Studies on the relation between children's reading motivation and early developmental stages of reading competence are rare and have neglected on-line measures of reading skill (e.g., eye movements indicating word decoding). For this reason, we investigated the effects of intrinsic and extrinsic reading motivation on the efficiency of reading…

Academic language and its associations with school success have been established in many prior studies. However, the scholarship lacks research on the mechanisms that constitute these relations. This study investigates the mediating role of motivational-­affective variables, specifically reading self-concept and reading enjoyment, in relations…

Previous studies mostly examined the role of orthographic knowledge in basic reading processing (i.e., word-reading), however, regarding higher reading processing (i.e., sentence- and text-comprehension), mixed results were reported. In addition, previous research in transparent languages, such as German, focused mostly on typically skilled…

In most general education classrooms in Germany, students with and without special educational needs are taught together. To support teachers in adapting instruction to these heterogeneous classrooms, we have developed learning progress assessment (LPA) and reading instructional materials, the "Reading Sportsman" (RS), in line with the…

Developmental Coordination Disorder (DCD) and Attention Deficit Hyperactivity Disorder (ADHD) often co-occur and are associated with specific learning difficulties. Robust prevalence estimations do not yet exist. We studied how symptoms of DCD and/or ADHD are related to difficulties in reading, writing, and mathematics. Using the data from a large…

Scientific reasoning abilities are already developing in elementary-school-aged children and enable them to understand the world around them. The goal of the current study was to develop a new instrument for 8- to 10-year-old children in Grades 3 and 4 to measure their understanding of the steps of the "scientific inquiry cycle" (SIC).…

If children fail to understand test instructions, measurements of their competence may be unfair and invalid. This is especially relevant for students with special educational needs (SEN) because they face greater challenges in comprehending instructions. Two interventions were designed to facilitate the comprehension of test requirements by…

This study addressed the role of reading motivation as a potential determinant of losses or gains in reading competence over six weeks of summer vacation (SV). Based on a sample of 223 third-grade elementary students, structural equation analyses showed that intrinsic reading motivation before SV contributed positively to both word and sentence…

Two studies were conducted to investigate effects of domain knowledge on metacognitive monitoring across the life span in materials of different complexity. Participants from 4 age groups (3rd-grade children, adolescents, younger and older adults) were compared using an expert-novice paradigm. In Study 1, soccer experts' and novices'…

The "acceleration phenomenon" (AP) is defined by improvements in reading speed and reading comprehension, induced by an artificial text fading procedure corresponding to the previously determined fastest individual reading rate. Recent results, however, indicated that fading that is slower than the self-paced reading rate can produce…

Experimentation skills are a central component of scientific thinking, and many studies have investigated whether and when primary-school children develop adequate experimentation strategies. However, the answers to these questions vary substantially depending on the type of task that is used: while discovery tasks, which require children to…

Lexicon Pirate was originally developed as a strategy intervention programme to treat lexical disorders of pre-school children. To evaluate the therapy's effectiveness for school-age students, a randomized controlled trial (RCT, N = 157) was conducted. Based on a pre--post-test design, the programme's impacts were compared with a control group…

Monitoring the learning progress of at-risk students positively affects learning growth. This study transfers the approach of learning progress assessment (LPA) to general education in Germany and investigates the effects of information about reading progress and additional teacher training on student achievement. Classes (n = 43) were assigned to…

According to the Matthew effect model, interindividual differences in reading competence between poor and normal readers should become wider as students grow older. The second part of the model assumes that these differential pathways are mainly attributable to differential reading activities. The purpose of this study is to examine whether both…

Cross-language effects on reading skills are of particular interest in the context of foreign language immersion programs. Although there is an extensive literature on cross-language effects on reading in general, research focusing on immersion students and including different dimensions of reading acquisition such as reading fluency and reading…
