We examine the fundamental and complex role that time plays in the learning process. We begin by developing a conceptual framework to elucidate the multiple obstacles schools face in converting total time in school into active learning time. We then synthesize the causal research and document a clear positive effect of additional time on student…

This paper presents and assesses the effects of an Extended School Time project (ESTp), with a working day of 8 contact hours, that aimed to develop the students as a whole in its academic, artistic, sport, social and human dimensions. Based in active and integrated pedagogical practices, the project promoted the integration of knowledges,…

The current study evaluates effects of teaching factors and extended day programs regarding both average achievement and socioeconomic achievement gaps. Analyses are based on data from the National Educational Panel Study in Germany. The sample comprises 1523 students in 120 classes in 71 secondary schools. The investigation period covers fifth…

Schools often have to decide between extending the length of the school year or the school day. This paper examines the effects of changes in the distribution of instructional time on eighth-grade student achievement through a methodological framework that disaggregates total yearly instructional time into separate inputs for days per year and…

Expanded Learning Time (ELT) measures have been implemented internationally to reduce the likelihood of academic underachievement among students at risk. The goal of this article is to examine the components of an ELT initiative aimed at supporting students at risk of academic failure in order to optimize the components that can improve its use…

This paper evaluates the impact of extension of the school day in the context of Brazil's "Mais Educação" Extended School Day Program. Using school level longitudinal data, we find that the program reduces the dropout rates of students in all grade levels, raises the enrollment of students in grades 6-9, but reduces the enrollment of…

Academic achievement in the nation's lowest performing schools is troubling. Despite improvements in students' overall academic achievement over the past few decades, proficiency gaps in reading and mathematics remain across income, racial, and ethnic groups. One promising strategy for reducing achievement gaps is to expand the school day, often…

In 2012, things were not looking good for Grant Beacon Middle School in Denver, Colorado. Enrollment numbers were declining, students were not reaching required academic levels, and the Denver Public Schools district designated the school as on watch. By implementing a plan that emphasized expanded learning opportunities--adding five hours to the…

In schools across the country, educators recognize the power of the arts to change young lives. They know that students' sustained engagement with enriching, high-quality experiences in the arts promotes essential skills and perspectives--like the capacity to solve problems, express ideas, harness and hone creativity, and persevere toward a job…

Expanded learning time (ELT) is a practice that entails increasing the length of the school day for all students, with the goal of improving student outcomes, especially in low-performing schools. Boston Public Schools (BPS) has been implementing ELT as an improvement strategy in low-performing schools since 2006. In 2015 the district drastically…

Instructional time is a fundamental educational input, yet we have little causal evidence about the effect of longer school days on student achievement. This paper uses a sharp regression discontinuity design to estimate the effects of lengthening the school day for low-performing schools in Florida by exploiting an administrative cutoff for…

The vast majority of American students are neither prepared nor sufficiently engaged to become science, technology, engineering, and mathematics (STEM)-literate citizens or innovative STEM professionals (National Research Council, 2007; Carnegie Corporation and the Institute for Advanced Study, 2009; National Science Board [NSB], 2010; President's…

Eric Schwarz cofounded Citizen Schools in 1995 to offer Boston students living in low-income communities the opportunity to participate in apprenticeships in a variety of careers. Twenty years later, Citizen Schools has served more than 50,000 mostly middle-school students in seven states coast-to-coast, engaging some 40,000 volunteer…

Expanded Learning Time (ELT) is seen as one promising approach for improving academic achievement, particularly in the nation's chronically low-performing schools. Since 1995, Citizen Schools (CS) has developed and supported the implementation of its own ELT model. The CS ELT model uses an additional shift of educators and community volunteers to…

In Chicago, over a quarter of students fail at least one semester of algebra in their ninth grade year, and only 13% of students who fail both semesters of Algebra I in ninth grade graduate in 4 years. Offering credit recovery options is one strategy to deal with high failure rates. The primary goal of credit recovery programs is to give students…
