Course-based undergraduate research experiences (CUREs) are laboratory courses that integrate broadly relevant problems, discovery, use of the scientific process, collaboration, and iteration to ...provide more students with research experiences than is possible in individually mentored faculty laboratories. Members of the national Malate dehydrogenase CUREs Community (MCC) investigated the differences in student impacts between traditional laboratory courses (control), a short module CURE within traditional laboratory courses (mCURE), and CUREs lasting the entire course (cCURE). The sample included approximately 1,500 students taught by 22 faculty at 19 institutions. We investigated course structures for elements of a CURE and student outcomes including student knowledge, student learning, student attitudes, interest in future research, overall experience, future GPA, and retention in STEM. We also disaggregated the data to investigate whether underrepresented minority (URM) outcomes were different from White and Asian students. We found that the less time students spent in the CURE the less the course was reported to contain experiences indicative of a CURE. The cCURE imparted the largest impacts for experimental design, career interests, and plans to conduct future research, while the remaining outcomes were similar between the three conditions. The mCURE student outcomes were similar to control courses for most outcomes measured in this study. However, for experimental design, the mCURE was not significantly different than either the control or cCURE. Comparing URM and White/Asian student outcomes indicated no difference for condition, except for interest in future research. Notably, the URM students in the mCURE condition had significantly higher interest in conducting research in the future than White/Asian students.

Course‐based Undergraduate Research Experiences (CUREs) offer an inclusive means to engage students in the scientific process and enhance student learning gains and persistence in STEM. To realize ...the benefits of CURE implementation, is there a minimum length of CURE? We studied the learning and attitudinal outcomes of more than 1,000 undergraduate students across the United States involved in chemistry, biochemistry, and molecular biology CUREs using malate dehydrogenase as the model system. There were three conditions, complete semester CURE (cCURE), modular CURE of about six weeks in length embedded into a laboratory course (mCURE), and no CURE (control). We also looked at the impact these conditions had on students who are persons excluded from STEM due to ethnicity or race (PEER). We hypothesized that the longer the students spent in a CURE the better their outcomes. We measured student outcomes using several validated measures and compared the conditions using ANOVA, ANCOVA, and chi‐square analyses. We found cCURE students had higher experimental design learning and STEM support than control students. We found cCURE>mCURE>control for student’s report of their interest in conducting research in the future, support for STEM students, and their interest in a STEM career. Students in the cCURE and control had higher positive attitudes about scientific research than students in the mCURE. There were no differences between conditions for negative attitudes towards science, science literacy, and beliefs about learning science. We found PEER students reporting the same results as White/Asian students, except for their interest in conducting research: PEER students in mCUREs had higher interest than their White/Asian counterparts in conducting research. We conclude that the overall pattern was for students in the cCURE condition to have better learning and attitudinal outcomes than students in the mCURE and control conditions. Additionally, PEER student outcomes in CURE conditions were similar to their White/Asian counterparts. These results should encourage faculty to use CUREs in laboratory courses to improve all students’ outcomes and indicate that even a short CURE embedded within a traditional laboratory course can benefit students.
Course-based undergraduate research experiences (CUREs) incorporate authentic research instead of confirmatory exercises into laboratory courses. Following the COVID-19 pandemic, there has been a ...general shift in instructional modalities from face-to-face (F2F) towards hybrid and online teaching. Student impacts caused by the abrupt shift to online teaching have been characterized, but comparisons between modalities for CUREs are missing. Therefore, we evaluated student learning and attitudinal outcomes in F2F, hybrid, and online delivery of an introductory college biology CURE. Additionally, we compared student outcomes between White/Asian students and persons excluded due to ethnicity or race (PEER) in these modalities. There were significant learning differences between modalities, but there were no significant learning differences by PEER status. Of six attitudinal variables, one varied significantly by modality and three varied significantly for PEER students. These results suggest that CUREs can be adapted to the online or hybrid modality with minimal impacts on student outcomes.
One major implication of the Next Generation Science Standards is the need to integrate inquiry and practice and incorporate engineering into science education. To support teachers' change efforts in ...a time of heightened science, technology, engineering, and mathematics standards for all students, effective professional development (PD) is critical. However, rural schools face significant challenges in accessing PD. Distance-based instructional coaching (DBIC) has emerged as a potential solution for implementing highly interactive, sustainable models of teacher support in rural areas. The present study was conducted within a larger study that examined the efficacy of a summer PD with follow-up DBIC on rural teachers' knowledge, self-efficacy, and classroom practice of a guided science inquiry instructional approach. This study drew on empirical data using an in-depth analysis of a single case with a rural middle school science teacher, "Kara," whose unique teaching schedule allowed for an examination of changes in her science inquiry instructional practice. In the present study, Vygotsky space provided insight into the process of the teacher's learning as appropriation, transformation, and publication through the events observed. Showing the impact of DBIC on teacher PD and for facilitating improved student outcomes, this study has potential implications for educational policy, pedagogical practice, and meeting nationwide educational standards. In addition, DBIC maintains the integrity of the coaching model while simultaneously enhancing the feasibility of coaching for rural or remote educational systems and schools.
Within the past decade, course-based undergraduate research experiences (CUREs) have emerged as a viable mechanism to enhance novices' development of scientific reasoning and process skills in the ...science, technology, engineering, and mathematics disciplines. Recent evidence within the bioeducation literature suggests that student engagement in such experiences not only increases their appreciation for and interest in scientific research but also enhances their ability to "think like a scientist." Despite these critical outcomes, few studies have objectively explored CURE versus non-CURE students' development of content knowledge, attitudes, and motivation in the discipline, particularly among nonvolunteer samples. To address these concerns, we adopted a mixed-methods approach to evaluate the aforementioned outcomes following implementation of a novel CURE in an introductory cell/molecular biology course. Results indicate that CURE participants exhibited more expert-like outcomes on these constructs relative to their nonCURE counterparts, including in those areas related to self-efficacy, self-determination, and problem-solving strategies. Furthermore, analysis of end-of-term survey data suggests that select features of the CURE, such as increased student autonomy and collaboration, mediate student learning and enjoyment. Collectively, this research provides novel insights into the benefits achieved as a result of CURE participation and can be used to guide future development and evaluation of authentic research opportunities.

