In this study, the authors empirically tested a theoretical model based on the one suggested by Lamon, who claimed that the development of proportional reasoning relies on various kinds of understanding and thinking processes.
The critical components suggested were individuals’ understanding of the rational number subconstructs, unitizing, quantities and covariance, relative thinking, measurement and “reasoning up and down”.

The authors also used an extended model which included an additional component of solving missing value proportional problems.
Data were collected from 238 prospective kindergarten teachers.

To a great extent, the data provided support for the extended model.
These findings allow the authors to make some first speculations regarding the knowledge that prospective kindergarten teachers possess in regard to proportional reasoning and the types of processes that might be emphasized during their education.
