- Abstract
- The purpose of this study was to identify characteristics of middle
school students proportional reasoning. The participants were 70 7th
grade, 68 8th grade, and 69 9th grade students in Seoul. This study
was conducted using written test to analyze students proportional
reasoning strategies and interview to investigate their thoughts.
In the results, there was no statistically significant difference
between the grades. Also the students often chose solving strategies
depending on the context of the problems, and they showed a lack of
multiplicative understanding. In conclusion, we identified a
pseudo-formal stage, which jumps from the additive strategy to the
formal strategy with procedural understanding and not conceptual
understanding. Therefore the multiplicative strategy could serve the role
of a bridge from an additive strategy to a formal strategy on
proportional reasoning.
