Assessment for learning (AfL) can facilitate students' development of metacognition. However, teachers often struggle with the implementation of AfL in their classroom. The dynamic approach can help teachers develop professionally in the complex competency that is AfL. The dynamic approach is based on four principles: (a) addressing the…

Worry is an important mediator in the relation between stressors and health. This pilot study examined whether a smartphone-based in time worry-reduction training was feasible and improved physiological health (i.e. increased heart rate variability [HRV]). A total of 26 high-worriers were randomised to an experimental or active-control condition…

This article reviews research on the achievement outcomes of elementary mathematics programs. 85 rigorous experimental studies evaluated 64 programs in grades K-5. Programs were organized in 6 categories. Particularly positive outcomes were found for tutoring programs. Positive outcomes were seen in studies focused on professional development for…

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)…
