Women, especially Black and Latina women, are marginalized in physics, including in high school classrooms. Recognition is one of the ways women and girls experience marginalization in physics. This dissertation is comprised of three distinct but related studies examining how students experience recognition in an AP Physics 1 classroom. The first…

This study explored the effects of explicit and implicit epistemologically enhanced instructions probing 9th-grade students' personal epistemologies on their physics-related personal epistemology (PPE) and physics achievement in the heat and temperature unit. In the implicit epistemologically enhanced instruction (IEEI), different dimensions of…

The purpose of this study was to examine the impact of student perceptions of the classroom motivational climate on engagement and academic achievement in secondary STEM courses. Additionally, the mediating effect of students' ease of the course perceptions on the relationship between engagement and academic achievement was assessed. By better…

Students enter university programs with the hope of passing courses and eventually graduating with a degree. However, many students experience challenges transitioning into their program and the first year. Some of these challenges may be influenced by their pre-collegiate experiences, as certain students come from under-resourced communities…

Little is known about the motivational factors or design features that might lead female career and technical education (CTE) health sciences students to persist in self-regulated engagement to win state achievement in serious simulation games (SSGs). In this study, 12th grade female CTE health sciences students played a 3-Level hand hygiene SSG…

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…

The Black student population underperforms all other demographic groups in high school science achievement. The purpose of this quantitative correlational research was to examine various factors influencing the science proficiency of Black students in selected Florida high schools. Florida's PK--20 Education Information Portal provided the…

This study integrated environmental issues as the initial problem to explore the process of problem-solving of high school students and proposes the concept of environmental problem-solving (EPS) to probe the interaction between high school students' scientific performance and EPS strategies. There were 139 high school students in Taiwan who…

Assessing scientific modeling competence (SMC) is challenging because of the multi-dimensionality of the construct and the potential variability of student performance across tasks. To deal with the challenges, this study applied Kane's validity framework to assess high-school students' SMC in Newtonian mechanics and examined how students'…

The question of precollege physics access and performance has been a persistent concern when considering the goal of diversifying participation in post-secondary STEM study and careers. This observational study examined school-level academic and demographic predictors of high school physics enrollment and performance in the USA. Due to the…

This study aims to investigate the impact of using the flipped classroom strategy on motivation and academic achievement in learning science among 9th-grade students Proved as an innovative technique, flipped learning improves academic performance, enhances students' motivation, supports independent learning, triggers higher thinking skills, and…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

Good metacognitive allows individuals to more easily adapt to changes in the learning environment and face challenges that arise. They tend to be more flexible in changing their learning strategies according to new needs and situations. The aim of this research is to determine the correlation between metacognitive and the academic resilience of…

Student perceptions toward homework assigned in general chemistry courses was investigated in this study. The study participants were required to complete homework assignments using two different online systems, ALEKS (adaptive-responsive system) and Sapling (traditional-responsive system). An online survey investigating their general perceptions…

The aim of this study is to develop a valid and reliable achievement test on the subject of 'Basic Compounds in the Structure of Living Things'. During the preparation of the draft form of the test, a 32 item-question pool was created by the researchers in the light of the relevant literature. Then, these questions were presented to expert opinion…
