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…

To make sense of our interconnected and algorithm driven world, students increasingly need proficiency with computational thinking (CT), systems thinking (ST), and computational modeling. One aspect of computational modeling that can support students with CT, ST, and modeling is testing and debugging. Testing and debugging enables students to…

Educators have struggled with maintaining student engagement in science, especially as students transition from primary to middle school and upper grades (Vedder-Weiss & Fortus, 2012). A recent push in science education has been the adoption of the Next Generation Science Standards (NGSS), released in 2013, whose development was guided by…

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…

Efforts to understand changes in teacher curricula following the adoption of reform-based standards, such as the "Next Generation Science Standards" (NGSS) remain incomplete and prior scholarship has identified several topics in the standards (e.g., nuclear chemistry and kinetics) that remain infrequently addressed in teachers'…

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…

Our nation has declining participation in science and technology fields, even though in the United States we have seen an astounding collection of innovations in technology, communication, the Internet, and financial products. This lack of participation is even more noticeable for students with learning disabilities (SWLD) when compared to general…

Community driven science has emerged as a way to engage participants in learning about science while giving them a deeper understanding of what it means to do science and identify as one who does science. This multi-method case study investigated how secondary science preservice teachers experienced a community driven science project within the…

Culturally Relevant Education (CRE) focuses on the design of curricular materials that strengthen students' cultural identities while teaching classroom content and science practices. While examples of CRE in science continue to grow, the identities and cultures of the designers are often different from those of the students and communities in…

Over the years, the evolution of science along with technology, engineering, and mathematics has been noticeably evident while science education, on the other hand, has shown little development. The research study aimed to investigate future change initiative implementation in secondary science curricula. In addition, the purpose of the research…

The purpose of this study is to understand how secondary science teachers conceptualize student science identity and the impacts of this thinking on actions and planning with teaching. Research on how science identity impacts college students is more robust while little research looks at the impacts of secondary science teachers on science…

"Citizen science" popularly refers to a participatory approach in which lay persons voluntarily contribute data toward scientific enterprise. Although citizen science may provide unique opportunities for pre-college students to engage in data-intensive science practices, little is known about whether or how citizen science interacts with…
