Freshman-Level Mathematics in Engineering: A Review
of the Literature in Engineering Education
Abstract
Mathematics is part of the life-blood of engineering. While it is one of the essential tools
for doing engineering, it is believed to be one of the confounding variables tripping students in
their learning of the subject. In synthesizing the history of projects and research concerning
freshman-level mathematics as studied by engineering educators, this paper provides a report of
the patterns and themes engineering faculty have identified with algebra, trigonometry, and
calculus and provides a call for topics in future research. Because of a lack of published, peer-
reviewed journals connected to the topic, the exploration of themes in this preliminary report
focused on ASEE conference proceedings papers.
The papers reviewed will be analyzed to answer the following questions: What aspects of
freshman-level mathematics did the authors identify as problematic in their courses? What
interventions or changes served as the impetus for publishing? What literature is being used as
the context and foundation for engineers for their projects? What direction should future research
take?
Introduction
During the 1990s, congress, industry, and forums began to pressure universities to
increase the number of engineering graduates and their knowledge and abilities for the sake of
the US economy. Part of the pressure came from reports calling for reform not only of
engineering education but also of undergraduate education at the nation’s research universities.1
More recently in 2002, a report by Building Engineering & Science Talent (BEST) opened with
the statement,
There is a quiet crisis building in the United States — a crisis that could jeopardize the
nation’s pre-eminence and well-being. The crisis has been mounting gradually, but
inexorably, over several decades. If permitted to continue unmitigated, it could reverse
the global leadership Americans currently enjoy. The crisis stems from the gap between
the nation’s growing need for scientists, engineers, and other technically skilled workers,
and its production of them.2
As a result, engineering faculty have been looking at how and at what they teach in order to
address this quiet crisis.
For the past two years, the Journal of Engineering Education (JEE) has trumpeted the
need to establish engineering education as a rigorous-based field of study. Rising pressure in its
editorials mention the need for engineering faculty to equip and develop the best pedagogical
practices, make adjustments to enhance diversity, collect and employ foundational theory
knowledge, switch from behaviorist to constructivist paradigms in teaching, and provide
educational research that is as rigorous as their engineering-content research.3,4,5,6
Thus, there is
a call for engineering faculty to develop their understanding of teaching and learning theory and
its applicable practices along with developing as engineering-educational researchers.
Page 13.627.2
In trying to recruit and strengthen engineering programs, many engineering faculty
choose to research and receive grants that investigate mathematics, science, and engineering in
the K-12 system and university-level mathematics courses. Mathematics is seen as the
foundation and life-blood of engineering. While engineering faculty view it as one of the
essential tools for doing engineering, it is also one of the confounding variables tripping students
in their learning of engineering. Engineering faculty are often able to perceive the problems with
algebra, trigonometry and calculus in their students’ coursework.
Students learn mathematics in courses during high school and college. Mathematics
courses at the high school level concern themselves with the subjects of algebra, geometry,
trigonometry, and calculus. Freshman-level mathematics courses at the university level concern
themselves with three of the same topics: algebra, trigonometry, and calculus; however,
occasionally, universities will choose to designate calculus as a sophomore level mathematics
course. Despite how courses are named or organized at the high school or college level, the
mathematics content is very similar, and for the purposes of brevity for this paper, the subjects
of algebra, trigonometry, and calculus will be grouped together and referred to as freshman-level
mathematics.
Rationale and Purpose of this Study
In working with students while teaching their courses, many engineering instructors are
able to know, recognize, and report the mathematical knowledge their course requires as well as
their students’ struggles and weaknesses in remembering or applying the mathematical content or
processes. Because coursework is often divided among disciplines, students’ mathematical
instruction is out-sourced to mathematics courses as a pre-requisite to engineering instruction.
Thus, if NSF and other funding agencies support the work of engineering faculty in investigating
mathematics to develop educational projects and research for possible solutions, student learning
can be better streamlined. This is because engineering faculty have the advantage of recognizing
the mathematical content and processes necessary for their course as well as students’ current
weaknesses in understanding this mathematics. It can be argued that they who receive funding
or acceptance for published works must have identified problems with students’ understanding
and developed strong arguments for possible solutions to mathematical weaknesses.
