Effect of short-term intensive design-based STEM learning on executive function: an fNIRS study of the left-behind children.

Design-based STEM learning is believed to be an effective cross-disciplinary strategy for promoting children's cognitive development. Yet, its impact on executive functions, particularly for disadvantaged children, still need to be explored. This study investigated the effects of short-term intensive design-based STEM learning on executive function among left-behind children. Sixty-one Grade 4 students from a school dedicated to the left-behind children in China were sampled and randomly assigned to an experimental group (10.70 ± 0.47 years old, n = 30) or a control group (10.77 ± 0.43 years old, n = 31). The experimental group underwent a two-week design-based STEM training program, while the control group participated in a 2-week STEM-related reading program. Both groups were assessed with the brain activation from 4 brain regions of interest using functional near-infrared spectroscopy (fNIRS) and behavioral measures during a Stroop task before and after the training. Analysis disclosed: (i) a significant within-group time effect in the experimental group, with posttest brain activation in Brodmann Area 10 and 46 being notably lower during neutral and word conditions; (ii) a significant between-group difference at posttest, with the experimental group showing considerably lower brain activation in Brodmann Area 10 and Brodmann Area 46 than the control group; and (iii) a significant task effect in brain activity among the three conditions of the Stroop task. These findings indicated that this STEM learning effectively enhanced executive function in left-behind children. The discrepancy between the non-significant differences in behavioral performance and the significant ones in brain activation implies a compensatory mechanism in brain activation. This study enriches current theories about the impact of Science, Technology, Engineering, and Mathematics (STEM) learning on children's executive function development, providing biological evidence and valuable insights for educational curriculum design and assessment.

Effects of double-dose algebra on college persistence and degree attainment.

In 2003, Chicago Public Schools introduced double-dose algebra, requiring two periods of math-one period of algebra and one of algebra support-for incoming ninth graders with eighth-grade math scores below the national median. Using a regression discontinuity design, earlier studies showed promising results from the program: For median-skill students, double-dose algebra improved algebra test scores, pass rates, high school graduation rates, and college enrollment. This study follows the same students 12 y later. Our findings show that, for median-skill students in the 2003 cohort, double-dose significantly increased semesters of college attended and college degree attainment. These results were not replicated for the 2004 cohort. Importantly, the impact of the policy on median-skill students depended largely on how classes were organized. In 2003, the impacts on college persistence and degree attainment were large in schools that strongly adhered to the cut-score-based course assignment, but without grouping median-skill students with lower-skill peers. Few schools implemented the policy in such a way in 2004.

A workshop to showcase the diversity of scientists to middle school students.

Identity matters in science, technology, engineering, mathematics, and medicine (STEMM) because it can affect an individual's long-term sense of belonging, which may in turn affect their persistence in STEMM. Early K-12 science classes often teach students about the foundational discoveries of the field, which have been predominately made, or at least published, by White men. This homogeneity can leave underrepresented individuals in STEMM feeling isolated, and underrepresented K-12 students may feel as though they cannot enter STEMM fields. This study aimed to examine these feelings of inclusivity in STEMM through an interactive workshop that asked middle schoolers to identify scientists from images of individuals with various racial and gender identities. We found that a plurality of students had a positive experience discussing diversity in science and recognizing underrepresented individuals as scientists.NEW & NOTEWORTHY We observed positive sentiments from middle school students following a workshop that showcased diversity in science. This workshop uniquely encourages students to recognize that physiologists and scientists today are much more diverse than textbooks typically demonstrate and can be adapted for middle schoolers, high schoolers, and college students.

An exploration of the relationship between active learning and student motivation in STEM: a mixed methods study.

