Eighth grade students’ proportional reasoning: Strategies used in missing value and comparison problems
Résumé
The present study investigated 8th grade students’ proportional reasoning through the strategies they used in different types of problems - missing value, missing value followed by inference and comparison problems. One hundred fourteen 8th grade students at five middle schools in Ankara, Türkiye participated in the study. They solved the 10 proportion problems in the test prepared by the authors. Students’ proportional reasoning was analysed considering the set of strategies and the types of problems. Findings revealed that students were flexible in using different strategies to solve proportional problems and different problem types promoted different strategies so different proportional reasoning.