In synthesizing the literature concerning freshman-level mathematics as studied by
engineering educators, this paper intends to contribute a report of the patterns and themes
engineering faculty have identified with freshman-level mathematics and what they have
attempted to change or research. In providing these summarized themes from the literature, this
paper intends to provide guidance for future research and projects by answering the following
research questions:
� What do engineering faculty perceive and/or identify in their courses as problematic with
students’ understanding of freshman-level mathematics?
� What do the authors suggest as the direction for future research?
The audience for recognizing and understanding the problems engineering faculty have
identified in their courses concerning freshman-level mathematics are high school math teachers,
Page 13.627.3
university math instructors, mathematics-education researchers, engineering-education
researchers, and mathematics curriculum designers.
Methodology
Due to a lack of literature and leads found in PRISM, Journal of Engineering Education
(JEE), and on-line journal web-databases concerned with freshman-level mathematics, ASEE
conference proceedings papers were analyzed. Conference proceedings papers were chosen
because they are known sources for including current projects in improving science, technology,
engineering and mathematics (STEM) education in K-12 and college-level mathematics courses.
In using the conference proceedings papers, the author hoped first to find initial themes
concerning algebra, trigonometry, and calculus as a goal of this paper and secondly to use the
cited references as a spring board for finding and further broadening the literature review into
published journal articles.
For this preliminary report, conference papers from the 2006 American Society for
Engineering Education (ASEE) conference proceedings archives were analyzed.9-31
While the
search engine was used to locate papers with mathematics in the title, it was not used
exclusively. Since some related papers may be tucked into non-mathematical, content-specific
sessions without mathematical words in the title, all titles for papers published for the 2006
conference were examined for possible connections to the purposes of this paper. To be included
in this analysis, the conference paper must have some connection to improving the learning or
teaching of algebra, trigonometry, or calculus. Topics connecting to other mathematics, such as
differential equations, were not included. The mathematics did not have to be the focus of the
paper, but the paper had to serve directly to the purposes of improving the learning or teaching of
mathematics in algebra, trigonometry, or calculus.
Twenty-three papers fit the criteria for inclusion in the analysis and are referenced in the
appendix. Each paper was analyzed for the how it answered the following questions:
1. What aspects of freshman-level mathematics did the authors identify as problematic in
their courses?
2. What did the paper position as the underlying problem?
3. What interventions or changes served as the impetus for publishing?
4. What was studied?
5. What did the paper suggest as direction for future research?
6. What sources of literature did the paper reference?
7. To what degree was the paper and study situated in literature?
The greatest goal while analyzing the papers was to list any problematic areas authors mentioned
about freshman-level mathematics. The goal of the remaining six questions was to explore and
report the assumptions, actions, and future vision of the authors for the use of researchers
building from these initial works. Thus, the second and third questions elaborated on what the
authors perceived as the root of the problem and how they attempted possible interventions,
changes, or studies to address the problem. The fourth question, concerning what was studied,
helped support the second question and was necessary because, for example, while two papers
may evaluate the success of teacher workshops, one may study future student learning and the
other may study teachers’ perceptions of the program on survey responses. The fifth and sixth
questions developed themes for future work, and the last two questions served as gauges for
Page 13.627.4
determining the reliability and strength supporting the claims made by the papers. The last two
questions also served as points of reference in broadening this literature review toward published
articles later.
In classifying references, a 5-point rubric was created to assess the degree to which the
argument and theoretical framework is situated in existing literature and the degree to which
substantial claims are supported by needed references. In this manner, the caliber of the
reliability for the claims and conclusions in the paper can be reported. The logic of each paper
was noted, and the claims and supporting evidence within the logic were analyzed for reliability.
