As widespread as Science, Technology, Engineering, and Math (STEM) initiatives and reforms are today in education, a rudimentary problem with these endeavors is being overlooked. In general, education programs and school districts are failing to ensure that elementary teachers who provide children's early academic experiences have the appropriate knowledge of and proclivity toward STEM subjects. This issue is further compounded by the focus centered on mathematics due to accountability requirements leaving very little emphasis on science, and most often, the exclusion of technology and engineering instruction from the curriculum (Blank, 2012; Cunningham, 2009; Lederman and Lederman, 2013; Lewis, Harshbarger, and Dema, 2014; Walker, 2014). At the elementary level, the lack of science instruction and professional development generates a weakness for both pre- and in-service teachers and prompts elevated concerns about teaching science (Goodrum, Cousins, and Kinnear, 1992; Anderson, 2002). Research (Lewis, 1999/2006; Wells, 2014) suggests that one way to address this weakness is through the technological/engineering designed-based approach within the context of integrative STEM education. The purpose of the study was to gain an understanding of change in science instructional content and practice through professional development that educates elementary teachers to implement Technological/Engineering Design Based Learning (T/E DBL) as part of teaching science. The research design was a multiple case study which adhered to a concurrent mixed method approach (Teddlie, and Tashakkori, 2006; Yin, 2003),with four participants who were recruited because of their availability and their grade level teaching assignment that correlated to an analysis of the 2013 science state accountability test, Standards of Learning (Pyle, 2015). Data collected from surveys were analyzed using descriptive and inferential statistics. These data were corroborated with a sweep instrument and assessment rubric analyses, and interview responses to validate the results. Findings from this study revealed that professional development model used in this study was clearly effective in getting elementary teachers to implement T/E DBL. The participants were better able to integrate T/E DBL when planning and designing instructional units and had an improved understanding of the science concepts they were teaching. / Ed. D.

Science, Technology, Engineering, and Mathematics (STEM) education is spurred by an economic and social need for cross-discipline understanding of complex, worldwide problems, made through intentional connections between two or more STEM subject areas. In order for educators to articulate these connections, research suggests they must have a firm understanding of the individual disciplines through both content and pedagogical approaches. In 2007, as a leader in non-formal STEM education, 4-H made a specific commitment to improve STEM literacy in America's youth by forming the 4-H Science mission mandate, therefore increasing its STEM programming. This qualitative study examined how 4-H educators come to understand STEM and engineering concepts and utilizations, and whether their backgrounds influence their verbalization or expectations of engineering. Narrative themes emerged that help determine how engineering is currently and can continue to be more clearly and consistently articulated and connected within 4-H programming. Themes included 1) a lack of direct connection or understanding of engineering characteristics to 4-H programs, 2) familiarity with and ability to apply engineering characteristics to the Do Reflect Apply model, and 3) the importance of volunteers as STEM and engineering educators within 4-H programming. Strategies for professional development emphasizing engineering understandings, learning outcomes, and broad applications were discovered. Professional development should consider the effects of engineering and STEM self-efficacy, as well as professional identity development. Additionally, it utilize approaches such as the Do Reflect Apply model, and reflect on the learning objectives 4-H educators strive to achieve during STEM programming in conjunction with life-skills. / Master of Science in Life Sciences / In 2007, 4-H made a specific commitment to improve Science, Technology, Engineering, and Mathematics (STEM) literacy in America’s youth by forming the 4-H Science mission mandate. However, research suggests in order for educators to successfully implement STEM programming, they need to understand the content and best teaching practices, which presents a unique obstacle for 4-H educators as many lack formal education in both. By conducting interviews with current 4-H educators in Virginia, this research begins to highlight the importance behind STEM understanding and STEM teaching practices – particularly as they pertain to engineering projects. These interview and data analysis process uncovered common themes including connections between engineering and current 4-H educational approaches, as well as the existing barriers between volunteers as STEM educators and successful programming. In order to improve STEM education within 4-H, professional development strategies focusing on engineering characteristics, outcomes aligning with 4-H goals, and applications to real-world problems should be implemented.

The United States of America needs STEM trained workers, STEM faculty and STEM professionals to improve its technical and professional workforce in order to maintain leadership in a global economy. However, American students are not opting to remain in a STEM course of study, and this is especially so for women and minorities. Of the students who pursue post-secondary education, the majority of movement away from STEM majors occurs in the first two years. Thus, educators are concerned with investigating factors that may influence students' persistence and success when in a STEM track of learning. To that end, this quasi-experimental mixed-method study was concerned with investigating the effects of participation in the design process on student self-efficacy and content knowledge gains in an undergraduate anatomy and physiology laboratory. Over fifty students participated in a design task that paralleled the topic being studied in a given semester and were given efficacy surveys along with lab practicums. Qualitative efficacy data, quantitative efficacy data and quantitative practicum results were analyzed and triangulated to produce a meta-inference as to the effect of participation in the design project had on student learning. Preliminary results indicate that the design process makes statistically significant impacts on both self-efficacy and content knowledge in the given context. The author follows with a discussion of the impact of design-based learning in the undergraduate biology classroom and implications for further research are considered. / Ph. D.

