Learning To Teach Prospective Elementary Teachers: A Narrative Inquiry Of A Newer Mathematics Content Instructor, Kelsey Quaisley

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

Learning to teach mathematics content courses designed for prospective elementary teachers (PTs) is challenging. Mathematics content instructors must be prepared to not only teach mathematics content, but engage PTs in understanding children’s mathematical thinking strategies, learning trajectories, and misconceptions (Carpenter et al., 1996; Carpenter & Moser, 1982; I et al., 2020). When considering how instructors might best be prepared and supported, however, one must recognize that there is significant variation in the backgrounds and expertise of mathematics content instructors (Masingila et al., 2012; Yow et al., 2016) and little is known about the preparation, knowledge, and experiences of mathematics content …

Exploration Of The Lived Experiences Of Native American Science Teachers Of The Great Plains: A Narrative Inquiry, Uma Ganesan

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

The complicated history of the education of Native American children through U.S. government-sponsored practices has led to the elimination of the Native children’s sense of Indian identity, culture, and language (Noel, 2002). In addition, increased emphasis on standardization and high-stakes accountability under the No Child Left Behind Act of 2001 has resulted in less culturally responsive educational efforts and more Indigenous students left behind in school systems (Castagno & Brayboy, 2008). This has led to Indigenous students being underrepresented in science, technology, engineering, and mathematics (STEM) fields where they account for only 3% of STEM workers (Fry, Kennedy, & Funk, …