In response to calls for reform in undergraduate biology education, we conducted research examining how varying active-learning strategies impacted students' conceptual understanding, attitudes, and ...motivation in two sections of a large-lecture introductory cell and molecular biology course. Using a quasi-experimental design, we collected quantitative data to compare participants' conceptual understanding, attitudes, and motivation in the biological sciences across two contexts that employed different active-learning strategies and that were facilitated by unique instructors. Students participated in either graphic organizer/worksheet activities or clicker-based case studies. After controlling for demographic and presemester affective differences, we found that students in both active-learning environments displayed similar and significant learning gains. In terms of attitudinal and motivational data, significant differences were observed for two attitudinal measures. Specifically, those students who had participated in graphic organizer/worksheet activities demonstrated more expert-like attitudes related to their enjoyment of biology and ability to make real-world connections. However, all motivational and most attitudinal data were not significantly different between the students in the two learning environments. These data reinforce the notion that active learning is associated with conceptual change and suggests that more research is needed to examine the differential effects of varying active-learning strategies on students' attitudes and motivation in the domain.

This study investigated the impact of a summer institute with follow-up coaching (treatment) versus no professional development (control) on middle and high school teacher and student science ...practice outcomes. Treatment teachers participated in a 2-week summer institute that used evidence-based professional development practices followed by remotely delivered instructional coaching led by project-based science coaches over 6-8 weeks during the school year. Results from 124 teachers across 110 schools showed significant differences between treatment and control groups for teacher science practice knowledge, performance, beliefs, and self-efficacy and student science practice skills and self-efficacy. Teacher effect sizes for the combined summer institute plus coaching (treatment) across all dependent variables ranged from 0.67 to 1.37. Student comparisons showed higher science practice performance for the treatment group; effect sizes were 0.39 for high school and 0.34 for middle school. Results demonstrated significantly higher increases in student self-efficacy for the treatment compared to the control group, and this increased self-efficacy was sustained through the end of the school year. Results substantiate the value of combining coaching with a summer institute to support teacher growth and development, with the summer institute providing foundational knowledge and fostering teacher self-efficacy to effectively implement newly learned instructional practices. The coaching in turn built on that foundation and provided needed support for teachers to transfer knowledge and skills to classroom practice.