Much of the research on science, technology, engineering, and mathematics (STEM) students' motivation measures the relationship between student motivation and academic outcomes, focusing on the student's mindset. Our mixed-methods research takes a different approach and considers the relationship between student motivation and instructional practices. Teaching practices and student motivation were analyzed simultaneously in undergraduate Biology classes using a self-determination theory-based survey to measure students' motivation during courses that were observed using the Classroom Observation Protocol for Undergraduate STEM (COPUS), and observation notes were collected to document instructor and student behaviors. Quantitative data were used to differentiate students' motivational levels, and qualitative data were collected to describe how instructors use specific teaching practices. The results provide a lens into how students' intrinsic motivation varies alongside the instructional practices and interactions in these classes. We found a correlation between higher levels of student motivation in interactive lectures and student-centered teaching profiles. This study highlights how the same practice can be implemented by multiple instructors with varying student motivation scores, pointing out the importance of fidelity to evidence-based instructional practice methods. The results of this study are discussed in the context of published empirical studies examining evidence-based instructional practices that are conceptually supportive of autonomy, competence, and relatedness. Active learning practices observed in this study correlated to positive learning outcomes are discussed and may serve as a guide for instructors interested in implementing specific active learning practices. Recommendations for instructors and departments that are interested in flexible methods to monitor progress toward active learning practices in biology and other STEM disciplines by combining the COPUS and self-determination survey results are presented.NEW & NOTEWORTHY This study uses a novel combination of instruments to describe students' intrinsic motivation in response to teaching practices. Findings demonstrate that active learning methods may support higher student motivation. Recommendations drawn from the study include using a variety of active learning methods, using evidence-based instructional methods with fidelity, and monitoring the students' affective response to those methods. Alignment of active learning practices to the components of self-determination may result in higher quality student motivation in science, technology, engineering, and mathematics (STEM) courses.

Loom: A Modular Open-Source Approach to Rapidly Produce Sensor, Actuator, Datalogger Systems.

In the face of rising population, erratic climate, resource depletion, and increased exposure to natural hazards, environmental monitoring is increasingly important. Satellite data form most of our observations of Earth. On-the-ground observations based on in situ sensor systems are crucial for these remote measurements to be dependable. Providing open-source options to rapidly prototype environmental datalogging systems allows quick advancement of research and monitoring programs. This paper introduces Loom, a development environment for low-power Arduino-programmable microcontrollers. Loom accommodates a range of integrated components including sensors, various datalogging formats, internet connectivity (including Wi-Fi and 4G Long Term Evolution (LTE)), radio telemetry, timing mechanisms, debugging information, and power conservation functions. Additionally, Loom includes unique applications for science, technology, engineering, and mathematics (STEM) education. By establishing modular, reconfigurable, and extensible functionality across components, Loom reduces development time for prototyping new systems. Bug fixes and optimizations achieved in one project benefit all projects that use Loom, enhancing efficiency. Although not a one-size-fits-all solution, this approach has empowered a small group of developers to support larger multidisciplinary teams designing diverse environmental sensing applications for water, soil, atmosphere, agriculture, environmental hazards, scientific monitoring, and education. This paper not only outlines the system design but also discusses alternative approaches explored and key decision points in Loom's development.

Increasing STEM Skills, Knowledge and Interest Among Diverse Students: Results from an Intensive Summer Research Program at the University of California, San Francisco.

This study evaluates the effectiveness of the UCSF Summer Student Research Program (SSRP) in enhancing research-related skills, academic outcomes, and post-baccalaureate aspirations of underrepresented minority (URM) and non-URM undergraduate students in biomedical sciences and STEM fields. The SSRP, spanning 9 weeks, provides immersive research experiences, structured mentorship, trainings, seminars, and STEM education. Pre- and post-program survey data from eight cohorts (N = 315) were analyzed using paired-sample t-tests, MANOVA, and content analysis. Results demonstrate significant gains in critical thinking skills, research abilities, science identity, applied science skills, and readiness for a research career. Notably, participants exhibited improvements in understanding the research process, scientific thinking, science writing, and problem-solving. URM and non-URM students experienced similar gains, highlighting the program's inclusivity. The SSRP also positively influenced students' postgraduate aspirations. Some participants expressed heightened interest in pursuing Master of Arts, Ph.D., and M.D. degrees, indicating increased clarity and motivation towards advanced education and research careers. Furthermore, 87% of participants expressed a high likelihood of engaging in future research endeavors, underscoring the program's sustained impact on research interest. This study underscores the transformative potential of a well-structured, intensive summer research program in significantly enhancing academic outcomes for URM and non-URM students alike. These findings align with the persistence framework, emphasizing the importance of early research experiences, active learning, and learning communities in fostering student success. The SSRP's effectiveness in improving research skills and post-baccalaureate aspirations suggests its potential in diversifying the STEM fields, biomedical sciences and health-related professions.

