Quantitative analysis of the correlation between body posture quality assessment scores and handwriting quality measures

Pierre Dillenbourg, Chenyang Wang, Barbara Bruno, Daniel Carnieto Tozadore

Various technological applications for body posture correction have been proposed in order to improve handwriting or facilitate its learning for children, under the assumption that a better posture promotes better handwriting. However, very little research ...

Modelling the sustainability of a primary school digital education curricular reform and professional development program

Francesco Mondada, Laila Abdelsalam El-Hamamsy, Morgane Solène Denise Chevalier, Jessica Elke Dehler Zufferey, Barbara Bruno, Emilie-Charlotte Monnier

Sustaining changes in teachers’ practices is a challenge that determines the success of curricular reforms, from which Digital Education (DE) is not exempt. As the literature on sustainability is considered “scarce” and “scattered”, long-term studies model ...
