This study explores the rationale, efficacy, and social validity of a professional development model designed to move elementary school science activities closer to the practices of working scientists as required by the United States' "Next Generation Science Standards". The model is culturally sensitive and aims to create experiences…

Recent reforms in science education call for efforts to engage students in authentic and sustained science practices. In order to engage students in authentic science practices, students need to enact epistemic agency over the processes of inquiry in line with how knowledge is constructed and practiced in the real world. A critical research…

This quantitative causal-comparative study investigated the growth performance scores of English learners in grades three through five in reading, mathematics, and science in four English language educational programs: English as Second Language (ESL), Transitional Bilingual Education (TBE), Dual-Language Immersion (DLI), and No Services. I used…

The U.S. is deficient in producing science, technology, engineering, and math (STEM) professionals. Competent problem solving is a desirable educational outcome pertinent to STEM education. Research has demonstrated the effectiveness of teaching task-specific problem-solving skills using behavior-analytic tactics. Learners have been taught to…

In 2019, the U.S. is still facing a shortage of science, technology, engineering and mathematics (STEM) workforce that is capable of solving social and economic challenges in 21st century worldwide. Numerous studies have explored the influence of integrative STEM approaches on developing student interest and career aspiration in STEM. Building on…

This dissertation explores the ways in which preservice science teachers enact a critical race curriculum in majority-Latinx elementary classrooms. Even though Latinx students represent the majority in public schools, their ability to move forward in their curricular experiences are limited if teachers do not provide equitable opportunities to…

This study investigates the implementation of science instruction in a low SES/high minority district, and the experiences of individuals in an elementary principal network who inform science standards and curriculum implementation. This study specifically examines how principals make sense of science policies. Given the intra-school and…

Research shows that many citizens have misconceptions about the source of their food and fiber. Several organizations have developed agriculture-based curriculum in an effort to increase agricultural literacy. Although there are a number of resources available to teachers, it is unclear which resources are being used and how often they are being…

Nebraska is committed to pursuing a new vision for science education based on "A Framework for K-12 Science Education" (NRC, 2012), that advocates for rigorous, high-quality science education for all students. Following an ambitious four year timeline, Nebraska is working to develop new assessments aligned to and designed for these…

This qualitative research examines design failure within a 5th grade science classroom that embedded engineering design activities. In adhering with a situative learning perspective, the goal of this research was to understand how design failure was portrayed to students through the written and enacted curriculum and in turn, how students…

The NRC (2012) Framework and the ensuing Next Generation Science Standards (NGSS) have brought crucial shifts in the goals for students' science learning. Teachers bear the responsibility of translating the three-dimensional vision of student learning articulated in these documents in classrooms through instruction. Central to the idea of…

Purpose and Method of Study: The purpose of this study was to compare the effectiveness of two approaches to professional development methodologies implemented in public schools. A quantitative, correlational research design was employed to determine whether the academic success in the core content areas of reading, writing, math and science could…

This study explores how K-8 critically conscious dual-language science teachers (CCDLSTs) working with bilingual learners (BLs) practice their critical consciousness via the four tenets of dual-language education: ideological clarity, pedagogical perspective and clarity, access for all, and equitable spaces (IPAE). This study is informed by the…

This study provides a qualitative approach to the issue of student engagement with a particular focus on urban area young learners in 4th grade science classes. Each class consisted of approximately 25 students. The students were given Interactive Notebooks to see whether this intervention helped promote greater engagement with the science…

In this study, I conducted three separate, but interrelated studies that examine the ways preservice teachers (PSTs) generatively developed youth-centered, equity-oriented pedagogical imaginaries in their methods courses and how they enacted these practice(s) in their field experiences. The purpose of this dissertation is to understand how and in…