Familia, Comunidad y Maestros: How I Became a Latina Science Professor.

AbstractPeople of Mexican origin in the United States have long experienced discrimination in wages, housing, and schooling, which directly impacts their participation in the STEM (science, technology, engineering, and mathematics) workforce. Using interviews of Latina scientists and teachers, autoethnography, family and newspaper archives, and history and social science research, I reflect on key aspects of Mexican and Mexican American history that contribute to the challenges faced by Latinos in the US educational system today. Analysis of my own educational trajectory reveals the hidden part that teacher role models in my community and in my family played in my journey to becoming a scientist. Latina teachers and faculty, middle school science programs, and the provisioning of stipends for undergraduate researchers are emphasized as strategies for increasing student retention and success. The article concludes with several suggestions for how the ecology and evolutionary biology community can amplify the educational success of Latinos in STEM by supporting the training of Latino and other minoritized science, math, and computer science teachers.

Proposal for Monitoring Students' Self-Efficacy Using Neurophysiological Measures and Self-Report Scales.

The role of STEM-science, technology, engineering, mathematics-education is internationally recognized as critical to both the personal development of students and their future contribution to a country's economy as through this education they are equipped with the necessary twenty-first-century skills. As a result, there is a need to study the way in which such education affects students. In particular, the study of the self-efficacy factor is a contribution in this direction. Self-efficacy is a fundamental concept in the learning process as it contributes to shaping learning outcomes. Self-report scales are commonly used to measure self-efficacy; however, concerns in research circles have been raised regarding their limitations. On the other hand, there is a growing research interest in neurophysiological measures in the field of education, which seem to offer promising possibilities for understanding learning. Therefore, to better determine the impact of STEM education on students, a combination of self-report scales and neurophysiological measures is proposed to measure self-efficacy.

Innovative teaching knowledge stays with users.

Programs seeking to transform undergraduate science, technology, engineering, and mathematics courses often strive for participating faculty to share their knowledge of innovative teaching practices with other faculty in their home departments. Here, we provide interview, survey, and social network analyses revealing that faculty who use innovative teaching practices preferentially talk to each other, suggesting that greater steps are needed for information about innovative practices to reach faculty more broadly.

Gender disparity in STEM education: a survey research on girl participants in World Robot Olympiad.

Robotics competitions boosts the development of STEM education, but gender disparity in this field remains rarely addressed by researchers. This study focused on the World Robot Olympiad (WRO) and tried to explore the gender differences through investigation method. The research questions are as follows: RQ1, what is the tendency of girls' participation in WRO from 2015 to 2019 in terms of the four competition categories and three age groups? RQ2, what advantages and challenges do the all-girl teams have from the perspectives of parents, coaches and students? The results showed that among the 5956 participants in the 2015-2019 WRO finals, girls accounted for only 17.3%. The Open Category that emphasized creativity attracted relatively more girl participants. As age group moved up, the number of girl participants decreased. The qualitative results showed that the focuses of coaches, parents and students was not exactly the same. All-girl team have the advantages in their communication, presentation and collaboration skills but less good at robot building. The results indicated the importance of promoting girl's participation in robot competitions and STEM fields. Coaches, mentors and parents need to provide girls with more support and encouragement in learning STEM subjects, especially at the junior high school level. Organizers of related competitions should give girls more exposure and opportunities by adjusting the mechanism.

Designing Maker initiatives for educational inclusion.

