The objective of this thesis is to propose two novel interval observer designs for different classes of linear and hybrid systems with nonlinear observations. The first part of the thesis presents a novel interval observer design for uncertain locally Lipschitz continuous-time (CT) and discrete-time (DT) systems with noisy nonlinear observations. The observer is constructed using mixed-monotone decompositions, which ensures correctness and positivity without additional constraints/assumptions. The proposed design also involves additional degrees of freedom that may improve the performance of the observer design. The proposed observer is input-to-state stable (ISS) and minimizes the L1-gain of the observer error system with respect to the uncertainties. The observer gains are computed using mixed-integer (linear) programs. The second part of the thesis addresses the problem of designing a novel asymptotically stable interval estimator design for hybrid systems with nonlinear dynamics and observations under the assumption of known jump times. The proposed architecture leverages mixed-monotone decompositions to construct a hybrid interval observer that is guaranteed to frame the true states. Moreover, using common Lyapunov analysis and the positive/cooperative property of the error dynamics, two approaches were proposed for constructing the observer gains to achieve uniform asymptotic stability of the error system based on mixed-integer semidefinite and linear programs, and additional degrees of freedom are incorporated to provide potential advantages similar to coordinate transformations. The effectiveness of both observer designs is demonstrated through simulation examples.

Current economic and social realities of higher education have placed increasing emphasis on using Teaching Assistants (TAs) in the classroom. However, missing from the discussion is how prepared these TAs are for the rigors of teaching and the effects of the increasing emphasis on their education and the education of their future students. To better understand the process a TA underwent to learn to teach in a higher education classroom, the following study explores what teaching assistants within a Writing Program (WP) at a research-one university say about how they learned to teach writing. The study aims to explore what strategies future TAs relied on and how they experienced their training to teach in hopes of exploring the problem space of learning to teach writing. The literature review explores some themes researched in the history of TA training. The study itself is a focus group of 9 Graduate Student TAs at a research one facility. The research suggests that the complex negotiation of learning to teach is situated within the framework of multiliteracies in that future TA’s utilize available designs from all over their lived experiences, design them for their own course, and eventually redesign their courses and pedagogies with selected available designs. This research offers new ways to conceptualize TA training and make it more scalable to better serve future TA’s.

The importance of teacher collaboration and professional growth are highlighted by their inclusion in the 2015 Every Student Succeeds Act (ESSA). In ESSA, it is recommended that teachers are provided with opportunities to collaborate and participate in learning communities. The purpose of this action research study was to address the problem of practice of a lack of teacher collaboration and professional learning community (PLC) at Sun Valley High School (SVHS); a 9th-12th grade public school in southern California. Through previous cycles of research, an online collaborative space to foster and support teacher collaboration was created; the PLC Team Hub. This study examined the attitudes and experiences of three teachers participating in a first-year, cross-curricular PLC Team and their interaction with the PLC Team Hub. Data gathered includes survey data, teacher interviews, audio of PLC Team meetings, teacher-generated artifacts, and digital researcher journal. Results suggested that the PLC Team Hub was effective in facilitating teacher collaboration and communication for these teachers. Further, teachers reported that they observed evidence of cross-curricular student engagement and learning as a result of their participation in the PLC Team Hub. Recommendations focus on the future of the innovation and the need for institutional and administrative support to continue the PLC Team Hub at SVHS.

School belonging is critical to well-being among youth. However, scholarship on school belonging among Black youth has largely used deficit perspectives. Furthermore, there is a lack of social, historical, and culturally informed perspectives to examine factors that may promote or prohibit school belonging. Currently, there is limited research about how factors across socioecological levels impact school belonging among Black youth, and how this relates to behavioral health. In this mixed-method dissertation, I used phenomenological perspectives (i.e., teachers, Black youth) to examine factors that promote school belonging while accounting for manifestations of racism, then link this process to marijuana use. In Study 1, I used interviews with racially-ethnically diverse teachers (n=15) in Arizona to examine their perspective on factors which promote or prohibit a sense of school belonging. Additionally, I used Brown’s (2007) framework to identify culturally responsive strategies for promoting school belonging. Findings demonstrated that cultural humility, human connections, diverse literature, culturally aware assignments, and extracurricular involvement are critical factors that promote school belonging, while racism evidenced by racial discrimination, colorblindness, discipline disparities, and systemic racism created significant barriers to belonging. The culturally responsive strategies demonstrate unified efforts school systems use to support school belonging among Black youth. In Study 2, I employed cross-classified hierarchical linear modeling with data from the Arizona Youth Survey and structural indicators of schools and neighborhoods to examine the association between school belonging and lifetime time marijuana use among Black youth (n=6120). Findings demonstrated that school belonging was associated with decreased marijuana use, which significantly varied across schools and neighborhoods. Specifically, Black youth that attended schools with higher percentages of certified teachers and resided in majority White neighborhoods reported greater decrease in the association between school belonging and marijuana use, while higher neighborhood educational attainment was related to increase in the association between school belonging and marijuana use. Integration of the findings from these two studies demonstrate promotive factors for Black youths’ sense of school belonging, while acknowledging how racism is embedded within their daily environments. Structural changes addressing racism and supporting Black youth are needed across contexts.

