The Value of Research in
Undergraduate Chemistry Education
During the first two breakout sessions, participants engaged in discussions
of the value of research in the undergraduate chemistry experience, and
the strengths and weaknesses of the traditional model of undergraduate
research in which an undergraduate, typically during their junior or
senior year, engages in research under the direction of a single faculty
mentor. A summary of the relevant points made during these discussions
and conveyed during the reporting sessions is contained below.
Undergraduate research has been a cornerstone of the undergraduate major
in chemistry for decades. Its value as an educational component in the
undergraduate experience was enhanced by the Undergraduate Research Participation
program established by the National Science Foundation in the early 1960’s.
Since that time, the chemistry community has willingly embraced the traditional
single faculty mentor-student apprentice model of undergraduate research
for advanced undergraduates, and anecdotal information suggests that
many students choose to pursue graduate work in chemistry or related
disciplines as a result of such undergraduate research experiences. From
the 1960’s to the mid 1990’s, the number of undergraduate chemistry degree
recipients steadily rose, suggesting the health of the undergraduate
structure. However, since the mid 1990’s, the number of degree recipients
in chemistry has begun to decline. Although some argue that if all biochemists,
chemical biologists, and environmental discipline degree recipients are
included in the count of baccalaureate chemistry degrees, the numbers
do not support a decline, the number of traditionally-trained chemistry
degree recipients (i.e. those largely educated in chemistry programs)
does appear to be decreasing due to increasing specialization of the
field and proliferation of more interdisciplinary areas. The consensus
is that the decline in majors is attributable to multiple factors. Less
chemistry is required in other majors such as engineering or nursing
today compared to a decade ago. Chemistry-related disciplines such as
biochemistry and environmental science are siphoning off a fraction of
the top students, since students tend to view the chemistry major as
“too hard” or less relevant than these other areas. Finally, the perceived
“staleness” of the chemistry curriculum undoubtedly contributes to this
loss as well.
Other educational and societal factors also contribute to this decline
in chemistry majors. These include education problems in science at the
K-12 level such as poorly trained teachers and teaching to standardized
tests, and as documented by Seymour and Hewitt in Talking About Leaving,16
the lack of student knowledge of career opportunities in chemistry, poor
teaching in undergraduate chemistry at the general chemistry level, and
the fact that students entering college no longer perceive the physical
sciences such as chemistry to be either desirable or achievable as career
aspirations.1 This latter factor is particularly problematic for attracting
women and minority students into careers in the sciences.
Of this list of contributing factors, changes in the undergraduate degree
program in chemistry would seem to be the most straightforward to address.
The general perception that undergraduate research experiences play a
pivotal role in students choosing to pursue careers in the sciences is
commonly held. Indeed, a small but growing body of research supports
this perception,3,6-9 although this hypothesis has not yet been proven
on a large scale. Nonetheless, if one assumes that undergraduate research
is a significant factor in student career choice, a logical extension
of this assumption is that increasing the availability and accessibility
of undergraduate research opportunities for students has the potential
to not only improve the educational experience for all students taking
chemistry courses, but also increase the number of undergraduate chemistry
majors.
Research creates knowledge, communicates discovery, and provides a significant
opportunity for the mentorship of students. Research additionally increases
the confidence of students, stimulates their curiosity, improves their
communication skills, and enhances their critical thinking and problem-solving
skills.9 Research can generate sustained and persistent enthusiasm that
contributes to the retention of a student either in a specific discipline
or even in their undergraduate studies. Research mentoring can lead to
the efficient integration of students into research communities in a
way that clearly establishes their career paths.3 The age of students
involved in research is not nearly so important a factor as their ability
to relate well to a mentor. Alumni of undergraduate research programs
indicate that the research experience itself was a central factor in
their perceptions of their undergraduate experience, regardless of whether
this experience lasted 6 weeks or 4 years.3,6-9 Not enough is known about
why research has such an impact on undergraduates, so further investigation
in this area might be encouraged as part of the development of URCs.
One difficulty in increasing undergraduate research experiences for
undergraduates according to the single faculty mentor-student apprentice
model is the limited number of undergraduates that this model can accommodate
within the existing faculty capacity. Although the number of students
who can be involved successfully in research under the direction of a
given faculty member depends on that faculty member’s capacity for mentorship,
the notion of significantly broadening participation in undergraduate
research to include freshmen and sophomores will require new paradigms
for providing such research experiences within the existing faculty capacity.
The possibility of soliciting mentors from sources other than the regular
faculty ranks (e.g., postdoctoral researchers, graduate students, advanced
undergraduates, national laboratory or industry scientists) was discussed,
as was the possibility of designing “science semesters abroad,” similar
to the traditional semester abroad to expand undergraduate research opportunities.
The content of research should be distinguished from the experience value
of research in relation to the level of student involved: a significant
research experience for a high school student would most likely not be
a significant experience for a postdoctoral student.
