In pre-college levels, integrated science, technology, engineering, and mathematics (STEM) are often taught by science or mathematics teachers. These teachers lack the engineering and technology background and they do not necessarily use project-based and inquiry-oriented instructional strategies. To close the gap in the qualified STEM education teacher workforce, the authors developed and piloted a novel course to train preservice STEM teachers to effectively employ project-based and inquiry-oriented teaching strategies at pre-college levels. This 3-credit research and design experience course was piloted in the Spring 2023 semester. The preservice STEM teachers, enrolled in the course, engaged in hands-on activities, engineering project-based training, inquiry-based learning techniques through research training, makerspace training, field experience, and mentorship. The course comprised two parts. In part I, the students received research training. In part II, the students engaged in engineering design and makerspace professional development. In this paper, we report on the course design elements and the impact of the course activities on students’ self-efficacy in teaching STEM subjects using emerging technology, as well as their teaching approaches and understanding of student learning. The authors conducted a mixed methods study and collected both qualitative and quantitative data. Preliminary results of the multiyear study are presented. Initial findings indicate a heightened confidence of the students in their ability to deliver STEM content in secondary classrooms. Students improved their teaching approaches and reported positive experiences with the course.

Gene Expression and Data Analysis Pipeline Using Cancer BioPortal in the Classroom
At institutions with an emphasis on authentic research experiences as an integral part of the biology curriculum, COVID created a huge challenge for course instructors whose learning objectives were designed for such experiences. Moving such laboratory experiences online when remote learning became necessary has resulted in a new model for CUREs that utilizes free online databases to provide not only a novel research experience for students, but also the opportunity to engage in big data analysis. Cancer BioPortal (cBioPortal) is an open-access collective cancer research resource for storing and exploring clinical, genomic, proteomic, and transcriptomic data. cBioPortal eliminates the computational barrier of interpreting complex genomic data by providing easily understandable visualization that can be interpreted and translated into relevant biological insights. Because no prior computational knowledge is required, cBioPortal is an ideal educational tool for either in-person or distance learning environments. We developed a pedagogical approach, video tutorials, and data analysis workflows centered on using cBioPortal. Pedagogically, students develop an initial research outline that is continually updated and graded throughout the project. Progress during the project or course is assessed by a series of student presentations that are 5 to 15 minutes in length and are aimed at explaining the approach used in data acquisition, interpretation of the data, and relevance to the initial hypothesis. While cancer-specific, this analysis platform appeals to a wide range of classes and student interests. Further, the project has been successfully done both as an independent research experience and as part of a virtual class-based research project.

Palagi, Patricia M (Ed.)As genomics technologies advance, there is a growing demand for computational biologists trained for genomics analysis but instructors face significant hurdles in providing formal training in computer programming, statistics, and genomics to biology students. Fully online learners represent a significant and growing community that can contribute to meet this need, but they are frequently excluded from valuable research opportunities which mostly do not offer the flexibility they need. To address these opportunity gaps, we developed an asynchronous course-based undergraduate research experience (CURE) for computational genomics specifically for fully online biology students. We generated custom learning materials and leveraged remotely accessible computational tools to address 2 novel research questions over 2 iterations of the genomics CURE, one testing bioinformatics approaches and one mining cancer genomics data. Here, we present how the instructional team distributed analysis needed to address these questions between students over a 7.5-week CURE and provided concurrent training in biology and statistics, computer programming, and professional development. Scores from identical learning assessments administered before and after completion of each CURE showed significant learning gains across biology and coding course objectives. Open-response progress reports were submitted weekly and identified self-reported adaptive coping strategies for challenges encountered throughout the course. Progress reports identified problems that could be resolved through collaboration with instructors and peers via messaging platforms and virtual meetings. We implemented asynchronous communication using the Slack messaging platform and an asynchronous journal club where students discussed relevant publications using the Perusall social annotation platform. The online genomics CURE resulted in unanticipated positive outcomes, including students voluntarily discussing plans to continue research after the course. These outcomes underscore the effectiveness of this genomics CURE for scientific training, recruitment and student-mentor relationships, and student successes. Asynchronous genomics CUREs can contribute to a more skilled, diverse, and inclusive workforce for the advancement of biomedical science.more » « less

