Abstract We are currently developing a new strategy for
mathematics assessment and remediation at the University
of Nevada Reno (UNR) and the South Dakota School of
Mines and Technology (SDSMT). As part of this strategy,
electrical engineering students take an on-line test of their
ability to use mathematics to solve context-based problems.
In this paper, we report on the result of the computer test for
students in an electrical engineering orientation class at
UNR. The results indicate a reluctance on the part of the
students to accept their mathematics deficiencies, which
hinders any attempt at remediation to reduce attrition.
INTRODUCTION
There is currently an unsatisfied need in industry for more
qualified engineers coupled with a disturbing decline in
college students pursuing technical degrees [1]. In addition,
the attrition rate among engineering majors is unacceptably
high [2]. There is strong evidence that suggests the high
attrition rate and the decline in enrollment are due in part to
weak skills in mathematics [3].
In response to the retention problem, the Electrical
Engineering Department and the Mathematics Department at
UNR teamed to develop a retention strategy targeting
freshmen electrical engineering students [4]. SDSMT is a
partner institution in this project. A proposed retention
strategy was developed and a formative study done to
identify high-risk students defined as those exhibiting weak
mathematics skills, and to provide remediation through peer
tutoring. This preliminary study sought to answer the
question: will an intervention plan using online computer
testing, advising and peer tutoring provide a viable retention
strategy for freshman electrical engineering students?
This paper describes the trial results of student
testing at UNR. Section II describes the student participants
in the test. Section III is a description of the on-line test.
Section IV is a report of the testing results. Section V gives
conclusions and future work.
PARTICIPANTS AND SETTING
Participants consisted of 48 freshman students enrolled in an
introductory electrical engineering orientation class, EE101
Introduction to Electrical Engineering, at UNR (a Carnegie I
university). The data was collected over a 16-week semester
using several methods including (a) formal personal
interviews (see Appendix A) with 6 students in EE101; (b) an
examination of university and college of engineering student
demographic records such as attrition rates, ethnicity,
gender, grade-point average, etc.; (c) completion of two
different surveys, an Engineering Attitude Survey (see Table
1) and a Math Anxiety Test (see Table 2), each administered
at the beginning of the semester and at the end of the
semester; and, (d) an online math test
(http://devnull.math.unr.edu/webtest ), developed by the
project directors and administered at the beginning of the
semester. All students were asked to take the online math
test again at the end of the semester but there were no
volunteers.
An examination of university data books located at:
http://www.vpaf.unr.edu/pba/ia/databook/index.html .
yielded several data groupings such as enrollment by year
(freshman, sophomore, junior, senior, graduate), age, gender,
ethnicity, college, and degree. From this data, freshman
attrition rates for the last ten years (1990-1999) were obtained
for the university overall (26.7%). However, the attrition rate
for students in the electrical engineering program is 58% over
a two-year period [2]. The high attrition rate for electrical
engineering majors appears to be primarily for students
enrolled in science and mathematics classes. Circumstantial
evidence indicates that one of the major reasons of attrition
is failure to acquire the mathematical skills necessary to
continue in the program.
An Engineering Attitude Survey [5] was
administered during the third week (pre) and again at the end
of the fall 2000 semester (post) to all students in the
introductory electrical engineering class (EE101). The
instrument was a 25-item, six-point Likert scale used to
measure attitudes and experiences associated with
engineering.
In addition, the EE101 class completed a Math
Anxiety Test [6], during the fourth week and again during the
final week of the fall 2000 semester. The instrument was a 21-
item, six-point Likert scale used to measure attitudes and
experiences associated with mathematics. The higher the
score, the more positive the attitude toward learning
mathematics. Since the instrument used in this study was
