This is potentially the first study that addressed the Puerto Rican high school students' chemistry knowledge acquisition using traditional teaching and Physics Education Technology. The problem addressed by this quantitative comparative quasi-experimental study was that students' showed a disadvantage on chemistry knowledge acquisition over other…

The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students' explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry,…

Physics classrooms, from high school through graduate school, chronically enroll far too few women, people of color, English language learners, and low-income students. Research suggests students' science identity functions as a strong indicator for their continued pursuit of physics coursework and careers. Further research indicates students'…

The post-pandemic classroom dealt with not only the mental health struggles of educators and students, but also the technological and virtual learning dependence in a time ridden with misinformation. At this time, it was important to not only consider the purpose and intent of science education as a learning experience, but also pedagogical…

Different teaching and learning strategies have informed physics educators on addressing the cultural meanings and practices of physics that have sustained homogeneity within university programs. However, literature evidence physics learning environments are under-theorized in dismantling homogeneity and conceptually changes physics student…

The under-representation of women in undergraduate science courses is well-documented. One significant challenge is that women may both perceive and receive less recognition from their science peers about their abilities as scientists than men. Here we investigate the presence and nature of such gender biases in peer recognition in the discipline…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

Conceptual approaches to contemporary physics topics pose many learning challenges. One factor influencing knowledge integration is a student's epistemological framing. Epistemic frames provide a context within which a particular situation is perceived, interpreted, and judged. The utility of an epistemic frame is context dependent, and the…

It has been well-establishing in the field of educational research that traditional educational methods such as passive lectures and labs where students follow pre-designed procedures to verify information already told to them are not effective for promoting meaningful and lasting conceptual understanding. Alongside this knowledge have come a…

This dissertation proposes novel Domain Adaptation (DA) methods in real-world industrial settings, where the availability of labeled data is limited and test data can significantly differ from training data. Particularly, our research addresses key challenges in DA, including the applicability of DA methods in industrial settings, strategies to…

Physics education researchers have called for a shift from traditional laboratory (lab) instruction to labs that focus on the development of experimental skills. Although research has demonstrated the efficacy of such reformed labs, much work remains to determine what these labs can and should teach students and how best to achieve these goals.…

Understanding human behavior and reasoning is essential for developing successful instruction. Discipline-based education researchers have examined how students learn, informing the development of successful instructional strategies. Researchers have also identified barriers to the successful implementation of such strategies. This work utilizes…

Spatio-temporal processes are ubiquitous and prevalent across disciplines. Understanding the mechanisms underlying processes and integrating this information into models is of great interest, as it can improve forecasting accuracy and align with scientific motivation. Examples of such models include Partial Differential Equation (PDE) Models or…

This study employed a qualitative case study design to explore participants' perspective on learning STEM subjects through immersive mobile technologies. Immersive mobile learning (IML) is the learning approach that provides learners with immersive experiences and access to educational content ubiquitously using portable electronic devices.…

Challenges to integrating technology into educational institutions pose a significant issue that impacts students' performance and accomplishments. The research problem addressed through this study was that secondary school physics teachers were challenged to integrate information and communication technology (ICT) in a southwestern state of…
