| Data: | 2019 |
| Resum: | 104 students aged 8 to 16 worked on one Fermi problem involving estimating the number 19 of people that can fit in their school playground. We present a qualitative analysis of the 20 different mathematical models developed by the students. The analysis of the students' 21 written productions is based on the identification of the model of elements distribution 22 and the strategy used. The results show how the students adapt their solutions in order to 23 tackle the problem from their available knowledge. Indeed, younger students have 24 important difficulties to deal with two-dimensional mathematical contents, but they 25 overcome them by simplifying the problem. Finally, we also discuss the possibilities of 26 using the proposed problem as part of a sequence to promote mathematical modelling in 27 each educational stage, in basis of the potentialities identified in our analysis. |