Both the quality and quantity of sources were considered. In research, originality is favored;
however, the audience expects formal research papers, like the ones found as conference papers,
to situate their research projects in existing literature and argue how their project builds from and
extends beyond prior efforts. In this way, research informs itself and systematically develops
cumulative knowledge in order to advance the field. Thus, the papers were first evaluated on
whether the current work was situated within existing literature and then further evaluated on
whether claims were supported by appropriate of evidence within existing literature. The rubric
is as follows:
A. Positions current work within prior work and existing
literature? (Knows what’s been done before?)
B. Backs claims with evidence from prior research or existing
literature?
Yes
No
1: Surface
references
2: Supports

3: Lacks some

4: Backed by

Figure 1: Assessment Rubric for Gauging Use of Literature
Each paper was first scored whether it couched its work within earlier literature. If it did,
then it was assessed for its ability to back its supporting claims with appropriate literature. If the
paper did not couch its study in the literature, then its ability to support its arguments with
references in the literature were also assessed. The support any particular claim requires can be
moderately subjective and based on the intended audience. The nature of some claims requires
only one valuable reference as evidence; other times, the nature of a claim requires several
references as sufficient support. The rubric was used with the assumption that the intended
audience for these conference papers was people associated with academia, who would require
substantial evidence for all claims and that evidence come from reliable sources.

Problems Reported with Freshman-Level Mathematics
Because the papers were chosen as having a connection to the teaching and learning of
mathematics, the problems reported with freshman-level mathematics did not have to be central
to the purpose or logic of the overall paper. Thus, the problems found concerning the
mathematics can be different than the overall problem the paper seeks to explore.
Four themes surfaced within reporting the problems engineering faculty describe with
freshman-level mathematics. Two of the 23 papers (9%) concerned themselves with Calculus as
problematic for retention within STEM, and nine papers (39%) addressed students’ inability to
apply and connect mathematical content and/or processes within engineering courses. One paper
(4%) focused on the need for the conceptual understanding of a topic. Eleven papers (48%) left
the problem unstated or unclear.
Both papers concerned with retention in Calculus served to create theory. The first
looked at whether help-seeking behavior could be a possible predictor for success in the course,
and the second looked at whether a web-based tutorial program could serve as a method of
predicting proper student placement into Calculus I.
Of the nine papers attributing the problem to an inability to apply the mathematics,
several reasons were given. As examples, the papers asserted their goals to address “engineering
students [as] better problem solvers” across STEM courses,20
students’ “lack of mathematical
skills,”27
students’ ability of “connecting mathematics with context-rich content and processes in
science and engineering,”23
and students’ lack of “ability to put mathematics knowledge and
skills to functional use in a multitude of contexts.”9 The difficulty with these claims is that all
but two papers lack details and/or evidence to support such claims. The claims lack the specifics
of the contexts in which engineering faculty refer, which is problematic because it leaves the
reader unsure of whether it is mathematical content, mathematical processes, or a combination of
both.
Interestingly, seven of the nine papers argue that mathematical knowledge and processes
are best gained through applications. They argue the need to teach or re-teach mathematics
within applications of STEM topics in order to increase student success. It is unsubstantiated by
theory and supporting research, but it is a valuable theme for the exploration of this paper
because the research question asks what engineering faculty perceive as the problems with
freshman-level mathematics.
Unable to be classified with the others, one paper argued the need for students’
conceptual understanding of infinity based on personal experiences with engineering students.
The paper proposed a framework along with practical activities to promote students’ conceptual
development.
Overall, six papers mentioned specific content knowledge, which is helpful because it
helps readers know what mathematics is used in engineering. Topics included “mathematical
function and covariation,”23
“percent, measurement, area, and perimeter,”13
“matrix
Page 13.627.6
manipulation, conic sections, series, and linear regression,”10
“topics covered in College Algebra
and Trigonometry,”12
“concept of infinity,”22
and “tessellations, curve surfaces, and subdividing
space by solids.”31
All but one of these topics were chosen by either experts or instructors based
on their knowledge that engineers use this content in their field. Only one topic, mathematical
function and covariation, was chosen in direct connection to a study recognizing student
difficulties. Thus, for the purposes of this exploration, content topics are mentioned but only one
paper supported as problematic within engineering coursework.
