Open mathematical modelling problems that can be solved with multiple methods and have
multiple possible results are an important part of school curricula in mathematics and …

This paper focuses on in-service teacher education as a crucial agent in driving educational
paradigm shifts for the teaching and learning of mathematical modelling. Our paper presents …

Although it is a challenge for primary school teachers, real-context estimation problems can
be used as an introduction to mathematical modeling. With this aim, we designed a two …

This study presents a teaching experiment in which second-grade primary school students
compared a city and a town according to population estimates. The activities were presented …

This paper presents a qualitative study developed with a group of 16-year-old students who
were asked to estimate large numbers of elements on a bounded surface. Taking the …

Previous research has highlighted the importance of social relationships in mathematical
group work while working on modelling activities. This study analyses the interaction of sixth …

Over the course of this study, we analyze the problem-solving schemes proposed for two
sequences of estimation problems. In the first sequence, the problems ask for estimates …

This work describes how the combination of the mistakes committed by a group of pre-
service teachers when solving a Fermi problem, with the representation of the temporal …

Los problemas de estimación en contexto real pueden utilizarse como iniciación en la
elaboración de modelos matemáticos. En este estudio se recogieron los planes de …

Creating and developing mathematical models to solve real-world problems is a complex
task and students often have difficulties in tackling it successfully. The design and …
