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 ...

The Child-Robot Relational Norm Intervention to Promote Correct Handwriting Posture for Children

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

Persuasive social robots have the ability to influence human behaviour through social interaction, which makes them a valuable technological solution for all applications aiming to support a person's behaviour change. The recently proposed Child-Robot Rela ...

The Competent Computational Thinking Test (cCTt): A Valid, Reliable and Gender-Fair Test for Longitudinal CT Studies in Grades 3-6

Francesco Mondada, Jessica Elke Dehler Zufferey, Barbara Bruno, Laila Abdelsalam El-Hamamsy

The introduction of computing education into curricula worldwide requires multi-year assessments to evaluate the long-term impact on learning. However, no single Computational Thinking (CT) assessment spans primary school, and no group of CT assessments pr ...

WriteUpRight: Regulating Children’s Handwriting Body Posture by Unobstrusively Error Amplification via Slow Visual Stimuli on Tablets

Pierre Dillenbourg, Barbara Bruno, Daniel Carnieto Tozadore

Maintaining a proper body posture during interactions with educational tablet applications is crucial for children's physical well-being and task performance, especially considering digital tablet's increasingly pervasive use in classrooms. In this work we ...

An HMM-based Real-time Intervention Methodology for a Social Robot Supporting Learning

Pierre Dillenbourg, Mortadha Abderrahim, Barbara Bruno

To make social robots effective in education, they need to be autonomous both in terms of assessing the student's engagement state as well as intervening effectively in soft real-time when necessary. Hidden Markov Model (HMM) is an interpretable machine le ...

The iReCheck project: using tablets and robots for personalised handwriting practice

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

Handwriting is an important skill in children development as well as in education that take years to be mastered. While keyboards and similar technological devices increasingly become more popular, new tools and engaging approaches are also required to kee ...

A Research-Practice Partnership to Introduce Computer Science in Secondary School: Lessons from a Pilot Program

Francesco Mondada, Helena Kovacs, Jean-Philippe Pellet, Jessica Elke Dehler Zufferey, Barbara Bruno, Laila Abdelsalam El-Hamamsy

Context: Introducing Computer Science (CS) into formal education can be challenging, notably when considering the numerous stakeholders involved which include the students, teachers, schools, and policy makers. We believe these perspectives should be con ...

Unobtrusively Regulating Children’s Posture via Slow Visual Stimuli on Tablets

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

Children’s retention of a proper body posture while interacting with educational tablet applications is important for both their physical health and task performance. In this work, we propose a new approach to unobtrusively induce postural changes in child ...

DRONE GAME THAT HIGHLIGHTS ETHICAL AND SUSTAINABILITY IMPLICATIONS OF DESIGN DECISIONS

Siara Ruth Isaac, Jessica Elke Dehler Zufferey, Gianni Lodetti, Barbara Bruno

This paper reports on the development of a brief scenario-based challenge to prompt engineering students’ reflection about the broader impacts of their design decisions, and thereby increase their ethical sensitivity and motivation. The game scenario asks ...
