This report presents a summary of a meeting on assessment of course-based undergraduate research experiences (CUREs), including an operational definition of a CURE, a summary of research on CUREs, relevant findings from studies of undergraduate research internships, and recommendations for future research on and evaluation of CUREs.
All that remains to be said refers to the utility of the visualizing faculty, and may be compressed into a few words. A visual image is the most perfect form of mental representation wherever the shape, position, and relations of objects in space are concerned.... The pleasure its use can afford is immense.... Our bookish and wordy education tends to repress this valuable gift of nature. A faculty that is of importance in all technical and artistic occupations, that gives accuracy to our perceptions, and justness to our generalizations, is starved by lazy disuse, instead of being cultivated judiciously in such a way as will on the whole bring the best return.
Faculty perspectives of the undergraduate chemistry laboratory were the focus of a study to articulate the goals, strategies, and assessments used in undergraduate teaching laboratories. Data were collected via semistructured interviews with faculty (N = 22) from community colleges, liberal arts colleges, comprehensive universities, and research institutions engaged in teaching or supervising undergraduate laboratories. The goals for general chemistry, organic chemistry, and upper-division laboratories are described and compared among faculty who have received NSF-CCLI (now called NSF-TUES) grants to implement changes in laboratory and those who have not. Problems and limitations to success in laboratory are also reported, and the impact of these obstacles on student achievement and laboratory curricula is discussed.
Little research exists on college
students’ learning goals
in chemistry, let alone specifically pertaining to laboratory coursework.
Because students’ learning goals are linked to achievement
and dependent on context, research on students’ goals in the
laboratory context may lead to better understanding about the efficacy
of lab curricula. This study characterized undergraduate students’
learning goals for general chemistry laboratory coursework by recording
video of students completing laboratory experiments and interviewing
the students about their experiences. The data was analyzed utilizing
the framework of learning domains as described by Human Constructivism.
Students were found to be primarily guided by affective goals, such
as the desire to feel good by completing the requirements and getting
done early. This stood in conflict with any psychomotor or cognitive
goals they held concurrently. The data provide suggestions for reform
of the general chemistry laboratory curriculum.
This
work reports the development of a survey for laboratory goals in undergraduate
chemistry, the analysis of reliable and valid data collected from
a national survey of college chemistry faculty, and a synthesis of
the findings. The study used a sequential exploratory mixed-methods
design. Faculty goals for laboratory emerged across seven factors,
four of whichresearch experience, group work, error analysis,
and laboratory writingshowed significant differences by course
type. Significant differences between goals were also discovered when
analyzed by external funding for the laboratory versus no funding.
Synthesis across the previously published qualitative study and the
quantitative study reported herein yields areas of emphasis in the
curriculum for specific goals. This work adds weight to the growing
body of global literature that implores faculty to define and assess
their goals for laboratory.
Forty chemistry faculty from American Chemical Society-approved
departments were interviewed to determine their goals for undergraduate
chemistry laboratory. Faculty were stratified by type of institution,
departmental success with regard to National Science Foundation funding
for laboratory reform, and level of laboratory course. Interview transcripts
that were coded and analyzed using the lens of meaningful learning
reveal the importance of cognitive and psychomotor goals relative
to affective learning, particularly in organic chemistry and upper-division
chemistry laboratory courses. This research reveals that the undergraduate
chemistry laboratory offers multiple opportunities for faculty to
articulate learning goals across the cognitive, affective, and psychomotor
domains. Furthermore, these goals are accessible across the undergraduate
chemistry curriculum from general chemistry through organic chemistry
and into a wide array of upper-division laboratories. In this study,
faculty showed a decreasing emphasis on affective goals in organic
chemistry and upper-division courses. Whether affective goals should
be a part of the organic and upper-division chemistry curriculum remains
a question for faculty to discuss.
Chemistry faculty members are highly
skilled in obtaining, analyzing,
and interpreting physical measurements, but often they are less skilled
in measuring student learning. This work provides guidance for chemistry
faculty from the research literature on multiple-choice item development
in chemistry. Areas covered include content, stem, and response construction;
item analysis; item difficulty; and item discrimination. The goal
is to help faculty construct high-quality, reliable, and valid multiple-choice
items to evaluate students’ ability to meet learning objectives
and to demonstrate proficiency in the content domain under study.
Using item-writing guidelines based upon the research literature allows
faculty to create assessments that are reliable and valid, with greater
ability to discriminate between high- and low-achieving students.
Consensus does not exist among chemists as to the essential characteristics of inquiry in the undergraduate laboratory. A rubric developed for elementary and secondary science classrooms to distinguish among levels of inquiry was modified for the undergraduate chemistry laboratory. Both peer-reviewed experiments in the literature and commercially available experiments were evaluated using the rubric, revealing a diversity of uses for the word inquiry.The modified rubric provides a valid and reliable standard of measure for chemists to examine their laboratory curriculum.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
