent variables.
  • Group Behavioral Intent Use behavior
  • --------------------------------------------------
    ---------
  • All 55 11
  • Freshman 63 22
  • Upper Class 49 7

20
The Unified Theory of Acceptance and Use of
Technology (UTAUT) does predict the successful
acceptance of the Tablet PC.
  • All constructs used in UTAUT have a positive
    correlation to behavioral intent.
  • Anxiety (- 7) is not part of UTAUT it was added
    to this study to support investigative vigor with
    attitude toward using technology (47) and self
    efficacy (12).

21
The constructs of the UTAUT will demonstrate an
effect on user acceptance of the Tablet PC.
  • Supported by the same data as the previous
    alternative hypothesis.

22
Computer self efficacy does have an impact
students acceptance of the Tablet PC.
  • The dissertation model re-introduced this
    construct and found that in the research
    environment this variable does impact acceptance.
  • Group Self Efficacy Contribution
  • --------------------------------------------------
    ---------
  • All 12
  • Freshman 10
  • Upper Class minus 2

23
  • The contribution of self efficacy will be studied
    more in depth in subsequent research with a K12
    one-on-one study that will be conducted in South
    Dakota with 30 pilot schools.

24
Anxiety about computer use does have an impact on
students acceptance of the Tablet PC.
  • The negative contribution of anxiety indicate
    that there is not a contribution to the dependent
    construct behavioral intent.
  • Contribution is -7 for the whole population and
    -12 for both the freshman and upper class groups.

25
Students use of the Tablet PC does impact
students acceptance of the device.
  • Initially I thought that the positive outcome of
    the dissertation model indicated support for this
    statement, but after learning more about the
    PLS-Graph tool I learned that you could reverse
    the arrow of effect and when I did that for use
    behavior I found that it did not have a positive
    contribution to behavioral intent.

26
The influence of use behavior
  • Reversal of the link between the two dependent
    constructs indicated in the dissertation model
    that use does not contribute to behavioral
    intent.
  • The freshman and upper classmen model does
    indicate a contribution at 7 16 percent
    respectively.
  • This phenomena should be further studied.

27
Future Research
  • The research for this dissertation has opened my
    perceptions of all the possible applications of
    adoption research.
  • There are many opportunities to pursue this type
    of behavioral research and grant opportunities
    should be available.
  • Initially I will be collaborating with Dr. Hawkes
    on the K12 project in South Dakota and publishing
    the dissertation results with Dr. El-Gayar at the
    DSI meeting in San Antonio this fall.

28
  • With the time now, and knowledge, now available
    to me I will be pursuing grant opportunities and
    plan to be active in publishing the findings of
    my research in the next three years.
  • The K12 study with have two data samples, one
    before the pilot study begins and a follow-up
    survey after one year of use in the K12 pilot of
    thirty schools. Approximately 250 teachers will
    be involved and we hope for more than 50
    participation in the survey.

29
Concluding remarks
  • During the dissertation process I have learned
    much more than I thought I might.
  • Technology acceptance is fundamentally about
    about two features of technology ease of use and
    usefulness. Initially they seem the same but they
    are not!

30
  • Ease of use is an interface issue and can be
    changed pretty easily.
  • Usefulness is based on company requirements and
    is very hard to change once a project gets to the
    users.
  • The perception of these characteristics can make
    or break a project.
  • Measurement of these before project
    implementation can alert the organization to
    possible problems that can be averted.

31
  • These are multistable preceptions users can
    rarely recognize both but project success
    requires both so management needs to be aware
    before it is too late!