The "Maker" movement is a cultural as well as educational phenomenon that has the potential to offer significant opportunities to students in conditions of social, economic and cultural disadvantage. The research reported in this paper, however, suggests that the simple provision of "Maker Spaces" for such activity is simplistic and not sufficient to realise this potential. The research involved a mixed methods study of a cohort of year 7 students (n = 26) in an Australian school located in a socio-economically disadvantaged outer-metropolitan region. The cohort undertook a range of Maker activities at a new "creativity centre" built at the school. Results indicate that the activities had positive impact on student attitudes towards science, technology, engineering and mathematics (STEM) overall, but that the impact was highly specific across attitudinal constructs. A strong ranging effect was also evident, suggesting that the impact of the experience was highly dependent on students' initial attitudes. Reflecting on these results, the paper also offers a reference framework that may help keep equity in mind when designing different kinds of Maker experience.

Development and validation of the STEM Teaching Self-efficacy Scale (STSS) for early childhood teachers.

The preparation of STEM (science, technology, engineering, and mathematics) teachers for early childhood education (ECE) has clearly become an important issue in recent years. Teacher efficacy can lead to changes in professional beliefs toward and teaching practices in STEM. In this study, we developed the STEM Teaching Self-efficacy Scale (STSS) and validated it in a sample of 225 pre-service and 193 in-service early childhood teachers in Zhejiang, China. Results indicated preliminary evidence of reliability and validity of the two factors of STSS: Pedagogy Self-efficacy and Content Self-efficacy. Items were constructed based on literature and selected through factor analysis to cover the scope of self-efficacy on the behaviors of STEM teaching and ensure the content and construct validity of the scale. Scores on the STSS subscales were positively correlated with early childhood teachers' working status, age, occupational commitment, and interest in ECE, showing evidence of its criterion validity. The STSS provides a professionally and psychologically meaningful tool for evaluating early childhood teachers' efficacy beliefs about teaching STEM, which would help obtain evidence for the optimal design of STEM teacher training programs.

Developing an Integrated STEM Classroom Observation Protocol Using the Productive Disciplinary Engagement Framework.

STEM education and research has gained popularity internationally over the last decade. However, there is a lack in specifications in existing K-12 STEM classroom observation protocols of how features of an integrated STEM experience/lesson would lead to desired outcomes and how those outcomes should be measured. To bridge this gap, we propose the development of a new integrated STEM classroom observation protocol (iSTEM protocol). This article describes the ongoing development work of the iSTEM protocol, which features two creative attempts. Firstly, the productive disciplinary engagement framework is adapted to design a classroom observation protocol that provides a coherent frame of design principles to be met to achieve desired 3-dimensional pedagogical outcomes. Secondly, interdisciplinarity of student engagement was interpreted in terms of the extent to which students take a systematic and disciplinary-based approach to make and justify decisions during STEM problem-solving. The iSTEM protocol comprises 15 items (4-point scale) rated holistically for the extents to which evidence was found in the observed lesson for (1) the 3-dimensional pedagogical outcomes of productive interdisciplinary engagement (five items) and (2) problematising, resources, authority, and accountability design principles (10 items). The accompanying iSTEM profile visually represents and communicates the strengths and inadequacies in design principles, thus providing explanations for extents of students' productive interdisciplinary engagement. The iSTEM protocol will contribute as a research tool for STEM education researchers and as a pedagogical guide for STEM classroom teachers to improve their design of STEM learning experiences.

Examining Science and Technology/Engineering Educators' Views of Teaching Biomedical Concepts Through Physical Computing.

