Mote Marine Laboratory serves as the lead institution on the National Science Foundation funded Louis Stokes Alliance for Minority Participation: Marine Science Laboratory Alliance Center of Excellence (MarSci-LACE). The goal of this innovative Center of Excellence is to understand the impact of marine STEM undergraduate research experiences, specifically those conducted at non-academic, independent research institutions. The Center considers not only undergraduate students’ learning but also psychosocial factors, career aspirations, the impacts of the approaches and perspectives of mentors, institutional support of student learning, and mentor skill development. Through this project, a number of resources have been developed, including the MarSci-LACE Mentor Development Workshop, an Intern Resource Guide and website, a Mentor Resource Guide, and intern recruitment materials.

Acquisition of a single crystal x-ray diffractometer for structure determination and diffuse scattering on small molecules, macromolecules, and materials
With NSF MRI support, we have recently purchased a dual source single crystal diffractometer equipped with a high resoln. detector. The purpose of this presentation is to publicize the new instrument and we seek users in the Southeast to maximize the pos. impact of this instrument on research efforts in the Southeastern US. Users at primarily undergraduate institutions and historically black colleges and universities are particularly encouraged to use this new resource. In general, an X-ray diffractometer allows accurate and precise measurements of the full three-dimensional structure of a mol., including bond distances and angles, and provides accurate information about the spatial arrangement of a mol. relative to neighboring mols. The studies described here impact many areas, including org. and inorg. chem., materials chem. and biochem. This instrument is an integral part of teaching as well as research and research training of graduate and undergraduate students in chem. and biochem. at this institution and at partner institutions. This poster will describe some examples of how the new diffractometer will enhance research in inorg. chem., materials chem. (via diffuse scattering), and biochem.

This work-in-progress paper presents emerging results from a research study aiming to develop and gather validity evidence for an instrument that can be used by college administrators and student-support practitioners to assess the magnitude of undergraduate students’ perceived institutional support received in science, technology, engineering, and mathematics (STEM). Our goal is to provide stakeholders with a validated tool to diagnose areas of strength and opportunities to better support students, particularly those from underserved populations. Over the past year, we have engaged in a systematic process of instrument development. We began by developing a prototype based on the newly developed Model of Co-Curricular Support (MCCS). We refined it by reviewing existing literature and instruments germane to student support, and soliciting stakeholder feedback. During the spring of 2018, we distributed the instrument to STEM undergraduate students at three U.S. institutions. In this paper, we report our process of instrument development and preliminary results. These results will inform the next revision of our instrument, ultimately providing the STEM education community with novel and theory-based ways to measure students’ perceptions of support in STEM.more » « less

In crystallographic texture analysis, ensuring that sample directions are preserved from experiment to the resulting orientation distribution is crucial to obtain physical meaning from diffraction data. This work details a procedure to ensure instrument and sample coordinates are consistent when analyzing diffraction data with a Rietveld refinement using the texture analysis softwareMAUD. A quartz crystal is measured on the HIPPO diffractometer at Los Alamos National Laboratory for this purpose. The methods described here can be applied to any diffraction instrument measuring orientation distributions in polycrystalline materials.more » « less

ABSTRACT A virtual X-Ray Laboratory for Materials Science and Engineering has been developed and used as a flexible and powerful tool to help undergraduate and graduate students become familiar with the design and operation of the X-ray equipment in visual and interactive ways in order to learn fundamental principles underlying X-ray analytical methods. The virtual equipment and lab assignments have been used for: (i) authentic online experimentation, (ii) homework and control assignments with traditional and blended courses, (iii) preparing students for hands-on work in physical X-ray labs, (iv) lecture demonstrations, and (v) performance-based assessment of students’ ability to apply gained theoretical knowledge for operating actual equipment and solving practical problems. Students have also used the virtual diffractometer linked and synchronized with an actual powder diffractometer for blended experimentation. Using the associated learning and content management system (LCMS) and authoring tools, instructors kept track of students’ performance and designed new virtual experiments and more personalized learning assignments for students. The lab has also been integrated with the MITx course available on the massive open online course edX platform for Massachusetts Institute of Technology for undergraduate students.more » « less

With increasing demands for high performance in structural systems, Smart Structures Technologies (SST), which includes advanced sensing, modern control, smart materials, optimization and novel testing, is receiving considerable attention as it has the potential to transform many fields in engineering, including civil, mechanical, aerospace, and geotechnical engineering. Currently, there is a significant gap between the engineering science with fundamental research in academia and engineering practice with potential application in the industry. To respond to this challenge, San Francisco State University and the University of South Carolina will collaborate with industrial partners to establish a Research Experiences for Undergraduates (REU) Site program, focusing on academia-industry collaborations in SST. This REU program will train undergraduate students to serve as the catalysts to facilitate the research infusion between academic and industrial partners. This student-driven joint venture between academia and industry will establish a virtuous circle for knowledge exchange and contribute to advancing both fundamental research and implementation of SST. The program will feature: formal training, workshops, and supplemental activities in the conduct of research in academia and industry; innovative research experience through engagement in projects with scientific and practical merits in both academic and industrial environments; experience in conducting laboratory experiments; and opportunities to present the research outcomes to the broader community at professional settings. This REU program will provide engineering undergraduate students a unique research experience in both academic and industrial settings through cooperative research projects. Experiencing research in both worlds is expected to help students transition from a relatively dependent status to an independent status as their competence level increases. The joint efforts among two institutions and industry partners provide the project team with extensive access to valuable resources, such as expertise to offer a wider-range of informative training workshops, advanced equipment, valuable data sets, experienced undergraduate mentors, and professional connections, that will facilitate a meaningful REU experience. Recruitment of participants will target 20 collaborating minority and primarily undergraduate institutions (15 of them are Hispanic-Serving Institutions, HSI) with limited science, technology, engineering, and mathematics (STEM) research capabilities. The model developed through this program may help to exemplify the establishment of a sustainable collaboration model between academia and industry that helps address the nation's need for mature, independent, informed, and globally competitive STEM professionals and is adapted to other disciplines. In this poster, the details of the program will be described. The challenges and lesson-learned on the collaboration between the two participating universities, communications with industrial partners, recruitment of the students, set up of the evaluation plans, and development of the program will be discussed.more » « less
