The role of peer and teacher mediation in discussions about two original scientific texts in the final year of high school in Brazil is explored in this study. A text by James C. Maxwell, deals with the characterisation of light as an electromagnetic phenomenon, and refers to the continuous manner of the distribution of energy by radiation in…

Building on previous research that has described the underrepresentation of women of color in science fields, this paper presents case studies of Black middle school girls to examine how their science identities developed over space and time. Data were collected over the course of their seventh-grade year in both in school (science classroom) and…

Society's progress and living standards depend on the exploitation of raw materials. For centuries, its exploitation had kept pace with humanity's demand. Lithium is a critical element, essential to the development of green technologies, to decarbonization process, and for our daily life. In Portugal, there are high-quality Lithium deposits, with…

Diverse backgrounds, viewpoints and experiences in science, technology, engineering and math (STEM) are vital for innovation and creativity in STEM; and yet, racially minoritized groups, such as African Americans and Hispanics, remain underrepresented in the STEM K-12 and career pipeline. Studies show that exposure and access to STEM experiences…

A feature of student--teacher--scientist partnerships (STSPs) involves students working with scientists for the purpose of helping them learn more about how scientists work and think. Previous research on STSPs has generally focused on identifying the best practices of partnerships and on identifying challenges of these partnerships. The study…

Scientists' writing includes organized data, calculations, sketches and models, inventories and lists, timelines, detailed descriptions, locations, conditions, actions, schedules, information about variables, goals, hypotheses, research, notes, summaries of experiments, and reports to others (Fulton and Campbell 2014). By using scaffolded science…

To address complex geoscience questions, communities with a variety of experiences and perspectives are needed in local workplaces and institutions across academia and government. To achieve this goal, geoscience needs leaders who are champions of diversity and who have positive attitudes toward others and act upon these attitudes to become change…

Over the course of middle childhood, children's interest and beliefs about their own capacities for success in science often decline. This pernicious decline is especially evident among underrepresented groups, including girls, members of some racial and ethnic minorities, and children from lower socioeconomic backgrounds. The present research…

Science, technology, engineering, and mathematics (STEM) education has become an essential part of school curricula and is crucial to filling future jobs, so research examining ways to increase STEM motivations is essential. While an abundance of research has examined STEM in relation to traditional media, research examining the impact of digital…

STEM (Science, Technology, Engineering, and Mathematics) will drive the economy of the West in the future. The competitiveness and strength of the U.S. economy are reliant on a workforce with the skillset necessary to ensure that the nation remains a powerful force in the global economy. As a result, the under-representation of women in STEM is a…

There is a current push to understand and address the under-representation of Black folks in physics, and STEM more broadly. This dissertation presents research that explores this lack of representation through studies of identity and practice, premised on an understanding of systems of oppression operating within the culture of physics. This work…

This dissertation proposes to answer several questions that arise from the actions of American scientists between 1840 and 1900. How did the broader organization of science in the late nineteenth century create a system of professional disciplines? Why did the American Association for the Advancement of Science (AAAS) form, and why did specialized…

Kathleen Allen's reverence for the stories of women naturalists spanning from the seventeenth through the twentieth centuries, and their parallel scientific interest in the documentation of life cycles through art and narratives, gives support to the child in history and nature that is so central to Montessori formal research and discipline. The…

Several major organizations have recommended revisions to mathematics requirements for biology majors. To determine whether these changes would benefit future biologists, we investigated mathematics use in research biology. We surveyed prominent journals in high and low math-use areas for articles referencing the use of quantitative methods. In…

Over the years neoliberal ideology and discourse have become intricately connected to making science people. Science educators work within a complicated paradox where they are obligated to meet neoliberal demands that reinscribe dominant, hegemonic assumptions for producing a scientific workforce. Whether it is the discourse of school science,…