The purpose of this study is to develop an instrument to measure student perceptions about the learning experiences in their online undergraduate engineering courses. Online education continues to grow broadly in higher education, but the movement toward acceptance and comprehensive utilization of online learning has generally been slower in engineering. Recently, however, there have been indicators that this could be changing. For example, ABET has accredited online undergraduate engineering degrees at Stony Brook University and Arizona State University (ASU), and an increasing number of other undergraduate engineering programs also offer online courses. During this period of transition in engineering education, further investigation about the online modality in the context of engineering education is needed, and survey instrumentation can support such investigations. The instrument presented in this paper is grounded in a Model for Online Course-level Persistence in Engineering (MOCPE), which was developed by our research team by combining two motivational frameworks used to study student persistence: the Expectancy x Value Theory of Achievement Motivation (EVT), and the ARCS model of motivational design. The initial MOCPE instrument contained 79 items related to students’ perceptions about the characteristics of their courses (i.e., the online learning management system, instructor practices, and peer support), expectancies of course success, course task values, perceived course difficulties, and intention to persist in the course. Evidence of validity and reliability was collected using a three-step process. First, we tested face and content validity of the instrument with experts in online engineering education and online undergraduate engineering students. Next, the survey was administered to the online undergraduate engineering student population at a large, Southwestern public university, and an exploratory factor analysis (EFA) was conducted on the responses. Lastly, evidence of reliability was obtained by computing the internal consistency of each resulting scale. The final instrument has seven scales with 67 items across 10 factors. The Cronbach alpha values for these scales range from 0.85 to 0.97. The full paper will provide complete details about the development and psychometric evaluation of the instrument, including evidence of and reliability. The instrument described in this paper will ultimately be used as part of a larger, National Science Foundation-funded project investigating the factors influencing online undergraduate engineering student persistence. It is currently being used in the context of this project to conduct a longitudinal study intended to understand the relationships between the experiences of online undergraduate engineering students in their courses and their intentions to persist in the course. We anticipate that the instrument will be of interest and use to other engineering education researchers who are also interested in studying the population of online students.more » « less

null (Ed.)Student research in STEM education is an important learning component for both undergraduate and graduate students. It is not sufficient for students to learn passively in lecture-based classrooms without engaging and immersing themselves in the educational process through real-world research learning. Experiential learning for STEM students can involve conducting research, alongside and through the guidance of their professors, early in a student’s undergraduate or graduate program. The authors consider such experiences to be the hallmark of a high-quality STEM education and something every student, undergraduate and graduate, should have during the course of their programs. The purpose of this case study is to document the faculty authors’ experiences in student-faculty research and provide guidance and recommendations for best practices based upon the authors’ experience, data, and literature findings. Moreover, the study presents the experience of the faculty authors’ international student researchers in STEM with focus on two student researchers, one undergraduate and one graduate, who are international STEM. The students served as co-authors on this project. Findings from this case study indicate that students were highly engaged in the research process and found these skills valuable preparation for further study and career. Moreover, the students expressed enthusiasm and engagement for the research process.more » « less

Providing hands-on learning experiences increases student understanding of theory and practices in STEM (science, technology, engineering, and mathematics) fields. The experience gives students motivation and allows them to focus their career path towards completing a degree in a STEM field. This paper provides initial observations on the learning impact of community college students and their instructors participating in the Support Center for Microsystems Education 2021 Undergraduate Research Experience. Twenty undergraduate community college students and their instructors participated in a week-long hands-on project-based course in a cleanroom environment. Both students and instructors showed an increase in the level of knowledge regarding microfabricating based on the collected survey results after completing the program. Survey results and observations of participating mentors are presented.more » « less
