Evolution is a key feature of undergraduate biology education: the American Association for the Advancement of Science (AAAS) has identified evolution as one of the five core concepts of biology, and it is relevant to a wide array of biology-related careers. If biology instructors want students to use evolution to address scientific challenges…

The United States lags behind other countries in science literacy at the 4th, 8th, and 12th grade levels. Subsequently, this is seen at the higher education level, especially with gateway science courses. BIO 103-General Biology I is a gateway course at Lion University. Passing this course is crucial for students to progress in several science…

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,…

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote…

Context is the background or the settings of an event or idea. It is only when events or ideas are considered within the context in which they occur that they can be fully understood. In education, the application of knowledge communicated in one context to a different one is a central feature of learning. However, knowledge transfer can be…

Educators have been leaving the field of education at a high rate each year with no signs of slowing down. Tennessee, as well as many other states across the country, have started the school year with unfilled positions due to so many vacancies. Previous researchers found educators left due to an overwhelming workload paired with an escalation in…

This dissertation aimed to advance the field of biology education in several ways. First, we aimed to demonstrate if, and to what extent, student-generated conceptual models can be used on summative assessments to accurately assess student understanding of gene expression. Next, we described patterns of changes students make to conceptual models…

Digital educational games have been a part of the educational landscape since the early 1970s. Since then, there has been a proliferation in the quantity, format, type, and quality of digital educational games available to classroom teachers. Despite this, the body of literature surrounding the effectiveness of these digital educational games…

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…

Students diagnosed with sickle cell disease (SCD) are eligible for special education services and benefit from advances in medical research that have extended the life expectancy of this population; however, there is a dearth of research on medical professionals' and PK-12 educators' awareness epistemological beliefs about pediatric sickle cell…

One of the goals of science education is to help students make sense of the world around them. To that end, it is critical that students understand the central ideas in each discipline like, in chemistry, energy and interactions. These ideas are of particular importance because they are directly related to one another and are relevant across other…

A novel intervention to introduce undergraduate students to bioinformatics, provide authentic research opportunities, and support student retention in science majors and careers is presented in the Characterizing Our DNA Exceptions (CODE) project. The need to increase the number of qualified STEM graduates, particularly in the fields of…

The gender gap in science education has been a persistent topic of research and initiatives designed to narrow the gap have been successful within specific domains. However, although the gender gap is continuing to decrease, equity and equal representation are still lacking in some domains. Self-efficacy levels, interest levels, attitudes, and…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

Science classrooms continue to privilege narrow conceptions of science, and students of color are frequently identified by teachers as disengaged or uninterested in science--part of a deficit narrative socially constructed over time. In this design-based research study, I explored the development and implementation of culturally relevant and…
