This study examines the impact of hands-on chemistry laboratories in shaping secondary students' chemistry self-concepts. Utilizing a mixed methods approach, the research sought to address how students' chemistry self-concept varied during the first semester of an introductory chemistry course and give voice to students' understanding of the role…

This study aims to discover the existing experiences that lead to local rural knowledge (LRK) of specific rural Northeast Nebraska communities. This information will assist in understanding the impact that LRK has on young children's science knowledge in rural communities. By engaging in hands-on experiences and interactions, science learning…

Marine communities are experiencing rapid environmental changes including warming temperatures and ocean acidification (OA). For organisms within these communities, responses to ocean change are shaped by population- and community-level interactions which may modify their responses. This dissertation integrates experimental, field, and modeling…

Non-formal STEM education programs can expose youth to STEM concepts outside the formal school environment. These programs employ education techniques such as hands-on learning, problem-solving, and connection to authentic science experiences. Youth participating in non-formal STEM programs are more likely to consider themselves science people and…

Natural disasters such as Hurricane Harvey, which hit the Gulf Coast region of Texas on August 25, 2017, may have potentially devastating effects on the local community and especially the public education system. Adverse health consequences because of this traumatic event may include Compassion Fatigue, a condition of emotional, physical, and…

Despite an extensive amount of research examining students' perceptions of alternative laboratory experiences, little focus has been aimed at the perceptions of adult learners. This two-phase mixed-methods study investigated the preferred at-home laboratory experience, and the factors that played a significant role in the user experiences, of…

Chemistry is considered a difficult subject by most students. Its difficulty lies in Chemistry's complex and abstract nature. This highly abstract nature requires constant interplay and coordination between the macroscopic, particulate, and symbolic representations. Experts can successfully navigate the various representations without overloading…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

This qualitative research project investigated high school students' experiences with science, as well as how their unique experiences can be used to develop empowering science education for all students. Inquiry was conducted via the photovoice method with a critical sociocultural theoretical framework. Results showed that students' science…

This series of articles were developed to understand how blind and low vision students engage in Science, Technology, Engineering, and Mathematics (STEM) and their considerations in pursing STEM education and careers. Multiple methods were used to investigate the overarching topics such as substantive grounded theory and the examination of photos…

The concept of inclusive education stressed the classroom conditions for students with disabilities (SWDs) as they strive to achieve their maximum learning potential alongside their nondisabled peers. The feat proved to be challenging as teachers implement instructions that meet federal laws, district guidelines and policies, schools' visions, and…

Many high school science teachers feel ill-equipped and ill-trained to adequately support the ever-increasing number of ESL/EFL students. The purpose of this qualitative single case study was to explore science teachers' perspectives of effective science teaching strategies, the challenges implementing science teaching strategies, and suggestions…

This dissertation examines, in three studies, undergraduate student experiences in social aspects of online learning when conducting remote physics laboratories. The first quantitative, observational study examined introductory students' epistemological, socialization, and help seeking views (N=998). Parametric and nonparametric tests indicated no…

It is often claimed that engineering projects improve student achievement in mathematics and science, but research on this topic has shown that many projects do not live up to the claim (Teacher Advisory Council, 2009). Ideally, undertaking a science project should be motivating, while also helping students to understand the interplay between…

My dissertation is a pre-mid-post-test, quantitative research design, including surveys and written assessments, to answer these research questions: 1. How do students' science mindset vary over time when engaged in science inquiry activities? Is there a difference between male and female students? 2. Is there a relationship between 7th grade…
