Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…

Scientific literacy is an increasingly important skill for today and tomorrow's citizens. Encapsulated in the definition of being scientifically literate, one must be knowledgeable about science and technology in context and be able to interpret and communicate the information well. Introductory science courses, like general chemistry, are key…

Knowledge-producing practices in sciences and engineering increasingly use computational means for modeling and working with data. Despite consensus regarding the importance of computational thinking in science and engineering, scholars differ in conceptualization of the primary purposes and role of its integration in K-12 science (Kafai &…

As science teachers gain increasing access to resources through an ever-expanding resource system, the study of how science teachers decide which resources to use and how to use them becomes increasingly important and complex. When science teachers exercise agency to select and adapt resources in alignment with their context, teaching and learning…

The purpose of this qualitative descriptive study was to explore how science students described their experiences of collaboration in a virtual learning environment at a community college in the Midwestern United States between 2020 - 2022. The literature review indicated the need to understand how science students described their experience of…

Citizen Science is emerging as an innovative strategy to engage K-12 students in authentic science practices and relevant, real world phenomena. Citizen science is traditionally an informal science experience, with members of the public choosing to participate in the scientific research process through contributing data or other related efforts.…

This dissertation investigates the voluntary usage of clickers to answer in class multiple-choice questions in general chemistry courses and its effect on student performance. The first study explored the demographic composition of two sequential introductory level chemistry courses over six terms. No difference in voluntary usage of the clicker…

Distance courses are in high demand, post-secondary institutions are being encouraged to offer more. Some studies have found distance science classes to be as effective in content and student success, as on-campus courses. Distance courses often require greater self-motivation and study skills and as a result, the success of students in distance…

Science reforms in the United States' education systems have been ongoing for over the last 50 years. These reforms are continually revised in response to the demand to increase employment in STEM careers. The Next Generation Science Standards (NGSS) released in 2013 are the most recent standards-based science reform effort created using years of…

Learning effective science writing is an important component of becoming a scientist, but it can also be difficult to master. Even though the lab report has a long history in science education, there are still lingering issues that impact life science instructors and students. This dissertation is a coherent body of three interrelated research…

Science classrooms often marginalize students of color, particularly Black and Brown boys, by devaluing their perspectives and supporting narratives that reinforce long-lasting deficit mindsets that sustain practices that keep Black and Brown boys in the margins. Using a Critical Participatory Action Research methodology, this qualitative research…

This mixed methods study explored how elementary teachers reported using a commercially published instructional unit to plan and deliver science instruction in their elementary classrooms. Of particular focus is what elements of the program teachers eliminated during planning and instruction, what outside materials teachers added to instruction,…

The implementation of California Assembly Bill (CAB) 705 has impacted how students enroll into Physics courses. This paralleled anecdotal evidence of a decline in student mathematical abilities. The goal of this research study was to determine the existence of a relationship between CAB 705 and student success in specific Physics courses. This…

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…

The purpose of this teacher-practitioner research study was to examine how elementary teacher candidates engaged in sensemaking about the learning process within the Next Generation Science Standards (NGSS) and to further examine how they engaged in sensemaking about NGSS teaching and curriculum development. Interviews and course artifacts from 14…