Integrating agent-based models (ABMs) has been a popular approach for teaching emergent science concepts. However, students continue to find it difficult to explain the emergent process of natural selection. This study adopted an ontological framework–the Pattern, Agents, Interactions, Relations, and Causality (PAIR-C)–to guide the design of learning modules. This pre-posttest experimental study examines the effects of the PAIR-C module versus the Regular module on fostering students’ deep understanding of natural selection. Results show that students in the PAIR-C intervention group performed better in answering deep questions assessing the understanding of inter-level causal relationships than those in the Regular control group. Although students in both groups did not show significantly improved abilities in explaining the natural selection process for other contexts or significant differences in their abilities to explain other emergent phenomena, students in the intervention group demonstrated system-thinking perspectives and fewer misconceptions in their expressions compared to the control group. A close analysis of student misconceptions consolidates that the intervention group demonstrated drastically fewer categories and numbers of misconceptions while those in the control group did not show such drastic changes before and after the study. To precisely address misconceptions and further improve students’ learning outcomes, Epistemic Network Analysis was adopted to capture students’ misconception characteristics by examining the co-occurrences of different misconception categories as well as the relationship between misconceptions and PAIR-C features. The results of student learning outcomes and misconception characteristics collectively provide directions for improving the instructional design of the PAIR-C module. Furthermore, findings on student engagement levels during learning can also inform future design efforts. Overall, this project sheds light on applying an innovative framework to designing effective learning modules to teach emergent science concepts.

As an administrator, it is essential to understand the varying theoretical perspectives and frameworks surrounding leadership and organizational development that support employee and student success. After conducting the first two cycles of action research, it was confirmed that there was a need for an intentional focus on the employees’ experience and their professional development. This focus led to administering a distance mentoring program for higher education administrators. The distance mentoring program was a mixed-methods action research project that ran a total of eight weeks with an orientation, mentoring sessions and individual activities during the first five weeks, and individual interviews three weeks following the intervention. There were eight participants in the study who were paired into four groups of two in order to foster a mentoring relationship using the “other” mentoring model. The purpose of the study was to determine the effectiveness of the distance mentoring program with respect to increasing educational outcomes, innovation, job satisfaction, productivity, and strategic action planning for higher education professionals. The distance mentoring program was successful in generating innovative thoughts relevant to the participant’s workplace challenge, increasing job satisfaction, stimulating better solutions for strategic action planning, and creating in a positive impact on the mentoring relationship. Results surrounding productivity were mixed and inconclusive. The implementation of the distance mentoring program was designed to initiate dialogue, brainstorming, planning, and supportive measures by each participant and delivered the social and strategic elements necessary to achieve a more positive, productive, and successful work environment.

The role of lecturers at the University of Guyana has always included research. However, the productivity of these lecturers has historically been low. This dissertation examines the reasons for low research productivity among lecturers and attempts to understand the underlying concerns. Through a series of action research cycles, the researcher developed a conceptual framework that intersected intrinsic and extrinsic motivation, self-determination, and self-regulation. A subsequent intervention, professional learning related to action research, was conducted to ascertain whether action research as a methodology could provide lecturers with a new way of thinking about how research could be conducted. A concurrent quantitative and qualitative mixed-method action research design was used to determine the effects of the intervention. An online survey and one-on-one semi-structured online interviews were conducted to collect data, while data were analyzed using the Wilcoxon signed-rank test and thematic analysis. Findings indicate there was a significant increase in reported competence by lecturers.

