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'…

Contributions to conservation biology research are traditionally approached from an ecology and evolutionary biology perspective, but education research can be equally valuable. Population genetics research can inform management decision-making while education research can improve how we teach conservation. My dissertation tackles conservation…

Parental perception of the importance of science education and parental perceptions and use of active learning and inquiry-based practices in the context of homeschool science education represent a clear gap in the existing literature. This quantitative survey research study was designed to discover, analyze, and quantify parents' perceptions of…

Essential to a flourishing society in a changing environment, knowledge creation has become pervasive across social sectors. Creative work with knowledge and ideas requires dynamic forms of collaboration in which individuals adapt goals as new advances and problems emerge. To prepare students for creative knowledge work, new classroom designs…

The objective of this dissertation was to explore how the principles of culturally sustaining pedagogy (CSP) can inform the design of a junior high school curriculum to enhance science learning by providing meaningful learning experiences to all students. The transformative paradigm provided a framework used as a lens to emphasize the importance…

The Framework for K-12 Science Education and the Next Generation Science Standards propose that students learn concepts and practices related to engineering as well as science. Currently the research surrounding how engineering practices through engineering design are implemented in the life sciences such as high school biology is limited. To…

This study was an action research self-study that examined my role as a teacher educator supporting a resident teacher in learning how to design inquiry-based culturally responsive science lessons. I explored my own growth in understanding how to act as a teacher educator to provide appropriately scaffolded support to promote learning for a…

Motivation, belonging, and inclusion are all critical factors for student success but can be difficult to support in asynchronous online courses. Active learning and required group work have been shown to increase student motivation in in-person and synchronous online courses, but little is known about their impact in online asynchronous settings.…

Contemporary education research seeks causal inferences in order to guide policy and practice. Often well-controlled quasi-experimental and experimental designs are used as they are very useful for supporting and contextualizing causal inferences. Nevertheless, individual studies, even high-quality, resource-intensive randomized controlled trials,…

This dissertation explores the integration of Place-Based Scientific Inquiry (PBSI) into science education through participatory design-based professional development for instructors at Sky School, an outdoor education program in southern Arizona. PBSI emphasizes student-centered, inquiry-driven, experiential learning grounded in outdoor contexts.…

This qualitative case study investigated the implementation of the Next Generation Science Standards (NGSS) by sixth-grade teachers in diverse educational settings within the Central Valley of California. The research focused on identifying the practical successes and ongoing challenges faced by educators in elementary and middle school…

Although many undergraduates begin college as STEM majors, attrition rates from the field are high and numerous reports suggest that evidence-based teaching methods are critical for retention. Despite educators' research and near consensus that active learning is more effective than lecture, there are many types of active learning and the…

Nearly half of all U.S. students who declare science majors in college do not graduate with science degrees within six years. Improvements in science outcomes are linked with active-learning pedagogies such as Course-based Undergraduate Research Experiences (CUREs). However, despite the need for education reform particularly in Alabama,…

Project-based learning (PjBL) instruction is an inquiry-based method that is beneficial to student achievement and their exploration of 21st-century learning skills, but there is a gap in the literature about how Grades 6 to 8 teachers feel about PjBL and its implementation. The research problem was science teachers in the United States were not…

This action research dissertation provides an overview of inquiry based learning in online general chemistry course. Due to the COVID-19 pandemic, many science course have been converted to an online format. In order to increase student learning and attitudes in online chemistry class, two inquiry based learning activities were developed and…
