4Sample
- 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.
5Graphical Representation
6Significant 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.

10PLS-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.
11All participants
12Explanation
- 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.

17Discussion
- 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.
19University 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
20The 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).
21The 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.
22Computer 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.
24Anxiety 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.
25Students 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.
26The 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.
27Future 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.
29Concluding 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!