Programming and automation continue to evolve rapidly and advance the capabilities of science, technology, engineering, and mathematics (STEM) fields. However, physical computing (the integration of programming and interactive physical devices) integrated within biomedical contexts remains an area of limited focus in secondary STEM education programs. As this is an emerging area, many educators may not be well prepared to teach physical computing concepts within authentic biomedical contexts. This shortcoming provided the rationale for this study, to examine if professional development (PD) had a noticeable influence on high school science and technology and engineering (T&E) teachers' (1) perceptions of teaching biomedical and computational thinking (CT) concepts and (2) plans to integrate physical computing within the context of authentic biomedical engineering challenges. The findings revealed a significant difference in the amount of biomedical and CT concepts that teachers planned to implement as a result of the PD. Using a modified version of the Science Teaching Efficacy Belief Instrument (STEBI-A) Riggs and Enochs in Science Education, 74(6), 625-637 (1990), analyses revealed significant gains in teachers' self-efficacy toward teaching both biomedical and CT concepts from the PD. Further analyses revealed that teachers reported increases in their perceived knowledge of biomedical and CT concepts and a significant increase in their intent to collaborate with a science or T&E educator outside of their content area. This study provides implications for researchers and educators to integrate more biomedical and physical computing instruction at the secondary education level.

Online collaborative learning and cognitive presence in mathematics and science education. Case study of university of Rwanda, college of education.

This study aims to investigate how online collaboration can support the learning of science, technology, engineering, and mathematics (STEM) in higher education. Empirical data were collected from 88 postgraduate students studying at the African Centre of Excellence for Innovative Teaching Learning Mathematics and Science (ACEITLMS) using online oral interviews and two five-point Likert scale questionnaires. Interviews were analysed through content analysis while data from the questionnaire were scanned through the Statistical Package for Social Scientists (SPSS) to compute descriptive statistics and Spearman rho correlation coefficient. The findings indicate that online collaborative learning through small group discussions prompt knowledge co-construction, and higher-order thinking skills in STEM subjects. Moreover, the findings demonstrate how several electronic multimedia tools (PhET simulations, animations, YouTube videos) can increase student retention and engagement in learning STEM. Though the students reported that they experienced challenges such as poor internet connection, lack of laboratory work, electricity shortage, and limited ICT skills, they managed to complete STEM learning activities by using free virtual laboratories, portable tethering hotspots from their smartphones, and smartphones where power was a problem and learnt the navigation of ICT tools from their peers. The study found moderate positive Spearman rho correlation coefficient, r s = 0.69 , P < 0.01 which explains that 69% of the total variance in the students' successful performance is explained by the two variables, i.e., social and cognitive presence. The study recommends more training for course instructors and students. Efforts should be put in place to focus on ICT manipulation and curating interactive content. The researchers acclaim the expansion of internet coverage in University of Rwanda campuses. This action will enhance online and blended learning. Moreover, the study recommends the integration of ICT and the use of multimedia tools such as Bio-interactive and Physics Education Technology (PhET) interactive simulations in STEM subjects as supplementary resources. These tools support cognitive and affective domains in the teaching and learning process. Furthermore, universities can reduce the problem of expensive and inadequate laboratory equipment by adopting the use of virtual laboratories, especially for online STEM lessons.

Online technological STEM education project management.

With a strong demand for online education and project management in deeper scope and larger scale to better fit COVID-19 pandemic situation, exploring new knowledge of online education to make it more effective became vital with the new challenges of STEM education. To resolve the above problem, this paper focuses on various aspects of online STEM education project management where the Enhanced Noyce Explorers, Scholars, Teachers (E-NEST) three-tiered structure was implemented during the COVID-19 period. Two City University of New York (CUNY) institutions, New York City College of Technology (City Tech) and Borough of Manhattan Community College (BMCC) used the three-tiered structure referred to as Explorer, Scholar and Teacher which incorporated advancements in teaching internships, professional development workshops and mentorships remotely. Built upon the theories of engagement, capacity and continuity (ECC) and team-based learning (TBL), this remote learning model and infrastructure had a positive impact on STEM education and project management. The technological tools utilized included Zoom, Google Meet, Microsoft teams, Blackboard Collaborate Ultra, Skype and SurveyMonkey. The results from qualitative and quantitative data including project evaluation, online surveys and focus group interviews demonstrate that the modified remote learning and management tools were effective. This indicated that the E-NEST model greatly supported student success and faculty in online learning and project management meetings. The E-NEST STEM education project was compared to two other project management models along with the previous NEST curriculum. Faculty emphasized practicing project management proactively and utilized best practices of classroom and time management consistent with Project Management Body of Knowledge (PMBOK) and Project Cycle Management (PCM) guidelines. The comparisons attest that the E-NEST project developed excellent and innovative online platforms for student learning with project management and ECC and TBL applications. Hereafter, this research can be used to constructively develop more online STEM education learning models and platforms and integrate new practice and technology globally. These ideas can contribute to future research that could be applied internationally to STEM education projects in K-12 and higher education institutions.

