Growing evidence warns about the detrimental effects of the stress induced by natural disasters on learning outcomes. Yet less is known about how political leadership could mitigate the adverse exposure to these events. Exploiting a natural experiment--the massive 2010 earthquake in Chile--as an exogenous shock and using fine-grained student data,…

The COVID-19 pandemic-associated learning losses were unequal across school subjects and sociodemographic groups. This study posits that these losses are also heterogeneous based on pre-pandemic school effectiveness, that is, the value schools added above the expected students' learning based on their socioeconomic background. Using national-scale…

Constructing explanations of scientific phenomena is a high-leverage practice that promotes student understanding. In the context of this study, we acknowledge that children are used to receiving explanations from teachers. However, they are rarely encouraged to construct explanations about the causes and consequences of phenomena. We modified a…

Studies regarding school composition have been highly influential in the design of policies. However, methodological and conceptual controversies have hindered the emergence of a consensus on the existence, size, and direction of peer effects. Drawing on four cohorts of Chilean students (n = 620,044), this work analyses the extent to which the…

One of the main objectives of international large-scale assessments is to make comparisons between different countries, education policies, education systems, or subgroups. One of the main criteria for making comparisons between different groups is to ensure measurement invariance. The purpose of this study was to test the measurement invariance…

Background: Cognitive and linguistic factors have been incorporated into models to explain reading comprehension beyond classical models of reading. This study explores the contribution of executive functions, mainly domain-general and reading-specific cognitive flexibility, in reading comprehension of science texts in monolingual Spanish speaking…

Thirty-eight fourth-through sixth-grade teachers (28 female; 10 male) in urban schools in Chile were interviewed to determine how teachers' preparation to teach writing and their knowledge of how to do so acted as facilitators and/or barriers to classroom writing instruction. Teachers overwhelmingly identified their preservice preparation as a…

When in doubt, asking a peer can be very helpful. Students learn a lot of social strategies from peers. However, stated preference studies have found that for elementary school students with math questions, they prefer to ask their teacher for help. In this paper, we study revealed preferences instead of stated preferences. We analyzed the…

High-stakes testing pressures schools to raise test scores, but schools respond to pressure in different ways. Some responses produce real, broad increases in learning, but other responses can raise reported test scores without increasing learning. We estimate the effect of an accountability program on reading scores and math scores in Chile. Over…

In studies of academic resilience, the concept is typically operationalized by pre-defined cutoff values of students' achievement level and their social background. A threat to the validity of such arbitrary operationalizations is that students around the cutoff values may be misclassified. The main objective of the current study is to apply a…

Standardised International Large-Scale Assessments (ILSAs) have gained prominence in global and national educational discussions. ILSAs claim to offer valuable insights for improving education systems, but their impact on educational policy varies and has become a contested arena. This article analyses how these assessments fed educational…

Family socioeconomic status (SES) has a significant influence on children's academic success and is related to parents' attitudes toward education. Moreover, according to the expectancy-value theory, parental expectations are linked to their children's perceptions of school, which, in turn, influences the way their children invest themselves in…

Readers' theatre is a teaching strategy that consists of the interpretative reading of theatrical texts in which readers use their voices to give life to the characters. This strategy promotes the development of various skills related to fluency, among which there is prosody. This research aimed to check the efficacy of a reader's theatre program…

Although prior knowledge is an important predictor of future performance in mathematics, few studies have analyzed which areas of the subject are most critical. Most evidence is based on small- and medium-scale studies from developed countries, with results that cannot be generalized. We explore which areas of mathematics are the most important…

Introduction: Increasing evidence has shown that student mobility is negatively correlated with individual students' and schools' academic performance (Hanushek, Kain, & Rivkin, 2004; Lara, Mizala, & Repetto, 2011; Sun & Pan, 2014). However, the negative impact may be due to the switching behavior or it could be only a side effect of…