Proposed Direction for Future Work
The second research question focused on reporting themes across the papers in regard to
what engineering faculty propose as possibilities in future work. Of the 23 papers, fifteen papers
mentioned direction for future work, but all but two detailed future work to be done by the
authors. Of the two that offered future work to its readers and other researchers, both were calls
for larger sample sizes in order to further test the work of the current author.
Thus, there were no themes—neither mathematical nor otherwise—across the papers where
engineering faculty proposed direction to their audience to extend and generate new research
other than the possibility of providing larger sample sizes to current work. This can partly be
explained by the impetus for publishing, which is described later in the paper.
Description of the Papers
In most cases, each paper opened by describing a significant problem of interest to the
audience which would be addressed by the study. Sometimes the problem lay unstated but easily
surmised by the goal of the paper, other times it was stated openly. In suggesting the problems,
several papers ascribed multiple points; however, all but one paper centered its argument on just
one particular problem. Figure 3 shows the patterns that emerged.
Page 13.627.7
The problem mentioned most often (41.7%) was the need for increased student interest and/or
exposure to STEM related topics. The theme of interest and exposure could not be further
subdivided because the papers seemed to assume increased interest would result in further
exposure and increased exposure would further interest. Eight papers (33%) attributed the
problem as students’ weakness in either mathematical content or process skills. Five of the
eight papers did not elaborate as to what weaknesses they observed. Only three papers noted
specific difficulties for students. These included an understanding of mathematical function and
covariation, a conceptual understanding of infinity, and a lack of problem solving ability. Of
the four papers that cited retention as the problem (16.6%), two concerned themselves with
retention in and past calculus, one addressed retention past mathematics courses in general until
the junior year, and one looked at high school retention and also in STEM fields during college.
Lastly, one paper concerned itself with student engagement in group activities based on gender
differences, and the last addressed questioning as a more beneficial sequencing of student
content as a result of how students learn.
It could be easily argued that 5 of the 8 papers attributing the problem to students’
weaknesses in mathematics along with 2 of the 4 papers pertaining to retention could also be
grouped under exposure. The logic of these seven papers follows that if students had further
exposure to mathematics, then their mathematical weaknesses could be eliminated and concern
toward their retention in STEM courses would be reduced. Thus, 17 of the 24 (70.8%) of the
papers could be classified as pertaining to interest/exposure.
Interestingly, only one paper stated the need for students to recognize connections
between STEM topics within the mathematics course; however, this theme seemed to be an
assumption which surfaced in many of the papers. With only one paper attributing the lack of
connections as the primary source for the problem while many other papers seemed to point in
that direction also, it may be possible that engineering faculty believe that exposure to STEM
topics is central to increasing retention and content knowledge. By using this collection of
papers, a reader could strongly argue that engineering faculty believe students who lack
exposure to STEM will lack interest and have weak content knowledge, and this in turn causes
Page 13.627.8
students not to enter STEM related fields or causes them to drop-out of high school because of
high-stakes testing. In believing a lack of exposure to STEM creates the problems with
retention and knowledge of the subject, the authors of the papers indirectly make the statement
that exposure to STEM topics will serve to recruit and build greater learning.
Having stated their problems, the papers then argued the need for their choice of intended
study, intervention, or change in order to address or better understand the significant problem.
In attempting to address the above mentioned problems, the interventions or changes which
served as the impetus for publishing fell into six basic categories with the sixth category
requiring subdivision (see figure 4).
The most common impetus for publishing was professional development for teachers
where the goal was to increase teacher content knowledge and provide the teachers experiments
for their classes. Eight papers addressed professional development for teachers either through
week-long workshops or professional development classes.13,14,19,21,23,25,26,30
Two of these studies
also included interactions with students during the workshop or professional development
days.21,26
Six of the eight papers used teacher development programs as the intervention of
choice in increasing student interest and exposure to STEM topics, and the remaining two papers
were classified as either attributing retention or weaknesses in mathematical ability as the
problem, but both of them could also argue to be classified as attributing the need for increasing
exposure and interest as the problem.
