Problem solving plays an important role in mathematics and should have a prominent 
role in mathematics education of secondary students. Many researchers believe that 
mathematical investigation is open and it involves both problem posing and problem solving, but 
some teachers have taught their students to investigate during problem solving. In this paper, we 
discuss the relationship between problem solving and investigation by differentiating 
investigation as a task, as a process and as an activity, and we show how the process of 
investigation can occur in problem solving.
