It is well known that learning occurs best when students are engaged with a topic that interests them or has relevance for important aspects of their lives. In coastal California, the health of the ocean is a serious local concern, and ocean plastics are ubiquitous. We have developed a course‐based undergraduate research experience (CURE) on an existing research project addressing microbes colonizing floating plastic marine debris. The objective of the project is to increase student engagement and persistence in biology. The project (recently awarded an NSF education grant focused on Hispanic students) brings together National University (NU), an undergraduate teaching institution serving non‐traditional students, with Scripps Institution of Oceanography (SIO), a world‐renowned research‐oriented institution at UC San Diego. A modular design allows students from different biology courses (both non‐majors and majors) to participate in field and laboratory research while also interacting with research scientists and graduate students. Module contents range from classroom material including experimental design, hypothesis testing, and data analysis, to laboratory activities such as deployment of test materials, microbiology and molecular biology techniques, as well as bioinformatics. Assessment of the project involves surveys and focus groups to evaluate student engagement, as well as institutional metrics such as retention in the BS Biology program. A pilot involving a non majors general biology course visiting SIO was well‐received by students. Currently (November 2018) an extended intervention is underway with a majors general biology course. During the first week of class students learned about the research project via video material and class lectures. A half day visit to SIO provided them with field trip experience, laboratory activities, presentation about plastic research, and interactions with scientists and graduate students. In successive laboratory activities, students observed colony morphology, performed Gram stainings and colony PCR, practiced Blast searches and developed simple phylogenetic trees. We conclude that the framework can be successfully implemented in spite of time and logistical challenges. We anticipate implementing and disseminating this CURE as a widely applicable model for biology and ocean science education centered on contemporary topics of immediate interest to students.

Abstract The drive to broaden equitable access to undergraduate research experiences has catalyzed the development and implementation of course‐based undergraduate research experiences (CUREs). Biology education has prioritized embedding CUREs in introductory labs, which are frequently taught by graduate teaching assistants (GTAs). Thus, a CURE GTA is expected not only to teach but also to support novice student researchers. We know little about how GTAs perform as research mentors in a CURE, or how the quality of their mentorship and support impacts undergraduate students. To address this gap in knowledge, we conducted a phenomenological study of an introductory biology CURE, interviewing 25 undergraduate students taught by nine different GTAs at a single institution. We used self‐determination theory to guide our exploration of how students' autonomous motivation to engage in a CURE is impacted by perceptions of GTA support. We found that highly motivated students were more likely to experience factors hypothesized to optimize motivation in the CURE, and to perceive that their GTA was highly supportive of these elements. Students with lower motivation were less likely to report engaging in fundamental elements of research offered in a CURE. Our findings suggest that GTAs directly impact students' motivation, which can, in turn, influence whether students perceive receiving the full research experience as intended in a CURE. We contend that practitioners who coordinate CUREs led by GTAs should therefore offer curated training that emphasizes supporting students' autonomous motivation in the course and engagement in the research. Our work suggests that GTAs may differ in their capacity to provide students with the support they need to receive and benefit from certain pedagogical practices. Future work assessing innovative approaches in undergraduate biology laboratory courses should continue to investigate potenital differential outcomes for students taught by GTAs.

Course-based undergraduate research experiences (CUREs) are a promising approach for incorporating inquiry-based instruction into the under- graduate chemistry laboratory curriculum. This study used data from a national survey of inorganic chemistry faculty members (n = 142) to investigate CURE implementation in the inorganic chemistry instructional laboratory. Results indicate that faculty members who implement CUREs place greater emphasis on a distinct set of instructional goals when compared to faculty members who do not implement CUREs. CURE implementation was further associated with a range of instructional and departmental characteristics, including group-only student work, independent course development by faculty instructors, limited graduate TA support, and ACS certification of degree programs. Findings from this investigation point toward (1) a need for increased efforts focused on supporting CURE implementation, (2) productive avenues through which curriculum designers and communities of practice can provide this support, and (3) needed areas of research that will further inform these efforts.more » « less

Long, Tammy (Ed.)One critical step in the challenging process of curricular reform is determining how closely a curriculum aligns with national recommendations. Here, we examine the alignment of teaching, assessment, and student experience in undergraduate biology courses with the Vision and Change core competency recommendations. We applied the intended–enacted–experienced curriculum model to obtain a more complete, multiperspective view of the curriculum. First, we developed and piloted the BioSkills Curriculum Survey with more than 100 biology instructors across five institutions. Using multilevel logistic regression modeling of the survey data, we found that instructors were equally likely to report teaching all competencies; however, they reported assessing some competencies more than others. After adding course characteristics to our model, we found that the likelihood of teaching certain competencies depended on course type. Next, we analyzed class materials and student perceptions of instruction in 10 biology courses in one department. Within this smaller sample, we found that instructors messaged a narrower range of competency learning outcomes on their syllabi than they reported teaching on the survey. Finally, modeling revealed that inclusion of an outcome on assessments, but not syllabi, increased the likelihood that students and their instructor agreed whether it was taught.more » « less

This complete research paper details an investigation into the influence of instructors' pedagogical knowledge on their classroom practices in the context of teaching first-year engineering courses. Background and Motivation: First-year engineering courses serve as the foundational setting in which students are introduced to the field of engineering as well as the pedagogies specific to engineering teaching and learning. These courses are pivotal in equipping students with essential knowledge and skills, setting the stage for their success in more advanced engineering topics. Understanding how instructors' pedagogical knowledge affects their teaching practices is crucial. Pedagogical knowledge encompasses a wide range of techniques to effectively manage a classroom and engage students. This includes the use of instructional strategies that cater to diverse student needs, the design of impactful and engaging lesson plans, etc. There is, however, limited research on how instructors’ pedagogical knowledge influences their classroom practices in first-year engineering courses. Hence, it seems opportune and essential to conduct additional research on engineering instructors' classroom practices. Research Question: The central question driving this research is: How does instructors' pedagogical knowledge influence their pedagogical practices for first-year engineering courses? Method: For this study, we chose the model of teacher professional knowledge and skill (TPK&S) that includes pedagogical content knowledge (PCK). The model recognizes the fundamental importance of pedagogical knowledge and contextualizes PCK within that framework, encompassing the intricate nature of teaching and learning. A descriptive case study was utilized as a methodology for this work to delve into the phenomenon. The context of the study was a first-year introductory engineering course offered at a large public research institution. This is a pilot study for an NSF-funded project (blinded for review), the study involved two instructors, Chandler and Joey (pseudonyms), chosen through purposive sampling, with varying levels of teaching experience. Data collection involved direct classroom observation using the Teaching Dimensions Observation Protocol (TDOP) and semi-structured interviews conducted after the observations. The interviews were conducted after classroom observations, allowing the researcher to explore specific findings from the observations. Results: Thematic analysis was used to categorize the data based on the constructs of the theoretical framework. The analysis revealed three major themes: (a) Instructors' topic-specific professional knowledge significantly influences their pedagogical practices. Both instructors adapt their teaching methods based on their understanding of course material and students' difficulties. (b) The interaction between instructors' personal pedagogical content knowledge (PCK) and the classroom context shapes their classroom practices. (c) Instructors' beliefs and prior knowledge act as amplifiers or filters based on the situation. They filter out their teaching practices that do not align with their beliefs and prior knowledge. Conclusion: The findings presented in this paper provide valuable insights into the complex interplay between instructors' pedagogical knowledge and their classroom practices. This work holds significant implications for current and future first-year instructors in that this paper will showcase how instructors use their understanding of the content and their students to teach, which is a critical aspect of helping students successfully integrate into engineering.more » « less
