Students (like all people) have elements of both growth and fixed mindsets. We studied shifts in both types of student mindsets over three one-semester courses. We found no significant change in students’ growth mindset at the beginning of the semester compared to the end of the semester. However, students’ fixed mindsets showed a statistically significant increase from the beginning of the semester to the end of the semester. Two multilevel models were used to understand why students’ fixed mindsets may have increased 1) personal sourcesmastery goal, performance goal, and internal recognition, and 2) situational sourcesclassroom goal orientations and external recognition. Students’ endorsement of a performance goal orientation, which focuses on demonstrating competence and managing others’ perception of their abilities, increased their fixed mindset views at the end of the semester. In the model focused on situational sources, we found that students’ fixed mindset increased when they perceived their classroom environment endorsed a performance-approach goal structure and by receiving external recognition. When comparing both models, students’ fixed mindset increase was largely explained by classroom environmental sources. Specifically, students’ fixed mindsets increased when they perceived that their classroom environment valued a demonstration of competence (i.e., classroom performance-approach). Being recognized as an engineer by peers and instructors also increased students’ fixed views of their abilities. Conversely, one situational source was found to decrease students’ fixed mindset views, i.e., a classroom environment that promotes mastery goals. Our study points to an apparent and crucial role engineering classroom environments have in promoting certain mindsets. The study concludes with one pedagogical strategy that may help mitigate the inadvertent promotion of a fixed mindset, e.g., a mastery learning pedagogical intervention. 

This is a board presentation at the 2023 ASEE Annual Conference describing the HSI Implementation and Evaluation Project: Commitment to Learning Instilled by Mastery-Based Undergraduate Program (CLIMB-UP). Commitment to Learning Instilled by a Mastery-Based Undergraduate Program (CLIMBUP) is an NSF IUSE:HSI project centered on re-designing courses with high non-completion rates (C- or lower) that have implications towards students’ graduation, transfer ability and retention. Despite decades of effort to create active, inquiry-based learning practices in classrooms, our institution continues to see equity gaps and many required courses with noncompletion rates exceeding 50%. Grading practices have been identified as one of the main culprits in the persistence of equity gaps. As a Hispanic Serving Institution, we recognize and value the diversity of experience that our students bring to our campuses and are committed to utilizing their strengths by creating datadriven, equitable grading practices that give students space to take risks and bring alternative viewpoints to our classrooms and be rewarded. We believe a Mastery-Based Grading (MBG) approach can address problems that a traditional grading approach has caused. The CLIMB-UP project is building the infrastructure to support and train STEM faculty (both tenure-line and adjuncts) to redesign and teach a Mastery-Based Graded (MGB) course, and is conducting research on faculty experiences and on the change in student attitudes, mindsets, and outcomes. 

A 2019 report from the National Academies on Minority Serving Institutions (MSIs) concluded that MSIs need to change their culture to successfully serve students with marginalized racial and/or ethnic identities. The report recommends institutional responsiveness to meet students “where they are,” metaphorically, creating supportive campus environments and providing tailored academic and social support structures. In recent years, the faculty, staff, and administrators at California State University, Los Angeles have made significant efforts to enhance student success through multiple initiatives including a summer bridge program, first-year in engineering program, etc. However, it has become clear that more profound changes are needed to create a culture that meets students “where they are.” In 2020, we were awarded NSF support for Eco-STEM, an initiative designed to change a system that demands "college-ready" students into one that is "student-ready." Aimed at shifting the deficit mindset prevailing in engineering education, the Eco-STEM project embraces an asset-based ecosystem model that thinks of education as cultivation, and ideas as seeds we are planting, rather than a system of standards and quality checks. This significant paradigm and culture transformation is accomplished through: 1) The Eco-STEM Faculty Fellows’ Community of Practice (CoP), which employs critically reflective dialogue[ ][ ] to enhance the learning environment using asset-based learner-centered instructional approaches; 2) A Leadership CoP with department chairs and program directors that guides cultural change at the department/program level; 3) A Facilitators’ CoP that prepares facilitators to lead, sustain, update, and expand the Faculty and Leadership CoPs; 4) Reform of the teaching evaluation system to sustain the cultural changes. This paper presents the progress and preliminary findings of the Eco-STEM project. During the first project year, the project team formulated the curriculum for the Faculty CoP with a focus on inclusive pedagogy, community cultural wealth, and community building, developed a classroom peer observation tool to provide formative data for teaching reflection, and designed research inquiry tools. The latter investigates the following research questions: 1) To what extent do the Eco-STEM CoPs effectively shift the mental models of participants from a factory-like model to an ecosystem model of education? 2) To what extent does this shift support an emphasis on the assets of our students, faculty, and staff members and, in turn, allow for enhanced motivation, excellence and success? 3) To what extent do new faculty assessment tools designed to provide feedback that reflects ecosystem-centric principles and values allow for individuals within the system to thrive? In Fall 2021, the first cohort of Eco-STEM Faculty Fellows were recruited, and rich conversations and in-depth reflections in our CoP meetings indicated Fellows’ positive responses to both the CoP curriculum and facilitation practices. This paper offers a work-in-progress introduction to the Eco-STEM project, including the Faculty CoP, the classroom peer observation tool, and the proposed research instruments. We hope this work will cultivate broader conversations within the engineering education research community about cultural change in engineering education and methods towards its implementation. 

