Math Study Center Report
In 1987, the Math
Department acquired 40 computers and borrowed space in the Learning
Resource Center to start a program which would complement math
courses. The facility was eventually moved to rooms 356 and 376 and
renamed the Math Study Center. Students may work on computer
tutorials and/or receive help with math assignments from the
tutoring staff. The goal of the Math Study Center is to promote
success, retention, and persistence of math students at Grossmont
College. To determine if the goal was being met, research was
conducted during fall semester, 1995, spring of 1996 and again in
fall of 2000.
Math Study Center
(MSC) students were defined as those who made use of the MSC at
least once during the semester, thereby registering in the MSC's
database (N=917). These students were enrolled in at least one math
course during the fall 1995 semester. Non-Math Study Center (Non-MSC)
students were defined as those students enrolled in at least one
math course during fall 1995, who were NOT registered in the MSC's
database (N=3574). Success, as used in this study, means a student
received a grade of A, B, C, or Credit in his math course.
Procedure
MSC and Non-MSC students were examined on demographic and
performance variables. The demographic comparisons included gender,
ethnicity, and age. Performance comparisons were made in terms of
semester units completed, semester grade point average (GPA), grade
distribution in math course work, overall success rates and
withdrawal rates in math courses. In addition, these factors were
compared for specific math courses.
Data
were gathered during the fall semester, 1995. In terms of ethnicity,
there was a slightly higher percentage of Asians in the MSC group
than in the Non-MSC group. All other ethnic groups were represented
in slightly greater percentages in the Non-MSC group. There were
approximately the same percentage of males and females in the MSC
group as in the Non-MSC group. The students in the MSC group, on
average, were significantly older than those in the Non-MSC group
(F=56.28, p<.01). Younger students were more highly represented in
the Non-MSC group.

Students who used
the MSC, on average, completed more semester units than the Non-MSC
students. The MSC students also scored a significantly higher
semester GPA than their Non-MSC counterparts. In math course work,
MSC students had over a 20% higher sucess rate (A, B, C, or Credit)
than the Non-MSC group. Students who used the MSC also had about a
20% lower withdrawal rate than those who did not use the MSC.

The
study shows that as students get older, in general, success rates
increase slightly. A series of Chi Square analyses demonstrated a
significant average difference (p<.01) of about 20% for all age
groups with the exception of the over 50 group, which did not have
enough students to analyze statistically. However, it is important
to note that the differences between MSC and Non-MSC groups remained
somewhat constant across the age groups. Therefore, effects of the
MSC can be seen regardless of the students' ages.

Students who used
the MSC, on average, had 20% higher success rates in math than Non-MSC
students. Students who used the MSC during the fall 1995 semester
also completed more units and received a higher GPA overall than
students who did not use the MSC.
However, a few
cautionary notes need to be mentioned. As with any retrospective
study of this type, it is difficult to separate out differences
attributable to program effects versus differences attributable to
student endogenous characteristics, such as motivation. Students who
take advantage of the MSC may be inherently different from those who
have the opportunity, but do not use the MSC. Even with the
possibility of some self selection bias, the analyses show positive
differences in performance measures between students who use the MSC
and those who do not, across different courses and across different
age ranges.
