Las Americas Middle School is a newcomer program within Houston Independent School District (HISD) that serves students in Grades 4 through 8 who have been in the U.S. for less than one year. As a non-zoned school of choice, Las Americas has no attendance boundary, meaning that students and families must opt to enroll in the school. This brief…

A Concept-Based Curriculum is designed to help students uncover important, transferable understandings about what it means to be a capable reader, writer, speaker, viewer, listener, and thinker. But, too often, a well-designed, conceptual curriculum does not translate into conceptual teaching. "Concept Based Literacy Lessons" helps…

Previous research has not adequately explored students' behavioral processes when addressing computational thinking (CT) problems of varying difficulty, limiting insights into students' detailed CT development characteristics. This study seeks to fill this gap by employing gamified CT items across multiple difficulty levels to calculate…

Most students with reading difficulties struggle to read words. We examined intervention effects for students with "significant" word reading difficulties (SWRD; standard score of 80 on at least one pretest measure of word reading), which includes individuals with or at risk for dyslexia. We investigated: (a) What are the effects of…

The impact of the International Baccalaureate (IB) curriculum on Chinese teachers' self-efficacy has been unknown. The purpose of this causal-comparative study was to determine the impacts of the International Baccalaureate curriculum on Chinese teachers' reports of self-efficacy. Two groups were studied, the first comprised Chinese public…

Gender differences in math-related professional achievements have been identified as a worldwide problem. Academic achievement assessments, however, have repeatedly revealed gender similarities. The observed gender similarity might be due to biased assessments that heavily rely on reading skills, which favors girls. The current study analyzed 29…

We examined the development of numerical magnitude representations of fractions and decimals from fourth to 12th grade. In Experiment 1, we assessed the rational number magnitude knowledge of 200 Chinese fourth, fifth, sixth, eighth, and 12th graders (92 girls and 108 boys) by presenting fraction and decimal magnitude comparison tasks as well as…

The COVID-19 pandemic resulted in an unanticipated, near-universal shift from in-person to virtual instruction in the spring of 2020. During the 2020-21 school year, schools began to reopen, and families were faced with decisions regarding the instructional mode for their children. We leverage administrative, survey, and virtual-learning data to…

For the effective expression of feelings and thoughts, handwriting should be produced fluently at a certain speed. The aim of this study was to examine the development of handwriting speeds in 4th-8th grade primary and secondary school students in terms of some variables. In line with this aim, answers were sought to the question, "Do 4th-8th…

This study re-envisions the Nation's Report Card from a "whole child" perspective that considers not just students' academic achievement, but also their physical and mental health. Jaekyung Lee's integrated analysis of the National Assessment of Educational Progress and the National Survey of Children's Health datasets reveals that many…

In 2017, the mathematics assessments that are part of the National Assessment of Educational Progress (NAEP) program underwent a transformation shifting the administration from paper-and-pencil formats to digitally-based assessments (DBA). This shift introduced new interactive item types that bring rich process data and tremendous opportunities to…

In this study, we explored the gender differences in science achievement, interest, creativity, and so on, using a national representative sample from the National Assessment of Education Quality (NAEQ). NAEQ assessed the Grade-4 (n = 112,314) and Grade-8 (n = 74,808) students' scientific literacy of Mainland China in 2017. The findings indicated…

We used the Stanford education data archive (SEDA) data to examine the heterogeneity among urban school districts in the United States. The SEDA 2.1 includes data sets on students' mathematics (Math) and English language arts (ELA) achievement from 2008 to 2014 at the district level. Growth mixture modeling was used to uncover the underlying…

This study evaluated the forecasting accuracy of trend estimation methods applied to time-series data from computer adaptive tests (CATs). Data were collected roughly once a month over the course of a school year. We evaluated the forecasting accuracy of two regression-based growth estimation methods (ordinary least squares and Theil-Sen). The…

Numerous studies have investigated the relationship between the home literacy environment and reading motivation; however, their results are inconsistent. Limitations to previous studies include relying on parents' input concerning students' reading motivation, looking at only a few components of reading motivation, and focusing primarily on the…