What are the embodied educational experiences among students who were forced to migrate from war areas in Ukraine and study at Ukrainian displaced universities? Building on somatic literature and process philosophy, I developed embodied method of data collection and body-echo analysis to explore the complexities, entanglements and relationality of education and embodied experiences in the context of forced migration in Ukraine. The goal of this dissertation was to learn about students’ experiences of forced migration through an essentially embodied learning processes that integrate mental and physical capacities. I believe that students learn through sensing their way through forced migration, accumulating layers of kinesthetic information hidden in their bodies. More specifically, the students in this study moved either with Displaced Universities from the war areas in Ukraine or independently in several waves or enrolled at the Displaced Universities to receive their education in mainland Ukraine at relocated Displaced Universities. The key insights include 1) uniqueness of embodied experience(s) of forced migration for each student; 2) invisible or virtual university spaces created by forced migration in Ukraine; 3) displaced universities created a virtual relational space in Ukraine where university is people not building; 4) somatic practice allowed an entry point into the safe space of talking about forced migration; 5) unique reactions of students to the somatic movement; 6) sense of belonging to space and people; 7) students’ insights very often remain unfinished thoughts and students at times lack the language to talk about their experiences; 8) students educational trajectories should be viewed as unique experiences even when factors are the same or similar; 9) war is a continuous background of the experience even if students move to a safe place in a different country; 10) humor and care have a visible supportive and healing effects in the context of uncertainty. For this reason, I bring embodied experiences of students from Ukrainian Displaced Universities into education, and I expand the limits of cognitive thinking, and focus more into embodied learning through sensing and relating to one-self and others in the context of forced migration.

Second Language Learners face a unique set of challenges when it comes to the learning process. This dissertation study specifically focuses on those challenges and how to train teachers working within a co-teaching model in an international school in Bangkok, Thailand. Using the ideology proposed by Stephen Krashen as a part of his Input Hypothesis Theory and framing the results through the lens of Albert Bandura’s Self-Efficacy Theory, I studied the effects of a professional development model that focused on phonemic awareness, comprehensible input, and a collaborative teaching approach. Using this as my methodological framework, I found that teachers were able to improve their teaching skills and become more confident in their approach when provided with training that gave them specific responsibilities to address within the process of teaching. Through the use of pre-post surveys, interviews, and observations, I was able to examine how resource sharing and collaborative lesson planning allowed teachers to be more confident in their approach to teaching and their abilities to support students that were attending an international school that was a part of one of the most successful and academically rigorous networks of schools in the United States of America. It was through an intentional designation of tasks and a collaborative training approach that teachers were not only able to better understand the needs of their students but also find ways to work with and learn from one another in the training process. Ultimately, I discovered that allowing teachers to share resources and best practices allowed them to build quality and far more engaging lessons for their students.

This dissertation studies the differences in how men and women react to feedback or information about their performance in educational settings and how these differences might impact women’s decisions to stay away from traditionally male-dominated fields. The first chapter analyzes the gender differences in reaction to low performance during high school. I focus on the decision of North Carolina public high school students to enroll in advanced math or English classes after learning about their performance on statewide standardized tests in each subject. I find that women are more responsive to low-performing than men. Women that perform poorly on their tests are less likely than their higher-performance peers to enroll in advanced classes, while men's likelihood is the same regardless of performance. It has been documented that the probability of women continuing their studies in male-dominated fields -- like Science, Technology, Engineering, and Mathematics (STEM) and business -- is more sensitive to their performance in relevant courses at the beginning of college relative to men. The second chapter studies these gender differences in grade sensitivity during college. Using novel survey data, I estimate students' sensitivity to grades and find that women value an extra grade point average (GPA) unit more than men. I find that anticipated discrimination in the labor market of male-dominated fields is important to understand this gender gap in grade sensitivity. I further provide evidence of the gender differences in beliefs about labor market discrimination in different fields. The last chapter investigates the dynamic effects of feedback in an experimental setting. I explore how individuals update their beliefs and choices in response to good or bad news over time in two domains: verbal skills and math. I find significant gender gaps in beliefs and choices before feedback: men are more optimistic about their performance and more willing to compete than women in both domains, but the gaps are significantly larger in math. Feedback significantly shifts individuals' beliefs and choices immediately after receiving it. However, there is substantial persistence of gender gaps over time. This is particularly true among the set of individuals who receive negative feedback.