<p dir="ltr">In recent years, employers and business leaders have increasingly discussed the topic of college graduate job readiness. A recent survey found that approximately 60% of employers expressed concerns about college graduates' preparedness for today's workforce and cited issues with work ethic, professionalism, communication skills, and technological skills, particularly among Generation Z graduates (Behbahani, 2023; Daniels, 2023; Heubeck, 2023; Intelligent, 2023; Kelly, 2024). With the rise of generative AI technologies, hiring practices are shifting towards skill-based hiring rather than degree-based hiring. As a result, many college graduates are left wondering whether they are adequately prepared for the constantly evolving workforce (Cengage Group, 2023; Flaherty, 2024; Mowreader, 2023; Nietzel, 2023). With workplace and educational technology constantly changing, higher education institutions and educators should consider providing more support and guidance to better prepare students for working with technology and in fast-paced environments. That being said, innovative approaches should be considered for reforming existing college degree programs and developing new programs. One such approach that can be used for continuous improvement, program assessment, and as a pedagogical intervention in Science, Technology, Engineering, and Mathematics (STEM) classrooms is the participatory action research method, photovoice.</p>

Preparing students to be life-long learners that are career and college ready is a goal of agricultural education. Changing expectations of education have pointed to agriculture educators as potential leaders in the STEM education movement. Literature related to STEM education in agricultural education is lacking in guidance for teachers, administrators, and curriculum developers in integrating academic content related to STEM content areas. A review of STEM education literature coupled with the framework of quantitative reasoning, lead to a conceptualization of a framework for integrative agricultural education. This framework was implemented through a case study to investigate collaborative efforts in curriculum development in agricultural education with a specific focus on integrating mathematics to develop students' quantitative reasoning skills. Teacher characteristics were identified that seemed to support the implementation of integrative agricultural education practices. Teaching and planning strategies were also identified in the case study. Recommendations suggest support of collaboration between agriculture and mathematics teachers would best support curriculum design and aid in the quality of instruction that follows. / Ph. D. / Agricultural education teachers work to prepare students to be life-long learners that are career and college ready. STEM education has become vogue in education. As expectations change about what students should learn and how they learn it, agriculture educators have potential to be leaders in the STEM movement. STEM education in agricultural education is lacking in guidance for teachers, administrators, and curriculum developers in integrating academic content related to STEM content areas. This dissertation presents a conceptualization of a framework for integrative agricultural education that combines elements characteristic of STEM education coupled with the concept of quantitative reasoning. The framework was used to research collaborative efforts in curriculum development in agricultural education with a specific focus on integrating mathematics to develop students’ quantitative reasoning skills. Results provide teacher characteristics that seemed to support implementation of integrative agricultural education practices. Teaching and planning strategies were also identified that lead to recommendations suggesting support of collaboration between agriculture and mathematics teachers would best support curriculum design and aid in the quality of instruction that follows.

<p dir="ltr">This thesis investigates the impact of Immersive Virtual Reality (IVR) on student engagement in undergraduate STEM education. The study addresses the growing demand for innovative learning technologies, especially in response to the shift to remote education during the COVID-19 pandemic. IVR offers unique advantages by immersing students in fully interactive environments that reduce distractions and enhance experiential learning. The research explores how IVR compares to traditional methods in fostering student engagement and participation, particularly in STEM disciplines.</p><p dir="ltr">A comprehensive literature review reveals gaps in understanding how IVR impacts student motivation, agency, presence, and immersion. The Cognitive Affective Model of Immersive Learning (CAMIL) serves as the theoretical framework, suggesting that immersive environments can improve educational outcomes by enhancing learners’ control (agency) and emotional engagement (presence).</p><p dir="ltr">The study employed a cross-over experimental design involving undergraduate students who participated in both IVR and traditional PowerPoint (PPT) lessons. Data was collected using surveys based on validated scales for motivation, presence, agency, and immersion. The study also incorporated a Retrospective Post-Then-Pre (RPT) assessment to measure shifts in student perceptions of their learning experiences. The use of this design allowed for an in-depth comparison of the effects of IVR versus traditional instruction.</p><p dir="ltr">Results indicated that IVR significantly improved students’ sense of immersion, though no significant differences were observed in terms of motivation or presence compared to traditional methods. Interestingly, students reported higher levels of agency during PPT lessons, suggesting that the structured nature of traditional instruction made them feel more in control. These findings highlight the nuanced ways different implementations of IVR impact key dimensions of student engagement.</p><p dir="ltr">The discussion reflects on the broader implications of these results, particularly the technical limitations encountered with the Meta Quest 1 headsets, which may have hindered the full potential of the IVR experience. While IVR offers promising opportunities for enhancing engagement, technical challenges and students’ preference for familiar learning environments suggest a need for a balanced integration of immersive and traditional methods.</p><p dir="ltr">The conclusion proposes that hybrid learning models, which combine IVR's interactivity with traditional formats' structure, may offer the best path forward for integrating immersive technologies into STEM education. Practical recommendations for educators and policymakers are presented, emphasizing the importance of access to up-to-date equipment and training to maximize the benefits of IVR in academic settings.</p>

