The overarching theme of this research was to explore different aspects of the science, technology, engineering, and math (STEM) education experience across cultures and contexts in two engineering education communities, higher education and K-12. This dissertation offers new perspectives and resources to the engineering education community and…

Problem-solving, collaboration, and adaptability to in-person and virtual environments are critical for success today. Therefore, brick-and-mortar and online instructional models have shifted to ensure that K-12 students are prepared with these skills for 21st-century challenges. Grounded in systems theory, the study examined the inputs,…

The purpose of the investigation was to determine if there was a difference in student performance on the NYS Mathematics State Assessment between schools that implemented PBL versus those that did not. The aim was also to determine if there was a difference in students' and teachers' attitudes about the school community, specifically in rigorous…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…

Educators and policymakers advocate for the implementation of problem-based approaches to STEM education in K-12 classrooms to help students develop 21st-century skills such as the ability to think critically, collaborate, and problem-solve. The first exploratory case study in this three-article dissertation examines how students engage in…

Problem-based learning (PBL) is a method of instruction that challenges students to answer questions in a practical manner using their understanding of learned course content. The question at the heart of this study concerns if and how faculty in one institution are currently using PBL. I used an exploratory descriptive case study to research the…

Gender inequalities continue into the 21st century and STEM was a major area of emphasis. Educators need to focus on female students to build their self-efficacy and critical thinking skills. The purpose of this study was to determine if problem-based learning (PBL) improves female elementary students' self-efficacy and critical thinking skills.…

In an ethnographic study of one high school mathematics department made up of four African American teachers, I explored their co-construction of knowledge about teaching mathematics for social justice. This began with an in-depth study of each teacher's professional identity, their emotional connections to teaching in their local African American…

The increasing complexity of global challenges demands a STEM-enriched approach to learning for all students, regardless of their future career paths. Challenge-Based Learning (CBL) is a pedagogical method to foster a STEM-enriched education, engaging students in the design of societally impactful, interdisciplinary solutions. To investigate the…

The purpose of this action research study was to explore the impact of problem-based learning on science instruction in my eighth-grade college preparatory classroom. Constructivism was the framework for this study. Problem-based learning is based on constructivist principles, and it served as the instructional model for this study. PBL can foster…

Educators are often looking for ways to increase engagement and academic achievement in their classrooms; therefore, the problem addressed in this study is the decrease in academic achievement caused by a low level of classroom engagement amongst high school seniors. The purpose of this qualitative action research study is to increase academic…

STEM education awareness, advocacy and literacy are paramount to the nation's global competitiveness, innovation, and security. Technology will be the vanguard of the 21st century and the effectiveness of STEM education will determine if we can solve real-world problems such as maintaining national defense, protecting the environment, medicine,…

Problem-Based Learning (PBL) is an effective instructional methodology used in higher learning. The purpose of this qualitative descriptive study was to explore what undergraduate engineering students perceive as barriers to the implementation of PBL in engineering courses at higher learning institutions in the Southwest United States. This…

The purpose of this qualitative hermeneutic phenomenological study was to understand the lived experiences of teachers in kindergarten through first grade utilizing digital technologies to engage elementary students during mathematics instruction. This phenomenological study was guided by the following research questions. (1) How do elementary…

The purpose of this qualitative descriptive study was to explore how high school teachers describe problem-based learning as an instructional model for student learning in various academic disciplines in the United States. The research was grounded in constructivist learning theory and Problem-based learning (PBL). The study addressed two research…
