To make sense of our interconnected and algorithm driven world, students increasingly need proficiency with computational thinking (CT), systems thinking (ST), and computational modeling. One aspect of computational modeling that can support students with CT, ST, and modeling is testing and debugging. Testing and debugging enables students to…

While countless studies have collected data on the effectiveness of various problem-solving models, few have attempted to identify which components of the training process are helpful to participants. Two teacher teams consisting of seven participants were trained in an adapted version of the Team-initiated Problem Solving (TIPS) model, observed…

Graph Signal Processing (GSP) plays a crucial role in addressing the growing need for information processing across networks, especially in tasks like supervised classification. However, the success of GSP in such tasks hinges on accurately identifying the underlying relational structures, which are often not readily available and must be inferred…

The purpose of this qualitative descriptive study was to explore how church members describe the influence of pastoral transformational leadership to achieve the church's organizational vision and goals. The theoretical foundation for this study was Bernard Bass' (1985) transformational leadership theory. The research was guided by four questions,…

This dissertation in practice investigated and addressed the issue of low faculty engagement with instructional design support (IDS) office support services at a regional comprehensive university in the United States. The Performance Improvement/Human Performance Technology (PI/HPT) model used in this study is a practitioner-based performance…

The study examines the perspectives of using the Desmos calculator of Algebra I students' conceptual understanding and procedural fluency to write, graph, and solve linear equations in Algebra I STAAR. While the students have continuously used technology for mathematics assessment, emergent bilingual students in South Texas still need help passing…

One of the core dimensions of historical and social science inquiry is "[d]eveloping questions and planning inquiries" according to the National Council for the Social Studies' College, Career, and Civic Life (C3) Framework. Yet existing education research, instructional resources, and assessment have ignored how students frame problems…

This study investigated how problem-solving videos can be used in video-mediated professional learning to support secondary preservice mathematics teachers (PMTs) in developing teacher knowledge for noticing student thinking in the context of the derivative concept in calculus. A model of the trajectory of PMTs' noticing was constructed as six…

Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well…

Developing students' creative problem solving skills should be one of the top goals in general education. One teaching model that was developed to increase students' creative problem solving abilities is the Real Engagement in Active Problem Solving (REAPS) model. This model was used as an intervention in classrooms in many studies. However, the…

The purpose of this case study was to examine how one high-performing California TK-6th grade public elementary school had committed to the development of 21st century skills. Specifically, this study sought to identify the practices and structures at Utopia Elementary that allowed students of low socio-economic status and students with an…

Self-determination has been identified as a predictor of post-school success for students with disabilities (Test et al., 2009); however, students with autism spectrum disorder (ASD) continue to experience poorer outcomes than their peers without disabilities in the areas of education, employment, and independent living upon leaving high school…

Research on mathematical modeling is growing rapidly in the field of mathematics education, and there are numerous benefits of engaging students in modeling activities. However, mathematical modeling is still marginalized in mathematics instruction. In order to understand the challenges and obstacles secondary teachers face to incorporate modeling…

This study examined how or why teachers' perspectives on the importance of infusing self-determination, including problem-solving, goal-setting, and choice-making, might help determine the benefits and use of self-determination as an instructional intervention. The self-determination theory and the causal agency theory were the theoretical…

This dissertation reports the research methodology and findings of three studies focused on mathematical modeling as a structured problem-solving process where the student translates relevant details from a situation, event, or phenomena in daily life into mathematical language with mathematically-defined structures and operations, which form the…