The second largest category was the seven papers which did not center on reporting an
intervention or change. These could be sub-divided into two chategories: research-driven
questions and assertions. Five papers were exploratory and driven by research
questions.10,15,20,21,29
For example, one paper investigated the correlation between help-seeking
behavior and student performance in a large calculus class. Other topics explored were the
ability to predict student preparedness for calculus, problem-solving vocabulary similarities and
Page 13.627.9
differences across all STEM courses, gender performance differences in different group
activities, and the nature of a high school curriculum to prepare for engineering course work. Of
the two papers in the second subcategory characterized as being assertions by the authors, one
was a statement by the author for how infinity should be taught, and the other posed the
usefulness of a tree diagram in helping instructors decide the sequencing student learning should
take. 18,22
All seven of these papers did not attribute interest and exposure as the problem, but
were evenly spread among the remaining themes from the attributed problem.
Of the remaining eight, one paper mapped student learning to teachers hits on their
created web-library,11
two created entirely new courses to address mathematical needs,12,31
three
added activities to existing courses,9,27,28
and two papers addressed activities for students,16,17
specifically one was a week-long summer camp and the other was a science club. Of the two
that created new courses, one paper described a one-hour course studying applications of algebra
and trigonometry and the other described a three-hour course focused on the mathematical skills
needed for architecture. Of the three that added an activity to their existing courses, one included
more quizzes and two included projects in calculus courses. Half of these remaining papers
sought to increase interest and exposure while three sought to decrease student weaknesses in
mathematical ability and one sought to decrease dropouts within STEM related fields.
Knowing the intervention or change for each paper was not sufficient to categorize the
papers. For example, some of the papers which had teacher workshops as the intervention for
the impetus of publishing studied teacher attitudes toward the workshop while others studied
student learning during the school year. Thus, the question of what was studied is necessary for
the analysis.
Of the 23 papers studied, 12 studied student perception and/or learning, 9 studied teacher
perception and/or learning, one studied university STEM faculty, one studied curriculum, and
four did not study anything but instead were declarations of statements or descriptions. The
overlap results from some papers studying multiple sources in order to strengthen its findings.
Of these 23 papers, 15 focused on evaluating or describing an activity or program, five had the
purpose of being a research study, two were papers with the purpose of declaring a particular
statement of interest, and one sought to evaluate an on-line resource (see figure 5).
Page 13.627.10
Appropriate to the discussion is the need to compare evaluative research and basic
research studies. Michael Quinn Patton, a popular scholar on research, makes the distinction,
Evaluative research, quite broadly can include any effort to judge or enhance human
effectiveness through systematic data-based inquiry….The question of whether the
people involved are accomplishing what they want to accomplish arises. When one
examines and judges accomplishments and effectiveness, one is engaged in evaluation.
…Research, especially fundamental or basic research, differs from evaluation in that its
primary purpose is to generate or test theory and contribute to knowledge for the sake of
knowledge.7
Though research hopefully guides choices in future activities, its purpose of developing
knowledge is solely different from evaluation. The nature of the focus and purpose of the papers
divides the papers accordingly.
Of the 15 papers which had the purpose of describing or evaluating an activity or
program, three evaluated the success of adding an activity to a course. All three of which
included scores for student perceptions of the activities and their learning as a result. Two of the
fifteen had the purpose of evaluating newly created courses. Both evaluated the course success
with scores from class grades and surveys concerning student perceptions of the course.
The last ten described teacher workshops, professional development days, a student
science club, and student camps with eight of the papers including evaluations of the activities
using either surveys for perceptions, observations of pedagogical behavior, or tests to evaluate
learning. Three papers assessed the program with teacher perceptions, two assessed teacher
learning and then observed them in their classes, two assessed with both teacher and student
surveys for perceptions, and one assessed by asking teacher perceptions and evaluating later
student learning. Of the eight papers which included evaluations, three papers made broad
statements concerning the results of their surveys, but the rest included the anlaysis formally.
