Retrieval practice has generally been shown to be an effective study strategy. The benefits of retrieval practice, however, have largely been compared to restudying, a passive and ineffective study strategy. Here, I investigated the memory and metamemory effects of practicing retrieval versus generating mnemonics, an active and effective study…

The primary purpose of this study was to compare academic variables from students participating in mixed teaching methods/course revitalization biology courses to those in traditional courses at two community colleges in Tennessee. A two-group comparison design using archived data was used, which evaluated differences in final grades, exam scores,…

Organic chemistry is a class well known to be difficult and necessary for many careers in the sciences, and as a result, has garnered interest in researching ways to improve student learning and comprehension. One potential way involves using eye tracking techniques to understand how students visually examine questions. Organic chemistry involves…

The COVID-19 pandemic affected education, causing schools in the United States to switch from face-to-face to remote learning modalities. The purpose of this study was to examine the impact of educational modalities on academic achievement in K-12 education to contribute to evidence-based decision-making in science education by practitioners and…

Michael Simonson's equivalency theory provided support for this study. Simonson's equivalency theory is built around the idea that while there should be different learning experiences for online and seated students, those learning experiences should be equivalent. Equivalency theory includes equivalency, learning experiences, appropriate…

I conducted a set of four studies to catalogue and examine course elements, including active learning strategies and evidence-based teaching practices, and their influence on student experiences and performance in college biology classes. In the first study, I defined the term "active learning" and catalogued the 300[plus] strategies…

The purpose of this quantitative study was to explore the effect of Project Lead the Way(TM) Engineering Curriculum on the academic performance of Grades 9-12 students in a Southwest Texas school district. Study participants were comprised of 9-12 graders who participated in Advanced Placement (AP) Testing in a large Southeast Texas school…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

The purpose of this study was to analyze the effectiveness of scripted biology curriculum as a means of providing students with the information required to increase content knowledge, while comparing curriculum developed by the teacher that utilizes the Understanding by Design (UbD) framework (2005). The study is guided by two research questions:…

The purpose of this causal comparative study was to test the theory of assessment that relates benchmark assessments to the Georgia middle grades science Criterion Referenced Competency Test (CRCT) percentages, controlling for schools who do not administer benchmark assessments versus schools who do administer benchmark assessments for all middle…

The Next Generation Science Standards (NGSS) call upon K-12 science teachers to provide authentic science and engineering practices which deepen understanding of core ideas and crosscutting concepts (NGSS Lead States, 2013). Probeware technology provides exposure to these scientific practices; however, there is a disconnect between the frequency…

The purpose of this study was to provide quantitative data about the effectiveness of the traditional lecture method of teaching in a college science course in contrast with an interactive case study method of teaching and learning. The study investigated one professor's teaching an Advanced Human Anatomy and Physiology course at Nebraska Wesleyan…

This quantitative study examined levels of achievement in learning outcomes when using a face-to-face dissection lab compared to an online dissection lab. Constructivist theory and Understanding by Design learning framework were at the core of this research study design. Data was collected from 24 health science students at a private Midwestern…

This study examined the effects of cooperative testing versus traditional or individual testing and the impacts on academic achievement, motivation toward science, and study time for 9th grade biology students. Research questions centered on weekly quizzes given in a flipped classroom format for a period of 13 weeks. The study used a mixed methods…

This research investigates students' learning about the electron transport chain (ETC) process in photosynthesis by watching a video followed by playing a serious board game-Electron Chute- that models the ETC process. To accomplish this goal, several learning outcomes regarding the misconceptions students' hold about photosynthesis and the ETC…
