Abstract :The main purpose of this study is to examine sixth grade students' problem classification abilities on proportional reasoning problems and whether problem solving strategies and success rates change with problem type and number structure of the problems. This study considered 165 randomly selected students of grade six studying in middle schools in a southern province of Turkey during academic year 2013-2014. A problem test including proportional (missing value, numerical comparison, and qualitative prediction and comparison problems) and non-proportional word problems was designed as a data collecting tool for the research. Number structures that involve within integer, between integer, both within and between integer and non-integer relations were also included in the problem test. The subjects of the study were divided into two groups. Half of the students solved the problem test first and then did the classification task (SC-condition), while the other half solved the problems in the reverse order (CS-condition). Strategies used in solving problems with different types and number structures were identified by evaluating students’ answers on problems. Besides, comparisons among different categories Descriptive data analysis methods were used for this purpose. Analysis show that the problem classification skills of sixth grade students are in average level, and problem type, and number structure of the problems affect the problem solving success.Keywords : Problem Solving, Proportional Reasoning, Problem Classification, Problem Solving Strategies, Number Structures of Problems
