In the K-12 classrooms, science teachers are increasingly using digital interactive textbooks to improve instruction. However, limited research exists on the Title I science educators' experiences with digital interactive texts in Title I middle schools. The purpose of this qualitative study was to explore the perceptions of these Title I science…

A major goal of science education is to produce students who are scientifically literate, meaning that students can not only understand scientific texts, but also use scientific information to make informed decisions related to scientific issues. Unfortunately, students in the United States have below proficient science ability, meaning the…

Mathematics courses should prepare students to use mathematics in a range of contexts, including science. However, students often struggle in applying mathematics in physics courses, even when they understand the mathematical content (Rebello et al., 2007). Often the root of this struggle is attributed to the "student" or the…

The curriculum used in educating young people has the ability either to serve as a catalyst for the development of a science identity or potentially sway individuals away from the fields of science, technology, engineering, and math (STEM). This study critically analyzed gender representation across 10 secondary education biology/life science…

Understanding how student characteristics affect learning in chemistry can influence the pedagogical strategies employed by chemistry instructors. Previous studies have investigated the effects of characteristics including prior knowledge, math ability, and motivations on course performance. Student characteristics can also influence study…

Advocating for the laboratory method was a distinguishing feature of textbooks as "physics" displaced "natural philosophy" in American schools during the second half of the nineteenth century as the dominant tradition of teaching physical science. This dissertation examines digital editions of textbooks in common use during the…

Most students begin their university studies with adequate mathematical skills to succeed in general chemistry. However, students have a demonstrated difficulty with the application of math in a chemistry context. The ability to apply skills to new contexts is known as transfer, and understanding and enhancing transfer of graphing skills into the…

The purpose of this Executive Position Paper project was to develop educational resources to support the teaching of nature of science topics to undergraduate students at Delaware Technical Community College. The investigation was driven by two exploratory projects and a review of the literature. The first exploratory project examined the…

The theory of evolution is the central combing theory that brings together all the tenets of biology that bring about a solid understanding of life. It is also one of the most controversial scientific theories of all time and is widely rejected by about 40% of the general public in the United States. One of the biggest reasons for low evolution…

This dissertation investigates the application of network models in educational assessment across diverse learning settings, encompassing both clinical and classroom environments. As educational paradigms shift and digital tools become more embedded in learning processes, traditional assessment methods often fall short in effectively capturing the…

Language is central to education, being the core medium of instruction. Researchers and practitioners have long used manual methods to analyze instructional language like classroom discourse and instructional texts, with the goal of facilitating student-centered instruction. In this dissertation, I offer three studies demonstrating how natural…

In 1997, developmental biologist Michael Richardson compared his research team's embryo photographs to Ernst Haeckel's 1874 embryo drawings and called Haeckel's work "noncredible". "Science" soon published "Haeckel's Embryos: Fraud Rediscovered," and Richardson's comments further reinvigorated criticism of Haeckel by…

End-Of-Chapter (EOC) problems have been part of many physics education studies. Typically, only problems "localized" as relevant to a single chapter were used. This work examines how well this type of problem represents all EOC problems and whether EOC problems found in leading textbooks have changed over the past several decades. To…

E-textbooks have generated attention in education and the expectation to use the technology has become a requirement rather than an option. The purpose of this mixed method explanatory sequential study was to explain the impact that direct instruction on comprehension strategy and e-textbook feature connection had on secondary student…

English Learners experience challenges related to comprehension of science text particularly at the high school level. The language of science differs significantly from that of conversation and expository text. Students benefit from collaborative interpretation of readings. Additionally, there appears to be a need to train adolescents in the oral…
