A course-based undergraduate research experience investigating the consequences of nonconserved mutations in lactate dehydrogenase

ABSTRACT A course-based undergraduate research experience (CURE) was designed to integrate key microbiological principles and techniques into an authentic research experience in a classroom setting and was implemented in an undergraduate microbiology laboratory course. Students conducted a 6-week study in order to determine the identity and quantity of unique probiotic species from various types of kefir. This course module followed an inquiry-based pedagogical approach in which students use the scientific process to investigate an unknown question with no predetermined outcome. During each lab, relevant microbiological topics and laboratory concepts were presented. Students then performed various laboratory techniques, reinforcing the lecture material with hands-on experience. In addition, students participated in reflection through group presentation of their results, bioinformatic analysis and literature review. Based on data collected from pre- and post-study survey responses, both student knowledge and attitudes towards the topics covered improved due to participation in this CURE. Importantly, this CURE can be implemented at many levels of education, requiring only minimal resources and common laboratory equipment.

The Impact

Opportunities for large numbers of undergraduates to engage in authentic research experiences are limited in many large public institutions. These large public institutions serve the vast majority of students who are historically underrepresented in STEM fields, such as first-generation, low-income students of color. Although a course-based undergraduate research experience (CURE) is one scalable approach to providing such opportunities, there is limited evidence about the impact of participation, particularly for students historically underrepresented in science. This study provides evidence of the influence of student participation in a CURE on undergraduate science course grades using an experimental design and multiple years of data from students at a Hispanic-serving institution. Course grades were compared for five different science courses across five cohorts of students participating in a CURE ( n = 935) and a similar group of students who did not participate in the CURE ( n = 1,144). CURE students had significantly higher overall grades in a lecture course directly related to the CURE even after statistically adjusting for demographic and academic characteristics. Implications for CUREs as a model for improving science knowledge and achievement for students typically underrepresented in STEM fields are discussed.

Pedagogical Innovation

ABSTRACTTraditional lecture-centered approaches alone are inadequate for preparing students for the challenges of creative problem solving in the STEM disciplines. As an alternative, learnercentered and other high-impact pedagogies are gaining prominence. The Wabash College 3D Printing and Fabrication Center (3D-PFC) supports several initiatives on campus, but one of the most successful is a computer-aided design (CAD) and fabrication-based undergraduate research internship program. The first cohort of four students participated in an eight-week program during the summer of 2015. A second group of the four students was successfully recruited to participate the following summer. This intensive materials science research experience challenged students to employ digital design and fabrication in the design, testing, and construction of inexpensive scientific instrumentation for use in introductory STEM courses at Wabash College. The student research interns ultimately produced a variety of successful new designs that could be produced for less than $25 per device and successfully detect analytes of interest down to concentrations in the parts per million (ppm) range. These student-produced instruments have enabled innovations in the way introductory instrumental analysis is taught on campus. Beyond summer work, the 3D-PFC staffed student interns during the academic year, where they collaborated on various cross-disciplinary projects with students and faculty from departments such as mathematics, physics, biology, rhetoric, history, classics, and English. Thus far, the student work has led to three campus presentations, four presentations at national professional conferences, and three peer-reviewed publications. The following report highlights initial progress as well as preliminary assessment findings.
