Meertaligheid in het onderwijs is eerder regel dan uitzondering. Door toegenomen mobiliteit en nieuwe media komen tegenwoordig bijna alle kinderen in aanraking met meerdere talen en dialecten. Thuis, op straat, in de speeltuin en op TikTok gebruiken ze ál hun talen. Op school gebruiken ze vooral Nederlands. …

Many students persistently misinterpret histograms. This calls for closer inspection of students’ strategies when interpreting histograms and case-value plots (which look similar but are diferent). Using students’ gaze data, we ask: How and how well do upper secondary pre-university school students estimate …

This systematic review aims to take stock of the current knowledge regarding the possible processes, challenges, favourable conditions, and potential for change involved in translanguaging within and across learning settings in the case of multilingual children with a migration background engaged in …

Science museums can be a rich learning context, where visitors engage with scientific practices with few formal requirements. However, science museums can be experienced as not welcoming to migrant families due to social, economic, and cultural barriers. In this study, we asked what language-related …

Het W&T-onderwijs op de basisschool kent verschillende uitdagingen, die we in deze ontwerpstudie aangaan door begrips- en (vak)taalontwikkeling tegelijkertijd te ondersteunen. Daartoe ontwikkelden we een taalgerichte lessenserie die het leren verklaren van drijven en zinken, en de daartoe benodigde denkstappen, …

It has been argued that teachers need practical principled knowledge and that design research can help develop such knowledge. What has been underestimated, however, is how to make such know-how and know-why useful for teachers. To illustrate how principled knowledge can be “practicalized”, we draw on …

This article reports on a post hoc study using a randomised controlled trial with 31,842 students in the Netherlands and an instrument consisting of 21 paired problems. The trial showed a variability in the differences of students’ results in solving contextual mathematical problems with either a descriptive …

The purpose of the design-based research reported here is to show – as a proof of principle – how the idea of scaffolding can be used to support primary teachers in a professional development programme (PDP) to design and enact language-oriented science lessons. The PDP consisted of six sessions of 2.5 h …

Research on solving mathematical word problems suggests that students may perform better on problems with a close to real-life representation of the problem situation than on word problems. In this study we pursued real-life representation by a mainly depictive representation of the problem situation, …
