The purpose of this explanatory sequential mixed-methods study is to identify and describe the readiness of female Saudi mathematics teachers in the areas of subject matter knowledge and pedagogical content knowledge to integrate STEM disciplines. The study also examines mathematics teachers’ attitudes and obstacles in implementing STEM education. The sample consisted of 98 female mathematics teachers for the quantitative phase and 6 for the qualitative phase in Jeddah, Saudi Arabia. The findings revealed that Saudi female middle school mathematics teachers appeared to have extensive pedagogical knowledge and an average level of subject matter knowledge but they needed systematic support, such as training courses or professional development programs, to be able to implement integrated STEM education in their classes. Most of the participants also showed a positive attitude toward integrated STEM education and its implementation. The qualitative findings confirmed and explained the quantitative findings. Additionally, participants believed that teachers’ knowledge, preparation, motivation, and professional development in integrated STEM education as well as school setting were the most important obstacles that challenged the implementation of integrated STEM education. Based on the results, I recommend an integrated STEM education degree to prepare future STEM teachers and start an awareness campaign to educate people about STEM literacy and its importance for the country’s future.

To prepare students for the complex, multidisciplinary problems they will face outside of the classroom, current reform initiatives advocate for the integration of content and practices from science, technology, engineering, and mathematics (STEM) in the science classroom. One approach, integrated STEM, uses the engineering design process as a vehicle for learning. However, these lessons can be challenging for students, so it is essential that science educators employ various teaching practices to scaffold student learning. One way to achieve this is through the use of written and oral discourse that promotes meaning-making. The studies in this dissertation utilize Legitimation Code Theory as an analytical framework to create semantic profiles of an integrated STEM unit and middle school teachers’ implementation of integrated STEM lessons. Specifically, we analyze the semantic gravity, or the extent to which meaning is rooted within the context it is acquired in, to map and identify semantic patterns that may promote or constrain meaning-making. The results of these studies indicate that Legitimation Code Theory can be a useful tool for developing and examining integrated STEM curricular materials, evaluating teacher discourse during the implementation of integrated STEM lessons, ascertaining how teachers are integrating multiple disciplinary discourses, and identifying areas where teachers may benefit from additional support as they learn to implement integrated STEM. Keywords: integrated STEM, legitimation code theory, discourse.

Integrated STEM education and Universal Design for Learning (UDL) have been often theorized as compatible. However, there has been little research done to understand how UDL is used in real-world integrated STEM classrooms. Our study aimed to understand how current practicing educators in integrated STEM classrooms combine these teaching methodologies. This was done through a combination of interviews and document analysis of lesson plans, and supplementary information. To evaluate what elements of UDL were used in the documents, researchers developed a UDL codebook based off of the 31 checkpoints in the Center for Applied Special Technology (CAST) UDL guidelines. The goal of the study was to understand how the adoption of UDL could spread across all integrated STEM educators. Therefore, our study viewed the use of UDL in an integrated STEM classroom as an 'innovation' and analyzed our results through Diffusion of Innovation theory. Specifically looking to providing understanding to the 'innovation' through Rogers 5 Attributes of innovations. The study found that all except two UDL checkpoints were proved to be compatible within integrated STEM classrooms, and were categories developed to explain how the participant achieved these checkpoints. The findings also show that not all UDL checkpoints occur at the same frequency. Through Diffusion of Innovation theory, our study showed that Integrated STEM educators believe that UDL is automatically adopted by educators using Integrated STEM teaching methodologies. They expressed problems associated with implementing some UDL checkpoints, and providing overall themes of complexity when implement UDL in an Integrated STEM classroom. / Master of Science in Life Sciences / Integrated STEM education and Universal Design for Learning (UDL) are two teaching methodologies that have been often theorized to be compatible.

