Abstract
The purpose of this research was to develop mathematical thinking in statistics topic for ninth grade students through problem–based learning. The participants consisted of 21 ninth grade students who studied in the second semester of the 2019 academic year. The research instruments were lesson plans, worksheets, a mathematical thinking test, and an interview. The data were analyzed using content analysis.
The results revealed that: before students studied with problem-based learning, they solved problems by copying the content from the problem and identify the wrong methods. They also used their personal thoughts and false representations during solving problems. During studying with problem-based learning, students solved problem by separating content in the problem into small parts and they could choose the appropriate problem solving method. They could explain the reason for not choosing the other methods and they had better mathematical thinking on representation. At the end of the study, students had better mathematical thinking on problem solving. They could identify the problem correctly and chose proper problem solving method. They had good mathematical thinking on reasoning competence and mathematical thinking on representation. Students could represent their thinking through words, graph, and mathematical symbols.
