   Vazquez_Domimguez, Max; Goodwin, Lindsay; Hardee, Sheri (February 2024, Conference of the Americas)

   Baldwin, Amy; Danns, Donna; Howe, Chad (Ed.)

   In this presentation, we will do a longitudinal comparison of science lesson plan implementations from a group of preservice teachers’ experiences during a STEM-based summer program to their experiences during their Fall semester in their practice in regular elementary and middle schools. On the one hand, their summer experiences consisted of learning and implementing science and engineering lesson plans using culturally and linguistically sustaining pedagogies, which was an intensive and guided opportunity led by university faculty on one of the university campuses. In this experience, preservice teachers collaborated with peers for 15 days to implement and evaluate their teaching of science activities in a flexible environment. On the other hand, preservice teachers have their required practice in schools during senior year to implement lesson plans and become familiar with the regular tasks of an in-service teacher. This comparison is part of the research conducted by the Culturally Sustaining Pedagogies in Science for English Language Learners project funded by the National Science Foundation and focuses on providing the necessary pedagogical tools to teach STEM to multilingual students (in our case, from Latin American countries). We conclude with a series of recommendations for preservice teachers and in-service teachers who have multilingual and emerging bilingual learners in their classrooms.

2. Engaging Nontraditional Students by CURE‐ing Microbes on Ocean Plastics

   Barral, AM (April 2019, The FASEB journal)

   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. Support or Funding Information This project is funded by the NSF‐HSI grant #1832545

3. Utilization of Remote Access Electron Microscopes to Enhance Technology Education and Foster STEM Interest in Preteen Students

   https://doi.org/10.1007/s11165-020-09964-4

   Remote access technology in STEM education fills dual roles as an educational tool to deliver science education (Educational Technology) and as a means to teach about technology itself (Technology Education). A five-lesson sequence was introduced to 11 and 12-year-old students at an urban school. The lesson sequences were inquiry-based, hands-on, and utilized active learning pedagogies, which have been implemented in STEM classrooms worldwide. Each lesson employed a scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS) accessed remotely. Students were assessed using multiple-choice questions to ascertain (1) technology education learning gains: did students gain an understanding of how electron microscopes work? and (2) educational technology learning gains: did students gain a better understanding of lesson content through use of the electron microscope? Likert-item surveys were developed, distributed, and analyzed to established how remote access technology affected student attitudes toward science, college, and technology. Participating students had a positive increase in attitudes toward scientific technology by engaging in the lesson sequences, reported positive attitudes toward remote access experiences, and exhibited learning gains in the science behind the SEM technology they accessed remotely. These findings suggest that remote experiences are a strong form of technology education, but also that future research could explore ways to strengthen remote access as an educational technology (a tool to deliver lesson content), such as one-on-one engagement. This study promotes future research into inquiry-based, hands-on, integrated lessons approach that utilize educational technology learning through remote instruments as a pedagogy to increase students’ engagement with and learning of the T in STEM.

4. First Year Experience from RET Site: High School Teacher Experience in Engineering Design and Manufacturing

   Zhu, W. (January 2022, 2022 ASEE Annual Conference & Exposition)

   In 2019, University of Houston (UH) at Houston, Texas was awarded an NSF Research Experience for Teachers (RET) site grant titled “RET Site: High School Teacher Experience in Engineering Design and Manufacturing.” The goal of the project is to host 12 high school teachers each summer to participate in engineering design and manufacturing research and then convert their experience into high school curriculum. In summer of 2021, the first cohort of 12 teachers from Region 4 of Southeast Texas participated in the RET program at UH College of Technology (COT). This six-week program, open to local high school STEM teachers in Texas, sought to advance educators’ knowledge of concepts in design and manufacturing as a means of enriching high school curriculums and meeting foundational standards set by 2013’s Texas House Bill 5. These standards require enhanced STEM contents in high school curricula as a prerequisite for graduation, detailed in the Texas Essential Knowledge and Skills standard. Due to the pandemic situation, about 50% of the activities are online and the rest are face to face. About 40% of the time, teachers attended online workshops to enhance their knowledge of topics in engineering design and manufacturing before embarking on applicable research projects in the labs. Six UH COT engineering technology professors each led workshops in a week. The four tenure-track engineering mentors, assisted by student research assistants, each mentored three teachers on projects ranging from additive manufacturing to thermal/fluids, materials, and energy. The group also participated in field trips to local companies including ARC Specialties, Master Flo, Re:3D, and Forged Components. They worked with two instructional track engineering technology professors and one professor of education on applying their learnings to lesson plan design. Participants also met weekly for online Brown Bag teacher seminars to share their experiences and discuss curricula, which was organized by the RET master teacher. On the final day of the program, the teachers presented their curriculum prototype for the fall semester to the group and received completion certificates. The program assessment was led by the assessment specialist, Director of Assessment and Accreditation at UH COT. Teacher participants found the research experience with their mentors beneficial not only to them, but also to their students according to our findings from interviews. The mentors will visit their mentees’ classrooms to see the lesson plans being implemented. In the spring of 2022, the teachers will present their refined curricula at a RET symposium to be organized at UH and submit their standards-aligned plans to teachengineering.org for other K-12 educators to access.

5. Eliciting and refining conceptions of STEM education: A series of activities for professional development

   Dare, E. A. (May 2021, Innovations in Science Teacher Education)

   Integrated STEM (science, technology, engineering, and mathematics) education is becoming increasingly common in K–12 classrooms. However, various definitions of STEM education exist that make it challenging for teachers to know what to implement and how to do so in their classrooms. In this article, we describe a series of activities used in a week- long professional development workshop designed to elicit K–12 teachers’ conceptions of STEM and the roles that science, technology, engineering, and mathematics play in STEM education. These activities not only engage teachers in conversations with peers and colleagues in a professional development setting but also enable teachers to reflect on their learning related to STEM education in the context of creating lesson plans and considering future teaching. In addition to describing these activities, we share suggestions related to how these activities may be used in venues outside of professional development.
