Before sharing your LSSSE results school wide,
it’s very important to become familiar with
the nature of the data and “story line”
of your school’s performance. Here are some
things to consider.
Check the Representativeness of Your Respondents
Even though the survey was administered online
to all J.D. students at your school, an essential
early step is to check to see that the characteristics
of students responding to LSSSE are comparable
on various biographical characteristics to other
information about students that is available in
your school.
Interpret Results for 4L Students
with Caution
Of the 13,197 student respondents, only 249 are
4L students. Most LSSSE schools have either none
(60%) or very few 4L respondents (7%), while one-third
(33%) of schools had at least ten 4Ls complete
the survey. Because the number of respondents
is relatively small, caution should be used in
interpreting these results.
Look Carefully at Items with Large Effect
Sizes
In the Means Comparison Report, asterisks
(*) mark those survey items where your students’
responses differ at a statistically significant
level from students at other LSSSE 2004 law schools.
Because of the large number of students surveyed,
we employ several different statistical significance
thresholds to reduce the probability that the
differences noted are due to chance (p < .05,
p < .01, and p < .001).
Even
though the differences reported are highly reliable
and statistically significant, the actual magnitude
of some item score differences may be trivial.
That is, they may not represent a behavior or
dimension of the law school student experience
at your institution that is qualitatively different
from that of students at other law schools. For
this reason we also report the effect size associated
with those item comparisons that are statistically
significant. The effect size represents the magnitude
of the discrepancy in the student or school behavior
the item measures. When the effect size is large,
or a pattern of small or moderate effect sizes
exists, it’s likely that the quality of
the student experience is appreciably different
and, therefore, may be of practical as well as
statistical significance with regard to the respective
area of student engagement.
Finding
large effect sizes is not that common in most
areas of non-experimental educational and social
science research. So, if your results include
some medium or large effects, something may be
going on that warrants immediate attention, especially
if other empirical or anecdotal information corroborate
the LSSSE data. Here are some general guidelines
for determining the relative importance of a Cohen’s
d effect size:
.20
is a small effect
.50 is a medium effect
.80 is a large effect
Look for Patterns
in Item Differences
In addition to focusing on items with medium
to large effect sizes, look for patterns in your
students’ responses. For example, are your
students consistently above or below the mean
of the LSSSE 2004 group in one or more areas of
engagement? Are the differences explainable, perhaps
a function of your law school’s location,
the institutional mission, or certain student
characteristics?
Also,
don’t rely exclusively on statistical significance
tests to identify areas that warrant attention.
A consistent pattern of scoring above the mean,
even though all the items may not reach statistical
significance, may indicate your school is doing
many of the right things in terms of good educational
practice. At the same time, some schools have
very high expectations for student engagement
and may fall short of their own aspirations even
though comparisons with other LSSSE schools are
favorable.
Standards of Comparison
LSSSE data serve a diagnostic function by identifying
school strengths and weaknesses in terms of effective
educational practices. Comparisons with aggregated
data from the other LSSSE 2004 schools help reveal
aspects of school and student performance not
readily available from other sources.
There
are two basic approaches that many schools use
to think about their results. One or both may
be appropriate, depending on your institution’s
situation.
Normative
Approach
The
normative approach compares your students’
responses to those of students at the other 41
law schools in LSSSE 2004. This information is
readily available from the Means Comparison Report.
Breaking down the information into subgroups or
engagement topics may be a way of stimulating
faculty interest and discussion in the findings.
Criterion
Approach
A
second way of looking at your results is a criterion-referenced
approach, whereby you compare your law school’s
performance against a predetermined value or level
that you and your colleagues deem appropriate
for your students, given your school mission,
size, curricular offerings, selectivity, demographics,
and so forth. |
