We investigated whether Early Algebra lessons that explicitly aimed to elicit mathematical discussions (Shift-Problem Lessons) invoke more and qualitatively better mathematical discussions and raise students’ mathematical levels more than conventional lessons in a small group setting. A quasi-experimental study (pre- and post-test, control group) was conducted in 6 seventh-grade classes (N =160). An analysis of the interaction processes of five student groups showed that more mathematical discussions occurred in the Shift-Problem condition. The quality of the mathematical discussions in the Shift-Problem condition was better compared to that in the Conventional Textbook condition, but there is still more room for improvement. A qualitative illustration of two typical mathematical discussions in the Shift-Problem condition are provided. Although students’ mathematical levels were raised a fair amount in both conditions, no differences between conditions were found. We concluded that Shift-Problem Lessons are powerful for eliciting mathematical discussions in seventh-grade Shift-Problem Early Algebra Lessons.

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 each in which twelve primary school teachers took part over a period of six months. It centralised the language support that pupils need to reason during science lessons. In line with the idea of scaffolding, the structure of the PDP targeted teachers' gradual independence in designing lessons. The first research question is how scaffolding was enacted during the PDP. The analysis of video recordings, field notes, researcher and teacher logs, and teacher design assignments focused on the enactment of three scaffolding characteristics: diagnosis, responsiveness and handover to independence. The second research question concerns what teachers learned from the participation in the PDP that followed a scaffolding approach. The data analysis illustrates that these teachers had learned much in terms of designing and enacting language-oriented science lessons. In terms of diagnosis and responsiveness, our PDP approach was successful, but we problematise the ideal of scaffolding approaches focused on handover to independence.

This paper explores whether constitutional litigation contributes to sustaining the equity element of the right to health. Equity entails a fair distribution of the burden of healthcare financing across the different socio-economic groups of the population. A shift towards uncontrolled private healthcare provision and financing raises equity challenges by disproportionately benefitting those who are able to afford such services. The extent to which equity is enforced is an indicator of the strength of the right to health. However, do domestic constitutional courts second-guess, based on equity, policy decisions that impact on healthcare financing? Is it the task of constitutional courts to scrutinize such policy decisions? Under what conditions are courts more likely to do so? The paper addresses these questions by focusing on the case of Hungary, where the right to health has been present in the Fundamental Law adopted in 2010 and the Constitutions preceding it. While the Hungarian Constitutional Court has been traditionally cautious to review policy decisions pertaining to healthcare financing, the system has been struggling with equity issues and successive government coalitions have had limited success in tackling these. The paper discusses the role of constitutional litigation in addressing such equity concerns. In doing so, it contributes to the discussion on the role of domestic constitutional courts in the protection of social and economic rights.
