2The Data Measurement
- Each student who visits a prefect session is
counted on a sign-in sheet. - Prefects who turn in these attendance records
(usually about 50-70 of prefects, but its hard
to be sure without looking at the actual numbers
of sessions that meet each term) add their data
to an ever-growing database that measures
students attendance at prefect sessions. - Along with a students attendance record, we
record the students gender, class year, major,
and whether or not the student attended the first
or second session in any given class.

4Major Findings
- Data on 59 classes--involving 38 prefects, 33
professors, and about 1,481 students--have been
collected and analyzed. - 948 students (64.21 of students taking classes
with prefects) have attended a prefect session at
least once from 2004 to 2006. - The average student who attended a prefect
session for a class attended 4.27 sessions for
that class. - Overall, from 2004 to 2006, there were 6,270
visits to prefect sessions. This does not
include one-on-one tutoring sessions, nor does it
include the many visits to the sessions of
prefects who did not turn in their attendance
records.
5By Academic Department
- 51.57 of biology students attended prefect
sessions, available in both Biology 125 and
Biology 126. - 65.62 of chemistry students attended sessions,
in Chemistry 123, 128, 230, 233, and 234. - 75.58 of computer science students attended
sessions, in Computer Science 117 and 127. - 70.20 of economics students attended sessions,
in Economics 110 and 111. - 67.42 of psychology students attended sessions
in Psychology 110 and 124.
6Gender Breakdown- Men
- 56.62 of men who had the resource available
attended at least one prefect session. - 18.51 of men attended at least 31 (or five) of
their classes prefect sessions. - 4.36 of men attended at least 63 (or ten) of
their classes prefect sessions. - 17.15 of men attended their classes first
and/or second session.
7Gender Breakdown- Men
- Men were 3.56 more likely to attend a prefect
session led by a female prefect. - They were 7.90 more likely to attend 31 (or
five) of prefect sessions if sessions were led by
a female prefect. - Men were 3.86 more likely to attend 63 (or ten)
of prefect sessions if sessions were led by a
female prefect. - However, men were 1.11 more likely to attend the
first or second session if the sessions were led
by a male prefect.
8Gender Breakdown- Men
9Gender Breakdown- Women
- 69.13 of women who had the resource available
attended at least one prefect session. - 30.52 of women attended at least 31 (or five)
of available sessions. - 9.32 of women attended at least 63 (or ten) of
available sessions. - 30.96 of women attended the first or second
session offered.
10Gender Breakdown- Women
- Women were 12.58 more likely to attend a session
led by a male prefect. - They were 18.66 more likely to attend 31 (or
five) of sessions if sessions were led by a male
prefect. - Women were 16.59 more likely to attend 63 (or
ten) of sessions if sessions were led by a male
prefect. - They were 22.91 more likely to attend the first
and/or second session if they were led by a male
prefect.
11Gender Breakdown- Women
12Gender and Attendance- Overall Trends
- Of the 59 classes for which data were available,
30 (or 50.85) had male prefects and 29 (or
49.15) had female prefects. - Overall, students were 8.43 more likely to
attend a prefect session led by a prefect of the
opposite sex. - They were 14.35 more likely to attend 31 of
sessions, 12.24 more likely to attend 63 of
sessions and 13.89 more likely to attend the
first or second session when the sessions were
led by a prefect of the opposite sex. - This trend is much more apparent with women,
although it is visible with men as well.
13Gender and Attendance- Overall Trends
14More Questions to be Answered
- First impressions Why were men more likely to
attend the first few sessions led by male
prefects, but more likely to continue attending
sessions when they were led by women? - Survey Suggestion Do students consciously
choose to attend more sessions led by a prefect
of the opposite sex? - Gender Stereotypes More men tend to prefect for
economics classes, and more women tend to prefect
for psychology classes. Is it possible that male
students simply feel less secure about their
knowledge in psychology (a less stereotypically
male discipline than economics) and therefore
attend more sessions in order to obtain the extra
help they think they need (and vice versa for
women in economics)?
15Sources of Error
- Because not all prefects turned in their sign-in
sheet data, everything measured paints an
incomplete picture of the reality of prefect
session attendance. - In analyzing these data, we worked closely with
the registrars office to gather class sizes and
gender breakdowns information that was essential
for our records and analysis. Although
communication between the Academic Support Center
and the registrars office has historically been
good, there have been a few errors or
miscommunications caught, and there could
potentially be more. - Lately, there have been more and more data that
do not make sense, cannot be true, and remain
unexplained. For example, according to the
prefects sign-in sheets and information
collected from the registrars office, there were
at least four classes in 2005-2006 in which more
women attended prefect sessions than were
actually registered for the class. The best way
to fix questionable data such as these is to be
sure that the class lists that the prefects use
are the same as the class lists that the
registrar has. - Some of the names on some of the sign-in sheets
are questionable. Did Francis Scott Key really
take Econ 111 at Carleton College?
16Suggestions for Improvement of Data
- The best and easiest way to ensure that our data
remain presentable and indicative of the actual
facts of the program is to improve communication
between students, prefects, professors, the
Academic Support Center and the registrars
office. - Professors need to supply students with a class
list, both before the class begins and after the
drop-add period ends. If this is an understood
expectation, not only will it make for cleaner
data, it will also improve prefect-professor
communication (because it will open channels and
allow for exchange of information at a vital time
in the term when students are thinking about
dropping the class), and it will make it easier
for the prefect to begin getting to know the
students (I personally know what a barrier it is
not to have a class list at your first session!).
17Options for Class Lists
- Best-Case Scenario Professors would supply
students with an electronic copy of an Excel
spreadsheet of the class at the beginning of the
term. Ideally, this spreadsheet would have the
names of all students in the class and on the
waitlist going down the left side. If the
information is at the professors disposal, it
would be really ideal for the spreadsheet to
include the gender, class year, and/or major of
every student as well. If all this is not
possible, it would be sufficient for prefects to
simply receive a list of students in the class,
as long it includes those on the waitlist and as
long as prefects receive and updated class list
after the drop-add period.