The purpose of this study was to determine if students with special needs participating in an inclusive classroom can learn the skills related to a STEM career as compared to the general student population. The study involved seventh grade students from two rural middle schools in north central Texas and was framed through a constructivist lens using a quasi-experimental design with a convenience sample. The Solenoid Invention Kit Assessment and the STEM Semantics Survey used in this study were used from a previously large existing dataset from a grant funded by the National Science Foundation for Innovative Technology Experiences for Students and Teachers. Findings suggested that there were no significant differences between the general student population and students with special needs. However, STEM coursework in an inclusive classroom may impact students' decision to pursue STEM careers.

Circumscription and Compromise theory suggests self-concept and sex stereotype explain occupational preferences, including preferences for science, technology, engineering and mathematics (STEM). Support exists for sex differences between males and females in both science degrees and science careers. The main thrust of observed sex differences in science lies in the development of occupational interest, as it has been suggested females are encouraged away from science due to stereotypes and social pressure. The present study evaluates high school juniors and seniors (n = 295) to explore their preference for science as indicated by science motivation, attitude, academic experience, and interest. Latent Profile Analysis was used to model profiles of preferences for science with a person-centered approach. Then, the impact of self-concept variables was explored and four profiles of science interest were identified. Sex differences were identified based on science interest, but were not always in favor of males. Covariate analysis indicates vocabulary ability and personality as significantly different for students in the high science interest profile. Implications of these results and future research directions are discussed.

<p>This qualitative study was conducted to understand the instructional strategies used by high school integrated STEM (iSTEM) teachers to apply real-world problem solving in their classrooms in the state of Indiana. The problem addressed by this study was the need to understand the instructional strategies employed by iSTEM teachers in their classrooms. Using a basic qualitative approach, data was collected through teacher interviews, classroom observations, and documents. The thematic analysis revealed several themes: (a) there is no single instructional strategy, but teachers adapt their strategies to the context, (b) the importance of preparation using various sources and building on student’s prior knowledge, (c) a focus on asking "why" questions as a priority, (d) the necessity of making group work tangible, (e) the use of modeling as a common strategy, including data collection and analysis, sketching and documentation, (f) the promotion of student independence by being aware and performing tasks independently, (g) the integration of real-world issues to relate learning to student lives, and (h) the challenges posed by time and diversity of student abilities. These findings suggest that iSTEM teachers should be flexible in their approach and emphasize preparation, questioning, modeling, group work, and real-world connections to improve student learning in an integrated STEM approach. The findings contribute to the existing literature on iSTEM teaching and have implications for iSTEM teachers, school administrators, and policymakers. The findings of this study can inform professional development programs for iSTEM teachers and can help school administrators design collaborative and problem-solving learning environments. Lastly, policymakers can use the findings to develop policies that promote the integration of real-world problem-solving into STEM education, thereby contributing to the development of a workforce that is prepared to meet the challenges of the 21st century.</p>

The Federal Government has called for an overhaul of STEM education, saying that we as a nation must increase "opportunities for young Americans to gain strong STEM skills" (Office of Science and Technology Policy, 2013, p.1). Economically, these skills expand beyond those that make good doctors, professors, and engineers; there is a world of jobs going unfilled because our students are graduating without the skills or knowledge that such opportunities exist. To increase the future STEM workforce, we first need to increase student awareness of a variety of STEM careers early on (Tai et al., 2006). Career decisions are being made by students as early as middle school (Tai et al., 2006); and very little if any STEM career exploration is occurring before high school. This lack of early exposure to STEM career options means that students are likely making decisions about career choices without accurate information; choosing a path before knowing about all the options. This research is broken into two manuscripts; the first of which examined the impacts of design-based learning and scientific inquiry curriculum treatments with embedded career content on the career interest of fifth-grade students as compared to traditional classroom methods. It found that there is an upward trend in career interest with the use of these curriculum treatments, but it is not a significant change, likely due to the short time period of the unit and/or small n. The second manuscript examined the effect of a design-based learning curriculum treatment implementation for a single unit on Radford City Schools fifth-grade students' STEM attitudes and interest in STEM careers through a pre/post design. The study showed statistically significant growth in overall STEM attitudes and within the science subtest specifically. Career interest in the general field of science showed a significant increase, while a change of interest in specific career areas was not statistically significant. Collectively, this research serves as a foundation for the effectiveness of having career awareness and career exposure opportunities built into active learning instruction, which does not occur currently. Built on secondary principles, but at a level appropriate for elementary students, using active learning opportunities with embedded career connections has the potential to be an effective solution to students' premature exclusion of STEM-related study and work options identified in the literature. Through preliminary exposure to this unique combination at the elementary level, a stronger foundation can be built for both ability and interest in STEM. / Ph.