<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>

<p>For more than five decades, education scholars and activists have argued for a culturally relevant and nurturing education that reflects students' diverse experiences in K-12 classrooms. Yet, with the most recent national reform on science standards, the call to engage all learners pushed for advancing STEM in the United States, and many science education scholars have problematized such rhetoric. Unfortunately, the inclusionary blanket term like “engaging all learners” and the efforts that lead behind it do not consider the sociocultural realities that young children bring into the classrooms and the negotiation in learning school science. In this three-paper dissertation, I explore how middle school science teachers recognize the sociocultural realities students come with and cultivate a culturally nurturing education in response to the increase of racial, economic, and linguistic diversity within their integrated STEM classrooms. In particular, the aim of this dissertation to understand how middle school science teachers align school science, specifically in teaching integrated science and engineering, to the sociocultural realities of students by centering on the sensemaking of teacher’s lived experience and experiential knowledge. The first study draws on a narrative inquiry case study approach to understand how a middle school science teacher cultivated a culturally sustaining STEM classroom. The research question that guided this study was: How does Mrs. Johnson make meaning of her experiences in making science and engineering learning more culturally relevant and sustaining for her diverse middle school students? Findings from this study illuminates a complex narrative such as the intentionality of making multiple epistemologies explicit in learning science and engineering and the required racial reflexive work for cultivating a culturally sustaining and student-focused STEM classrooms. The findings also highlight challenges Mrs. Johnson faced as she integrates students’ lived experiences and alternative ways of knowing and doing into science and STEM teaching. The second study uses a single-case study approach to understand specific teaching practices that truncated the cultivation of a culturally sustaining education by exploring the opportunities that allowed internalized and interpersonal oppression to perpetuate with the same teacher, Mrs. Johnson. The research questions that guided this study are as follow: In what ways does teaching the GMO and Loon Nesting Platform STEM units foreground individual and interpersonal oppression to manifest? What teaching practices allow these moments of oppression to be pervasive? Findings from this study suggest that oppression becomes pervasive when teaching integrated science and engineering without considering how STEM learning could be irrelevant to students’ lived experiences and the role of power in teaching science. Based on these findings, I developed a year-long virtual professional development program that emphasized teaching integrated science and engineering with a focus on culturally nurturing and asset-based pedagogies. The final study draws on teachers’ funds of knowledge and identity to explore the sensemaking of a rural science teacher as he participates in the professional development program and how the sensemaking of his lived experiences informed his use of asset-based pedagogies. The research question that guided this study was: How do Mr. Jordan’s funds of knowledge and identity inform their use of asset-based pedagogies in reform-based, rural science classrooms? Findings from this study highlights Mr. Jordan’ funds of knowledge and identity informing his use of culturally responsive and relevant pedagogies. Implications of the third study proposes generational cultural wealth as a theoretical framework as one way teachers can begin aligning school science to students’ sociocultural realities. The final chapter of this dissertation presents a synthesis across the three studies and a summary of the implications for teaching.  </p>

<p>  </p> <p>Radian angle measure is central to learning trigonometry, with researchers providing evidence that a coherent understanding of radian contributes to a coherent understanding of trigonometric and inverse trigonometric functions. However, there are few opportunities for students to engage with curricular situations that involve radian angle measure. The purpose of this dissertation is to explore and provide insights into preservice mathematics teachers’ (PMTs’) conceptions of radian angle measure using three curricular situations. The first chapter reviews the relevant literature, which reported that PMTs’ conceptions of radian angle measure involve angles measured in terms of π, in relation to degrees, and in relation to the unit circle. In chapter two, I explored PMTs’ conceptions of radian angle measure using textbook representations. Seven PMTs participated in a think-aloud semi-structured interviews, where they defined radian angle measure from six textbook diagrams of radian, including a diagram of the unit circle. In chapter three, building on literature that reported that PMTs’ conceptions of radian angle measure involve relating radian to degrees, I explored how PMTs conceptualize this relationship. Five PMTs participated in semi-structured interviews, where they described radian angle measure given the angle measure in degrees. In chapter four, I explored the PMTs’ conceptions of radian angle measure given a novel context. Four PMTs participated in semi-structured virtual interviews, where they engaged with a digital activity that involves radian angle measure in the context of light reflection. Some of the dissertation’s findings align with previous research, where PMTs’ conceptualized radian angle measure in relation to the unit circle. However, this dissertation provides empirical evidence of why the PMTs refer to the unit circle. The PMTs acknowledged knowing the unit circle from memorization, but also explained that the purpose for using the unit circle is efficiency. At the same time, the PMTs acknowledged limitations in the unit circle and in their conceptions of it. Overall findings from the dissertation demonstrate the complexity of PMTs’ conceptions of radian angle measure. The PMTs’ conceptions were reported as concept definitions, ways of thinking, and spatial ways of thinking. The PMTs demonstrated flexibility with reasoning about radian angle measure using foundational conceptions in learning higher mathematics topics (e.g., proportional reasoning concepts, spatial ways of thinking). By positioning the PMTs as knowers and thinkers with valuable insights to provide, I was able to uncover and report a collection of conceptions that were demonstrated by PMTs when a curricular situation involved radian angle measure. The findings from this dissertation extend existing research that explored conceptions of angle measure and radian angle measure by reporting PMTs’ conceptions of radian angle measure given three different curricular situations. While there is still much that needs to be investigated about complexities in PMTs’ conceptions of radian angle measure, this dissertation represents one step toward providing insights about those complexities. </p>

