The Perceived Impact Of Project-Based Learning (Pbl) On Middle School Students’ Science, Technology, Engineering, And Mathematics (Stem) Identity And Engagement, Jonathan Olivera

Theses and Dissertations

Despite multiple calls to action, the United States educational system is not producing enough viable contributors in the areas of science, technology, engineering, and mathematics (STEM). These fields continue to grow, and the STEM workforce continues to expand. However, the pool of citizens prepared to enter these professions is not keeping up with the demand. Part of this issue can be attributed to a diminishing interest in STEM by students, particularly during their identity forming adolescent years. Active learning strategies have proven successful in preventing this decline with project-based learning (PBL) being one of the most successful active learning strategies. …

The Chemistry Laboratory Experience Of El Camino Students While In Emergency Remote Teaching Due To The Covid-19 Pandemic, Shaun A. Cook

Theses and Dissertations

Future college environments, including those in chemistry, will entail flexible formats. The pandemic spurred appreciation of the need, and though it has largely passed, adaptability to multiple formats in the future has been a critical part of planning for a rapidly changing future. Experiences during the pandemic will guide pedagogical changes and practices in the future. At El Camino College in Southern California, the chemistry department provided varied laboratory instruction to students during Emergency Remote Teaching. Understanding the experience students had during this extraordinary time is essential. Students who took courses that had an online laboratory course completed a mixed-methods …

American Indian Culture And Secondary Science Curricula: Examining The Confluence Of Native Epistemologies And U.S. Public Education Science Standards, Molly Anne Wolk

Theses and Dissertations

Innate to the traditional science curricula taught under the auspices of United States public education are a Neoliberal axiology and Eurocentric epistemology (Howard & Kern, 2019) that do not meet the cultural needs of American Indian students (Cobern & Loving, 2001). It is inequitable that American Indian students do not see themselves and their cultures reflected in traditional public school science texts and curricula. At the confluence of often-undifferentiated science curricula and American Indian culture and language, there is a need for a responsiveness that benefits American Indian students. This present study illuminates the research question, “What is revealed about …

Changes In Teacher Thinking And Action In Response To The Next Generation Science Standards, Angela R. Bowden

Theses and Dissertations

This study examined the role of K-12 science teachers’ understandings and perceptions of the Next Generation Science Standards, implementation of the new standards in the classroom, and potential barriers to implementation as reform stakeholders had envisioned. Grounded in the relevant literature and working from the Teacher-Centered System Reform framework, this study employed a quantitative approach to data collection. The TCSR Model framed this study by linking teachers’ demographic and professional profile, teaching experience, professional development, district-level, school-level, and classroom-level contexts and illuminates the dynamic effect the factors have on teachers’ thinking and their practice. The study recognizes teachers’ knowledge and …

Making Sense Of School Reform: A Case Study Of Mathematics And Science Teachers' Sensemaking With One District's Differentiation And Detracking Initiatives, Katelyn Daplyn Skinner

Theses and Dissertations

The purpose of this case study was to examine how individual science and mathematics teachers within a particular high school made sense of a district differentiation effort. A focus on teachers' perceptions and interpretations of this effort was targeted through the theoretical framework of sensemaking. Two of the teachers were present for an initial detracking reform effort, which enabled the researcher to examine their sensemaking of both initiatives.

There were clear differences in the sense that teachers made of the differentiation initiative. Additionally, there were multiple factors that impacted teacher sensemaking; the district initiative was not one of these factors. …

Developing Conceptual Understanding And Procedural Fluency In Algebra For High School Students With Intellectual Disability, Andrew J. Wojcik

Theses and Dissertations

Teaching students with Intellectual Disability (ID) is a relatively new endeavor. Beginning in 2001 with the passage of the No Child Left Behind Act, the general education curriculum integrated algebra across the K-12 curriculum (Kendall, 2011; National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010), and expansion of the curriculum included five intertwined skills (productive disposition, procedural fluency, strategic competence, adaptive reasoning, and conceptual understanding) (Kilpatrick, Swafford, & Findell, 2001). Researchers are just beginning to explore the potential of students with ID with algebra (Browder, Spooner, Ahlgrim-Delzell, Harris & Wakeman, 2008; Creech-Galloway, Collins, Knight, …

How Does Youth Participatory Eco-Justice Action Research (Ypear) Affect The Development Of Environmental Literacy In Urban High School Students?, Joella L. Zocher

Theses and Dissertations

The field of environmental education (EE) has the aim of producing an environmentally literate citizenry that is not only aware of environmental problems, but motivated to work towards their solution (Stapp, 1969). However, much of the U.S. EE curricular focus has been on understanding the biophysical environment with rural populations, with little discussion about the environmental problems created by the dominant Western cultural norms (Kenis, & Mathijs, 2012; Malone, 2006; Prakash,1995). This study suggests in order to truly develop environmentally literate citizens who will work to change the oppressive habits of our dominant culture, people must be willing to enter …

Effective Elements Of Science Teacher Professional Development, Amy Jean Zientek

Theses and Dissertations

Educational reform efforts to improve students' learning outcomes are often present in teacher professional development opportunities; however, the structure and design of these opportunities vary and often focus on a homogenous student population; that is, White students in suburban schools. Reform efforts in teacher professional development that aim to educate teachers not only about science content and pedagogy, but also about practices that aim to reach a diverse student population is needed. This study examines three, science teacher summer professional development (PD) programs [SUN, SEPA, and CLA], and explores how programs affect teacher learning outcome(s) and any subsequent translation into …
