The issue of students' difficulties in processing operations with percentages has been addressed in several international research studies from a qualitative perspective. In this study, we analyze students' difficulties on this topic, focusing on the transition from middle school to high school with a mixed methods research design. We focus on…

Montessori is a highly individualized pedagogy that prioritizes following each child's individual interests over standardized test scores. This quasi-experimental study compares groups of Montessori students (treatment groups, N = 535-710) with control groups of non-Montessori students, matched through the simple matching method, which controls…

We study a decade of achievement gaps for fifth-, eighth-, and 10th-grade students in Norway using administrative population data. Norway is a wealthy and egalitarian country with a homogeneous educational system, yet achievement gaps between students at the 90th and 10th percentiles of parental income and between students whose parents have at…

National and international large-scale assessments of mathematics show that, in most nations, males achieve better results than females and Italy is one of the countries with a greater gap. Many research studies in mathematics education have analysed this issue, using both quantitative and qualitative methods to understand the sources and…

How does the act of explaining influence learning? Prior work has studied effects of explaining through a predominantly proximal lens, measuring short-term outcomes or manipulations within lab settings. Here, we ask whether the benefits of explaining extend to academic performance over time. Specifically, does the quality and frequency of student…

In the frame of national Italian standardized assessments in mathematics, a didactic phenomenon has been observed concerning students' behaviour when answering an item: students are inclined towards not accepting an output which is not clearly recognizable with something distinct from the starting inputs. The observed effect seems to originate…

This study estimates the causal impact of 8th grade English learner (EL) reclassification on high school English language arts (ELA) standardized test scores, SAT (Scholastic Aptitude Test) reading, and on-track to graduate status. I apply a regression discontinuity design to rich administrative data from a large district in California. The…

Ideologies regarding what is "good" teaching undergird common teaching practices and pedagogical decisions, which may support and/or run counter to the broader policy environment in which they occur (Gibson, 1998). Drawing from a six-month ethnography of 10th-grade newcomer students from Mexico and their teachers in a Central Texas…

Previous research has shown that adolescent peer groups play a role in maintaining and exacerbating demographic differences in achievement. However, there is still limited knowledge about the malleable factors that contribute to these achievement disparities. This short-term longitudinal study examined one such malleable factor--namely, perceived…

New Mexico is one of 48 states that offer a biliteracy seal to high school graduates to recognize their proficiency in a non -English language. The Regional Educational Laboratory Southwest English Learners Research Partnership collaborated with a large urban district in New Mexico to study the characteristics and college readiness of students who…

The full study to these appendixes examined who earns biliteracy seals in a large urban district in New Mexico and how they impact college outcomes. The study used data from three cohorts of grade 12 students in the district from 2017/18 to 2019/20. The New Mexico Public Education Department and district leaders can use the findings to decide how…

Purpose: The purpose of this two-year study was to assess the impact of the CORE program, a model that integrates technology and active learning modules in high schools by providing multi-disciplinary teams of teachers and administrators with professional development and resources to support the development of students' non-cognitive skills and…

Disrupted schooling can heavily impact the amount of education pupils receive. Starting in early June of 2011 a huge social outburst of pupil protests, walk-outs, riots and school occupations called the Chilean Winter caused more than 8 million of lost school days. Within a matter of days, riots reached the national level with hundreds of…

The United States and the United Kingdom have used standardized high-stakes testing as a measurement of students' cognitive level to determine success in the 21st century. Standardized tests have given teachers guidance to help them determine what to teach students and how to teach to the test. With such increased emphasis on high-stakes…

Using data from the nationally representative Education Longitudinal Study of 2002, this study examined how journalism participation in high school relates to subsequent academic outcomes. The analysis statistically controlled for a host of correlates of academic achievement, isolating the associations between journalism participation and…
