The advantages and disadvantages of ability grouping for student achievement are strongly contested, with studies presenting different results. However, much of this research has focused on class-level or subject-level ability grouping. Relatively less research has focused on school-level ability grouping. More importantly, the role of teacher…

Curriculum reforms often fail because teachers are asked to implement approaches to teaching and learning that are contrary to their beliefs about students and how to teach them. Since curriculum reforms are attempts to resolve particular educational problems, failures in implementation produce parallel failures to resolve the problem for which…

Background: Over the past several decades, understandings of civic knowledge and engagement have been enlarged in productive ways; the field has been transformed by contributions rooted in and showcasing critical, cultural, transnational, activist, and participatory approaches to the civic. Civic action research fits neatly amid these new…

In this study, a paper folding activity task, which involved reaching the Pythagorean Theorem with a series of steps was designed. The aim of the task is to reach the Pythagorean Theorem with folding activities by deductive reasoning and logical inference. The study aimed to examine the effectiveness of the task and to share the patty paper…

"Lesson study" has garnered considerable attention from educational researchers and practitioners as a promising method for improving instruction. At its core, lesson study reflects a collaborative inquiry process, grounded in cycles of planning, enacting, and reflecting, that promotes teacher learning through active engagement in lesson…

This dissertation investigates the challenge of translating theoretical knowledge into practical application regarding collaborative practices in secondary schools, specifically focusing on principals' leadership roles. Conducted in accredited middle and high schools in South Carolina's Lowcountry region during the 2023-2024 academic year, the…

Researchers in science education lacks valid and reliable instruments to assess students' "disciplinary" and "epistemic" reading of scientific texts. The main purpose of this study was to develop and validate a Reading in Science Holistic Assessment (RISHA) to assess students' holistic reading of scientific texts. RISHA…

There are many taxonomies in education related to the cognitive learning domain. This study aimed to analyze the learning outcomes in the 9th and 10th grade 2018 geography curriculum according to Webb's depth of knowledge. Document analysis was used in the study. The geography curriculum was analyzed by considering the four levels of Webb's depth…

Using LatCrit and QuantCrit, we examined the effect of school climate, ethnic identity, and self-esteem on GPA in a sample of 300 Latinx high school students. We found significant positive correlations between climate and GPA as well as self-esteem and GPA. Moreover, using structural equation modeling, we found self-esteem mediated the…

America's schools are more diverse than ever, but the teachers are still mostly White. Overwhelmingly, the research says that Teachers of Color in classrooms provide numerous benefits for all students (e.g., Ahmad & Boser, 2014; Archinstein et al., 2010; Cherng & Halpin, 2016; Partelow et al., 2017; Perlman et., 2016; Villegas & Lucas,…

This project creates the first educational pipeline for the state of Texas. It incorporates middle school as a key transition point, differentiates between advanced degree achievement among Latinas/os and Chicanas/os, and fashions a secondary pipeline with a narrower age range. Findings indicate that the move from eighth grade to ninth is a…

Gaming the system, a behavior in which learners exploit a system's properties to make progress while avoiding learning, has frequently been shown to be associated with lower learning. However, when we applied a previously validated gaming detector across conditions in experiments with an algebra tutor, the detected gaming was not associated with…

Although race discourse has become increasingly encouraged to address educational inequities, racialized speakers are often expected to accommodate white listening subjects in institutional settings. Building upon multidisciplinary scholarship of race and language, I develop place-based raciolinguistics as an explanatory theory and linguistic…

Social cognitive career theory (SCCT) and the theories of reasoned action and planned behaviour (TRAPB) have both guided studies seeking to explain students' intentions and decisions related to future science engagement. The purpose of this study was to simultaneously validate measures for these two social psychological models and closely examine…

We report on an innovative design of algorithmic analysis that supports automatic online assessment of students' exploration of geometry propositions in a dynamic geometry environment. We hypothesized that difficulties with and misuse of terms or logic in conjectures are rooted in the early exploration stages of inquiry. We developed a generic…
