Finding Some Good in an Invasive Species: Introduction and Assessment of a Novel CURE to Improve Experimental Design in Undergraduate Biology Classrooms.

ABSTRACT: Reports such as Vision and Change in Undergraduate Biology Education call for integration of course-based undergraduate research experiences (CUREs) into biology curricula and less emphasis on "cookbook" laboratories. CUREs, often characterized by a single open-ended research question, allow students to develop hypotheses, design experiments, and collaborate with peers. Conversely, "cookbook" labs incentivize task completion and have pre-determined experimental outcomes. While research comparing CUREs and "cookbook" labs is growing, there are fewer comparisons among CUREs. Here, we present a novel CURE built around an invasive grass, Bromus inermis. We evaluated this CURE's effectiveness in improving students' understanding of the Vision and Change competency relating to the application of the scientific process through development and testing of hypotheses. We did so by comparing changes in pre- and posttest scores on the Experimental Design Ability Test (EDAT) between Brome CURE students and students in a concurrent CURE, SEA-PHAGES. While students in both CUREs showed improvements at the end of the semester, Brome CURE students showed a greater increase in EDAT scores than did SEA-PHAGES CURE students. Additionally, Brome CURE students had significantly higher gains in 6 of the 10 EDAT criteria. We conclude that the Brome CURE is an effective ecological parallel to the SEA-PHAGES CURE and can help students gain a meaningful understanding of Vision and Change competencies.

Project description:The benefits of mentored undergraduate research to student success, retention, and persistence in science, technology, engineering, and mathematics (STEM) have long been identified. However, many students miss out on the opportunity to engage in research often due to unfamiliarity of various research opportunities or how to approach potential research mentors. To address this, we developed a scalable online badge, Introduction to Research, that draws on aspects of the Entering Research curriculum (Branchaw, Pfund, & Rediske, 2010) to help students explore and prepare for undergraduate research in the biomedical and behavioral sciences. Students in the BUILD Training Program, part of the larger STEM BUILD at UMBC Initiative, completed the badge in conjunction with a 3-week classroom-based undergraduate research experience (CURE) before the start of their second year of undergraduate study at the University of Maryland, Baltimore County (UMBC). We were interested in investigating how this intervention, online badge plus CURE, correlated to students engaging in undergraduate research before the end of their second year at UMBC. We did this through student self-report, comparing students who had participated in the online badge plus CURE (BTP) to those who participated in neither (Control). Our data demonstrate that students who participated in the Introduction to Research Badge and CURE entered into mentored research at a significantly higher rate than students who were exposed to neither. Further, previously validated instruments of students 'research self-efficacy and science identity were used to compare how the Introduction to Research Badge and CURE may impact these two psycho-social variables. Students who participated in the Introduction to Research Badge and CURE had significantly higher gains in research self-efficacy compared to the control group. However, no change was observed in science identity for either group. Collectively, our results suggest that students who engage in the Introduction to Research Badge in combination with a CURE engage in mentored research within a year of completion at higher levels than students who engage in neither.

Project description:BackgroundRecently, flipped classrooms (FCs) have gradually been used in Chinese higher education settings. However, few studies have focused on the effects of FCs on interdisciplinary curricula. The purpose of this study was to examine the impact of an FC on the engagement, performance, and perceptions of students and on teacher-student interaction in a pharmaceutical marketing course.DesignA clustered randomized controlled study was conducted, with 137 junior-year pharmacy undergraduates using an FC serving as the intervention group, in contrast to students using lecture-based learning (LBL) as the control group. Flanders' interaction analysis system (FIAS) was used to measure teacher-student interaction, and questionnaires regarding attitudes toward and satisfaction with the teaching model were administered.ResultsThe students in the FC group scored significantly higher than those in the LBL group (88.21±5.95 vs. 80.05±5.59, t = -8.08, p = 0.000) on pharmaceutical marketing. The multiple linear regression results showed that the FC model had a significant impact on student performance (? = 8.16, p<0.0001). The percentages of teacher talk in the FC and LBL groups were 21% and 96%, respectively (?2 = 2170.274, p = 0.000); however, the percentages of student talk in the FC and LBL groups were 75% and 2.6%, respectively (?2 = 2012.483, p = 0.000). Compared with the LBL group, most students in the FC group held more positive attitudes toward the teaching model; the mean scores for the 8 attitude attributes in the FC group were significantly higher than those in the LBL group (p = 0.000). There were significant differences in the ratings of satisfaction with teacher-student interaction (p = 0.000), the students' learning attitude (p = 0.000), the teacher's preparatory work (p = 0.000), the teaching objective (p = 0.000), and the teaching effect (p = 0.000) between the two groups.ConclusionCompared with LBL methods, implementing the FC model improved student performance, increased teacher-student interaction and generated positive student attitudes toward the experience. As an effective pedagogical model, it can also stimulate pharmacy students' learning interest and improve their self-learning abilities.