As has been shown by recent studies,3,5-9 mentorship is the critical
component of any undergraduate research experience and increasing the
system’s capacity for such mentorship requires, at the very least, support
at the institutional level in the form of recognition of research mentoring
activities and curricular reform. Given its value as an educational experience,
there is a developing movement nationwide to require undergraduate research
or other significant independent creative work as part of all curricula.
To achieve this end, research must become part of an institution’s fabric
as an inherent value that supports and strengthens the education of students.
Institutionalizing research will automatically involve more students,
but will also require institutional change both in terms of curriculum
reform and the faculty reward structure. Continued curriculum reform
to better integrate research activities is needed. Engaging students
as scientists early in their educational experience in active, discovery-based
labs can provide a logical developmental pathway for their later successful
involvement in research. An additional approach that might be helpful
in developing some of the appropriate skills needed for research early
in the undergraduate career of students is the model of the Research
Methods course frequently used in the social sciences.
In order to implement such curricular change, the limitation of faculty
time must be acknowledged and addressed. Faculty time for mentoring undergraduate
research and/or curricular reform is limited and expensive, but critical
for successful education in chemistry. Institutions must be encouraged
to find adequate resources in terms of faculty release time for the curriculum
development necessary to support an institutional culture of research.
In addition, since good undergraduate research mentoring requires considerable
faculty time, faculty must be provided with release time or teaching
credit for mentoring activities. Faculty participants of this workshop
almost uniformly cite faculty time as a critical limitation to further
broadening undergraduate participation in research.
Further limitations to the traditional model of undergraduate research
involving the single faculty mentor-student apprentice include those
directly related to the students. Student course and work schedules often
do not allow adequate time for engaging in time-intensive research activities.
This problem can be exacerbated by insufficient stipends for students
who must work to support themselves, a scenario of increasing frequency
especially in environments such as community colleges or urban campuses.
Moreover, students are often unaware of research opportunities, especially
in large, impersonal institutions such as many research universities,
urban institutions, or community colleges.
Many research opportunities have historically been given to those perceived
to be the “best” students, those students already committed to the discipline,
or those students already possessing a particular skill set. This selectivity
has often led to diminished opportunities for women and minority students,
and neglects potential “diamonds in the rough” among student populations
other than those who have historically pursued chemistry as a career.
Such selectivity for research experiences is unfortunate, however, since
among populations of students who are not necessarily predisposed to
science, successful research experiences can often lead to attracting
these students to pursue a science degree.
Student research experiences can also be variable in quality depending
on the mechanism used to establish faculty mentor-student relationships
and depending on faculty expectations of undergraduate researchers. In
some programs, random assignment of faculty mentors can lead to unsatisfying
research experiences for a portion of undergraduate participants. Unrealistic
faculty expectations for research productivity of undergraduates can
also lead to a negative student perception of the experience. Therefore,
it is of the utmost importance that mentor relationships be allowed to
develop spontaneously whenever possible and that adequate attention be
paid to appropriate choice of research project for a given undergraduate,
taking into consideration the background, skills, and interests of the
student.
Initiating and sustaining undergraduate research at predominantly undergraduate
institutions and community colleges can be particularly challenging.
At predominantly undergraduate institutions, one difficulty is the relatively
rapid turnover of student researchers, especially if they don’t begin
their research until late in their undergraduate careers. Because they
have fewer peers for interaction, faculty at smaller institutions often
find the generation of research ideas that are relevant and interesting
more difficult. Faculty at smaller institutions also tend to have heavier
teaching loads than faculty at larger, research-oriented institutions
and so have less time available for supervising student research. Lack
of institutional support is also problematic in many cases both in terms
of financial support for the necessary research infrastructure and also
in terms of administrative buy-in that research is a central component
of the undergraduate educational portfolio. This latter problem is particularly
acute at community colleges, an environment in which “teaching” is viewed
as the primary mission with the implicit model of classroom lecturing
as the expected manifestation. Technical assistance for the maintenance
of departmental instrumentation and for student training on that instrumentation
is frequently lacking at smaller institutions and community colleges.
Regardless of institution size, institutional buy-in at all levels must
be promoted with sensitivity to the nature and history of the individual
institution. Such buy-in can be promoted by means of both downward and
upward pressure: downward by administration in terms of recognition of
teaching credit for mentoring undergraduate research, and upward by faculty
in terms of structuring tenure and promotion documents to emphasize contributions
in the mentoring of undergraduate research as significant educational
contributions. Participants did note, however, that while institutional
buy-in involves promotion of research across the curriculum, different
disciplines have different definitions of what constitutes research and
the resources that are required to support it (e.g., research in English
is very different from chemistry research). It is clear that “one size
does not fit all” when it comes to undergraduate research programs. Needs
are very diverse, so flexibility is needed in defining undergraduate
research programs. Any model adopted by a particular institution should
be “win/win,” offering students the best possible educational experience
and recognizing, rewarding, and supporting faculty efforts to mentor
students.
