Computer Usage and Access Patterns of Actual and Potential LSAT Takers (CT-97-10)
by Susan M. Jenkins Samantha D. Holmes, University of Michigan
Executive Summary
As part of a larger study exploring the advisability and
feasibility of administering the Law School Admission Test (LSAT) by computer,
the Law School Admission Council (LSAC) is investigating the computer usage and
access patterns of actual and potential LSAT takers. Some previous computer
usage research indicates that systematic differences in computer usage,
comfort, and access by gender, race/ethnicity, and age may exist. However,
other research indicates that when basic computer skills—such as word
processing—are examined, differences across gender, race/ethnicity, and age are
nonexistent. Similarly, results from studies specifically focused on the use of
computerized tests suggest that if test formats are kept simple and test takers
have sufficient preparation time, there is little reason to expect that members
of any particular demographic group would be disadvantaged. Preliminary data collected by LSAC staff indicated that
there are few differences across demographic groups with regard to the use of
basic, Windows-based computer software. However, in order to determine whether
computerizing the LSAT might possibly create an undue burden to any group of
LSAT takers, definitions of computer usage and access needed to be refined. For
example, preliminary data indicated no significant differences across
demographic groups with regard to computer access. However, this general level
of data does not address specific issues such as where participants have
computer access and whether that access may be limited in ways that could
interfere with using the computer to prepare for a computerized LSAT. The five surveys used for this report included samples of
convenience, as well as representative samples of LSAT takers for a total of
2,836 participants. Because two of the survey projects were designed to include
sufficient numbers of racial/ethnic minority group members to allow statistical
comparisons, the racial/ethnic distribution in the final sample includes larger
percentages of members of racial/ethnic minority groups than are present in the
actual LSAT-taking population. The results of this study indicate that, as expected, more
than 85% of participants reported being at least somewhat comfortable using a
computer, using a computer at least once a week, and having at least weekly
access to a computer. With regard to specific types of computer usage and
location of computer access, there were some significant differences by
demographic group. By gender, there were no differences in either general or
specific types of computer usage or general levels of computer access. However,
with regard to location of access, men were significantly more likely to report
home computer access than were women. By race/ethnicity, there were no significant
differences across groups with regard to general computer comfort, although
there were small differences with regard to frequency of computer usage and
location of computer access. Black/African American and
Hispanic/Latino(a)/Chicano(a) respondents were slightly less frequent computer
users and were slightly less likely to report having home computer access than
were members of other racial/ethnic groups. By age, there were no differences
across groups with regard to general computer comfort or frequency of use,
although respondents over 40 years of age reported slightly less comfort using
Windows-based programs or a mouse to control screen features. With regard to
location of computer access, the only significant age-related difference was
that younger respondents were more likely to have computer access at school,
while older respondents were more likely to have access at work. Finally, by
student status, there were no differences in general computer comfort or
frequency of use. The only meaningful difference reported for specific kinds of
computer usage was that participants out of school for more than three
semesters were significantly more likely to be comfortable using the right
mouse button to control screen features than were current students or recent
graduates. Another difference was that while graduates were significantly more
likely than students to have computer access at work, students were
significantly more likely than graduates to have computer access at school and
at home. In summary, these data indicate that there are few overall
differences by demographic group with regard to computer comfort, computer
usage, and computer access. However, as there appear to be differences across
demographic groups related to specific types of computer usage and locations of
computer access, more work needs to be done to determine the size, nature, and
practical implications of these differences. For example, while there are
indications that test takers over 40 years of age—particularly women—may have
some barriers to computer usage, a larger sample needs to be surveyed before
generalizations can be made. In addition, because data from both volunteer
participants and those randomly sampled to provide representative data were
combined, care should be taken in generalizing these results to the LSAT-taking
population as a whole. |
