This study examines the relationship between two secondary End of Course (EOC) exams, the Biology EOC and the English I EOC exams, and their impact on Emergent Bilingual (EB) students in a small district in South Texas. This study is a mixed methods study which uses both quantitative and qualitative data to answer three research questions: (a)…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

Science, Technology, Engineering, and Math (STEM) skills are increasingly required of students to be successful in higher education and the workforce. Therefore, modeling assessment outcomes accurately, often using more types of student data to get a complete picture of student learning, is increasingly relevant. The Program for International…

Although Christians comprise the majority of the population in the United States, they make up less than one third of the scientific community. This underrepresentation is attributed to the desire to avoid the secular culture in academia or self-selection due to a perceived incompatibility or belief in negative stereotypes of Christian scientists.…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

The purpose of this research was to explore the coherence and effectiveness of an assessment approach that combined principles of cognitive-based assessment, performance assessment, and the Next Generation Science Standards. By drawing on research on learning progressions and cognition in geoscience to design, implement, and analyze an Earth…

Over the past few decades, physics education researchers (PER) developed a variety of assessments instrument for research and instructional purposes. Most of these instruments are designed to measure topical understanding. Generally, if student performance is satisfactory, it is assumed that the students possess the content understanding and that…

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 three articles in this dissertation explore how curriculum, instruction, and assessments should align with the vision for science learning outlined in the Framework for K-12 Science Education. Together, the papers demonstrate how curriculum, instruction, and assessment, when mutually supportive of each other, can foster a learning environment…

Cognitive scientists and psychology researchers have given growing attention to evidence of the testing effect, that is, the improvement of students' recall through memory-retrieval practice in the form of quizzes and exams. While laboratory experiments consistently show dramatic positive effects on learning through the testing effect,…

It was unknown the impact a middle-level agriscience program had on the eighth-grade general science course. This quantitative study was designed to investigate the relationship between student performance on agriscience state assessments and the state DeSSA Science test. It was also unknown the relationship between eighth-grade agriscience and…

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…

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…

Public schools in the state of Texas are required by the Texas Education Agency to administer five state exams to high school students consisting of Algebra I, Biology, English I, English II, and U.S. History. These exams play a big role in school accountability and in high school graduation. For this reason, many schools develop intervention…

This dissertation investigates the impact of attending a STEM-designated elementary school on students' math, ELA (English Language Arts), and science achievement and growth scores. As technology continues to advance in education, educators are exploring innovative instructional methods. With a concerning decline in math proficiency nationwide,…