With support from NSF Scholarships in Science, Technology, Engineering, and Mathematics (S-STEM), the Culturally Adaptive Pathway to Success (CAPS) program aims to build an inclusive pathway to accelerate the graduation for academically talented, low-income students in Engineering and Computer Science majors at [University Name], which traditionally serves the underrepresented and educationally disadvantaged minority students in the [City Name area]. CAPS focuses on progressively developing social and career competence in our students via three integrated interventions: (1) Mentor+, a relationally informed advising strategy that encourages students to see their academic work in relation to their families and communities; (2) peer cohorts, providing social support structure for students and enhancing their sense of belonging in engineering and computer science classrooms and beyond; and (3) professional development from faculty who have been trained in difference-education theory, so that they can support students with varying levels of understanding of the antecedents of college success. To ensure success of these interventions, the CAPS program places great emphasis on developing culturally responsive advisement methods and training faculty mentors to facilitate creating a culture of culturally adaptive advising. This paper presents the CAPS progress in the past two project years. In particular, we will share several changes that we have made after the first project year to improve several key components of the program - recruitment, cohort building, and mentor training. The program strengthened the recruitment by actively involving scholars and faculties in reaching out to students and successfully recruited more scholars for the second cohort (16 scholars) than the first cohort (12 scholars). Also, the program has initiated new activities for peer-mentoring and cohort gathering within each major. As continuous development of the mentor training, the program has added a training session focusing on various aspects of intersectionality as it relates to individual’s social identities, and how mentors can use these knowledge to better interact with mentees. In addition to these changes, we will also report findings on how the program impacted on scholars’ academic growth and mentors’ understanding about the culturally adaptive advisement to answer the CAPS research questions (a) how these interventions affect the development of social belonging and engineering identity of CAPS scholars, and (b) the impact of Mentor+ on academic resilience and progress to degree. The program conducted qualitative data collection and analysis via focus group meetings and interviews as well as quantitative data collection and analysis using academic records and surveys. Our findings will help enhance the CAPS program and establish a sustainable Scholars Support Program at the university, which can be implemented with scholarships funded by other sources, and which can be transferred to similar culturally diverse institutions to increase success for students who have socio-economic challenges. 

The financial disadvantage of many students in the College of Engineering, Computer Science, and Technology (ECST) at California State University, Los Angeles, is often in parallel with inadequate academic preparation through K-12 education and limited family guidance. Hence, many students, including those who are academically-talented, experience significant challenges in achieving their academic goals. In 2018, the College of ECST received an award from NSF SSTEM program to establish a Culturally Adaptive Pathway to Success (CAPS) program that aims to build an inclusive pathway to accelerate the graduation for academically talented, lowincome students in Engineering and Computer Science majors. CAPS focuses on progressively developing students’ social and career competence via three integrated interventions: (1) Mentor+, relationally informed advising that encourages students to see their academic work in relation to their families and communities; (2) peer cohorts, providing social support structure for students and enhancing their sense of belongings in engineering and computer science classrooms and beyond; and (3) professional development with difference-education, illuminating the hidden curricula that may disadvantage first-generation and low income students. This paper presents our progress and core program activities during the first year of the CAPS program, including the recruitment process and mentor training program. In Fall 18, group and individual mentoring sessions have taken place following the culturally responsive mentoring strategy. In addition to program activities, the paper will also share the data collected through focus groups and report the lessons learned during the first-year implementation phase. 

Phytoplankton and associated microbial communities provide organic carbon to oceanic food webs and drive ecosystem dynamics. However, capturing those dynamics is challenging. Here, an in situ, semi-Lagrangian, robotic sampler profiled pelagic microbes at 4 h intervals over ~2.6 days in North Pacific high-nutrient, low-chlorophyll waters. We report on the community structure and transcriptional dynamics of microbes in an operationally large size class (>5 μm) predominantly populated by dinoflagellates, ciliates, haptophytes, pelagophytes, diatoms, cyanobacteria (chiefly Synechococcus), prasinophytes (chiefly Ostreococcus), fungi, archaea, and proteobacteria. Apart from fungi and archaea, all groups exhibited 24-h periodicity in some transcripts, but larger portions of the transcriptome oscillated in phototrophs. Periodic photosynthesis-related transcripts exhibited a temporal cascade across the morning hours, conserved across diverse phototrophic lineages. Pronounced silica:nitrate drawdown, a high flavodoxin to ferredoxin transcript ratio, and elevated expression of other Fe-stress markers indicated Fe-limitation. Fe-stress markers peaked during a photoperiodically adaptive time window that could modulate phytoplankton response to seasonal Fe-limitation. Remarkably, we observed viruses that infect the majority of abundant taxa, often with total transcriptional activity synchronized with putative hosts. Taken together, these data reveal a microbial plankton community that is shaped by recycled production and tightly controlled by Fe-limitation and viral activity.
