ab: Summary: In this study, we report on an analysis of the mathematization
processes of one 6th and one 8th grade group, with emphasis on the
similarities and differences between the two groups in solving a
modeling problem. Results provide evidence that all students developed
the necessary mathematical constructs and processes to actively solve
the problem through meaningful problem solving. Eighth graders who were
involved in a higher level of understanding the problem presented in
the activity employed more sophisticated mathematical concepts and
operations, better validated and communicated their results and reached
more efficient models. Finally, a reflection on the differences in the
diversity and sophistication of the constructed models and
mathematization processes between the two groups raises issues
regarding the design and implementation of modeling activities in
elementary and lower secondary school level.
