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…

Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

The aim of this study was to identify students' motivational beliefs in science and revealed the connections between the profiles and three cognitive dimensions of science achievement through the examination of the socio-economic status (SES) and gender covariates of the profile memberships. Latent profile analysis using science motivational…

The jigsaw model is a dynamic cooperative learning approach where students become experts on different segments of the material and teach their peers, thereby enhancing engagement accountability, team work, and ultimately improving academic achievement. This study investigated the effectiveness of a cooperative learning strategy on secondary…

The study was conducted to ascertain if learning styles and corresponding teaching methods are factors that influence effective learning. The study employed a non-equivalent planned variation quasi-experimental design. The study's sample comprised 362 chemistry students from six senior high schools in Delta State. The students were selected using…

This study investigates the impact of constructivist teaching methods on achievement and misconceptions in mechanics, with a focus on gender differences. The research involved 88 first-year physics students enrolled in the physics teacher training program. Using a quasi-experimental design, students were divided into experimental (constructivist…

This paper deals with the science competences of fifth-grade students (ages 10 and 11 years) in Slovenia. The science content researched in this study comprises chemical concepts, such as aqueous solutions, states of matter, and nutrition. The science competence and science competencies that elementary school students are supposed to develop are…

Noticing the inconsistency in previous studies of gender differences in learning physics, it was determined to check whether a gender gap exists in a relatively large sample of competitors (N = 12,966) from Serbia. The aim of the research presented here was to analyze the achievements of male and female lower secondary school students, competitors…

The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…

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…

Metacognition and curiosity play an important role in the educational process. Therefore, it is significant to examine their correlation with students' performance and satisfaction with classes. In order to examine whether the effect of metacognition and curiosity on physics performance and satisfaction with physics classes depends on gender, a…

Globally, the private school share of enrollment increased from about 14 percent in 2000 to about 18 percent in 2019. We estimate the systemic effect of private enrollment share on learning outcomes. Estimates of the systemic effect of private school enrollment capture any competitive effects as well as any differences between public and private…

The study investigated the impact of guided inquiry-based laboratory experiments enriched instructional (GIBLEI) approach on conceptual understanding of tenth grade students in biology. The study included two purposively chosen schools and used a quasi-experimental design with non-equivalent groups. A class was randomly assigned as 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…

This dissertation investigates how the numerical representation of women in small collaborative groups influences their learning in a college biology class for non-majors focused on sex, gender, and society. Prior to the start of the semester, the researchers divided students into all-male, all-female, or mixed-gender groups of varying sex ratios.…
