This study addressed the following research questions: 1) What is the effect of differentiated gamified instruction on the cognitive engagement of ninth grade students in the unit of plant and animal systems? 2) What is the effect of differentiated gamified instruction on the behavioral engagement of ninth grade biology students in the unit of…

The U.S. Education system is founded on a Eurocentric focus of curriculum, and students of color are not achieving as high as white students on the National Assessment for Education Progress in science. This research aims to repay the education debt owed to students of color by decolonizing science curriculum through the implementation of lessons…

Ninth-grade students with learning difficulties typically underperform those without learning difficulties, particularly in an integrated geoscience course. Despite the growing demand for STEM careers, science remains challenging to understand and inaccessible to many, especially those with learning difficulties (Vavougios et al., 2016).…

This three-manuscript dissertation used a rapid PDSA to improve teacher efficacy concerning designing and teaching an unleveled 9th grade science class. Leveling and tracking can lead to inequitable outcomes and experiences for minoritized students. However, designing and implementing effective heterogeneous, unleveled classes that meet the needs…

Many efforts to reform science educational standards and structure have placed an emphasis on directing learners to communicate about concepts using external representations (ERs). Techniques to develop competencies with ERs often ask learners to develop understanding outside of a physical context while concurrently making connections back to the…

This quantitative study examined the impact of a multi-subject double-dose STEM intervention on the academic achievement of underprepared 9th-grade males. The intervention consisted of heterogeneously grouped core classes of Algebra 1 and biology accompanied by a second multi-subject (Algebra 1 and biology) support class. This nine-week study did…

This study focuses on at-risk students entering 9th grade in Cambridge, MA and ways to increase their connectedness and science learner identity. At-risk students were invited to participate in a research-based, summer intervention program called Rise Up for four weeks prior to entering 9th grade in the fall. Students were grouped into three…

This comprehensive study explores the experiences of underrepresented students who have participated in informal science education programs at the American Museum of Natural History (AMNH). Using qualitative methods, including interviews and participant observations, the research uncovers transformative insights shaping the educational landscape.…

This dissertation is a case study of a school district in the Pacific Northwest that developed three-year high school science curricula using a Physics First course sequence (Physics, Chemistry, Biology), with the crosscutting concept "Patterns" as the central theme of the courses. The purpose of the study was to examine the impact of…

Understanding how to foster belonging and ensure equitable engagement in STEM fields for diverse students is a critical need in education today. Despite substantial growth in the STEM workforce (Bureau of Labor Statistics, 2023; NSF, 2023a), there remain persistent gender and racial/ethnic gaps in students' access to advanced STEM education,…

This dissertation focuses on the development and implementation of an action research study that seeks to determine the impact of integrating literacy strategies in the biology classroom on standardized test scores. The teacher-researcher identified the problem of practice in her classroom after four years of observation of ninth-grade biology…

Science, technology, engineering, and mathematics (STEM) education is an economic opportunity for an urban school district in Tennessee. Lack of interest in STEM courses was throughout schools with underrepresented populations. An urban district in Tennessee with few schools implementing STEM initiated instructional practices to increase…

This qualitative, phenomenological research study explores the best practices that secondary Grades 6-12 educators employ when using microcontrollers in the classroom. Governmental and private organizations have investigated and promoted the importance of Science, Technology, Engineering, Math (STEM) and computer science in education (Code…

Current research has shown that writing to learn strategies have a positive impact on overall student learning. However, previous studies mainly assessed student learning through instruments that have been self-designed by researchers and there is little research examining relations between writing to learn strategies and science related context…

The purpose of the study was to explore the relationship between the implementation of freshman academies and student achievement in math, English, and science in schools in Arkansas. The study presents a review of the literature that discusses the ninth-grade year and the use of freshman academies to improve student achievement. The study…
