Mathematics is of major importance in science subjects. Unfortunately, students struggle with applying mathematics in science subjects, especially physics. In this qualitative study we demonstrate that transfer of algebraic skills from mathematics in physics class can be improved by using pre-knowledge effectively. We designed shift-problems…

In this study, longitudinal cohort-sequential latent growth modeling was used to determine the effects of (a) socioeconomically mixed preschool and kindergarten classrooms, (b) the implementation of an education program aiming to accelerate socioeconomically disadvantaged children's emergent academic skills, and (c) the amount of teacher-managed…

Schools frequently increase the instructional time to improve primary school children's math and reading skills. There is, however, little evidence that math and reading skills are effectively improved by these instruction-time increases. This study evaluates "Playing for Success" (PfS), an extended school day program for underachieving…

Solving word problems plays an important role in primary school mathematics education. However, many students have difficulty solving such tasks. In order to improve students' metacognitive and problem-solving skills, a computer program was developed consisting of word problems and metacognitive hints. The experimental group of Grade 5 (n = 23)…

This study examined whether the effects on cognitive and language outcomes of a recently developed home-based educational intervention program, Opstap Opnieuw, for 4-6-years-old disadvantaged children could be explained by improved mother-child interaction. The present sample (n = 30) was drawn from a larger sample of Turkish-Dutch families (n =…