Navigating the "COVID hangover" in physiology courses.

Undergraduate educators and students must navigate lingering aftereffects of the COVID pandemic on education in the 2021-2022 academic year even as COVID continues to impact delivery of undergraduate science education. This article describes ongoing difficulties for undergraduate science, technology, engineering, and mathematics (STEM) students and educators and suggests strategies and easy-to-use resources that may help educators navigate the "COVID hangover" and ongoing COVID-related disruptions.

Learning design in science education: perspectives from designing a graduate-level course in evidence-based teaching of science.

Graduate students intending to pursue an academic career in the sciences have much to gain by learning to teach science but often have limited training opportunities. In response to this need, we designed a one-semester course, Learning Design in Science Education (LDSE), in which students receive formal training in pedagogical theory with role model demonstration of current best practices in active learning. Building from previous descriptions of similar courses, we added a practical experience for the students to utilize their new skills to design and teach a mini science course at the end of the semester. Additionally, students developed a teaching portfolio, complete with a personal teaching statement, syllabus, course materials, and evaluations from peers and faculty. Overall, the course was well received by the students and there are early indications that students benefited from their participation in the course. In this manuscript, we present the design and outcomes of the course, faculty and student perceptions, and thoughts on improvements for future semesters and its potential for use by others.NEW & NOTEWORTHY The need for graduate students and other trainees to learn effective methods for teaching science is greater than ever. In this manuscript, we offer a model course for the training of graduate students in learning theory, curriculum design, and technology use in a biomedical sciences environment.

Robotics Education in STEM Units: Breaking Down Barriers in Rural Multigrade Schools.

We report a novel proposal for reducing the digital divide in rural multigrade schools, incorporating knowledge of robotics with a STEM approach to simultaneously promote curricular learning in mathematics and science in several school grades. We used an exploratory qualitative methodology to implement the proposal with 12 multigrade rural students. We explored the contribution of the approaches to the promotion of curricular learning in mathematics and science and the perceptions of using robotics to learn mathematics and science. As data collection techniques, we conducted focus groups and semi-structured interviews with the participants and analyzed their responses thematically. We concluded that the proposal could contribute to meeting the challenges of multigrade teaching. Our findings suggest that the proposal would simultaneously promote the development of curricular learning in mathematics and science in several school grades, offering an alternative for addressing various topics with different degrees of depth.

Translational Applications of Wearable Sensors in Education: Implementation and Efficacy.

BACKGROUND: Adding new approaches to teaching curriculums can be both expensive and complex to learn. The aim of this research was to gain insight into students' literacy and confidence in learning sports science with new wearable technologies, specifically a novel program known as STEMfit. METHODS: A three-phase design was carried out, with 36 students participating and exposed to wearable devices and associated software. This was to determine whether the technology hardware (phase one) and associated software (phase two) were used in a positive way that demonstrated user confidence. RESULTS: Hardware included choosing a scalable wearable device that worked in conjunction with familiar and readily available software (Microsoft Excel) that extracted data through VBA coding. This allowed for students to experience and provide survey feedback on the usability and confidence gained when interacting with the STEMfit program. Outcomes indicated strong acceptance of the program, with high levels of motivation, resulting in a positive uptake of wearable technology as a teaching tool by students. The initial finding of this study offers an opportunity to further test the STEMfit program on other student cohorts as well as testing the scalability of the system into other year groups at the university level.
