In this study, we investigated how secondary students interpret algebraic expressions that contain literal symbols to stand for variables. We hypothesized that the natural number bias (i.e., the tendency to over-rely on knowledge and experiences based on natural numbers) would affect students to think that the literal symbols stand for natural…

Urban school districts have seen low scores on NWEA Map math scores (Education Recovery Scoreboard, 2024). To foster and promote urban youths' capabilities to learn mathematics, a new method to teach, enhance, and remediate understanding of fractions was developed, Fractions and Signed Numbers Workshop (FracSi). It utilizes the approach of an…

Inspired by a "whole child" framing, the current study takes a "whole classroom" perspective to consider classroom practice. Study aims included: (1) presenting a systematic video-based observational coding strategy to concurrently consider practice domains that have implications for learning--cognitive instruction, classroom…

The COVID-19 pandemic profoundly impacted the methods of instruction for K12 and higher education institutions around the world. Schools and families were challenged to adapt to online-based modes of instruction with minimal preparation. This study examined the importance of the learning environment and commitment to assignments as predictors of…

Transportation is one of many potential obstacles that students might face as they attempt to attend school, but there are few opportunities to identify the unique contribution of transportation to school attendance. We apply models of commuting stress developed for adult commuters to students in an open enrollment school district to examine…

This study explores how public-school teachers who host student teachers in urban, grade 7-12 classrooms (referred to as cooperating teachers or classroom mentors in this study) define their role in preparing pre-service teachers. This study is particularly interested in yielding insight into how participants describe the "practice" of…

Positive perceptions of school climate correlate with many dimensions of academic well-being and student health. Unfortunately, some existing research finds more favorable perceptions in middle school for general education students (GENs) than for students with disabilities (SWDs). Given the importance of ninth grade to student success, it is…

Students with disabilities are entitled to attend a school of their choice. In order for the rights of students with disabilities to be honored during the high school choice process, principals must create school structures and systems that are alignment to federal policies to lead in the best interest of students. This mixed methods, qualitative…

We study the distributional effects of remote learning using a novel approach that combines preference data from a conjoint survey experiment with administrative records of student outcomes. The experimentally derived preference data allow us to account for selection into remote learning while also studying selection patterns and treatment effect…

Objectives: At the K-12 level, "CS for All" initiatives across the country strive to increase equitable access to and participation in computer science (CS). However, there are many open questions about the implementation and effectiveness of these initiatives, including the extent to which exposing young people to CS early on can shape…

Scaffolding ensures multilingual learners (ML) are adequately challenged and supported at school while learning English and subject area content. Due to the dynamic nature of language development, teachers may struggle to anticipate how to adequately scaffold lessons or reflect on their practice to identify areas for improvement. This paper…

Early adolescence is a time of rapid cognitive, psychosocial, and physical development, and an array of contextual factors, such as systemic racism, exert significant influence. Universal behavioral health screening data of 4,234 middle school students were examined to explore the influence of demographic (e.g. ethnicity, race) and contextual…

This study explores the association between school-level poverty rates and young peoples' perceptions of student empowerment, drawing on survey and administrative data from a large urban district. Participants included 29,318 diverse youth in grades 6-12 from 211 schools. We used multilevel linear regression models to estimate the relationships…

In this study with 153 middle school students, we investigate the influence of the number of decimal places from the reading of a measurement device on students' decisions to change or keep an initial hypothesis about falling objects. Participants were divided into three groups, introduced to two experiments--the time it takes a free falling…

The COVID-19 pandemic has impacted society in different areas. In education, several reports show the deleterious effects of the disease on the physical and mental health of students, family members, and teachers around the world. Also, in Brazil, affect studies indicate the prevalence of anxiety, stress, and depression among students. The present…