The five research studies were concerned with student performance on a gender basis on
four activities, whether a computer program could be a predictor of success in calculus, whether
student help-seeking behavior correlated with success in calculus, STEM faculty differenes in
uses of problem solving techniques and vocabulary through interviews, and whether students
were prepared in their mathematical content knowledge for engineering courses by interview
teachers, observing their classes, and testing college freshman content knowledge.
Description of the Papers’ Literature
Literature used to situate the context of each paper and to support claims within the
papers were from various sources. Just under half of the sources, 104 of 220, looked at
education in general coming from the disciplines of Cognitive Science, Psychology, or
Education, and 95 of of the remaining 116 were split among Engineering Education,
Mathematics Education, and STEM Education. Figure 6 reveals the types of literature cited.

Types of Literature Referenced
Figure 6: Breakdown of Literature Referenced into Categories
While the central theme for all twenty-three 2006 ASEE conference papers relates to
somehow improving freshman-level mathematics, a surprising low percentage (16%) of papers
referenced math-education research and literature, which comes from the discipline that studies
the learning and teaching of mathematics. Also a surprising number of references were reports
or conference papers (18%). Both were often referenced when describing the problem or
supporting arguments which served as the impetus for undertaking the project or paper.
Conference presentations accounted for another 14% of the sources. The ten mathematical
references were mathematics textbooks. Only 41% of the references were published, peer-
reviewed journal articles.
In using the 5-point rubric to assess the degree to which the argument and theoretical
framework was situated in existing literature and the degree to which substantial claims are
supported by needed references, ten of the papers couched their study in literature (scoring a 3 or
4 on the rubric), and 4 of the 10 successfully backed its supporting claims with the needed
references (scoring a 4). Thus, only four papers (17%) offer literature and references of the
caliber needed for being highly reliable and valid. Of the 13 papers that did not situate their
research projects in existing literature and argue how their project builds from and extends
beyond prior efforts, three adequately supported arguments with needed evidence (scoring a 2),
four referenced sources on the surface but not integral to its logic and argument (scoring a 1),
and six had no references or only referenced other sources written by the author of the work
(scoring a 0).

Summary & Discussion
Increasing the number of students entering STEM fields and the quality of STEM
graduates’ knowledge and skills when entering the workforce are practical problems which can
be solved by doing something to eliminate the causes leading to undesired outcomes. The
authors of these articles exampled for this study, with a focus on math, have sought to increase
desired outcomes by professional-development for teachers (39%), adding new components to
current courses (13%), camps and science clubs for students (8.7%), and developing entirely new
courses (8.7%). The most common practical problem (41.7%) was identified as interest and
exposure to STEM topics with another 29.1% of the papers containing the similar argument but
argueing that lack of exposure and interst causes the practical problems of weaknesses in
mathematics and low retention. Thus, 70.8% (17 of 24 topics) of the papers are argued to
increase interest and exposure to STEM topics.
Because engineering faculty have invested their time doing something to eliminate the
undesired outcomes, the purpose of 70% of the papers was to evaluate their efforts. Evaluation
papers are not meant to be generalizable because
good evaluation is quite specific to the context in which the evaluation object rests.
Stakeholders are making judgments about a particular evaluation object and have less
desire to generalize to other settings than a researcher would. …In contrast, because the
purpose of research is to add to general knowledge, the methods are designed to
maximize generalizability to many different settings. If one’s findings are to add to
knowledge in a field, ideally, the results should transcend the particulars of time and
setting.8
One of the leading reasons why it may be appropriate for the papers not to have proposed
direction for future research is the papers were not research oriented but rather evaluation
oriented. Describing the project and noting direction for future work by the authors is
appropriate for papers with purpose toward evaluation. Unfortunately, only two of the five
research studies offered direction for future work. This may be a result of authors feeling that to
offer advice for their readers for future work would undermine the strength and completion of
their own work—or any other multitude of reasons. However, engineering faculty have much to
offer to the field if they were to offer direction for future research stemming from their
participation in either evaluation or research studies, which is often done by educational
researchers in their articles. Engineering faculty also have much to offer in developing the field
of science if they were to complete research studies with the intent of gathering knowledge on
the problems underlieing STEM topics and processes in their courses. Research studies are
intended to be generalizeable, and they offer progress to a systematic study of the field, which in
turn also better informs practice.
