Concept inventories are widely used in physics education research, yet numerous studies show that concept inventories measure dramatically different learning gains in different demographic groups. Prior studies show that the performance gaps between demographic groups are already present in their preinstruction responses, suggesting that the…

Students entering high school often bring misconceptions about the nature of science and experimentation with them from middle school. Many also bring a belief that they are not a "science kid" and, therefore, cannot be a strong student in Biology. This belief can lead to a lack of self-efficacy and of student agency in the classroom.…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…

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…

This dissertation focuses on three manuscripts all related to bolstering science achievement through recommendations from the National Research Council (NRC) regarding the teaching and learning of science. The manuscripts address meeting the NRC's call to incorporate curriculum and assessment that lead to more in-depth knowledge that can be…

Nature of Scientific Knowledge (NOSK) and Nature of Scientific Inquiry (NOSI) are important components of scientific literacy and important educational objectives in science education. Recent literature theorizes that understanding both NOSK and NOSI increases students' understanding of science content knowledge. However, this assumption has yet…

High school students' chemistry self-efficacy (CSE) and scientific identity (SI) are not well understood in the high school chemistry classroom. The purpose of this research was to quantitatively investigate the interaction between gender and giftedness on students' CSE and SI in a suburban high school chemistry classroom, with and without…

This study investigated the integration of Citizen Science projects in high school science classrooms, aiming to discern the prerequisites for their successful implementation. Qualitative data collection methods were employed to illuminate how six high school Environmental Science teachers incorporated these projects into their curriculum and…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

Reading proficiency is particularly crucial for adolescent students who are expected to adopt and approximate a multitude of authentic literacy practices in several different content areas within the span of a single school day. A large number of adolescent students are failing to master basic levels of reading, and are thus uniquely disadvantaged…

This study investigated the intersection of literacy instruction and high school science teaching in response to low proficiency levels in these areas and interest in pursuing STEM careers among U.S. high school students. Participants reported using close reading practices combined with inquiry-based science instruction to enhance students'…

This paper aims to understand the barriers that face access to the arts in rural high schools and to offer a selection of potential change ideas to combat these barriers that exist in school settings. The literature review shows that access to the arts in rural communities is a barrier to complete education for school aged children because rural…

This dissertation is an invitation into our beloved biology classroom. Weaving hermeneutic phenomenology and critical participatory teacher action research, this study investigated self as teacher and two cohorts of student participants in a high school biology experience utilizing an 'Aina Aloha praxis. Articulating my ongoing 'Aina Aloha praxis,…

Health and biomedical science courses are meant to teach students the skills they need to be career ready; this includes digital literacy skills as technology in healthcare continues to grow. Blended learning is an instructional strategy that uses face-to-face and digital learning activities and has been shown to improve the digital literacy…
