**2. Study of assessment practices in problem-solving**

In the canton of Geneva, in the French-speaking part of Switzerland, grade 8 students (13–14 years) in the science stream have a 45-minute period per week dedicated to mathematical problem-solving. As part of this course, entitled "Démarches mathématiques et scientifiques" (mathematical and scientifical approaches (MSA), teachers are required to assess their students' problem-solving skills on a certifying basis. However, the instructions governing this course are vague, leaving teachers a great deal of freedom as to how they wish to organize and manage their teaching and the associated assessment. It is in this context that Chanudet has studied the ordinary practices of teachers, focusing in particular on their assessment practices. Her work focuses on an analysis of the mathematics teachers make their students encounter, and the way they organize and manage such sessions dedicated to problem-solving, with a focus on the assessment dimension of their practices.