<p>The Next Generation Science Standards (NGSS Lead States, 2013) promote a new vision of K-12 science education that emphasizes the importance of integrating engineering practices into science education. Recent engineering studies have highlighted design approaches that focus on designers’ empathy, such as human-centered design (Hess & Fila, 2016a; Kouprie & Visser, 2009; Walther et al., 2017). Empathic engineering design approaches can help students understand how engineers understand various users’ contexts and develop effective design solutions. Furthermore, empathy is a key element in cross-cultural education (Gay, 2002; Webb et al., 2012) because it can help teachers create positive interactions with diverse students (Arghode et al., 2013; Warren, 2014). Empathy is an important attribute highlighted in both engineering and cross-cultural education. Therefore, it is necessary for teachers to comprehend and integrate the principles of Human-Centered Design (HCD) approaches to provide more authentic and holistic engineering education. </p> <p>This study explored elementary preservice teachers’ competence in planning and implementing an empathic engineering design lesson plan in cross-cultural STEM education by applying a module. The module consisted of a researcher-developed elementary science methods unit on designing empathic integrated STEM instruction. Using a convergent mixed methods design (Creswell & Clark, 2018) and 16 participants, this study investigated preservice teachers’ understanding of empathic integrated STEM instruction before and after the module. This study utilized the Interpersonal Reactivity Index (Davis, 1983) to examine preservice teachers’ levels of empathy and the Teaching Engineering Self-Efficacy Scale (Yoon et al., 2014) to measure their self-efficacy. For qualitative data, reflection papers, empathic design lesson plans, and interview transcripts were collected. Thematic analysis (Braun & Clark, 2006) was employed to identify patterns and relationships within the data.</p> <p>The analysis of a paired samples t-test and a related-samples Wilcoxon signed-rank test showed a significant difference between the means of preservice teachers’ self-efficacy scores before and after the module. However, there was no significant difference in the means of their empathy scores. According to qualitative data analysis, preservice teachers understood the role of empathy in both engineering and cross-cultural education. The module enhanced preservice teachers’ pedagogical strategies regarding empathic techniques and culturally and socially responsive pedagogies. Preservice teachers also discovered the benefits of empathic integrated STEM instruction including broadening one’s perspectives, understanding the value of inclusive designs, and enhancing students’ 21st century skills. After experiencing the module, they felt confident in integrating empathic integrated STEM instruction and recognizing potential challenges of implementation. The study findings show that empathic integrated STEM instruction can be a way to support preservice teachers’ understanding of engineering pedagogical strategies, culturally responsive pedagogy, and the features of integrated STEM instruction. </p>

<p>  </p> <p>Food system STEM projects have the capacity to motivate high school students in urban schools. This study explored food as a context to engage students because everyone interacts with food on a daily basis and has had cultural experiences related to food. An integrated STEM approach in combination with a systems thinking approach challenged students to make transdisciplinary connections, view problems from different perspectives, analyze complex relationships, and develop 21st-century and career skills (Hilimire et al., 2014; Nanayakkara et al., 2017). The purpose of this study was to describe and explain the relevance students perceive in Ag+STEM content by measuring high school students' self-efficacy, intrinsic value, attainment value, cost value, and utility value after participating in a food system STEM project. The study was informed by Eccles and Wigfield’s (2020) Situated Expectancy Value Theory. The convenience sample of this study was comprised of high school students from metropolitan area schools. High school students completed a food system STEM project with a food system context. Quantitative data was collected using the developed Food System Motivation questionnaire. Data were collected through a retrospective pre-test and a post-test. Descriptive statistics were used to analyze the data including means and standard deviations. Relationships were explored by calculating correlations.</p> <p>There were four conclusions from this study. First, high school students were somewhat interested, felt it was important to do well, and agreed there were costs regarding participation in the food system STEM project. Second, high school students reported higher personal and local utility value motivation after completing the food system STEM project. Third, high school students were somewhat self-efficacious in completing the project tasks and completing the project tasks informed by their cultural identity and experiences. Fourth, intrinsic value and attainment value motivation (independent variables) were related to personal and local utility value motivation and project and cultural self-efficacy motivation (dependent variables). Implications for practice and recommendations for future research were discussed.</p>
