Building on earlier work that explored within-student variation in hours of instruction across school subjects, we investigate the impact of instruction time on student test scores in Switzerland, as measured by the PISA 2009 test. Our results confirm the results of previous studies of a positive effect of instruction time on student performance.…

Teaching foreign languages has become a major goal for many education systems around the world. In today's increasingly interconnected world, speaking multiple languages improves employability, fosters respect for people from other cultures, and gives young people direct access to content that would otherwise be inaccessible, including literature,…

The Council of the European Union has set the goal of reducing low achievement in reading, mathematics and science among 15-year-olds to less than 15 % by 2020. How are European countries going to achieve this? One of the key elements in the learning process is the instruction time available to students. In fact, not only the quality of…

Highschool homework as an integral part of the study skills benefits students' learning outcomes significantly. Consistency of completing homework contributes to rising scores in any given assignment such as quizzes, regular tests, standardized tests, etc. The purpose of homework aims at different targets and it is designed for specific groups and…

This report examines the recommended minimum instruction time in full-time compulsory general education in 2016/17 in 42 European education systems. It includes national diagrams illustrating the data by country and by subject. The comparative overview examines the policy changes that have taken place over the last year regarding the recommended…

Educational reformers use international evidence to argue that increasing the number of days in school and the length of the school day will improve academic achievement. However, the international data used to support these claims (1999 Third International Math and Science Survey and 2000 Program for International Student Assessment) show no…

There is no real consensus on how much class time is enough when it comes to learning mathematics, science and reading. But educators and policy makers generally agree that while it's important for students to spend considerable time in school lessons to acquire new skills, spending more hours and minutes in class is not enough to ensure that…

At a time when the Organisation for Economic Cooperation and Development (OECD) and partner countries are trying to figure out how to reduce burgeoning debt and make the most of shrinking public budgets, spending on education is an obvious target for scrutiny. Education officials, teachers, policy makers, parents and students struggle to determine…

This study explored the relationships among high school students' reading comprehension achievement, three latent constructs (reading comprehension strategy use, reading comprehension strategy instruction, reading attitudes), and five control variables (gender, minority status, socio-economic status [SES], class time, class size). The purpose of…

Despite decades of educational reforms, the achievement gap based on socioeconomic status (SES) persists in the United States. Not only does the SES-based achievement gap persist, it has also been widening. This study focused on the role of students, hypothesizing that students might reduce the SES-based achievement gap by increasing their…

Attracting significant attention from the media and policymakers, international student assessments are serving as pressures on and challenges for individual countries. Even so, paying attention only to publicly released rankings in international student assessments may lead to superficial interpretations of the assessment results. Simply equating…

The OECD Programme for International Student Assessment (PISA) examines not just what students know in science, reading and mathematics, but what they can do with what they know. This report is the product of a collaborative effort between the countries participating in PISA, the national and international experts and institutions working within…

Drawing from two international measures, Trends in International Mathematics and Science Studies (TIMSS) and Program for International Student Assessment (PISA), this brief provides a snapshot comparison of the United States to other education systems. Specifically, this brief addresses how the U.S. compares to other countries in overall…

There are large differences across countries in instructional time in public schooling institutions. For example, among European countries such as Belgium, France and Greece, pupils aged 15 have an average of over a thousand hours per year of total compulsory classroom instruction while in England, Luxembourg and Sweden the average is only 750…

There are large differences across countries in instructional time in schooling institutions. Can these differences explain some of the differences across countries in pupils' achievements in different subjects? While research in recent years provides convincing evidence about the effect of several inputs in the education production function,…
