Background: Providing a rich home literacy environment (HLE) is considered to contribute to the development of students' reading comprehension. However, less research attention has been given to the underlying mechanisms that influence this relationship, including potential mediating characteristics. The present study aims to assess whether…

Background: Reading and reading comprehension are crucial skills, yet many students in grade 4 struggle with them. To address this, several instructional practices have gained popularity. For one, explicit reading strategy instruction (ERSI) is deemed useful, given the finding that successful readers tend to employ reading strategies. As a second…

This study examines the way teachers make sense of data in the context of high-stakes decision making, such as decisions related to student placement in educational tracks. Different types of data, data collected rationally and intuitively, may be used in this sensemaking process, and the same data may be interpreted in different ways by different…

PIRLS (Progress in International Reading Literacy Study) is the fourth assessment in the current trend series, following PIRLS 2001, 2006, and 2011. There were 61 participants in PIRLS 2016, including 50 countries and 11 benchmarking entities (e.g., regions of countries as well as additional grades or language groups from the participating…

PIRLS 2016 data from eight education systems were used to examine how teachers from three different language groups differed in their teaching of reading literacy. Teaching reading practices differed substantially between the three linguistic/cultural groups. In English-speaking systems, effective practices for establishing reading literacy seem…

Numerical understanding and arithmetic skills are easier to acquire for whole numbers than fractions. The "integrated theory of numerical development" posits that, in addition to these differences, whole numbers and fractions also have important commonalities. In both, students need to learn how to interpret number symbols in terms of…

This study investigated the effect of class practices on students' learning gains in reading comprehension in the 5th grade. A sample of 4,344 students in 283 classes in 176 schools was studied. Several class practices that have previously been demonstrated to be effective were tested while controlling for student characteristics and socioeconomic…