Typically, conference papers are not judged as intently as peer-reviewed journal articles
are; however, surprisingly only 4 of the 23 papers (17.4%) situated their work in existing
literature along with the needed references as evidence for supporting claims. Without situating
current work in existing literature, the authors fail to help progress the systematic study of the
field. It is unrealistic, nor recommended, to expect engineering faculty to become experts in the
study of the learning and teaching of mathematics, but if grant money supports their efforts in
mathematcial projects such as professional development for teachers, experts in engineering
Page 13.627.13
should use the practical and theoretical research offered by experts and involve experts in
mathematics-education in creating the framework and direction for their work. Informed
decisions would advance the progress in both fields.
The quality and types of references also are important in progressing the field of study.
References from general education, cognitive science, and psychology comprised 47% of the
sources referenced; whereas, a surprising low percentage (16%) of papers referencing math-
education research and literature. The context of details provided by particular fields of
education, such as mathematics education, as compared to general education cannot be
underestimated. In terms of quality, a surprising number of references were reports or
conference papers (18%) and conference presentations (14%), which comprises a third of the
references. Only 41% of the references were published, peer-reviewed journal articles with
another 14% referencing books.
Another complication with the papers was the lack of detail supporting how mathematics
is problematic within engineering courses. Six mathematics content topics were mentioned,
which is powerful for informing the audience of what mathematics is needed in the field, but
only one content topic, mathematical function and covariation, was chosen having been
supported by evidence from a prior study as being problematic for students. Engineering faculty
have much to offer audiences from mathematics education concerning mathematics use in their
courses. Possible questions include: What mathematics is used in your courses? How is it
used? How is the mathematics in engineering courses used differently than in mathematics
courses? What about mathematics is problematic for students when they are called to apply their
mathematical knowledge and processes? It should be noted, one complication for answering
these questions is they would require qualitative methods because they are inductive and seek to
explore and describe the situation. It is highly recommened for systematic progress within the
field that engineering faculty work to understand the nature of the problem and collaborate with
educators who are trained in qualitative research methods—especially those who are familiar and
trained within research concerning the teaching and learning of mathematics.
An example of a possible research paper which would be of great value to STEM
education was referenced in “Project Pathways: Connecting Engineering Design to High School
Science and Mathematics in a Mathematics Science Partnership Program” by faculty at Arizona
State.23
Mentioned briefly within the paper but offering richness if fleshed out in a full research
study, the authors noted “between disciplines, there are gaps in knowledge, issues in
terminology, and differences in ways of thinking about function and covariation and its
applications.”23
If these “language and notation barriers between math and science teachers”23
were studied and reported, issues with student learning could be identified. Thus, this evaluation
report concerning teacher workshops discovered an issue that could be a very valuable research
topic.
Noted earlier, 70.8% (17 of 24 topics) of the papers argued to increase interest and
exposure to STEM topics. Of these 17 papers, 41% argued that the problem with freshman-
level mathematics is its need to be taught through application. In other words, 77.8% of the
papers which argued the percieved student problem with freshman level mathematics is their
inability to apply mathemtical content and processes across STEM disciplines also aruged
Page 13.627.14
interest and exposure as the overall significant problem. The difficulty with these descriptive
statistics is they do not offer an answer as to why engineering faculty believe applications
increase student learning and understanding of mathematical topics. For future research, this
attitude among engineering faculty should be explored and compared to mathematics-education
research focusing on learning in context.
Thus, possible questions to be answered: Do engineering faculty believe students
practice of applying math in STEM topics increases students’ learning of mathematical content
and/or process skills? Is there a correlation between people choosing engineering as their field
of study and those who enjoy applications of mathematics? In developing their own
mathematical understanding with success, has applications of mathematics been a leading cause
for people choosing engineering as their field of study? What about applications with STEM
topics increases student learning of mathematics? In studying students learning of mathematics,
is there literature to support that increased interest and exposure to STEM topics would increase
student learning and recruitment into STEM related fields? Is the correlation between increased
exposure and gains in retention, recruitment, and learning significant? What does literature
report as the sources of interest for current experts in engineering choosing the field?
Conclusions
It is possible that many of these questions posed here are already within existing
literature. This paper serves to be exploratory and an initial excursion to understand the
problems concerned with freshman-level mathematics and engineering. Overall, the two
research questions were not able to be answered. Engineering faculty have not reported in these
papers with enough detail the problems with students’ understanding of freshman-level
mathematics as identified in their engineering courses, and there were no suggestions for future
research springing from their current work except to repeat their work with larger sample sizes.
This literature lacks specifics of what can be identified as the problems with freshman-level
mathematics. The following three questions remain:
• What mathematics do engineering faculty use in their courses?
• With what aspects of mathematics do engineering faculty see their students
struggle?
• What do engineering faculty observe students doing/saying as they struggle with
the mathematics in their courses?
Despite the lack of success in answering the research questions, this analysis reports
70.8% of the papers display engineering faculty’s perceptions that interest and exposure are the
leading problem to be tackled, and 47% of these papers sought to address the issue of interest
and exposure by conducting professional development programs for teachers, which was 35% of
all the papers in the analysis. In analyzing the nature of the research, 82.6% of the papers
demonstrated neglect in supporting the logic and claims within existing literature, and 70% of
the papers were evaluative in purpose, which does not contribute to the systematic study of the
problems within the field and has little generalizability for other works.

Engineering faculty seem to participate and get funding for programs and interventions
without identifying the problem with the mathematics in their courses. There seems to be a
belief among the papers when taken together that a lack of exposure to STEM is the problem.
Many of the papers where teachers and students participated in a camp or workshop provide data
reporting positive beliefs in the learning gains from participating in the workshops or camps.
Teachers also report desiring to implement projects from workshops into their courses, but they
report lacking the time. If teachers claim learning from the workshops and desire to implement
the projects into their courses, engineering faculty must be creating useful workshops for the
teachers. Unfortunately, the details of their workshops are not part of the literature, which keeps
a larger audience from benefiting from the content of their workshops. Practical activities and
worksheets are sought by teachers participating in the professional development, but the nature
of the content and purposes of the activities are valuable knowledge within research literature.
There is a need for engineering faculty to note the differences between what engineering faculty
perceive as differences between their current courses and what K-12 schools already do in their
courses.
This paper sought to summarize engineering faculty’s views on their students’ uses of
algebra, trigonometry, and calculus. In the initial search for articles, few articles were found of
use to the topic of interest; therefore, the project was reshaped to analyze only the 2006 ASEE
conference papers for possible themes and leads for further exploration. To broaden the
literature review into published journal articles, the following journals associated with science
and engineering should be explored: International Journal of Engineering Education,
International Journal of Mathematics Education in Science and Technology, Journal of College
Science Teaching, Journal of Research in Science Teaching, Journal of STEM Education, and
Science. Other journals not directly related to the STEM field but containing articles of interest
to this topic include American Journal of Education, Cognition & Instruction, Cognition &
Science, Educational Researcher, Journal of Education, and New Directions for Teaching and
Learning. Lastly, journals directly linked with the study of mathematics should be explored for
authors or co-authors who are faculty within engineering.
In conclusion, five audiences would benefit from both practical and research literature:
high school math teachers, university math instructors, mathematics-education researchers,
engineering-education researchers, and mathematics curriculum designers. There are many
possibilities for future research taken from themes found in this paper. Many possible questions
are mentioned in the discussion section. Overall, there is a need to explore through research
what mathematics is used in engineering courses and how it is used, which would be a valuable
resource for the five audiences in systematically building, studying, and understanding the field.
Some of the research questions would be best explored by a math-educator who can look through
their lens of expertise of common students’ K-12 experience based on current policies on
content, the theories of semiotics, and theories of cognitive development in a social environment.
Other questions are best tackled by engineering faculty, especially those which describe the
nature of student misconceptions and lack of abilities in using mathematics in engineering
courses.
